You can also choose where to check: all scenes or current scene/view_layer only.


Q: Render result is not what I intended

A: This addon does not detect all problems. Check is based on current frame and does not consider status of other frames.

Q: Check takes a long time

A: Complex file may take longer to check. Try to decrease check items from preference. Checking image paths on network locations may also take time.


If you find bugs or have an improvement, let me know in GitHub Issues or my Twitter. Thanks for using FinalCheck.
