Hi Jane,
problem is i cant set stencil shadow this will >KILL< frame rate in my big levels, and this is reason why i need decal shadows.
My hull not changed after i play attack animation, only sprite scale x/y:

I do not know how decal shadow take size for my player, but if i have frames like in first picture from MED, then shadow sprite get scale of this frame - distance of the player to the final point where ends flying of shild.
