Hi, I'm having a little trouble trying to understand how Sync Layer works in Mecanim. From the Docs it looks like you can have a base layer which contains machines/states/blend trees and then replace the animations on your new layer with different versions. Official docs: "Sometimes it is useful to be able to re-use the same state machine in different layers. For example iyou want to simulate "wounded" behavior, and have "wounded" animations for walk / run / jump insteadof the "healthy" ones. You can click the Sync checkbox on one of your layers, and then select the layer youwant to sync with. The state machine structure will then be the same, but the actual animation clips used by the states will be distinct." Now I've got my base layer all setup with my states, sub machines and blends. I've got another layer above it called "Arms" which is responsible for the aiming of a weapon. I would like to sync the base layer to the arms layer and replace the base layer animations with weapon aiming animations. However, after I click sync, I see the base layer states copied across, but when I double click they're empty. Also, it looks like I'm always in the BaseLayer in the Animator Window! I keep trying to select the "Arms" layer, but the layer name at the top of the window always says "Base Layer". I'm just not sure how to use this whole Sync system and it's workflow is not apparent to me. The docs state that the entire state machine will be copied across. Well, no, the names get copied, but the internal blend trees and sub machines are empty. After pressing the Sync layer checkbox, it seems after select that layer I'm in a weird state where I'm half between the base layer and my Arms layer, very confusing. Anybody know any tutorials that explain this system better than the official docs?
