Fractal Noise 3D constructs a genuine 3D noise field in space rather than simulating depth on a flat layer. Your After Effects camera moves through the volume, and point, spot, directional, and ambient lights illuminate it from any direction, producing volumetric rendering of clouds, fog, and atmospheric effects entirely inside After Effects, with no round-tripping to an external 3D app.
The volume can be shaped with several geometry types, including Box, Sphere, Sphere2, and Cylinder. Domain Warp, added in Version 2, deforms the noise sampling coordinates to add flowing, vortex-like detail through Twist and Vortex modes. Any 3D layer can act as an obstacle inside the volume, casting shadows through the fog or transmitting light for backlit translucency and god-ray effects. Depth Map compositing imports grayscale depth renders from any 3D application so volumetric effects blend with external CG and live footage.
Rendering is GPU-accelerated via Metal, CUDA, and OpenCL, with Multi-Frame Rendering and 8, 16, and 32 bpc color depths supported. It runs in After Effects 2020 and later on Windows 10 or later and macOS 11 or later, including Apple Silicon.
