Troubleshoot a failed bake

Find the cause of a failed bake in a few calm steps, instead of changing several settings at once.

You will

The cause of a failure found and fixed, or a report ready for support.

Before you start
  • A bake that failed with a CNX code.

Step by step

  1. Read the first error

    Note the exact CNX code and message in the Bake Window. The first error is the one that matters.

  2. Look up the code

    Find the code in the error codes list. It tells you the cause and the first thing to try.

  3. Check the solver

    In the Cloth neXt preferences, click Run Health Check. If it fails, fix that before anything else.

  4. Check the scene

    Click Run Scene Health Check. It checks geometry, solver readiness and storage.

  5. Make the scene smaller

    Use a short range and hide unrelated objects until the failure is isolated. Then add things back one at a time.

  6. Ask for help with a report

    If you are stuck, use Export Privacy-Safe Report and send it to PolyWorks support with the CNX code.

Check the result

The short test bakes again, then the full shot.

If something goes wrong

Cloth passes through objects
Check collider motion, surface offset, collision gap and scene scale before changing advanced solver values.
The bake runs out of memory
Use a collision cage or proxy, reduce collider samples, and keep memory safety on.
