Situation: I wanted to render a scene which is made up of a few flowers model in the foreground, and in the background, I have a grass particle system.
Problem: Whenever I tried to render, there seems to be a bug which looks like the image below. It's as if a part of the grass is displayed over the flowers, which should've been in the background. How do I fix this?
After trying over, I found that one solution is to turn off 'strand render' under render settings on the particle system of the grass. That way, I wouldn't see those overlaying grass effect. However, when I turn it off, I would have a different result for my grass and it doesn't look good at all. Here is my Blend file: http://www.pasteall.org/blend/30319
Well, my blend file is too big to be uploaded so I deleted some settings and objects in order to have as minimum size as possible. I used just a plane on the blend file above. but as you can see the problem still applies. When we render, there are a few traces of grass over the plane.
