Hello. I have some huge objects in Maya (poly) that I want to scale down and after that to transform the vertices by multiplying with the transformation matrix so when I export the object I would not have to export the transformation matrix but only the vertices changed according to scaling.

I want this is because in my game I place those objects interactively and I don't use the transformation matrix from maya scene and I don't want to use it just to scale down the object.

Is any way to do that in Maya in a simple way or I have to aces every vertex and transform it ?

Not sure about maya, but in max (also autodesk :)) you can do a Xform transformation and scale the full object (all vertices at once). That way the exported mesh/ vertices are scaled and/ transformed as you wish.
