About Property Mappers (PB only)


    Control specific properties of individual particles using the Property Mapper. You can't alter a specific particle directly, but you can use a layer map to specify what will happen to any particle that passes over a specific pixel in the layer. Particle Playground interprets the brightness of each layer map pixel as a specific value (see About layer maps (PB only)). The Property Mapper options associate a specific layer map channel (Red, Green, or Blue) with a specific property, so that as a particle passes over a certain pixel, Particle Playground uses the brightness value provided by the layer map at that pixel to modify the specified property for that particle.

    For example, if you want to control the size of particles at certain areas within the frame, create a layer map and associate it with the Scale property so that the particle size increases as the pixel brightness value increases. Particles passing over lighter areas will be larger than particles passing over darker areas. If you associate the layer map with the Angular Velocity property instead, particles passing over lighter areas rotate around their own centers faster than they would when passing over darker areas of the layer map.
