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"

Custom Depth Pass Doesn't Effect Post Processing

I am trying to use an object which doesn't render on the main pass but which renders on the custom depth pass. I want to read depth in to the buffer so that the depth of field post processing effect doesn't effect the area occluded by the mesh.

The mesh is supposed to be a double for a translucent mesh which I want to see through clearly even though the rest of the background is blurred by DoF. I created the duplicate mesh on the custom depth pass thinking it would simply read to the depth buffer and prevent the DoF blur from happening but that isn't the case.

If anyone can explain to me why this isn't working (my guess is that there isn't any easy way to fix this) that would be awesome. I've been pulling my hair out for days over this.

The image below shows the outline of the custom depth duplicate (and it has an opaque material applied) next to the wine glass which I would like to double it over. Notice the brick in the distance is still blurry even though the settings on the right would indicate that it is reading into the depth buffer.

Bump. I'm having the same exact issue.
