FAQ

Features

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

Yes, U-RENDER supports 360° spherical camera rendering.

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 particle rendering supported?

Particle rendering is one of the next features on our roadmap. We are looking to support popular and powerful plugins like X-Particles as well.

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 but the live mode renders in real-time to the viewport. You can render your scenes using your familiar rendering workflows in Cinema 4D.

Is U-RENDER an GPU or CPU renderer?

U-RENDER uses OpenGL, so it is GPU based. It uses rasterization - like game engines - to achieve render times within milliseconds.

Both AMD and NVIDIA cards are supported.

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?

Yes! U-RENDER supports volumetric rendering. Use volume objects and volume noises to define your participating media volumes. Lights and objects cast shadows into volumes and volumes can cast shadows as well.

See Volumetrics for a full feature list.

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 as well as a hybrid handling of reflectance. 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 realtime 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 from the ray-tracer will be lost.

There is a converter for Cinema 4D standard materials so that all common parameters are transfered to U-RENDER materials.

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.

What versions of Cinema 4D are supported?

Cinema 4D R16 and newer are supported.

Will there be a macOS (Mac OSX) version?

U-RENDER is currently developed and optimized for Windows 10 using industry standard APIs like OpenGL.

We are ourselves avid Mac users and are passionate about the platform. Unfortunately, we do not support macOS for now as Apple has discontinued OpenGL support. This requires to completely re-develop U-RENDER for Metal, which is time consuming.

We are actively working on bringing U-RENDER to macOS but we do not have a date for when macOS support will be available yet as we are still at the beginning of this journey.

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

Right now we focus on developing the Cinema 4D version. A Maya plug-in is next on our roadmap and other applications will be supported in the future.
