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"

Render Custom Depth on Particle System (Post Process)


I'm trying to create an "eagle vision" like in Assasin's Creed : everything except particle systems are desaturated. I'm using a Post process with a blendable Material. In blueprint I connected the particle system to "set render custom depth". I set the material as follow :alt text

But the particle system doesn't seems to work with "render custom depth". How can I desaturate everything except the particule system ? Can you help me ?


[Edit] As you can see the post process works with the mesh but not with the particles

normal vision : alt text particle system custom depth vision alt text mesh custom depth vision alt text

I found an other way to show the particles in color : I set my desaturating blendable material (in the post process) "Blendable location" to "Before Translucency". alt text
