Hi Sukender, My guess is that the problem is not related to the bin management, rather missing vertex colour or vertex normals on some of the geometry. If it's not this then perhaps you have transparency issues. Robert. On Thu, Nov 6, 2008 at 12:34 AM, Sukender [EMAIL PROTECTED] wrote: Hi,

Hi Vincent, The bounding sphere of transform is in the coordinate frame of its parents, the children of transform will be in the transformed coordinate frame. Now you may have several transforms on the go at once, so one can't say that one is local or one is world coordinates unless you know
