Hello everyone, I’ve encountered problem I can’t find explanation for. As You can see in the attached file the faces of the object are rendered in strange order - so the face that is behind is drawn in front of the face that should cover it. Model is imported from blender and everything looks ok there. Please, If anyone here have any clue what’s causing the problem give me a hint - so far I tried many ways to get rid of this without success. But I’m newb. I’m staring at it baffled, as it happens only on that one particular mesh.

hard to see on pict if you do not experience it… but first Q, would be: how big is this model, or better said, how small is it? Blender works at very small sizes. For the sake of test, can you scale up the model for a fair amount to see if it still occurs?

Thank you Fabrice for the answer - I was so sure that there must be something wrong with my mesh, but it turned out to be the alpha blending and z-sorting problem, as I read on the forums. Alpha treshold is the way to go for me right now, as those alpha blended meshes in my project are very long trails of road signs etc. and their pivots will always mess up with the sorting.
