Hello, I am currently having issues regarding developing a lightmap in Blender for UE4. At first I had the issue where I would build the lighting and the object would go black and discovered I need to make a lightmap. I have followed many tutorials on how to do so and did a lot of researching on my issue with no luck. Currently, I have a lightmap made and looks correct based on what I have found for tutorials and when I go to build my lighting, it still says I have UV overlapping, even though I certainly do not have any overlapping in the UV. Here are the pictures of my approach and result:
Any help will be appreciated.
