I have been trying to make some customised clothing, in Carrara, by joining a Poser 4 body part to a pre-made vertex object. Boolean addition (union) doesn't seem to be very effective. When I do it in the modelling room it always causes a rendering failure. When I do it in the assembly room, the results are strange. There is a single object (which appears to be a single mesh) but when I look closely, I see that it is two meshes intermingled. Is it possible to produce a single continuous mesh from these two? When I try the same process with a simple sphere and cube, it works perfectly. The result is not a mesh of a cube intersecting with the mesh of a sphere, but a single mesh of a cube sticking out of a sphere. Why won't it work with my two objects? Any comments/suggestions will be welcome. IsaacNewton. PS. My system is Pentium II 400 MHz, 128 MB RAM, Win 98
