Irrlicht Engine

in ISkinnedMesh SPositionKey,SScaleKey and SRotationKey instead Matrix operate,and omit SScaleKey in irr, i think this is the ugly idea,because there some error when assemble matrix with SPositionKey,SScaleKey and SRotationKey ,so some translation have been killed. i hope it will favor matrix ...

why annotate SScaleKey in CXMeshFileLoader::parseDataObjectAnimationKey ,i have some error with the model load,the some mesh is wrong in scale or rotation,

have you happend some error in CXMeshFileLoader? and how did you deal with it?
