What It Helps You Do

  • The report opens in a web browser and refreshes automatically.
  • By default, the profiler shows data from the viewport. If you want to get information from a render:
  • Switch the profiler to render mode by clicking Render on the report page.

How To Install It In Blender

  • Install it from Blender Extensions inside Blender when available.
  • If you need the ZIP directly, use the official download from the Blender Extensions page and Blender’s Install from Disk flow.

How To Use It In Blender

  • Official docs mention: Render Profiler.
  • Official docs mention: Where to find it?.
  • Official docs mention: How to get information about rendering?.
  • Official docs mention: Topbar indicator.
  • Official docs mention: Modes (mode switcher in the report).
  • Official docs mention: Current Limitations:.
  • Official docs mention: Technical notes.
  • Official docs mention: Memory size calculation.
  • Official docs mention: Curves (hair / Geometry Nodes).

Using It On A Render Farm

Simple guidance for rendering node setup, and safer submissions.

Background Rendering: review
Worker Install: review
External Files: review
Conservative install assumption

Conservative default: assume workers also need this add-on installed unless you have verified that its output is fully baked or converted into native Blender data.

Warnings

  • Network-related code was detected. Any online lookups, licensing checks, or downloads should be tested before relying on farm execution.
  • Local path or asset-library signals were detected. Paths that work on the artist machine can still fail on remote workers.

Safest Workflow

  • Check whether the add-on launches its own render operators locally and avoid assuming that workflow maps cleanly to farm orchestration.
  • Open the scene in desktop Blender, run any interactive setup steps, save the file, then validate a small background render before scaling up.

Packing Checklist

  • Assume every worker needs the same add-on version installed unless you have verified that the scene renders correctly after baking or exporting the result to native Blender data.
  • Upload any external textures, presets, asset libraries, exports, or helper files referenced by the add-on workflow.
  • Run a small local background render or one short farm test before full submission.

Common Issues

  • The scene opens on the farm but renders incorrectly because local assets or helper files were never uploaded.

More Context

Press F12 in Blender to start the rendering process. Once the data is initialized, it will be available in the profiler.

When profiling is on (Viewport or Render), the top bar shows a short line: Profiling (Viewport) or Profiling (Render) with X button. Use X to turn profiling off or press on indicator to open new report page in the browser.

Performance Notice: Data collection adds some overhead, so slightly worse performance while profiling is expected. If you have issues, consider pressing Off in the report to stop scene profiling and use profiler on demand.

The Memory tab shows estimated memory for geometry and textures.
