This is the fifth component of xParticle Suit, Dissipate. As long as you specify an object, you can create a dissipation effect. By adjusting various parameters, you can modify the material color, dissipation speed and direction, etc. This is built using Blender Geometry nodes, which means you can directly adapt the "source code" to your project needs.If you are interested, you can take a look at my work page blendermarket.com/products/xp...
