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"

Shadows from static objects are low quality.

alt text

As you can see, shadows from objects set to Static are noticeably lower quality than others. I was trying to tweak lighting settings here and there, but with no result to improve that.

Here are my lighting settings on the light source and in World Settings: alt text

Also, lightmap resolution is fine: alt text

If anyone will give me an advice about what could be done here, I will be very grateful!

i'll post this as comment and not as answer cause i'm not really sure about the issue. Telling us if you light source is either static/stationary/movable will help. Btw this is something that usually has to do with Bias

The light source is stationary. With movable I can control shadow quality with cascade shadows - that is I know.

Quality of shadows from static objects depends on light map resolution of object's that receives the shadow. Such small and detailed objects would be often better with dynamic shadows. Despite your statement, that lightmap resolution is fine, it is not fine enough to get the shadow you want.

So, don't use small objects as static then? That is the whole problem?

Either that, or simply accept the quality, or crank up lightmap resolution, if case permits.

i would suggest to actually remove shadow from the majority of the meshes in the world, but i guess that's a game design decision. Small meshes are gonna cast small shadows, if it's a weapon make it movable, if it's a piece of prop on the ground you can remove it. player is never gonna care about such small shadows, infact a huge slice of the PC players just disables shadowing. That's my opinion i'm not saying i'm 100% right =P

It's not so much about game design, I was just trying to play around with lighting and see what I can achieve. Shadows from static objects seem to be pretty bad. I enabled and tweaked Distant Field Soft Shadows though, and it gives substantially better results. Although the downside of it is that I have to manually go through meshes and set distant field shadow resolution on each of them and check if everything looks good in mesh distant field visualization mode.
