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"

Lights cast texture as shadow

Is it possible to make a texture become another when a shadow from a certain object covers it (such as characters, furniture, and items).

I am essentially trying to mimic the shadows from the game, 'Wolf Among Us'.

I don't think it's doable out of the box, you can try to use a decal:

You can also consider drawing to render targets:

Or maybe do a post process effect material that will let replace any black in the image with another image.
