Do deferred decals somehow batch draw calls? I am curious about placing decals in a scene and wondering if deferred decals add additional draw call per every duplicate decal that is placed. Was wondering if they somehow batch.
The Unreal Engine does a lot of additional work on geometry to draw it in a way that is optimal for the particular graphics platform it’s running on.
I’ve seen demo scenes from Epic and on the marketplace with lots of decals, for each little scuff mark and edge trim and footprint. Seems to work fine.
Unless you have measured that decal instance count is a problem, for example by seeing a large difference in frame rate when decals are on versus forced off, on your target system, I wouldn’t worry about it.
