To make a grid, set the cannon velocity to 0.Īs for the persistent and ephemeral stuff, I’d have to check the manual for that. Particle Playground particles do not exist in 3D space. You must precompose a layer that has had an effect applied if you want to use it as a layer map. Recall that white has high values for R, G and B. When a particle is at position (x,y), it reads the map’s RGB value at that position (x,y) then multiplies the chosen property value by that number, with or without another factor you set. If the particles are static, using a movie as a property map can cause them to change properties based on the colour of the movie in the property map. As the particles travel left-to-right, they travel through the black, then red, then black. If you want the particles to get bigger then smaller, the ramp should be radial: red in the center, black around the edges. Translate Jump to answer 2 Replies Jump to latest reply Correct answer by DaveLaRonde LEGEND, Precomp the stuff that makes up the border. The tutorial concentrates on making snow stick to actors and things more than on being realistic looking snow. Hell also shows how to make the snow stick to other layers in your composition. A mask will appear that you can use as the emitter path. Jerzy Drozda Jr (aka Maltaannon) demonstrates how to generate snow using Particle Playground in After Effects. Use the Auto Trace command, basing it off the alpha channel. As the particle passes through the black zone, it is small, then as the R value increases as it moves to the right, it gets bigger. Precomp the stuff that makes up the border. So, if you want particles travelling left-to-right across the screen to get bigger as they move, the property map should be an image (or precomped layer) that has a black-to-red linear ramp applied: black on the left, red on the right. size) of a particle when it is at that same position. R) at a specific position on the map affects the chosen property (e.g. The RGB map is an image or movie that you design. Did you try Googling “particle playground” and “tutorial” together? There should be some tuts there.
