Counter Strike 2 releases soon and it comes with some very innovative smoke grenades! But, how do these smoke grenades work? Why can't anyone properly recreate them? and can I crack the code?

Topics covered include: Frame debugging, voxels, mesh voxelization, flood fill propagation, ray marching, volumetric transmittance, volumetric shadows, worley noise, phase functions, and signed distance functions.
