I toyed with LuxRender a few years back, in the 1.3 era, and well, Lux has moved forward a lot since then. Trying to get back into gear, I was trying to take these metal textures https://www.reddit.com/r/blender/commen ... _comments/ and use them in LuxCore. Each texture pack has 5 files:
- NAME_color.tif
- NAME_height.exr
- NAME_metalness.tif
- NAME_normal.tif
- NAME_roughness.tif
Disclaimer: I'm not the creator of those materials, I just found them while browsing around, so I can't attest for their actual quality beyond what the previews show and how they work in Cycles
