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"

With the information provided, this is not enough to proceed.

This really only looks like it could be one of the following:

  • Low lightmap resolution

  • Poor UV Lightmap layout: UV islands get too low of a resolution, even with a large lightmap

  • Shading differences between actors with static indirect lighting, which is a limitation of the current implementation of lightmass.

To continue investigation the following information is needed::

  • Needs to be reproducible. Are you able to reproduce this in a blank project or only with your level/project/assets?

  • Screenshot of Lightmap Density View (ViewMode > Optimizations > Lightmap Density)

  • Screenshot of UV Layout of the most offending assets like the curved desks

  • Specific light settings used

Thank you!

If you provide the other information I requested I'll have much more to work from and offer some suggestions.
