Mesh smoothing bug?

Recommended Posts

I tried to render a quite complex mesh, converted from a terrain model to be able to apply an image texture to it. Everything worked fine until I turned mesh smoothing on in the document settings. Then the mesh turned black. So I did some experimenting and found out that a smoothed mesh with an image texture will not receive light other than ambient light. If I use a procedural texture it will render fine and smooth. There also seems to be a connection between the size of the mesh and the result you get. You never get a smooth mesh with image texture, it?s alway edgy and full of artifacts, when the size of the mesh (number of triangles) increases, larger parts gets black. This looks like a bug to me, but is there a way around it in the current version? I really see a potential for higher realism in rendering architectural models with this feature!

It's also briefly described on the VW12 Upgrade Companion CD on page 107 of the PDF:

New 3D Power Pack Capabilities>Create Draped Surfaces

The movie download shows the procedure.
