Hi. There is my project "Dunes". In ZIP included two sets - planar UV and UDIMs. Files format: FBX, OBJ, ZTL In planar set included dislacement map texture. 16K In UDIMs set included 32bit displacement maps and AO maps. 16x4K For my render I used Maya, Renderman and Nuke For color and specular I used PxrFractal (renderman noise)
