What's new

v2001.4.0.1 Release | Oct 22, 2026

🐛 Bug Fixes

  • Screen effects, skyboxes, world effects and ghost blocks no longer leave the game believing its own shader is still bound. Vanilla skips binding a core or post shader it bound last; after one of CoolCatLib's programs, the next draw with that shader could run with the wrong program (or none) and send its uniforms to it.

🔧 Changes

  • CoolCatLib's shader programs remember their uniform locations and the values last sent, so a uniform set to the value it already has (samplers, unchanged matrices, every frame) costs no GL call, and matrices are sent without a temporary buffer.
