Hi, I believe like mastone said it's down to filter size and map size. With depth map shadows the light basically projects a texture into the scene and creates a shadow map based on it. If the texture is too small then you will get stepped edges, unless you use a larger filter size (which will blur the stepped edges together, simulating soft shadows). If you want sharp shadows you need to use a larger map size but with a lower filter. So small map + high filter = soft shadow edges. Large maps = sharper shadows. Hope that helps, cheers gubar
