What It Does
Overview and common use cases for this add-on.
- It opens a live HTML report in your browser with modifier timings, mesh and texture data, and memory estimates.
- The report stays synced with Blender, updating automatically.
- Switch between viewport and render data with a simple mode switcher.
Common Use Cases
- Identify which parts of your scene slow down rendering.
- Analyze memory usage to optimize your scene.
- Get detailed statistics on mesh and texture performance.
- Switch between live viewport and render data to see real-time changes.
Getting Started
How to install and start using this add-on in Blender.
How To Install
- Download the Render Profiler add-on from the Blender Extensions page.
- Open Blender and go to Edit > Preferences > Add-ons.
- Click 'Install' and select the downloaded ZIP file.
- Enable the add-on by checking the box next to its name in the Add-ons list.
First Steps After Installing
- Open the Render Profiler from the top menu in Blender.
- View the live HTML report in your web browser for detailed analysis.
- Switch to render mode on the report page if needed for more information.
Using On A Render Farm
What render farm submitters need to know before sending jobs.
We could not inspect this add-on's code. Install it on your farm workers and run a single-frame test job before committing to a production render.
Scene Prep Checklist
Complete these steps before uploading your scene to a render farm.
- 1
Install the same add-on version on every render worker
Required - 2
Upload all external textures, presets, and asset files
Required - 3
Test that the add-on works without internet on a worker
Recommended - 4
Run a 1-frame test render on the farm before full submission
Recommended
Things To Watch Out For
- 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.
Common Mistakes
- Forgetting to upload local assets or helper files, causing incorrect renders on the farm.
- Assuming the add-on will work without internet access on a worker without testing first.
Recommended Workflow
- Open the scene in desktop Blender and run any interactive setup steps.
- Save the file and validate a small background render locally.
- Test a short render on the farm before scaling up to a full job.
Worker Node Setup
For render farm administrators: what each render node needs to run this add-on.
Install the same version of Render Profiler on all workers. Ensure all external files and assets are uploaded to avoid missing data during rendering.
More Context
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.
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.
