Light maps corrupted only in my installation of Unity

Unity Engine
1

When I load our scene, my light maps uvs are are all wrong. However, everyone else on my team doesn’t have this problem. I’ve removed all my unversioned files and reverted everything back to what is in SVN, but I still have the problem.

If I look at one of the objects that is light mapped incorrectly, all the settings in the Lightmapping window are identical with my teammate’s whose object appears fine. So, if we have the same .exr and .exr.meta files, and our settings are the same . . . where is the missing piece that’s different?

I was talking with friends from a nearby company also using Unity, and he said he was having the same problem. His whole team has no problem, but when he loads the scenes it looks like the light map is all over the place.

Has anyone seen this before? Know what’s causing it? Have any suggestions of what I should try to fix it?

most likely you hit the case of difference of auto-generated uvs across mac/win [like you have baked maps on mac then open on win and reimport meshes/regenerate lightmap uv and they are different]
For now the options available are:

  1. use one os for baking/final build
  2. create a script that will generate uv2 once and stores it
    but in any case fill bug report with repro model (the one that gives differences]. And try 3.4 if you didnt already - some stuff was fixed there
