Hello,
I am having some issues with building light info.
After building the lightmaps a few models I have get strange patterns applied on them :
While it looked like this before building :
I am guessing the pattern is the lightmap texture tilling but I have no idea why and how I can fix this.
Thank you for your help.
PS : I am a programmer I have little to no understanding of the art pipeline, I just hit the Build button
It’s your lightmap uv’s and uv’s. You’ll have to re-do them. Are you using Blender?
Take a look at this thread: https://answers.unrealengine/questions/45196/strange-texture-artifacting.html
- lightmap UVs are overlapping -> recreate it
- make sure that you use the right lightmap coordinate index

Apparently nothing is overlapping so I am looking at the coordinate index, thanks
Then just set it to “1” so that the UE4 is using the right uv for the lightmap -> this will solve your problem

It did solve the issue, I had to tick the “Generate UVs” as well now everything works great
Thanks a lot for your help !
