Oxygen 2 - Manual
As far as I can determine the maximum number of characters one may have for a texture name (and probably a material name)is 64 characters. Up from the 32 characters in OFP. By texture name i mean the fully qualified ArmA pathname + Texture filename.
If someone else could confirm this then it can be added to the manual. --Sy 06:20, 25 September 2007 (CEST)
