Can't disable Emit on back side when in GPU render mode

[summerson1990]

Hi! "Emit on back side" can't be disabled in GPU mode, it simply doesn't affect, so both sides (front and back) are emissive. With CPU mode everything is fine. So why is this not possible to do when rendering with GPU?

Unfortunately the option is not supported by the GPU engine.
The Core team is aware of that and I'm sure it's going to be supported at one point.

As a workaround:
- Save out the Emissive material as .vrmat
- Open it in a text editor
- Locate a parameter called 'double_sided' and change it's value to '0'
- Save the material and re-load it in SketchUp



This option will make sure that the entire shader is single-sided and will work on the GPU.
