Missing corona .dll - cant delete

Does anyone know how to delete a missing corona dll from my scene?
Image of error attached.

I use 3ds max with vray.
When I import some models they bring with them corona dlls.
These dlls stay in the file as missing.
This is a real problem with the render farm I use as I need to message them every time to set the scene off manually.
This is happening up to 10 times a day and really slowing down my workflow.

Would be a great help.

Doesn’t the autodesk scene converter work, removing those?
EDIT: To be clear, the AD Scene Converter has a specific mode to remove leftover dl* from the scenes.
It is generally used to remove mentalRay custom attributes, but works with any attribute type, in theory.

It’s in 2014 so there’s no AD Scene Converter.
This old chestnut again. :rage:

Argh.
Ok, i guess you should be able to use a max 2018, f.e., and then resave the file as version 2014 (later max versions allow for up to 4 previous versions’ format resave).
Not quite sure which is the first version which has both the scene converter and the previous version save.
Have a go at any of the demos of max you can find between 2016 and 2018 (or later, and then you save the file twice to get to v2014). :stuck_out_tongue:

I used to use this. Not sure if it`ll work for Corona or not.

Just remember to save up afterwards in case of issues.
