Yeah but I don't want it to actually toggle switching between tracking and animations. I just want to disable all animations on one layer. 

When there are two layers with the same mask, with the second set to override, the second layer is ignored so long as it's in an animation state with nothing on it - that's when write defaults are turned on. When write defaults are turned off, once an animation in the second layer is triggered it stays overriding forever; I haven't been able to find a way to return the layer to it's "transparent state" [spoiler]see note about layer weighting later in this post[/spoiler].

Yeah that's what I've been doing so far but as far as I've been able to tell, you have to manually input the actual layer number yourself into the VRCanimatorlayer component; there's no way to "refer to current layer" directly. This is part of something intended for distribution, to be combined with other animators, and I feel like having to count numbers is one step too much for people and people are just going to fuck it up and be confused.
