Troubleshoot Reflection and Refraction passes render incorrectly with contribution maps

 
 
 

Set this optionVar to produce correct Reflection and Refraction passes with pass contribution maps:

optionVar -iv "beautyPassTypeReflRefrac" 1; 

Setting this optionVar to 1 causes Reflection and Refraction passes for mia_material_x_passes to render black.

To revert to the default behavior, set this optionVar back to 0 as follows:

optionVar -iv "beautyPassTypeReflRefrac" 0;
