I made a simple decal material, set the material domain as deferred decal, both blend modes as translucent, and shading model default lit. I used the Parallax Occlusion Mapping node to give a bit of depth also. The decals work fine, but I noticed that in the areas where my opacity mask is completely white, I can faintly see the object below the decal (for example the standard plane checkerboard). Oh and by the way I enabled DBuffer Decals in my project settings.
I would like to know if this is the way decals are supposed to work or if I did anything wrong, like for example import and use the textures with the wrong type (sRGB, grayscale, linear color, and so on), I kept the material super simple to test this but I can’t figure out what could be wrong. One last note, I also tried to feed a white vector4 to the opacity output, thinking maybe my texture was not completely white, but it changed nothing. I also checked the decal actor options but I didn’t find anything useful.
