Strength

– This parameter controls the strengths of the noise applied to a baked simulation.

– As for all parameters in the Tab Noise You can tray different values without baking again the simulation.

– The higher the Strength value the bigger the noise effect on your simulation.

– Note: As you can see I didn’t apply any denoiser to this simulation to better appreciate the noise added by this parameter.
