Decals with imperfections, stains, dust, etc. can push render to the next level. Currently those available in Rhino are very limited. Can we have decals with PBR material settings, please? Or simple opacity map to start with.
Also, a couple more options would be handy (toggle on/off, edit mapping type)
Of course, nice thing to have would be decals as separate objects which can cover multiple geometries at once.
