How do you convert .DAE (Collada) files back to .rigid_model_v2?

[RyansPlace]

When modding 3d files, I use RMV2Converter to change files from the .rigid_model_v2 to .DAE (Collada) file format readable in Blender. After editing, how do I convert a .DAE file back to .rigid_model_v2? RMV2Converter only works one way.

Also, could you advice on aligning a model to fit a texture:
