Parameters might not affect as expected.) 19 | - Edit properties of the explosion by editing "ExplosionMaterial.tres". 20 | - Emission Fallof Multiplier and Emission Falloff control how fast the flames disappear. (Emission Fallof Multiplier can result in visual problems, I keep it at 0.5) 21 | - Emission Color Ramp allows to modify the color of the flames. 22 | - Smoke Color Ramp allows to modify the color of the smoke. 23 | --------------------------------------------------------------------------------
