We require very high number of specular depthes for few ESPECIALLY glasses/transparent plastics types such as 3D star's glass... because I detect "blacks" in specular material.
Screenshots - examples: -Blacks detected at 24 specular depthes.

-No any blacks at 115 specular depthes.
NOTE: we need (very) high number of diffuse depthes for avoid caustics missed.
Do you remember this scene (example) by OctaneBench?
Do you like my "teach"?
