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"

Using vertex color in post processing?

From what I can see using the material editor, vertex color is not an available option in scene texture nodes. I'm assuming that means vertex color is not available in the g-buffer.

Is there a way to add vertex color to the g-buffer, or somehow pass vertex color to post processing, as a scene texture or in some other manner, without using channels like base Color?

This is possible, but you have to modify the engine source for the GBuffer to get vertex color info. This guy did it here, but didn't give any info on how he did it (other than saying he used the alpha channel to pass it):
