would anybody tell me please,

I’m getting that too, Idk what to really do. The best solution is to import those sprites as textures with their own materials, and to use cubes that are thin on the z axis; you can animate the sprites via script by changing the materials of the given object. This will take time, but it will pay off in the future. Also I found another way of going about this: rage pixel is a great free resource for 2d development without all the work. I’ve used it in an old project called Hildonbraek if you wanted to see what you could make with ragepixel.

You should use Sprites > Diffuse shader.
