Nebulosity
Nebulosity is a GPU accelerated After Effects plugin. It generates volumes with help of Noises, Layers and Ramps and colorize it with different techniques. As a result plugin can draw nebulas, galaxies, clouds and smoke
How it works?
Nebulosity uses raymarching algorithm to visualize density. Density is calculated using Noises combined with Layers as Masks and Ramps.
Base Form
Set base bounding shape of volume with box or sphere. Customizing shape is possible with custom layers in Cut or Extrude mode. Also Ramps can be used to mask the volume. Edge of volume can be nicely smoothed with Feather Ramp.
Combine Noises
Set density with up to 3 layers of different noises. Scattering noise can be four different types: Volume noise, Spiral noise, Worley noise and Inverted FBM noise. Each noise can be fine tuned and animated with Evolution slider.
Emission Gradient
Emission source for volume can be Color, Layer or Gradient. In Emission Source Gradient mode, Gradient can be distributed by Density or Radial from center or by Noise. In both Density and Radial modes noise can affect on distribution.
