Use the Collapse Layers button to convert all the current animation in your layer stack to one layer. CAT will plot all your animation down to one layer using consistent sampling.
Collapse to Existing/New Layer
If you select an existing layer in the layer manager and click the Collapse Layers button, all the current animation will be plotted onto the selected layer.
Alternatively, to plot all the animation on your CATRig to a new layer, highlight the (Available) layer and click Collapse Layers.
