Question by kashish · Apr 19, 2014 at 08:31 PM · 2dcolorspritesspritesheet

How can I key out (remove) a color from a spritesheet (2D)?

I have some old spritesheets but instead of being transparent the background is black and I can't seem to figure out how to key it out in unity.

You would have to either write you own custom shader or update the spritesheets to use alpha.

Unity doesn't support color key's so you would have to rework it by making the black parts transparent and export it as a png for example. (I use GIMP for such purposes)
