Engine Flames

A rocket engine's flame as burning gas: white-hot at the nozzle, cooling through yellow into ragged orange tongues, drawn as a true volume.

• What burns shows: kerosene blinding, hydrogen a pale veil with shock diamonds, a nuclear engine a faint red.
• The air shapes it: a narrow column at the pad, wider as the air thins, a clear lobe in a vacuum.
• It moves as fire does: it wavers, trails when the ship turns and spreads over the pad.
• Starts and stops as real engines do: the flame builds as an engine lights, falls back as it stops, flickers as the tanks run dry.

For KSP 1.12.x. Needs Keystone 0.9 or later and Volumetric Explosions 0.8 or later. (0.4.0's re-entry fire is taken out in 0.5.0 while it is made again.)

Works on: Mac: tried. Windows 11: tried, all but 0.5.0's starts and stops. Linux: not run.
