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"

Self Shadow in realtime?

Hello! :)

I'm working on a project. Actually it's just to render a character. So I was playing with the lights to see what I can do.

I have this result with a spot light :

It's not that bad, but the cast shadow is kinda wierd. The shadow should be more something like that (done in photoshop) :

The question is : Is there something I missed to render a better realtime self/cast shadow or should I have to bake a lightmap on my mesh?

Hi MathieuSP,

When it comes to very small areas of the mesh like nostrils you can lower the Shadow Bias to create more accurate shadows. The lower the number the closer the shadows will generate relative to the caster surface. Here is a before and after pic of default Shadow Bias vs Shadow Bias = .02

You can also increase the value of contact shadow length however, the results don't look quite as good up close in the characters face.

Let me know if that helps,

Ed Burgess
