Say I have an object that needs to be rotated SetObjectRotation(ID, 90, 25, 180).

How can I adjust the objects vertices in a memblock to reflect these changes?

I am combining multiple objects into one mesh, so rotating the final mesh won't work.

Thanks for any help!

So create the object as stand alone at 0/0/0 (When you first create the mesh)
Then rotate that separate object, record the change in x/y/z of each vertex
Then apply the change to each vertex in the mesh

Right, but I don't know how to apply the change. No idea how to rotate the vertices correctly, or "record the change per vertex." Only the original vertex position is recorded in the memblock, AFAIK. Unless, there is a command that will set the rotation permanently, like we can do with setobjectscalepermanent(). I am not aware of one.

Maybe I am misunderstanding?

FixObjectPivot() works like SetObjectScalePermanent() except for Rot & Pos instead of scale.

Thanks, Blink0k. I wouldn't have thought to look for that.
