When I try to export a model with animation, in some cases it works but in others max crashes. With debugging I found that in my case it crashes with a stack overflow error inside the function:
XMLNodePtr ColladaExporter::AddHelperNode(XMLNodePtr& maxExtraNode, IGameNode* sceneNode, IGameObject* helperObject)
at the line
simpleObject->GetLocalBoundBox(TIME_NegInfinity, sceneNode->GetMaxNode(), NULL, boundingBox);
I am not sure if the stack overflow happens only there or can happen anywhere depending on the data. I commented out the part that exports <extra> nodes for helper nodes and it worked. Not a big problem since I don’t need the <extra> information. Thought it might help finding a bug.
