I have a problem with small (0.02m radius) spheres in GMax.The attached picture shows transparent areas in the grey sphere in my model. As a test I added another sphere in pink. This is orientated differently with the transparent area just visible at the bottom. These areas seem to appear at the 'poles' of the sphere. They look ok in GMax and only appear in FS.Large spheres are OKAny ideas???

The vertices at the "polar ends" are simply too close together and are being auto-welded by the sim.Use the "Geosphere" instead of "Sphere" to avoid this problem. The "Geosphere" doesn't have "polar ends" but instead has all the vertices spaced equally around the entire surface.

Thanks. I'll try that

Yes, it workedThanks
