Skin artefacts - photoshop help needed

[Reflected]

Where metallic and non metallic parts meet, I'm seeing these artefacts. What I do is I click on the layer of the black stripe, it automatically selects it, then on a new layer I paint the non metallic roughmet color. It should therefore be exactly where the black stripe is. But it isn't. So the non metaillic rough met color reaches further, and results in these white edges. I tried to play around with "refine edges" by contracting the selection, but no joy. It's also visible around the "P" on the tail. Any advice please? Thanks!

I get ‘em too with GIMP, but not to that extent. Mostly when working with brighter colours. A trick I use is if the black is supposed to be glossy, I don’t bother putting the marking in the roughmet. Black will look just fine on the skin even without the roughmet version. A matte marking on a shiny surface is a different animal.

 

Now you’ve just reminded me that my Mustang skins are (still) long overdue for an upgrade.

Thanks for the advice. I can’t not put it on the roughmet, because paint is dielectric not metallic. I wish there was an easy solution. I did an experiment: selected the layer the same way, then painted bright orange UNDER the layer. It didn’t stick out. So it cannot be the selection, can it?

I've bad this problem before as well. I dont know why it happens, but it's super annoying

Reflected - maybe Skatezilla can answer this one - I would suspect, that the metallic and non-metallic parts in the 3d model are different bodies, thus enlarging the texture doesn't help. Maybe you should enlarge the texture for metallic part for few pixels and add dialectric texture there. I'm guessing.

..that the metallic and non-metallic parts in the 3d model are different bodies...

 

▲ no, that's one body. one part of hte 3D model

i am pretty sure that's because of the mipmap-ing (mipmap calculations in PS: hard separation, pixel degeneration)

 

try to save the texture without mipmaps in the first round :smilewink: (both: diffuse and roughmet)

Great question Reflected ! Il try your method asap Vampire, thanks mate. All I have been doing is trying to smooth the edges and thinning them, which doesnt really work.
