Advanced Question Texture bleed over

[Interceptor]

HI,I recently finished texturing my Mars base,and noticed that one of my buildings has a couple of texture bleed overs,what I mean by bleed over is that there are some wierd flickering in the texture, check the pics out .How do I go about fixing this problem?Thanks

Z-fighting. Avoid two surfaces overlapping in the same plane or in parallel planes close to each other.

Z-fighting is more severe for low-resolution z-buffers and at large distances. So for best results on all target platforms, always test your meshes in a 16-bit frame buffer over all distances at which the mesh is visible.

In custom meshes (which yours don't seem to be) Orbiter supports the "ZBIAS" flag in mesh groups to resolve z-fighting issues, but this should be used with caution. Z-biasing is a somewhat hacky DirectX feature which can itself lead to visual artefacts (more distant z-biased surfaces covering closer unbiased surfaces)

z bias flag ??

I'll try to understand that more precisely some day but in the meantime, searching on the web about, i found something in the chapter 15 ( about meshes in Direct X ) and a lot of informations that are a zillion of feet upper my head but that could be interesting for others.
