When I use a normal IWAD, Vavoom builds the gl nodes and the VIS data. Now I just built the gl nodes using glBSP and ran the wad in Vavoom, and Vavoom didn't build the VIS data. Might not be a bug, but it still is curious, no? Gio

I think it's because Vavoom puts the vis data into the same .gwa file as the nodes.

That can't be it; I deleted the gwa file when I repacked the wad with gl nodes.

If you have GL nodes in the wadfile than most probably that's the problem.

Yes, it sounds a bit strange, but if everything is working normaly, it does find the vis data somewhere.
