Corona Bitmap and 3ds Max bitmap scale UV tiling from the center of the texture space while the UVW Xform modifier scales UV tiling from left to right.
This feels like a typical development oversight from Autodesk, but I'm wondering if there is a way to align the functionality of these two (three) implementations(?)
Right now, the only way to replicate the UVW Xform modifier in the mapping settings of a Corona Bitmap is to offset the UV tiles, but this can get really complicated for arbitrary offsets.
