My UV maps are overlapping 50%. Every fix I have seen for this says to generate an additional UV map but it looks like it already has been generated and is not overlapping. Any ideas?

Ignore the brick texture on the back wall please

The answer is in other channels. This was happening to me before. Check the option to display Channel 2 or even Channel 3 and you’ll probably find out that the UVs indeed overlap.
Report back with the results and I’ll help you for sure. It’s not a big issue. :slight_smile:

Thanks for the quick response! I am kind of new to the program so I guess I am not quite sure how to do that? I am clicking on the UV menu and it looks like there is only a channel 0 and a channel 1. Also, I forgot to mention that I made the object in Blender so I am not sure if that might affect it?

Step 1:
Select and Delete any UV Channel that isn’t Channel 0.

Step 2:
Check ‘Generate Lightmap UVs’ check-box.

This should fix it. :slight_smile:

P.S. If you are willing to learn more about the Unreal Engine 4, I might be able to offer you mentoring.
Let me know if you are interested and let me know if my answer helped you fix the problem.
