• flow's polygon import pretty much sucks.
• Only simple, 3 sided RM polygons are recognized.
• Originally, all I wanted to do was bring in models from Font3D, and for this purpose, it is sufficient. flow can also read RIB output from AC3D (although all transform information is ignored).
• After importing a RIB model from AC3D, invert the X axis of it's normals
• There is some funkiness with coordinate systems between Font3D and AC3D - rather than try to find out which one was outputting RIB incorrectly, I made the Polygon Tweaker.

• the slider at the bottom selects the current polygon.
• norm scale
• length of normal when drawn in GL preview
• show all norms
• invert poly
• change the vertex order of the current polygon
• invert norm
• invert normal of the current polygon. See x y z
• x y z
• when inverting normals, this restricts which axes are inverted.
• "batch mode"
• This will invert multiple polygons or normals. Select a range (start at / finish at), whether you want to skip polygons along the way (skip = 1 will invert every other polygon), then press 'invert go'

• Font3D apparently draws some of the polygons with the incorrect handedness. I made a version which outputs RIB correctly (I think), but I havn't tested the other output formats or contacted the author yet.
