Hello! I’ve a optimization question regarding decals!
There is a decal sheet I applied as a material:

Therefore, I dont know whats better, have one material for each art or a main material with this entire texture. Is it possible to clip the bounds of each actor so I can select only the ones I want to use? (that way I would have one single material for them all)

I’ve been researching ways of doing that using the coordinate nodes. Could anyone help me with this? Thanks!

I’m thinking about adding them as separate planes in my modeling program instead of using the decal actors in UE4. I dont know it they would cast shadows depending on the distance from the actual mesh though.

Mesh decals would be perfect for what you’re describing. They are meshes that are rendered as decals, so you can modify your UVs and whatnot to only include part of your decal sheet.
