Well.. what i meant is that retail like is the 'type 0' with a texture that is spread all over the beam. The standard retail type beam is exactly as having of +Tile Factor: 1, 0. As for the type 2... well.. The tables in the beta mediavps, the beam sections of them that is, are AFAIK from bobboau and they are actually build for the changes he had made in his own version of the FreeSpace Open code. Like having more than 5 beam sections etc.
Also ATM code doesnt seem to have support for other two types. Either the one which is triggered by using 1 in the tiling type or by using anything else.. The second option triggers the 'type 0' tiling type.
