Did some poly modelling (3ds max) today and got this strange effect when rendering. (most noticeable on the left hand wall). I get this in Studio as well as 3ds Max plugin and still get it if I convert from Edit Poly to Edit Mesh mode in Max.

I'm sure I have seen this before in these forums but a while of searching has brought nothing.

Could anyone help please?

Are the walls quads? you might want to triangulate your mesh, and then soften or harden your normals (in the Object Paramater/Display menu)

Hope this helps

Are you using any bump maps or textures on it? The triangles might not be perfectly planar....Try setting smoothing to flat and press Recalc normals, or simply recalc normals in Studio.

Thanks for the replies.

Brett - The walls are quads. I thought of triangulating (used tesselate) and this made a mess of the mesh. Messing with normals didn't help - I still need to learn more about this side of Studio.

Mihai - I get this problem with the default material but used a texture to make it easier to see. The brick texture I used did have a bump map and when zeroed..... no problem. This is great but too bad if I wanted a bump.


Now I check and even the Studio's default texture has a bump of 30 with no map (image) assigned to the channel.

Thank you very much both for your ideas - I will continue to mess with the bump and see what happens.
