How can I force Unity to use my UV2 channel for lightmapping?

Hi @jinda_1

It seems like in your DCC package (your external 3D app), you’re not assigning it to correct channel, therefore Unity reads from the correct channel but incorrect data. For instance, there’s a way to check UV layouts in your UV channels in Maya through a Python script, I shared some details here: Progressive CPU Lightmapper page-6#post-3151080 You can check that post.

Thanks
