Trying to fix a map. I believe the problem is one particular tile. So to find out, I need to remove the tile and rebuild the map.
Unfortunately, since the tile is a world-geometry change, this means I need to re-render the level also.
Turns out the level's done with 3dsmax 5.1, so therefore I need to get a new version of the editor.
The new version of the editor requires 3dsmax 5.1 to run. So . . . I'm installing 3dsmax 5.1 itself.
Well, actually, I'm not - I'm uninstalling 3dsmax 5.0 right now.
All this, just to remove a single tile . . .
