I turned to two decals method as it is easier to control in any case, but I face another issue, my transparent decal with Affect Base option, diffuse disabled gave the common error message "Affecting only a part of a base material is only supported if both materials are Corona Physical Materials."
It is the material of the sixth bottle from right. Transparent tag appears black. The reason is obvious, there is a layered material on that object, but I need those layers because 3 logos appear one by one on that bottle.
What is the workaround here? Is it again separate decals for layers or is there a switch that handles things automatically.
I'm not being lazy but fear disrupting the complex animations on the object.
