Thea Render GPU+CPU hybrid render

Thea render, relatively a young player in the industry. But a strong, well coded solid render which can utilize the CPU and GPU simultaneously. It has both biased and unbiased engines i.e; if you need speed you can use biased engines and if you need quality (photo realistic renders for architecture and product rendering) you can use unbiased engines. The important feature is it can use your processor and NVIDIA CUDA graphics card simultaneously for rendering. If your scene doesn't fit the vram (too heavy for the GPU) Thea can utilize CPU only for rendering and it is even done automatically. Thea has a real time rendering engine like Corona and Octane. It has built in material system which can be used on any software Thea supported (Sketchup, Cinema 4d, Blender, 3ds Max etc.). That means you can utilize the materials created by other users for other software. Thea has its own studio rendering which allow you to import 3d objects, add materials, lights, camera animation and do render.

Ok..here is the real user opinion. I tested Thea for C4D which come with Thea studio and Thea plug in for C4D. You can grab a fully functional water marked Thea render free of cost from their site.

  • Its very easy to use especially Presto engine.
  • Little tweaking needed for materials and render settings
  • Render presets are almost useful for majority of situations
  • Displacements, depth of fields are almost real time.
  • Real time rendering support.
  • Multi pass rendering.
  • Real camera adjustments during rendering.
  • Relight functionality
  • Scene transfer time (preparation time) is very fast, instantly start rendering.
  • Very fast rendering for exterior with physical sun and sky
  • HDRI lighted scene rendering is also fast.
  • Photo realistic rendering with out any manual tweaking
  • Flicker free GI
  • Separate engines suited for different situations
  • Adaptive BSD rendering is very fast with GI scenes.
  • Can render Billions of polys without instancing very easily
  • Instancing support
  • Bucket rendering
  • Net work rendering
  • Support Team render
  • Support Take system
  • Materials can be exchanged through all the supported applications.
  • material system is simple and uses common names
  • Well support by the development team
  • Adding new features and bug fixes are fast


  • Must adhere with real world unit, (if you use 1 meter sphere and 10 meter sphere with same material like colored glass, you will get different result).
  • No Motion blur support for C4D
  • Mograph shaders are not fully supported.
  • You have to stick with real world lighting for good result. That means if you use C4D lights you loose certain functionalities like caustics.
  • Mesh lighting is better than native lights
  • No matte objects supported, that means if you change a texture for one object you need to render all scene (you can add material override manually). but for Vray it is easier.
  • Render passes are limited compared to Vray.
  • Interior lighting is very slow, take too much time for cleaning up noise.
  • For better interior lighting you have to use mesh instead of lights.
  • Complex shading materials are somewhat tricky
  • The reference manual is limited

Well suited render for Architectural visualizations, product renderings and small scale animation. If you are an individual, small studio Thea is a very good companion.

Anyway I will upload more real world scenes and situations. I recommend you to download the demo and test it your selves


Mechanical Animation in C4D

Creating mechanical animation in C4D is very easy. With the help of its robust curve editing tools Mograph and little bit of xpresso you can create accurate mechanical animation with less effort. In this tutorial we will discuss about the basics.
