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"

No shadow with world position offset + unlit

I have an unlit material using world position offset that casts no shadow when it should cast one. I have shadows with unlit without WPO, lit with WPO, but not with unlit+WPO.

Unlit materials by definition do not interact with light, so they don't cast shadows. However you can usually get what you want by using a lit material, setting BaseColor and Specular to 0, then just keep your EmissiveColor input.

As I said in the question, I have shadows with unlit materials. The shadows disappear when I use World Position Offset. ![alt text][1]
