@RomBinDaHouse: Thanks for the issue with the channels,it was a problem with the geometry of the highpoly bolts. I just rebaked em. Concerning padding: There actually is, i just have hidden the layer to better show the layout
@Saidin311: Comes down to a uv layout that is as distortion free as possible and a clean bake of the highpoly mesh. As already stated, every plate and all of the rivets were modeled. I´m going to post some screens of the highres when i do the new renders.
@gauss: thanks for that, i´m going to try to fix the specmap and the reflection in order to tweak it. Concerning texture resolution: I wanted all detail of the highpoly to show up in the normal map so i chose 2048. Would be no problem though to scale it down... I´m going to do some more renders and post the flats after…
