FAQ

Features

Does U-RENDER support 360/180° spherical cameras?

We are researching spherical rendering. First we want to get the basics right though.

Does U-RENDER support spline/hair rendering?

Right now the renderer does not support spline rendering. This is something we have on our roadmap and requires further research.

Is U-RENDER an GPU or CPU renderer?

U-RENDER uses OpenGL - so it is GPU based.

As it makes use of the OpenGL API it can utilize any graphics card that supports OpenGL 4.5 or later.

Is particle rendering supported?

Particles are not planned for the initial version as we want to focus on getting all the basics right. We are planning about supporting particles in a later version though. We want to support popular and powerful plugins like X-Particles as well then.

Is this a replacement for the Cinema 4D viewport?

No, U-RENDER integrates as third party renderer into Cinema 4D. It is not a replacement for the viewport. You can render your scenes using your familiar workflows.

Light and Shadows

Does U-RENDER have Area Shadows?

We have soft shadow maps right now and are continuously researching high quality shadow algorithms to provide high quality results.

Does U-RENDER support volumetric lights?

Volumetric rendering is something we have on our roadmap for future version. For a start we a busy enough to get all the expected features right and integrate them into a familiar Cinema 4D workflow.

Materials and Shaders

What materials and shaders does U-RENDER support?

U-RENDER is using physically based rendering. We have implemented both specular/glossiness and metallic/roughness workflow. Choose whatever fits your need on a per-material basis.

Will U-RENDER support Cinema 4D shaders / materials?

U-RENDER requires it’s own materials as it is an OpenGL based renderer. Cinema 4D’s shaders are all CPU based an need certain information at render time.

U-RENDER can automatically bake Cinema 4D’s shader into textures and transfers them to the real-time renderer. Effects that require render time information can be lost.

We are also working on converters from Cinema 4D materials so that all common parameters are transfered.

Requirements and Platforms

Does U-RENDER support AMD cards?

Yes! U-RENDER uses the OpenGL standard so all cards that support modern versions of OpenGL will be supported. We are actively testing the renderer against modern AMD and Nvidia cards.

Here is a list of cards we are currently testing:

  • AMD RX 480
  • AMD R9 380
  • Nvidia GTX 1080
  • Nvidia GTX 1060
  • Nvidia GTX 970
What versions of Cinema 4D are supported?

We are currently looking to support Cinema 4D R16 and newer.

Will there be a macOS (Mac OSX) version?

Right now we are developing for Windows PC. We have not decided on a macOS version yet. The increasingly lacking support of industry standard APIs and a limited choice of graphics hardware are severe constraints.

Will there be support for Houdini, Modo, 3dsmax, Maya?

Right now we focus on developing the Cinema 4D version. We plan to support other tools once we will have released the first version of U-RENDER.
