Currently, some features are "fully supported" only in case of the V-Ray render engine (as you can see in the Feature Compatibility
table, for the rest of renderers it can be enabled by turning off the instancing engine
). Use of features like Material / UVW XForm
Operators are just partially supported.
To get it working correctly with the Corona Renderer, the Use Instancing Engine
should be switched off as shown on the attached screen-shot.
