What's new

0.9.0

Added

  • Nothirium support, including RenderLib-aware entity render distance limits.
  • A vanilla-style Extra settings screen with two-column buttons, sliders, category submenus, tooltips, and reset controls.
  • Pintonium compatibility. Extra settings are accessible from a button in the top-left corner of its video settings screen, preserving Pintonium’s own search and shader controls.

Changed

  • Modern Clouds now override resource-pack cloud textures while enabled. Disabling the option restores the resource-pack texture.
  • Moved Java packages to com.sumirelabs. Existing configuration files remain compatible.

Fixed

  • Fixed a texture animation Mixin conflict with LoliASM’s on-demand animation system.
  • Fixed F3 cache handling to prevent duplicate renderer information with Nothirium and RenderLib.
  • Fixed a crash when opening Pintonium’s settings screen. #37

Requirements

  • Cleanroom Loader 0.6.10-alpha or newer
  • Java 25
  • Exactly one renderer: Celeritas, Actinium, or Nothirium
  • Nothirium requires RenderLib; Nothirium 0.4.9-beta or newer and RenderLib 1.4.5 are recommended.
  • AssetMover 2.5 or newer is optional and required to download the Modern Clouds texture.
