I made a custom sprite, of a cartoon-esque watercolor fire.
When I use an env_sprite as additive, so that the black of the sprite is the background, an odd error occurs. There is a line of color across the top of the sprite that... well... just ruins the effect. it appears to be just floating there.
Now, why vampiric you ask...
Well, I would have included a screenshot, but whenever I take one, the line does not appear
this is probably pretty simple, as it is my first time making a completely custom sprite (Using the ever simple sprite wizard).
When I view it in the sprite viewer, the line does not show up...
I'm using palette maker to create a... well blended palette for all my different frames...
