You don't need any material to create a vibrating VCI.
Prepare a 3D model based on what you want to create with VCI.

You can easily check this by creating a grabbable SubItem.
Also, set the component as shown below for easy handling.

• Collider…Enable IsTrigger
• Rigidbody…Enable IsKinematic, disable UseGravity
• SubItem…Enable Grabbable

main.lua

function onUse(use)
    -- use stores the name of grabbed SubItem
    vci.assets.HapticPulseOnGrabbingController(use, 3000, 1)
    print("Vibrate a controller which used"..use)
end

The argument “use” in onUse(use) contains the name of the used SubItem as a string.
By using the “use” as the argument on the vci.assets.HapticPulseOnGrabbingController(use, 3000, 1), you can vibrate a controller with any objects when used.
The second argument specifies the strength of vibration (0～3999); the third argument specifies the length of the vibration. HapticPulseOnGrabbingController

If you want the vibration to occur with a specific SubItem only, you need to separate the process with “if” statement depending on the used SubItem.
