Hey! I inplemented a particle engine into my first 3d engine, I render the world first, then I have to turn off depth testing (OGL) before rendering the particles. Is there a way to keep depth testing on?

No, only that since I disabled depth testing while drawing the particles, you can see them thru the floor / walls / etc..

hmm, that''s relatively hard to tell from the screen shot. maybe turn depth testing on but use a painter''s-like algorithm.

Sorry bad screenshot.

See the explosion? I need to figure out how to clip the parts that are in the floor / wall / etc out, like how quake3 does it.
