i think agkv2 did not have 3d particles.
but smoke are just some 3d squares with a smoke texture rotating up in the air and fade out.

You should use alpha blending. Light areas blend to form brighter areas.
I can't grab it on this laptop, but I made a nice background smoke effect with one image of swirly dark and light patches. I flipped one sprite, set it to alpha blend mode and scrolled the UV coordinates. It is very effective.

I knew this will be useful, but I think it was back then not so popular to use 3d:
