thanks to your reply,what's the version of 3dsmax you use?

3ds max 8

Do you have a texture on the cylinder? Try putting a UVW Map modifier on it, sometimes textured meshes disappear in the oFusion window if they don't have the right uvw coords.

It seems ofusion not working with my 3dsmax7.1, I changed to 3dsmax5.1 and working now:lol:
