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 do I get better shadows on my meshes?

Hi. I'm having issues with how the Stationary light's shadows produced by static meshes are coming out. They appear to be highly inaccurate for some reason.

This is how they look with default settings

Increasing the lightmap resolution of the floor and the meshes seem to make things worse, as the shadows simply disappear.

This only happens after I build the lighting. The shadows look fine if I move the objects and don't click Build. Like this.

They also look fine in movable meshes. Movable lights also show the shadows correctly, and the issue is present in all the types of lights, point, directional or spotlight.

I've tried everything, even recompiling the entire engine, with no success. I've also made sure that lighting quality is set to production and scalability settings on Epic. Could this be an issue with my computer?

Thanks in advance

Are the floor and wall meshes BSP?

Yes! Do they all need to be static meshes perhaps?

Nope, BSP works the other way around. The lower the resolution, the higher the quality. Just lower the resolution and it should be fine.

I lowered the lightmap resolution from 32 to 16 and it is displaying them much better :D

Thank you! I will keep playing with it and see if I can get smoother shadows as well :)
