Hi! When I look at the relevant documentation: http://docs.unity3d.com/Documentation/Manual/AnimationLayers.html -> I cannot get to the settings shown on the second&third pic, where there are two types of "Masks" : "Humans" "Bones" available in the newly added Animation Layer. I only get one single "Mask" as in the first pic... The selection window for this "Mask" remains empty, even though I already created my own "ArmsOnlyMask", so I can't get my mask to be used in the new animation layer. I tried to mark this in the pic attached.... This is the step described at 44:27 in this tutorial video: http://video.unity3d.com/video/7362044/unity-40-mecanim-animation-tutorial The surface simply never looks like this for me when I add the second animation layer... What am I missing here? Thx!
