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"

Wavy shadows on bottom edges of meshes

I have dealt with this issue in the past, but the solution I used to suggest no longer works. I had to reformat between 4.16 and 4.17 so I don't know if it was something altered or if I am simply missing something.

alt text

The half-capsule has smoothing, the cubes do not. Some cubes use per-facet mapping, others use various of the auto UV options in Maya. The result is the same at every shadow quality level, and in high, ultra, and cinematic engine settings (I haven't bothered with lower)

How are others removing the shadow-warp?

Did you tried to disable Ambient Occlusion? Just to test it?

I hadn't, but I have now, it didn't resolve the issue.

I'd say it's a lightmap problem... can you show us the lightmap uvs? ...and what is the resolution you're using? Are the meshes intersect with the plain or snapped on top of it?
