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:



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.
