I have models that I used custom lightmap uv for to get better results and these models get a bad lightmap like displayed below in the picture. How can I fix this? I tried Recompute tangent and Recompute normals, it didn’t change anything. My uvs look like the second image
Try bumping up the lightmap resolution (bottom right of your 2nd picture), it’s currently at 64 which is a bit low. Try using 256 or 512.
Fixed it. My uvs were corrupt when I copied from the software I used.
