I am trying to create a sheet of rusty corrugated iron for a backdrop for a piece I am creating. I have had no luck with the formula object. I tried x=u; y=v; z=sin(u); This does not create a wavy sheet?? I've had a little luck with a squashed rectangle and the linear wave modifier but the performance for screen refresh is terrible (PIII 400Mhz 512Mb). When adding a rust shader the performance of the render is dreadfull Any recommendations? Regards, Andy Clark

why not just draw the "side" view in a vector type program (illustrator, freehand) and then import it and extrude? that will give u the shape, and definitly use a map as opposed to a shader if you want any rendering time at all. If your shader is good, then render it on a flat sheet, export it as a texture (picture) and then map it to the sheet

You can also use Anything Grooves and the Scanlines shader to do corregated steel.

inteats of z=sin(u); try z=sin(36u); remeber it uses radians so piu will give you one cycle of bumps and 10 will get littl3 more less than 12
