Yes there is
I've tried setting the 'MainCamera' and 'ForegroundCamera' to the same position etc, still doesn't work if that's where you're trying to point me ^^
SetEntityMatrix(fgcam,GetEntityMatrix(cam));
copies the 'MainCamera's position etc anyway, so just do as I said up there and replace the line:
PositionEntity(cam,Vec3(0,0,-1.5));
with
PositionEntity(cam,Vec3(0,0,-2.5));
In the last of the program examples in your 'Transparency and Refraction' tutorial.
