Thank you Jane very much for your time, but this also wont work. About second solution - attach invisible model to player, this also wont work beasuse invisible models cant cast shadow.

I also try delate shild from my player model and i attach shild troungt code, to one bone, like new model but i have same problem.

Ok, my next questions is:
1. Of which things precisely depends the scale x/y of my shadow sprite?
2. How resize sprite for decal shadows on one entity?
