> **Render Stat display HDA** by **Vincent** — a quick test setup HDA: drop in some geo, set the camera viewport, set the frame range, render. Useful for quickly evaluating render stats (timings, RAM, samples) on a probe scene before committing to a full shot render.

# Workflow
1. **Geo Import** — bring in the test geometry.

2. **Set Camera Viewport** — point Houdini's view at the camera the HDA will render through.

3. **Set Frame Range** — pick the frames you want to time.

4. **Render** — kick off and read the render stats.

# When to Use
- **Render-time profiling** — time a probe shot before submitting to the farm.
- **Settings comparison** — A/B render the same scene with different render settings.
- **RAM estimation** — get a baseline RAM footprint before pinning to specific machines.
