Hello. I have 2 materials in the same mesh each one asigned to the faces in it's own uv channel, so 2 materials for 2 UV channels BUT the first UV channel material renders ok while the 2nd Uv channel material renders black (nothing at all). What am I doing wrong?
have you linked the 2nd material to the 2nd uv set? You can do this by CTRL+Rightclick in the viewport then choose UVSets-->UV linking Then select your mesh,it will show the mesh with its uv sets below it on the left pane,select your 2nd uv set,then on the right select the material you want to link it to,double check that…
