yes, for Collada and 3DS importers. obj has some support, but i think as you have found, the material assignment still needs a little work > Has any progress been done in tracking down the memory leak in > away3d? got a little present for you paullaster - the trunk has been updated to version 2.2.7 with a substantial overhaul of (some) of the object creation routines. We have two new classes in core.utils, CameraVarsStore and DrawPrimitiveStore. These use object pooling to reduce memory leaks - would be interested to find out how they fair with your projects that are having memory leak problems, and anyone else who is having problems in this area cheers Rob On Thu, Jan 15, 2009 at 11:13 PM, Fabrice <[email protected]> wrote: > @ben*Are hierarchical models supported for any of the geometry importers > in Away3D?
