Download for Windowsdev3-R8 · ZIP

Extract the entire ZIP, then open chromamatter-orca-dev.exe. Settings are shared with earlier CM trials: back them up and close older versions first.

Extract on your Mac and open the app. Ad-hoc signed only; no Developer ID or notarization. Settings may be shared with older CM builds.

Experimental software, not a stable release. Keep originals and work on copies.
Mac and Linux build/package checks passed; real-model GUI operations, slicing and printing on these platforms remain unverified. The latest R8 Windows protection changes have not had a final GUI verification. Always inspect the sliced result before printing. This is an unofficial Snapmaker Orca modification.

In dev3-R8

  • Three colour modesFlat Color, Full Spectrum and experimental CMY recipes from coloured GLB/OBJ models.
  • Paint & shadingBrush and fill tools, colour replacement, palette cleanup and shading adjustments.
  • Part cuts & protectionPlanar cuts with position and angle controls, optional range planes and brush protection.
  • Connectors & bridgesAttached plug connectors, hole clearance and two-point cylindrical or square bridges.
  • Plate-aware checksFor eligible Flat Color projects, uses each plate’s actual materials for validation. A four-tool printer still needs no more than four physical filaments on each plate.
  • English & JapaneseColour-editing and cutting workflows in the same application.
Setup notes & current limitations

Extract into a separate folder. Back up settings and save projects under new names. See the release README for dependencies, launch instructions and SHA-256 values.

  • Windows is an extracted app bundle, not an isolated portable profile. It shares the ChromaMatter_Orca_240_MaterialHover / ChromaMatter_Orca_Dev settings location with previous builds.
  • Mac requires Apple Silicon and macOS 15 or newer. Intel Macs are not supported by this package. Ad-hoc signature and command-line checks are not a substitute for real-device GUI testing.
  • Linux targets Ubuntu 22.04 x86_64. Command-line, dependency and headless startup checks passed. Other distributions and real-GPU use are unverified.
  • Protection, cuts and connectors remain model-dependent. Check geometry and sliced results. Shape-based cutting remains a developer feature.
  • CMY, TD and Core/Shell are experimental, not optically calibrated. Palette entries do not add physical printer tools; plates are not automatically regrouped.
  • Older CM builds and stock Orca may not reproduce these project settings. The screenshot and demo videos show earlier development stages, not an R8 test certificate.
