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"

How to prevent depth of field "bleed"?

Hi All

Is it possible to prevent depth of field "bleed" as you can see in this picture; alt text

The far transition region is about 300cm beyond the point of focus- the character's chest. It doesnt matter if it's 1000- the only point at which the bleed stops is when the scenery behind it is in focus (or if its darker). Obviously, if it was a real camera, that wouldnt happen- the edges would be sharp as long as the far transition region was beyond the edge.

Thanks!!

Hey robbiecooper -

Can you let me know what your full DOF settings are? In particular I am wondering what your Focal Distance and Focal Region settings are at?

Thank You

Hi Eric

This is the blueprint set up; alt text

The near transition region is set at 200 less than the last point of focus, the far transition region is set at 300 more than the last point of focus. The point of focus is the result of a capsule trace from the camera, at the center of the screen. I've tried different settings, extending both near and far transition regions, using the current point of focus etc.

Thanks for the reply!

Hi Eric, is this effect due to screen space reflections or something?

Hi Eric, if I reduce Bokeh size, the double image/bleed is correspondingly smaller. Seems like there should be some logic in the engine to determine where edges are and if they are within the transition region?
