Any generic way to make animation states and blend trees?

Hi,
I'm looking for any good Post/Blog for controlling animation states and blend trees for your character. I want to know is there any good tutorial which explains how to make animation states for a character to make animations look better.
Right Now, I have almost 20 animations for my character, If I make their states then it becomes very complex.
For Example, If I have Jump,Idle,Run states for a character, should I use state from Jump to Run or should I first go from jump to idle then Run (If user is jumping). I'm a bit confused about their states and looking forward for any blog post which can explain how to control your animation states with the best complexity. Any research paper link would be appreciated.
Thanks.
P.S: I already have commands on beginner Animation states, I'm looking for advanced tutorials/post.

 

May also want to check out any of @TonyLi forum posts. He is very helpful with this.

 

Thanks @theANMATOR2b! Here are two useful posts (one, two). The first is a real world blend tree, but it was posted before Unity 5, so it doesn't showcase any of the shiny new Unity 5 state machine features described in Pierre-Paul's blog.

Also take a look at Opsive's Third Person Controller thread. It's an excellent third person controller, and Justin has posted screenshots of the state machine throughout the thread.

 

Hi,
Sorry for late reply, I had a look into it but this is not what i wanted. Anyways, Thanks for your co-operation.

 

@theANMATOR2b Thanks for your answer, I will look into their posts.

 

@TonyLi Thanks for mentioning opsive's third person controller. This is a paid asset, I cant afford it. However, I will look into other posts of yours to find any solution.
Thanks.

 

The developer, Justin, has posted screenshots of the Third Person Controller's Mecanim state machine. Even if you can't afford the product right now, the screenshots in the forum thread are an excellent free resource to see how a professional implemented this in a real-world product.

 

@TonyLi Thanks for notifying me. I will definitely check it out.
