To use it you must also set the Blend Mode in the Material Property Overrides to Alpha Composite. |
BumpTex
|
NormalTex
|
Selfillumination
|
We suggest when using SelfIllumination to set the Blend Mode in the Material Property Overrides to Opaque. |
Opacity
|
To use it you must also set the Blend Mode in the Material Property Overrides to Translucent or Alpha Composite. Due to Unreal Engine's limitation when using Translucent blending mode and Two Sided enabled, back faces on two-sided geometry may appear front. To resolve this when using Opacity Tex uncheck the Two Sided option. |
ClearCoat
|
To use it you must set the Shading Model in the Material Property Overrides to Clear Coat. |
VRay2SidedMtl
|
To use it you must set the Shading Model in the Material Property Overrides to Two Sided Foliage. |
