Doubt about effects with black background - Sprites

[Niphura]

Is it possible to rip and use this effect as sprites? or the black background will appear in game?

Here's a test against a random coloured background. This was done in Photoshop, but I'm writing a shader for GZDoom that will do this automatically.

Download video using flashgot and mozilla 56 - using ffmpeg split video to frames - using magick of photoshop/paint remove black background - slade - import - decorate.

Or, you can download it already divided to pictures. You ony left to chose what you like.

It depends on how you do it. Once you render such a thing in a mode where colors get inverted the black will turn into white. This can happen with some items when using the enhanced nightvision effect of the GL renderer.

I've used your example flame sprites in a test for my translucency shader. It's set to replace the Archvile's fire frames. It will turn blacks progressively translucent but preserves the opacity of more saturated colours AND you won't have to do Photoshop editing to remove the black background
It also respects the menu's translucency preferences:

There's a little setup involved:
