Thanks Jason, changes built fine and are now checked into svn/trunk. Merging these changes reminded me of the scaling problem, and that the old Quake plugin had the same problem originally, but I vaguely recall fixing this. So I've just done a review of the old quake3 bsp code and found a hacky fix for the scaling in Q3BSPReader::convertFromBSP(..). This hack hardwires the scaling to 0.03.
Could it be that the Q3 models are scaled in inches rather than metres? Could it be that the Valve models have the same scale? My inclination is to pull the hacky code out of the the Q3 codepath and place an optional static MatrixTransform above the whole scene graph for both the Valve and the Q3 paths. I the mdl and md2 plugins would probably also need such a transform too. We could standardise of a ReaderWriter::Option string that enables/disables this scaling across all the plugins to keep things consistent. Thoughts? Robert.
