InteractionEngine Brush Hands help needed!

[ipstatic]

Hey ! I am currently working in a student project to make a simulation of a robotic hand attached to a robot arm.
In our showcase we would like to show our robot moving and grabbing objects.

We had hard time locking the hand onto the robot arm because of the leap controller only making "flying hands" environments.
In the hurry, we just deleted the lines in the RiggedHands Script that makes the palm of our hand move with the leap motion data.

But now we have a new problem and we can't manage to find a decent solution.
We are using the Brush Hands in order to use the interaction engine from leap motion module but the physic hand is flying and moving around where our graphic hand isn't. We would like the brush hand to be locked with the graphic hand. Any idea to solve this problem or any lead on how to ?

Here is an example

Thank you really much for your help, really appreciated.

I don't think this is possible (at least not without re-writing much of the Interaction Engine Unity code). The Interaction Engine sends data to its own mini-physics engine, so just changing the update method of the InteractionBrushHand object like you did for the rigged hand is unlikely to work.

Ok ... That's disappointing
Would you have any idea to work around this problem ?

Use RigidHands for physics and pick up based on proximity and the hand's grab strength and pinch strength properties. It should seem appropriately robotic.
