So if I want to create a really fancy and beautiful 2d effect of a campfire I open After Effects, create the effect and then export 2d animation as a .xml file, png sequence etc. And it works anywhere - Unity, Unreal Engine...

Can I create that campfire effect in 3d, so I could paste it anywhere I want? So it would be an independent 3d visual effect file? I know that you can create particle effects in most game engines but I am asking specifically about the independent visual effect file format and software with which I can create it.

If I ask thison the wrong forum, please tell me where can I find the appropriate one
