Sundari Path Tracer v0.1.0 (POC Release — macOS arm64)
==============================================================

Quick Start:
1. Unzip the archive. You can run 'Sundari.app' directly from the unzipped folder, or drag it to '/Applications' if you prefer.
2. First-Launch macOS Gatekeeper Note (macOS Tahoe 26 & newer):
   Because this POC build is ad-hoc signed rather than notarized with an Apple
   Developer ID, macOS Gatekeeper will block the first launch when downloaded
   from a web browser. Choose either option once:

   Option A — Fast Terminal Bypass (Recommended, skips all popups):
   Open Terminal and run on the unzipped app:
     xattr -cr Sundari.app
   (or: xattr -cr /Applications/Sundari.app if moved to Applications)

   Option B — System Settings GUI Override:
   - Double-click 'Sundari.app' and click 'Done' on the "Sundari Not Opened" dialog.
   - Open System Settings -> Privacy & Security, scroll down to the Security
     section, and click 'Open Anyway' next to the Sundari message.
   - Click 'Open Anyway' again in the confirmation dialog and authenticate with
     Touch ID or your Mac administrator password.
   (macOS remembers this exception, so all future launches open normally.)

3. Launch Sundari and press Cmd+O (or drag and drop any .ssd scene package or .usd/.mtlx file) onto the window.
   Recommended benchmark and sample scenes (MaterialX Teapot, NVIDIA Industrial pack, Blender Classroom) are linked on the website.
4. For Blender 4.2+ Live-Link & SSD Export:
   - In Blender, open Edit -> Preferences -> Add-ons -> Install from Disk...
   - Select 'sundari_blender_addon_v0.1.zip' and enable 'Sundari Scene Descriptor (.ssd) Exporter'.
