BlueVelvetLib

BlueVelvetLib is a collection of tools for voxel models that move by the laws of physics.

This is the first release, so please report any bugs or issues you run into. Every report helps!

What you get

• Living wind: a real wind simulation that flows around hills, trees and buildings. It is calm behind walls, speeds up in gaps and gusts on open peaks.
• Clouds that drift with the wind, both vanilla clouds and BlueVelvet's own soft volumetric clouds with shadows.
• Wind effects: smoke, flames and embers lean and drift; leaves and flower petals are torn away in strong gusts; sand, snow and dust blow off the ground; rain and snow fall at an angle.
• Cloth physics engine: fabric that hangs, sways, folds and reacts to wind and movement (used by VelvetCape for capes).
• Shader support: grass and leaves in Iris shader packs sway faster in strong wind.
• Wind Rose: a HUD compass that shows wind direction and strength.

Compatibility

• Fabric and NeoForge, Minecraft 26.3 and 1.21.1
• Works with Sodium and Iris (settings page in the Sodium menu)
• Every effect can be tuned or turned off; quality presets and a low-performance mode included

For mod developers

BlueVelvet ships a public API for cloth, wind and physics. A documentation page is coming with the next release. Open source API will be delivered soon.
