Expose occlusion value for underwater or backfaces

[dkyeck]

right now occlusion is set to 0.0 if rendering back faces which kills all reflections when underwater - although we should have "total inner reflections" here. we simply hacked "CrestNodeOcclusion" and set occlusion to 0.45 when underwater but this also reveals ambient diffuse lighting as well. so being able to control backface specular reflection and ambient lighting from the material inspector would be nice.

Thanks for opening. Apologies for the belated reply.

So you want underwater (back face) specific properties for occlusion, specular reflection and ambient lighting? Would ambient lighting be a multiplier, vector or colour?

right now occlusion is set to 0.0. so to start it would be just fine to be able to specify the occlusion value. so a float :)
