View Full Version : strange rendering problems

03-23-2011, 09:47 AM
I have been having this problem for awhile now. When I render a scene that is 720p or 1080p some of the frames will have these horizontal areas that are brighter than the rest of the frame. If anyone knows why this is happening I would greatly appreciate it.

When your renders are running do they render in a distinct segment at a time? I.e. does it do the top bit, then the bit below? If so your segment memory limit might be too low, and it's splitting the frame up. If you have things like radiosity it can cause seams..

Go to the render tab > render globals > general tab > segment memory limit... Set it to a larger number like 128 meg, or whatever it needs to be.

If it's not that, I am not sure? :)

You can also try rendering with just one thread. Some shaders can cause these lines...
and what tobian says.

Using just one thread seems to be working. Thanks!
