    For same scene, I baked lightmap on Windows. new lightmap generated. Save the scene and the scene (.unity3d file)has no changes.
    When I open the same scene on Mac, the texture coordination is totally messed. It works well until I re-bake the lightmap, after re-baking, lightmap has also changed, but this new lightmap displays not correctly on Windows.

    In this whole process, the scene has no changes.

    Anyone meet the same problem?

    Now this sounds weird... could be because of OpenGL/DirectX rendering differences!

    Could also be the Mac stuffing things up. I otherwise wouldn't know. Are you using automatic UV generation?

    Hi - there are some known issues transferring baked lightmaps between versions, re-baking on the target platform should work fine and is the current work around for this, please bear with us while this is fixed.

    This is quite a problem for us, we're primarily using Windows in the studio and our lightmaps are baked on a Windows machine, but this issue crops up for those of us using Macs. I don't want to have to rebake our lightmaps every time a change is made so a fix will be greatly appreciated.

    Hi, we have the same issue. I wonder if there is already a bug reported and can be tracked in the issue tracker, or we can help to file one.

    Try bake lightmaps on PC, when editor forced to use opengl. In this way lightmaps seems work fine on Mac.

    Just voted. :) Hopefully, it get's fixed. I might as well give that new openGL pipeline a go, speaking of which, maybe that won't freeze for me... :D

    Hello,

    it seems that this is still an issue with Unity 2017.3.0p2. Can anyone confirm?

    At least, baking lightmaps on Windows, then making an AssetBundle on Mac for that scene, and using that AssetBundle either on Mac or Windows does not seem to show the lightmap correctly.

    Why am I doing it like this? Well, studio workflow. Artists use Windows, but build automation is on top of Mac / Linux.
