Blender did not complete every requested render frame

Error message

Blender did not complete every requested render frame

What it means

Render verification in verify_render: Blender did not report FINISHED or one or more expected per-frame PNGs (turn_0001.png..turn_NNNN.png) is missing or empty, so the render is incomplete and unusable.

Solutions

1. Check Blender's console/log output for render errors before the failure
2. Freeze no longer needed — reduce frames or resolution and re-render to a new output
3. Verify disk space; zero-byte frames often mean a full disk

When it happens
