How to add water droplets in Blender

water drops in blender
In this tutorial you will learn to add static water droplets in Blender. You will learn to 
add particles
hair particles
instancing
instance scale and rotation settings.
Software used : Blender 2.70 64 bit
Difficulty        : Beginner
Download       : Start scene Finished scene

Adding static water drop in Blender is relatively easy in Blender. But if you need the dynamic water drops, it is very complicated. However I found a way to do that. May be in the next tutorial I will discuss that. Adding static water by particle instancing is the great way to achieve believable effect with less time. In this tutorial I just used a single sphere for instancing. For more realism you can use different shaped water droplets(you need to sculpt/model it). In order to use different models at a time for instancing you need to group it and use that group under particles instead object.
You can use the scene file and study the techniques.Hmm...It is very basic.

Basics :Blender for motion graphics #1

This is the first chapter of Blender for motion graphics ebook
This chapter deals with the basics of Blender.
First thing you need to get a latest Blender version for your current operating system. I am using Blender 2.68a. Optionally update your OS and drivers so Blender works fast in your system.
Open Blender by double clicking the icon or from start menu. You will be greeted with a splash screen.
blender splash fermicg
According to your Blender version the splash screen varies. Splash screen contains several useful links. Get rid of the splash screen by left clicking [LMB] out the splash screen. You can see a cube, camera, and light and a 3d cursor. See the image below.
blender default fermicg
Blender has annoying UI (for me), so I always set it my own preferred way so it behaves like other 3d applications. Blender uses Right click [RMB] for selection LMB for other purpose! If you use other 3d software or
graphics applications, this will create problem. So we need to change.
Go to File→user preference [CTRL+ALT+u]
blender user preference fermicg
select the interface tab and turn on “rotate around selectionand “Prompt Quit”(only available in Windows).
blender interface preference fermicg
Blender will quit without any warning if you click the close button. If you chose the prompt quit Blender will give a warning message before closing. Only for Windows users!
In the input tab you can select different preset for keyboard shortcuts and navigation. Here we are going to change the RMB issue. Depending on the Blender build, you may get 3ds Max, Blender and Maya. SVN and Graphicall build may contain more preset. Simply select Maya for navigation preset. This is the best navigation option than default Blender setting. Throughout this book I am using Maya view port navigation setting. Do not change the keyboard layout because we are using default Blender settings. If you are using laptop turn on “emulate keypad”.
blender input fermicgIn the theme tab chose the theme of your choice. I am using default one.
In the file menu, choose the path for fonts, texture, and sound, render output etc. Depending on the OS the path varies. You must choose the font folder in order to follow this book.
For Windows : C;/windows/fonts
For Linux : /usr/share/fonts/
blender  fonts fermicg
In the system tab, turn on CUDA under compute device.
Finally save user settings and close user preference dialogue.

How to enable CUDA in Linux (Ubuntu) for Blender

You can easily enable CUDA in Ubuntu. CUDA is capable of delivering faster render in supported GPU.
First of all make sure that you have CUDA supported Nvidia graphics card. If so connect to Internet,

Open Ubuntu software center.
Go to editsoftware sources→other software
and turn on
Canonical partners and independent
Save and close.
Open terminal and type
“sudo apt-get update” .
Press enter and give password for root. Wait for the update to finish. Then type
“sudo apt-get install”
Press enter and wait for the installation to finish. Close the terminal and reboot.
You can use Ubuntu DVD also if you haven't internet connection. Just turn on DVD as installation media.
Open Ubuntu software center.
Go to editsoftware sources→Additional drivers
And look for available nvidia drivers. If found any install the latest proprietary driver. (you wont get the latest as from the developers site).
If you can't find any drivers,
In the Ubuntu software center search for “ additional drivers” and click on that link. Install or use this source. Restart your computer and repeat the steps.

Once installed you need to restart your computer to get the driver to work properly.
Open a new Blender, turn on CUDA and do a test render with GPU. You will get the GPU render.
If the render yields only black output you need to add some libraries.
Open terminal and type

“sudo apt-get install freeglut3-dev build-essential libx11-dev libxmu-dev libxi-dev libgl1-mesa-glx libglu1-mesa libglu1-mesa-dev”

then
“sudo apt-get update”
“sudo apt-get install”
Reboot your computer. CUDA will work perfectly.
Some times you may not get the correct CUDA rendering. Then you need to update Blender first. Update nvidia driver manually.

Update nvidia driver manually.

You can get the latest nvidia driver by manual installation. But you need to manually install the driver whenever you update your Linux kernel.
Download latest nvidia driver from manufactures website. Select the correct version suited for your system (32/64).
Copy it in desktop and rename to nvidia.run
Press CTRL+ALT+F1.
Login with your user name and password.
Then type
sudo service lightdm stop”
then
“cd Desktop”
“sudo ./nvidia.run”
carefully follow the on screen instructions and install the driver.
You will get several error message. Proceed further by clicking ok until you reach installation can continue.
Type
“sudo reboot”.
After reboot repeat the process from CTRL+ALT+F1
Follow the onscreen instructions and you can successfully install nvidia driver.
 Once finished either you can restart or start using your desktop by typing
sudo service lightdm start”

Windows vs. Linux in 3d rendering

Which operating system is the best for rendering? A question I often ask and search; I think it is often asked by you also. Ok, what is the answer?
In my experience Linux is 1.62X or 62% faster than windows. That means Linux can render more than 3 frames where Windows can render only 2 frames at a given time. Unfortunately I don’t have a Mac computer, so it is not in the comparison list.
The operating system or OS included in this test are
  • 1. Microsoft Windows 7 64 bit
  • 2. Ubuntu studio (Linux) 13.04 64 bit
3d application used
  • Blender 2.68 a 64 bit
Rendering software used
  • Cycles render (pre installed with Blender).
All the tests are done on a multi boot single laptop. The hardware configurations are
  • Dell XPS 14 laptop
  • Intel core i7 processor with 1.74 GHz speed.
  • NVidia GT 425M Graphics card
  • 4 GB DDR3 RAM 1333 MHz
  • 500 GB HDD 7200 RPM
Display Drivers used,
  • NVidia display driver 314.07 for Windows 7
  • NVidia Binary display driver 310 for Ubuntu
You can see, the hardware components are identical. The scene file used is the same for both operating systems. 3d program used is the same for both OS.
Here is the final render.
rbcs on glass bottle
Here are the details of the scene.
  • A photorealistic (?) glass bottle with studio lighting.
  • Dynamically driven RBCs are present inside the bottle.
  • All the materials used are Cycles shaders.
  • Indirect lighting with full global illumination.
  • Total samples of 1000 are used in rendering.
  • Total number of polys includes 8072. Total size of the scene is 1.64 MB.
  • The final output is HD 720P i.e. 1280x720.

Conditions
Windows 7 64 bit
Ubuntu studio 64 bit
Before optimizing the PC
Total RAM usage
1.52 GB i.e. 38% 360 MB i.e. 9%
After optimizing the PC
Quit unwanted programs and services, total RAM usage
1.06GB i.e. 26.5% No optimization performed
After opening the scene in Blender total RAM usage 1.48 GB 37% 548 MB 13.7 %
During rendering RAM usage 1.44 GB 36% 520 MB 13%
During rendering CPU used for Blender 98-99% Rest is reserved for system. 97-98% Rest is reserved for system
Total render time 18 minute 12 seconds 11 minute 16 seconds

So Linux is the winner in 3d rendering race.
Unfortunately CUDA rendering is not working in Ubuntu studio (I need to add some CUDA libraries in Ubuntu). So there is no test for CUDA or GPU rendering. May be in some other time.

Update

OK, I successfully updated my CUDA driver in Linux.See how I enabled CUDA in Ubuntu Now it is perfectly working. So what? I rendered the above scene in Blender using GPU in both Linux and Windows. Surprisingly the result is almost same! A slight performance gain in Windows.

Windows 7 64 bit
Linux Ubuntu Studio 64 bit
GPU rendering (CUDA)
12.53 Minutes
12.58 Minutes
So for GPU rendering, Windows 7 64 is the winner (with photo finish).
I think it is because the CUDA driver and graphics card driver have better optimization in windows than Linux.

Conclusion

According to my hardware specification Ubuntu CPU rendering is the fastest.
Here is the final comparison,
1st prize
Ubuntu 64 CPU rendering
  11.16 minutes
2nd prize
Windows 64 GPU rendering
12.53 minutes
3rd prize
Ubuntu 64 GPU rendering
12.58 minutes
4th prize
Windows 7 64
18.12 minutes

I also noticed that Maya also have a clear performance boost in Linux environment. But Maya will work only in RPM based Linux environment. For Maya Cent OS is the best.
I don’t know about Mac OS.
Have you ever feel slow rendering? Try switching your operating system first. Then upgrade your hardware.
So what you think? Post your comments and result below.

Render Layer in Cycles Blender tutorial

Blender is an awesome free 3d application which provide similar functionality like Autodesk Maya, 3ds Max and Cinema 4d. Blender is a powerful easy to use 3d application if learned wisely. If you are a user of other 3d application you may get confused with nonstandard GUI, keyboard shortcuts and lack of well detailed documentation.
I was one of the failed Blender climbers who tried several times Blender before. But being stuck with Autodesk Maya, it was a pain to learn other 3d software. I even tried Cinema 4d which is very easy to learn but failed. So I understood that Blender is not hard but my love for Maya is so strong. So I just started using Blender in my home and production and soon I get used with Blender. Now I can make motion graphics with Blender easily and am still learning it. Anyway during my experiments with Blender I found that there are so many gaps in the area of Blender tutorials. So I am adding more tutorials about Blender.

blender render layer
Enough introductions. We can now learn to use Blender render layers efficiently in production. Don’t expect very complex set up, but I will guide you through three cubes in a scene and with render layers. It will be easy to follow and understand. I am adding a text version but I recommend watching the video tutorial.

Author : FermiCG
Software : Blender 2.68a
Difficulty : Beginner
Download : Render Layer cubes finished.blend
Blender has a well coded render layer, render passes and compositing work flow. Once you learn how things works inside Blender it is easy to use and straight forward than Maya’s render layer system.
This tutorial is based on blender 2.68a.But 2.6x series will work fine. If you don’t have blender download it free from blender.org.
 
Start with a new scene. You will get a default cube, camera and a light. Select the cube and add a new material and change the colour to red. (Find the material tab and press the + button and add a material. Change the diffuse colour to red.). materials in blender
In viewport duplicate the cube (shift +d) and delete the existing material by clicking – button on material tab. Add a new material and change colour to green.
Duplicate the cube again and replace the material with blue one.
Place the cubes in such a way that they intersect each other. See the image.
materials in blender
Press 0 to look through the camera. If needed, adjust the camera so three cubes are in focus.
materials in blenderWe are going to render the scene with cycles. So change to cycles render. Set the quality and dimensions. Optionally you can turn on transparency and RGBA. Press render and see how the render looks.
camera in blenderJump to composite mode and see the connections. You will get a render layer node connected to composite node (just turn on nodes). We need to get three cubes in three different render layers. Back to default view.
composite in blenderIn order to get render layers properly, we need scene layers also. So select the green cube and press M and select 2nd layer. This will cause the green cube to be in 2nd scene layer.
layers in blenderSelect the blue cube and press M and select 3rd layer. You can click on each scene layer to confirm they are in correct order. Select first layer and render. Now we have the red one with lighting. Select second layer and render. 2nd and 3rd layer won’t have any lights or shadow. Select 1, 2 and 3 layer (shift select) and render again. We will get all the cubes with light and shadow.
We successfully created scene layers. But we need render layers. So find the render layer tab in properties menu.
layers in blenderYou can see a drop down window with render layer inside and “+, -“sign outside. This is the render layer tab. Below that you can see layer tab. Expand it and you will get scene, layer, exclude and mask with 20 columns each. They are different render layer settings. The first one scene is same for the scene layer in viewport. You can click on 1, 2 and 3 scene layer to check. The layer in the right is actual render layer. So select the 1st scene layer and rename the render layer to red. Also select the 1st column in layer. Make sure you are not selecting anything else.
layers in blenderSelect the 2nd scene layer and add a new render layer by pressing + button. Rename to green. Select the 2nd column under layer.
render layers in blenderSelect 3rd scene layer and add a new render layer. Rename it to blue. Select the 3rd column under layer.
Select all the three scene layer and render.
render layers in blenderBlender will render the cubes one after other. You may see black holes in render. You will get something similar to this.
render layers in blender
black hole in blenderSwitch to composite view. You can see render layers is connected to composite node. Select the render layers and click on the layers and chose different layer. You can use this for further compositing.
node editor in blenderLeave it to red. Duplicate render layers 2 times (shift +d) and change the 2nd one to green and 3rd to blue. (Shift+ backspace for full view).
render layer nodes in blenderWe need to combine these layers. In order to do so add an alpha over node (add>colour>alpha over)
Now connect the image of red to the bottom image of alpha over node.
alpha over node in blenderConnect green image to the top image of alpha over node.
alpha over node in blenderAdd another alpha over node. Connect the blue image to bottom image of 2nd alpha over node. Also connect image of 1st alpha over to the top image of 2nd alpha over node.
alpha over node in blenderNow we need to connect the 2nd alpha image to the composite node. You can lose the connection between red layer and composite node.
connection in blenderNow we need to check our composition. Add a viewer node. (Add>output> viewer)
 viewer node
Connect the second alpha over image to the image of viewer node.

backdrop in blenderAlso turn on backdrop.
final compositNow we have the composited image. You can swap the connection between render layers with alpha over node. But still you won’t get the original output. The black hole remains there. In order to get rid of those black holes we need to add mask layers. Switch to default view. Select the red render layer (which contains red cube) and under mask layers select 2nd and 3rd columns because we need them as mask for the first layer. Repeat the same for all the layers. Remember you need to choose the layers you want to mask. For green, use 1st and 3rd. for blue use 1st and 2nd.
mask layersRender again to see the magic. Jump to composite mode.
composited renderNow we have the cubes in correct order. You can swap the connection and still the render is the same.
We need to explain one more render layer settings named exclude layer. Exclude layer in Blender is used for excluding something from render. For example we have a plane just intersecting the three cubes. We need to render the plane separately without having any shadow or mask, we can use exclude layer. Additional use of exclude layer can be explored on further tutorials.
So add a plane and place it in such a way that it intersects the cubes and faces towards the camera.
intersectMove it to a new scene layer (4).Add a new render layer named plane. Set the render layer. Don’t use any mask layer.
soloJump to composite mode. Add a new alpha over node and a render layer node. Change the render layer to plane. Connect it to the bottom image of 3rd alpha over node. You need to connect the 2nd alpha over node to the top image of 3rd alpha over node. Also connect the 3rd alpha over to the viewer node and composite node. Render to see the result. You should get something like this.
extra node in blenderWe need the plane as it is. Shift to default view and in the render layer settings select the plane render layer. In the exclude layer select 1, 2 and 3 column. Select the entire scene layer and render again. Now we will get blender tutorial
This concludes the render layer in Blender tutorial.
