Interaction Layers not working correctly

[brianchancellor]

Hey,

I have been working on adding interaction/grabbing objects to my scene. I have downloaded and looked through all the examples and redone the steps listed in the documentation. I cannot get it to work in automatic mode nor can I get it working when I set the layers manually. I have the brushHands on the BrushHand Layer, the interactable cube I want on the interaction layer, and everything else on default. But as soon as I touch the interactable cue, I get this error.

For interaction to work properly please prevent collision between IHandModel and InteractionBehavior. Cube(Clone) , palm
UnityEngine.Debug:LogError(Object)
Leap.Unity.Interaction.InteractionBehaviour:OnCollisionEnter(Collision) (at Assets/LeapMotionModules/InteractionEngine/Scripts/InteractionBehaviour.cs:519)

I cannot seem to figure out why. I have set up the layer collision Matrix how it describes in the documentation. I have also tried alternate configurations as I have read in other posts. (see https://community.leapmotion.com/t/interaction-engine-and-layers/5576) Any help getting this to work would be appreciated.

Thanks

Do you get this error in the example scene, too? Or just scenes that you create yourself?

[brianchancellor]

Just on the scene of my own creation. If I open the interaction example example here, It is set to automatic and has no layers set up. When I run the example and pause it to see how the system is set up, It just seems to work automatically but not for my own scene and I am unsure why. I have even imported the hand setup from the example into my custom scene but to no avail.

It's hard to debug without seeing the scene itself. Can you share a project the contains the problematic scene?

[brianchancellor]

I have uploaded the version with the interaction engine that is causing me trouble. Check out this repository(https://github.com/theChancellor/Debug_LeapMotion_interactionengine). The scene in question should be the only scene directly under assets named Leap_Hands_Demo_VR. Thanks for the help.

The problem isn't with the layers (though the error message is similar, which is probably why I didn't notice in the first place). The problem is that you are using the rigid body physics hands and the Interaction Engine at the same time. You can use straight Unity physics through the rigid body hands or you can use the IE-modified physics with the Brush hands, but yo cannot use both at the same time. Your options are to either remove the rigid body hands (use the AttachmentHand object for access to the transforms of the parts of the hand) or to turn off collisions between the rigid body hands and any intractable objects (i.e. make it so the default layer does not collide with the Interaction or InteractionNoClip layers).

Thanks so much for this! Finall figured it out with your help Joe!
