xefx: Z-Angle Limitations

Hello... I have a doubt with xefx's zangle option.

I was trying to completely turn around an effect: 180 degrees. When I set the zangle value in the xefx to bj_PI or -bj_PI, the effect is shown at bj_PI/2. or -bj_PI/2., respectively (at 90 degrees). It seems the limit for the zangle is between -90 and 90, because the effect is always shown either pointing left or pointing right, no matter the value I set to zangle (as long as it is less than -bj_PI/2 or greater than bj_PI/2). I would like to know why this happens, and if there is a way to flip over the effect like I want to and go over the 90 degree limit.

Each angle requires an animation in the dummy model, so to have those other angles, the dummy would take twice the space. Yeah, it is probably meaningless, but the logic is that you could just change the unit's facing angle to be the opposite, it is not the same per see, but it is better than nothing.

I am not saying it is a good idea it is limited like this, I have just figured out it would be better as I was reading this post. It is just that back when I was adding the animations to the model, I didn't think it would be needed.

Ahh... okay. In that case, I'll just stick to creating a dummy unit and setting the pitch angle to -180. Thanks for the explanation, though!
