Help with bump maps
Hi, im having a problem with bump mapping. I did a spline object, which i placed inside extrude nurbs, and now i applied a material that has a bump map enabled. But i cant see the bump map in rendering.

what is the Projection of the texture? Any scale difference (LengthX, Y)?

Im not sure what you mean by the projection, but the bump texture is a JPG image with 512 x 512 resolution, i have tried different sizes like 2048 x 2048 and 1024 x 1024 and 256 x 256, but they only change the shading a bit. But for primitives, the bump map can be seen very clearly. I have also tried to change the Extrude nurbs type to quadrangles with regular grid checked, but no change.

Projection refers to the setting in the material’s texture tag that tells Cinema how the material should be wrapped around your object.
If it doesn’t render on the caps, try adding the material a second time (two texture tags), and in the second tag’s “selection” box, type: “C1”. That will tell Cinema to place that material only on the first cap of the extrude. The other built-in selection sets are C2 (end cap) and R1 and R2 (rounding/bevel 1 and rounding/bevel 2).
Projection for the caps material should be set to “Flat”, and you may need to adjust the rotation with the texture axis tool.

Thanks for your help, i changed the projection to flat, and it worked 🙂
