Hi Andy!
I Don t know how the engine programmer use for the model the collada format,
there are many other better also, AC3D for example!
However if export the collada model, then import it in visual3d or s2engine
the model is not to see, i will take a experiment as you say compare the file from milkshape and AC3d, i will send you both then you could look yourself.
Thanks for the answer !
regards
