How many is too many decals?

So, I’m making this super old building, and I’ve been using decals up the booty for moss, leaky stains, holes, cracks, etcetera. And I have no idea if I’m over doing it or not.

Any and all input is greatly appreciated :slight_smile:

What about profiling the scene?
Shader Complexity and Quad Overdraw are Viewports you should look at.
You may also look into ProfileGPU.
It mainly depends on how complex your Materials and your Decals are.

I personally would definitively use Vertex Paint for this instead of Decals.
