Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

How could I fix wrapping UVs error?

Hi, everyone. I'm having a problem when I convert a BSP object into a static mesh. In fact, when I build the level, it gives me the "Object has wrapping UVs" error. [img 1] The object I made is this: (is it a problem if there are two overlapping BSPs?) [img 2] I've also tried to set the lightmap index to 1 but nothing changed. Here are UV channels 0 and 1: [imgs 3 and 4] Could you help me? P.S. sorry for my bad english

Update: https://youtu.be/z5yc-bKbHyc I've used this tutorial and now there aren't errors but there are some light bugs. Do someone know how I can fix them? alt text

Occasionally I get problems like that when my lightmap resolution is too small, though that may not be your problem.

To test, try increasing your 'Min Lightmap Resolution' to 128 or 256 and then 'Apply Changes'. If this doesn't fix it, then feel free to set it back to 64.

When it isn't a matter of the resolution being to small, I typically do a more complex unwrapping of my mesh in 3DsMax and that fixes it. Though I am not familiar enough with BSP objects to know if you can do that.

Thanks a lot for the answer. I'm going to try it tomorrow and tell you if it works.

Ok, I've tried this but, unfortunally, it seems that nothing changed.alt text

The UV 0 is still strange.
