look at question

Hi there,
what can be an elegant solution to create look at for two different geos.
one will able to rotate only on y axis.
second will able to rotate only on x.

thanks !

Take a look at the Blend Component, which can combine different input transforms, taking portions of each.

Cheers,

thanks Rob, very useful. :ugeek:
was able quickly to do what i wanted,
Maybe few examples can explain the whole system options.

Hi Rob,
other than getting into angle calculation with dot product etc,
how would you generalize this idea to N instances ?

Imagine circle of stage floor lights that made of 3 parts
2 of them rotate ,
one part on x axis
the second part on y axis.
both rotation derived from common look at vector.

as writing this I will try different approaches

In that case Blend might not help.
It mostly zeros out portions of a parent transform.

IK solution, where the end afffector is is target, but that doesn’t let you limit rotations easily.

Maybe if you submit a picture of a light.
