Question by raminsh · Jan 10, 2011 at 12:03 AM · meshrenderingobjectsoverlapping

Overlapping meshes create weird rendering problem

Hello I am sure that people have asked this before but I can not manage finding any of those questions similar to the issue I am having now. the problem is I am using some really low polygone models for buildings and what not and in these models there are some meshes that are inside eachother or have overlapping surfaces which they look like these images I have attached. does anyone have any solution for this problem? alt text I must add that I did try fixing this by changing the numbers in near clip and far clip of the camera

Looks like z-fighting. The solution, more or less, is not to have overlapping coplanar triangles. (There are other things you can do, but in general, overlapping geometry of that sort should be avoided, at least when it's likely to cause rendering artifacts.)
