Currently some of the errors related to a specific control or channel are reported in status indicators next to the control (for example, there are two between “Use Radius Channel” and “Randomize Radius by ID” in the Meshing rollout). More general errors are shown in the MAXScript Listener, where’s it’s very easy to miss them.
Is there some method you would like to indicate errors? Right now I’m considering a log window that pops up when an error occurs.
