My lightmap is completly black! What am I doing wrong?
1. Are you using VRay renderer? If yes than get sure if you’re using VRayMtl as materials. You can use “Batch convert materials” button for this 2. Try using Utilities -> XFrom and Normals modifier to flip the normals and then render again. 3. Look at renderer debug window, it may come handle My shadow is not correctly aligned to the edges There could be two reasons. 1. You’re trying to pack to much objects onto too small lightmap. Try adding another lightmap and moving the objects there, or increasing the resolution 2. Your unwrapped UV elements may be too close to each other. See lightmap UVs tutorial by Stephen Jameson Similar, but different problem is the one below All my shadows seem to be offseted/biased! Go to your lights in 3dsmax and try to set shadow bias option to 0 (or at least close to it) I’ve been lightmapping succesfully for a while, but after I’ve edited a little my mesh I get “Unknown system exception” Of course this exception doesn’t precise exacly what happend, but
