For the modders:
I have a idea:
If some anim maker wont
You could create a gesture never seen
In tennis elbow
For ex:
Victory. Anim: player up your arm and you run the net,
or turns to the tribune
Or the player fi ti the net and extends his hand to the opponent
Stupid. anim (or other): the player focuses on head
Low while the strings of his racket
You can create other version of walking anim, whit janowiczs style that walks sideways wondering com the racket balls
Are just ideas .... ...
You are all very good ... Thank you very much for your contribution
