[Solved] Deferred projection decal and emission artifacts

Short story, I'm trying to do a deferred projection decal with an emission, and it gets weird edge artifacts when camera is getting further away.

The setup is basic cube for projection, and it seems like it gets self emission lit?

Close up looks like this:


But when zoomed out:


You can clearly see edges on top / left side.

When I enable cube gizmos, it seems like emission is litting top side of the cube, where shouldn't do it.


For the HDR effect, I'm using default Post Processing Stack v2. No LWRP / HDRP, default pipeline.
Can't figure out why it happens though, or how to disable self emission.

 

try to set your textures to clamp and not repeat. Could be mip maps sampling the bottom also.

 

Wow, I really should get proper textures for testing. Thank you, that indeed was the case!
