Getting started

A Blender add-on for room acoustics. It exports Blender scenes to the misuka renderer.

Features

• Export. Export acoustic scenes to misuka and visual scenes to misuka or Mitsuba 3.9.

• Editable acoustic material properties. Edit absorption and scattering coefficients directly in Blender, in octave or third octave bands, with logarithmic and linear interpolation. Bands you set are marked, so measured values stay distinguishable from filled-in ones.

• Acoustic Index lookup. Name a material after a database entry on acousticindex.com and pull its measured coefficients straight into Blender.

Rendering inside Blender is not supported, and neither is importing a misuka scene. The add-on writes scenes; misuka renders them. Set the render engine to misuka so the acoustic panels appear, then export the scene and render it with misuka the way the shoebox tutorial does.

Where to go next

• Setting up: Installation covers the add-on, its dependencies, and the Acoustic Index API key.

• Tutorials: Tutorials: Shoebox room builds a room and exports it in about ten minutes.

• Guides: Scene settings, Acoustic materials, Acoustic Index and Exporting document every panel in detail. See Troubleshooting if you run into problems.

• Reference: Plugin mapping documents what the exporter writes for each Blender component. Scripting names the Blender properties behind every panel. See Contributing if you want to contribute to the project.
