Does the collada converter support mirrored geometry from 3dsMax. In 3dsMax these are done with negative scaling. In my own tools I detect that and make a mirrored copy of the geometry. |

No that's currently not supported. |

I'm going to add it, any hints as to where would be the best place to hook it in? Go through instances early in Converter::convertModel() to duplicate-and-mirror meshes that are referenced by instances with a mirrored matrix? |

That would be great,... I can't tell you exactly where to start, maybe arount line 500 in the converter.cpp, but you have to make sure that at the end you have a positive scale and a correct tangent space basis. |

By the way, for this function: Code: SceneNode *Converter::processNode( ColladaDocument &doc, DaeNode &node, SceneNode *parentNode, Matrix4f transAccum, vector< Matrix4f > animTransAccum ) do you mean to pass a copy of the animTransAccum vector or a reference? |

No it has to be a copy, since the method is called recursivly and the child nodes are not allowed to overwrite the vector. |
