I have code which creates a point source of light and attaches it to a prop named "target" which, in turn, is parented to another prop. It basically works fine except that the yTran for the new light is off by a bit.  yTran on the target is modified by a Master Parameter called BeamWidth, which seems related.

Here's where I get when I run my script, and you can see that the point light source is *not* centered on the dense ball ("target"). The light is created, parented to target, and then has all its coordinates set to zero. Everything is property aligned except for yTran.

I think that the problem is related to the use of a Master Parameter which is used to move target within a limited range. For this image, the parameters of target look like this: . The yTran of the light is zero and needs to be .004 (!!) in order to be properly centered. No matter where I position the target and no matter how I scale target, the yTran of the light needs to be .004. I'm guessing that somehow I need to factor in the Master Parameter, but I have no clue how, nor do I understand why .004 is the magic number.

Any suggestions?

The origin of the ball mesh geometry may not be in the center of the ball.

In fact, the two are totally unrelated.

Thank you. That was probably exactly the insight I needed. I shall go futz with that and see where I get.

That's it!!! When I look at the parameters for the target, I see  and there's my ,004. Now for some code adjustments. Thank you again!
