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"

Masking post process effects

I was thinking of making an effect where the game environment is black and white, but the player's are in full color. Is there some sort of way of masking tonemapping for objects with specific materials?

I think this should be easy: You can use the stencil buffer (for that, I think you must set "Custom Depth-Stencil Pass" to "Enabled with Stencil" in Project Settings>Engine>Rendering>Postprocessing) and enable custom depth on the player mesh, then setting the stencil value (set it to something greater than 0 just in case; keep reading for details) so you can make a postprocessing material that looks for pixels with the stencil value you put on the mesh (I am not sure it will work if you set that value to 0), and colors those normally, while making everything else black or white,as you said.
