Hi,
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.
Best regards,
