A lot of objects are able to be mirrored one way or another (are symmetrical on one or more axis)
I thought a mirror function would be extremely useful for reducing load times and model media footprint size if you could load half a model, clone and mirror it.

Loving the mesh functions !

not a boom! in most cases the indexes need flipping also since your basically making it insideout by assigning a negative scale factor. This will work if you have your cull draw mode set to 0 but normally backfaces are not drawn to increase performance. I would also imagine that the normal will be backwards also reflecting light incorrectly.

I would use external software to actually flip it as it will correct the light reflection and eliminate needing to draw backfaces.

I just noticed there's a bunch of memblock commands for meshes. This will be something worth exploring and could be used for this purpose I think?
