So I created so 'glowing' led lights on my background (layer 0), and the glow extends outward from the sprite over the background creating for example a green glow effect. But when I add it as a Sprite the glow effect being overlayed just darkens the layer below it, and doesn't blend the same way in Photoshop. It doesn't look horrible, and you can barely tell but it definitely doesn't give off a green glow effect. The layers in ps are all normal blending, and its set to RGB color 8 bit channel.
Any suggestions? Advice? Pointers, maybe some things to try?
