> well since i think TS normals format has only 6 o'clock directions and you are assuming 8 then you are going to get some indexes repeated. besides, with more possible angles in the ra2 format, the angles available are closer to the ones you want.

We can provide a TS normals lookup and an RA2 normals lookup file. Easy that. But I think that, for now, TS is the easiest to find.

Looking for the right RA2 normals is more difficult because there are more possible choices. For TS normals, it is often obvious which corresponds clearly to a certain facing.

Besides, isn't 3x3x3 = 36 significant to TS normals?
