GLTF & layering- moved objects up a layer are clipped/hidden

I’m attempting to move children of a glft scene up a layer, and apply a render pass. Moving the children up a level I’m able to render them differently, but while they are positioned correctly, they are now clipped/cut off from the scene they are still a part of. How can they appear in place?

As in the gltf initially

After moving children of the glft to layers(1)

Any help would be greatly appreciated!
