sun vs. mplane

by Desmond Fletcher · in Torque Game Engine · 02/08/2002 (2:46 pm) · 1 replies

When the sun direction parameters in the mission file are set to 0 0 -1, there is a fatal error "no plane possible". This comes from math/mplane.h@228. Obviously, in this case of the sun directly overhead, there are only two points defining the plane so the normal can't be calculated.

I'm not familiar with this code, so I'm not sure what the solution is. I tried simply ignoring those edges (all the edges on a polygon parallel to the sun's rays are degenerate), but then the lighting didn't work. I put it on the bug list for now.
