I created a video with a quick overview of the texturing and lookdev work I did on the Bell OH-58 Kiowa that I recently published. All the work was done in Substance Painter, mainly with Tiled maps and Tri Planar Projections (for decals and grunge spanning over multiple UDIMs). I spent a lot of time hand painting the imperfections on the panels, tension and cushion effect where the rivets are. Plus a lot of weathering effects, tweaked UDIM by UDIM to achieve the desired look on each part of the helicopter.
I'll discuss the entire process in details in a 2 days workshop in Turin, Italy, Saturday 8 and Sunday 9 June 2019. Here is the link if you want to attend!

I also posted of images that show the different maps (Albedo, Metalness, Roughness, Normal, Bump, Opacity) used to obtain the final renders, plus a Shaded render and UV Checker, to show the scale of the UV.Total UDIM count is 22: 10 for the ext
