Working on a mould decal. There is a slider to get different moulds, and a few for adjusting the shape of the decal. In Unreal you can easily instance the substance to get loads of variations with just one import.
The colour is a bit off, partly because of lighting. It would be neat if I can allocate the screws to follow the edges, instead of splattering the same decal around to get the pattern. Its around 80% done. Just some small tweaks to more closely mimic the original.
