[LVL ED] bb_yellow_lightray.mat rotation trouble [ANSWERED]

[Tekkie]

I had a look around and couldn't find anything that might fix this little problem of mine...

Basically, I've set up a room with a large window and a bb_lightblue_lightray.mat billboard for a lighting effect. I wanted it to look as though light was streaming through the window, however, when I come to add the bb_yellow_lightray.mat streams, they will not rotate. I can see the box changing shape to indicate that it's rotating, but the actual stream isn't rotating at all, and when I test it out in-game, it's just a straight vertical beam of light as opposed to the 45 degree angle stream I wanted. I've run out of ideas on how to fix it, this is the first problem i've encountered with the level editor, other than the bone_pile_human2 entity freeing the whole thing. Anybody have any suggestions? I'm kinda stuck for what to do and I don't want to continue mapping with crappy lighting effects.
