About this project
What does Entropy Lib/Cosmic Entropy add?
Entropy Lib is rendering framework made for Minecraft mod developers who want to create visuals far beyond the normal Minecraft style. Its goal is to make it possible to make effects that feel closer to modern games, animation, and media instead of Minecraft.
About Entropy:
Advanced Effects: Create complex, animated, and cool effects.
Custom Rendering: Render shapes, models, particles, beams, trails, and other visuals in completely custom ways.
Shaders: Build unique shaders for objects, the world and the screen.
Lighting: Add custom lights, shadows, glow, bloom, and other light related effects.
Effects: completely change how parts of the Minecraft world are rendered.
Particles & VFX: Create large and detailed visual effects without being limited to vanilla particles.
(mainly an experiment to see what i could do with shaders for my mods)
