Mitsuba-Blender 0.1.0 — Blender 5.1 Extension

Export Blender scenes to Mitsuba's XML scene format for offline rendering with the Mitsuba 3 (https://mitsuba-renderer.org) physically-based renderer.

This release is a maintained fork of the original mitsuba-renderer/mitsuba-blender (https://github.com/mitsuba-renderer/mitsuba-blender) plugin, updated to work as a native Blender 5.1 extension with automatic dependency installation.

What's included

• Mitsuba 3.8.0 and DrJIT 1.3.1 are bundled — no manual installation required
• Export meshes, materials, lights, and cameras to Mitsuba's XML format
• Import Mitsuba XML scenes back into Blender
• Render directly from within Blender using Mitsuba as the render engine

Changes from upstream

• Ported to the Blender Extension format (Blender 4.2+, tested on 5.1)
• Updated for Mitsuba 3.8.0 API (ThreadEnvironment, ScopedSetThreadEnvironment, and WriteXML removed upstream — bundled locally)
• Updated for DrJIT 1.3+ array comparison API
• Updated for Blender 4.0+ API (calc_normals, distribution types, sampling patterns)
