if the alignment is really #(*$*%$%$}{\\u]i[i\
like
then its because of the mesh and then there is little you can do
exporting meshes back to max, MIGHT work, but the exporting process is buggy and kind of sux
if you just want smaller scaled rocks, then instead of exporting it and doing it by hand, which would suck, you could use a texscaler material
click New in texture browser, and choose TexScaler
and the rest will be logical i think
