Buy him a new engine for 1500 bucks.
That isn't the problem. Torque Game Engine doesn't by default have the
fxDTSBrick. That is something that Badspot (most of it, I believe) and kompressor (oct tree) implemented. I believe that the reason that it only has 90 degree rotation is because it's optimized like that so you won't need to do as many calculations upon rendering.
