I just started a thread here about world aligned texture / world aligned normal in decals behaving strange and I’m assuming it’s related to the vertex normal WS nodes used in those functions but I dont understand why a decal can not extract the propper vertex normal on the surface it’s projecting it seems to only care about a z up orientation regardless of what orientation or surface the decal is being projected onto.
Here’s my thread if you feel it’d be more appropriate to discuss there because mine is specifically about having XYZ or even just XY world aligned decals.
