Hi Kelvin, Yes it is v1.3 that I am using. Am I right in saying that if an object is loaded in and is translated to say -10, 1, -48, that object still has its own local coordinate system? So if I want to attach a bounding leaf as a bounding sphere I must set the centre of the sphere at 0, 0, 0 or some coordinate near to that. Also, when I tried to load in some files with texture maps, they appeared in the scene as a plain greyish colour. Is this because the loader cannot get at the geometry needed to texture map because of the type of file used, or would it be the NCSA loader that does not support the texture maping?
