Layer blend per bone - it seems to be ignoring the layer blend?

[crEA-tEch]

Hello there, I’ve created a blend space which changes whether or not the character has a torch. This works fine.

I need the player to be able to “grab” an item. The character should show the grab anim montage and not affect the left arm (whether or not the player is holding the torch should not make a difference).

However, the players left arm is being affected by the anim montage even though I’ve set the grab animation to the “RightShoulder” slot.

Here is an example, watch the left arm move when the grab animation is showing…

Here is a short video of my blueprints and montages etc…

Is there something silly I’m missing here? I’ve done blend per bones before, but only vertically (upper body/lower body/head) etc, and that seems to have worked, but this is this first time I’m using it on arms. The skeleton was downloaded from mixamo.

Here is the call for the montage:

Hi there, you may want to separate the nodes, one per each arm:

Wow, that simple L.F.A! Thank you so much for taking the time to help. Working like a charm. So the layer blend per bone node is only for one blend, and not multiple?

Hi, glad it helps. Typically, I use in pairs. If you use more than 2, makes more complicated, you may need to control the values of “blending alpha” with variable type boolean (to be converted from boolean to float) or float variables ranging from 0-1.
