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"

Specific post process color filters?

Is there a way to make my game almost completely desaturated, but still have red objects in full color? I'm not sure how to go about doing that.

I think you could do this through materials.

Set up a Material Parameter collection. Add a scalar parameter called "Saturation". Then you can reference that parameter in any of your materials. Add a desaturate node to your materials and plug your diffuse into it and then the saturation parameter into fraction. Add this to all of your materials except for the ones that are suppose to be red. I suppose you could also make certain parts of your texture red or desaturated using masks.

You can also put all the desaturation stuff into a material function and just reference it easily from any material so your don't have to keep adding the nodes manually every time but its only 2 extra nodes so it shouldn't be too much of a hassle.

I hope this helps.
