Wing-mounted sci fi gun

My first experimentations with Substance Painter. Some of the textures arent great, as a beginner it was a little hit and miss moving sliders, experimenting with layers, masks, learning the UI and reverse engineering other smart materials. The black block in the middle was what I textured last, so that material with the worn edges, roughness grunge and the smooth transistion into the silver cylinder is probably the best part. Also going with 3 texture sets that were 4k each might have been a bit overkill. I also dont think I optimised the UV space as much as I could have, but oh well...
