Ello CG Society!
I created a lowpoly generic human model in Maya this week for testing all the new Mixamo and Unity products. My character was very easy to Upload to Mixamo, auto-rig by the Mixamo website, apply animations, and then i was able to download just what I needed to get me going in Unity.
Once in Unity, after dragging the model (ie Man.fbx) from the project "file tree" window into the scene window, then simply changing the man.fbx "rig" settings to legacy,
and doing the same to the animation file (ie Man @punch.fbx)
I was then able to drag and drop the animation itself
(the icon in the drop down menu of Man @punch.fbx, its a little play button on a dark gray square) into the animation controller slot of the model that I drug into the scene window, and the character is ready to watch inside the game. For this video and Testing purposes, inside Unity I set the wrapper setting on the animation file to loop.
