So i’ve a bug where I’ll be applying materials to objects, and they will render fine in that project. When i link it into another one thought some specific things either render pure black, or default to their render appearance settings. I’ve remade the geometry and tested the materials on that, remade the materials etc. but no luck
Can you please make sure that you have corresponding materials in both projects? E.g. if you have Bricks material in Project-1, make sure Bricks material exists in Project-2 as well. Thus, after you link Project-1 into Project-2, you can play with the appearance of linked materials, assign them with V-Ray materials etc.
If this is not your case, please let us know and provide more details. If an error messages pops up, attach is as well.
