Maybe a bug with multiple contraint in apex scene animate.
Here is my scene with eletra and a box as a weapon.
This weapon has two controls,point_0 control,and world control as a parent of point_0.
Now world control has been constrainted by left hand,and point_0 has been constrainted by right hand.
If i move eletra's left hand, the world control is following,good.But the point_0 control is also following,which is not supposed to happen.
This is quite common situation when working with complicated animations,when characters interacting with props or other stuffs.
But I am not sure if there is other ways to setup correctly,so please open this scene file and test it.
(I'm using 20.5.487)

It's a current Houdini 20.5 limitation that multiple simultaneous constraints are not resolved. This is being addressed for the next major release.

Thank you for your reply.

Hi, I jsut found this topic after trying to get some constraints working with Apex.

I've been trying to get a character to pass an item from one hand to the other, with the object following the first hand correctly, but then it not working when I try and then 'pass' the item by constraining to the other hand from the following frame onwards.

After seeing this thread, I'm guessing that this is currently not possible?

Looking forward to seeing how this workflow improves!
