How to make an animation clip on Unity to loop
unity-game-engine
Solution
Its probably too late to help you with this, but just incase anyone else has this issue, your looping options are greyed out because your animation from the asset store is read-only, select your animation in the project window, and press Ctrl+D to duplicate it, and you should be able to now set the looping options on the new animation as the other answerers have described.
Problem
I am using the Unity Mecanim, and I have two animation clips: The problem is that when the animation of a clip finish it doesnt start again from the beggining, it doesnt loop, and I cannot find any option to make it loop. Any help, where to look for the loop options? EDIT: I find the options according to the answers here but there are not editable, is it because I download this from Asset Store?
