Free Snow & Ice Generator (4.5 Updated)

PinSolver is a Blender add-on that uses OpenCV's PnP algorithm to align cameras and objects by linking 2D image points to 3D coordinates. It covers work from static placement through to video matchmoving.

Compositor Pro is a Blender add-on and a collection of high-quality nodegroups spanning effects and utilities, aimed at producing higher quality renders. It lets you apply complex effects like lens flares, halation and film grain in one click.

Particles Box is a Blender add-on for adding atmospheric and particle effects — fog, rain, snow, leaves, dust, fluff, butterflies and flies. It supports Blender versions 3.6 through 4.2 and ships with documentation.

Aqua Under Water Addon is a Blender add-on for building underwater environments. It creates adjustable water surfaces, includes presets for oceans, rivers, and lakes, and provides underwater lighting, fog, and particle tools alongside a free diver model.

Auto Track Weights is a Blender add-on that automatically modulates the influence weight of tracking markers in motion tracking, fading weights near the edges of tracked regions and across gaps to improve solver stability.

Fluid Painter is a Blender add-on that uses Geometry Nodes to paint fluids over any 3D surface with a curve. It ships with 30+ presets compatible with Eevee and Cycles.

Alt Tab Easy Fog adds volumetric materials to Blender, with more than 35 presets and one-click automatic fog for atmospheric depth and lighting effects. It's compatible with Blender 4.0 through 4.5.

Baga Rain Generator adds rain to Blender scenes using geometry nodes, affecting only surfaces exposed to the rain. It includes a procedural rain shader generator that overlays onto existing materials.

Camera Tracker 6 is a Blender add-on that uses photogrammetry to produce automatic camera and tripod solves. It also handles rotomation, variable focal length, dense point clouds, pinning, undistortion, and object tracks.

Alt Tab Easy Fog 2 is a Blender addon for adding realistic volumes like fog, smoke, and godrays. It bundles over 50 procedural materials, more than 100 VDBs, and a range of abstract shaders.

Khaos: Ultimate Explosion/Destruction Add-On brings explosion and destruction tools to Blender, bundling two versions—KHAOS Detonator for procedural mesh explosion systems and KHAOS Legacy for smoke, debris particle effects and rigid body fracture tools.
