callback error related to Krakatoa

MAXScript Callback script Exception:
– Unable to convert: (prop KCM_CA ) to type: String <<

I got this error when I save.
Any idea?

Never seen this before.

KCM_CA is the name of the Custom Attributes paramblock created by Magma modifiers when exposing parameters to the Modifier Panel.
However, the error message might be coming from a callback that is not part of Krakatoa.

Try this:

  • Open the MAXScript Listener.
  • Delete all the text in the bottom pane.
  • In the top (pink) pane, type in
callbacks.show()
  • Send me (or post here) the output so we can look through the definitions and see if we can figure out which callback the error comes from…

Do you have any Magma modifiers or other Magma-based objects with exposed parameters?
