Design and production of explosion effects in games
Author:
Learn to use the particle system to complete the production of explosion special effects, from the theoretical analysis of the basic explosion to the selection and production of texture maps, and decompose the various parts of the explosion special effect step by step from the general effect to the details. Learn about occlusion at the emitter level by stacking particle emitter groups. Analysis of the principle of special effects:
Since most explosions are detonated by flames, flame elements account for a large proportion of special effects production. This special effect of expressing damage should emphasize the visual impact and destructiveness, and adjust the strong exposure of the explosion and the dynamic performance of the flame smoke texture.
The core texture of the explosion effect is the flame, and the flame sequence texture is used first. Use the radiant light texture as a strong exposure point. After the instantaneous exposure and the flame texture appear, the flame background texture is also required. As shown in the figure, due to the expansion of the air caused by the explosion, there will be shock waves that spread around, and the explosion flame will not burn completely. After the explosion, there will be a lot of black smoke and unburned impurity sparks.
