Nebulosity – plugin for After Effects
Nebulosity is a GPU-accelerated After Effects plugin. It generates volumes with help of Noise, Layers and Ramps that can be colorized with different techniques. Creates nebulas, galaxies, clouds, smoke and more.
Nebulosity uses a raymarching algorithm to visualize density. Density is calculated using Noise combined with Layers as Masks and Ramps.
Set base bounding shape of volume with box or sphere. Customizing the shape is possible with custom layers in Cut or Extrude mode. Ramps can also be used to mask the volume. Edge of volume can be nicely smoothed with Feather Ramp.
Set density with up to 3 layers of different noises. Scattering noise can be three different types: Volume noise, Spiral noise and Inverted FBM noise. Each noise can be fine-tuned and animated with an Evolution slider.
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 distribution.
- Up to 10 Point Lights can be used.
- Generate and distribute stars inside volume.
- Post Effect Mosaic transform volume to pixels.
