UV bump map oddities?...

Hello Softimage Gurus,

Ok I am trying to uv map a simple bump onto a shape (only rough at teh moment trying to get it to work) but the bump map doesn't hit the sides of the object even though I have mapped it to the edge and drawn the texture over the edges!...

I have attached a couple of photos explaining what is happening... Why doesnt the bump reach the edges of the shape when rendered? This happens whether the mesh is subdivided or not.

Show us a screenshot of the render tree, please. Bump mapping isn't straight forward, and we may be able to help seeing the render tree.

Ahh ok the problem was using the bump map as opposed to bump map generator as a node. Not sure what the difference is but and open GL look identical, but rendered behaviour is completely different!

Right, I suspected the problem was in the tree. Bump map generator is the one to use. I'm glad you resolved it.
