Get sprite center in shader

I need to get sprite center in world coordinates inside shader. How can i get it? I make a shader that tint sprites, using light map texture.World consist of cells, every cell have color. Something like this. Example When sprite is fully inside cell, everything ok. But when sprite bigger then cell, or near the cell border.It use two diffetent lights color.And it looks bad. My idea is use center of sprite to find it light color. But i can’t get center in shader. I can’t use sprite.set_consta…

For now I set position of sprite center as shader uniform. But if I can do it in shader it will be better.

There currently is no good way to do that.

Why? You set world matrix for models. Why not set it for sprites?
