:) yes, I mean to collapse the modifier stack so you export pure mesh. You don't need to attach the part together, you can keep them grouped as you did, the only important thing is that all pieces are meshes. Very important too : you must be sure that all pieces are "real", I mean if for exemple you made the spokes as an array, you must be sure that they are copy, not instances or references, otherwise they wont export :(. The materials export without problems, even if you apply many materials to a unique mesh, they will still export perfectly to poser :) For exemple, on the little cube here, each color is a different material on a unique mesh, it would import perfectly in Poser, with all materials assigned
