OpenGL ES 1/2 Jagged edges issue

Hey guys

Really hope someone can help me with the issue I’m having…

The model I curently have has polygons in certain places laying underneith other polygons, and OpenGL ES doesn’t know how to handle these when rendering at certain distance from the model.

Seams like it’s confused on which polygon to render infront…

Does anyone have a solution to this without having to edit the model?

Please help!
Thanks in advance

If that happens on some android devices, use bigger near clipping plane value.
