This is great! It's much better than the stock effects in ArmA.
Suggestions:
Reduce the clumping of some of the the dust and smoke in some of the larger explosions (to reduce fps degrade is it possible to render some of the symmetrical effects [such as explosion rings] as one same-point particle? I'm not literate in modelling so I wouldn't know.)
My fire looks like it is spinning on a vertical axis (similar to a glitch in the original WarFX), but I'm not sure. It might just be the rapid change of the emitted fire effect.
Edit: I'ts spinning, I can tell after looking at it in slow mo, it looks like most certainly like this. Please looks into this if you can. :smile:
That's all, I'll edit in any other suggestions if I can.
