Maxwell Render | Official public forum

There used to be a menu for selecting which one of the MXM maps was selected as the viewport preview map in Max.

How is that done now?

The exact same way you would do it if it were a standard material. Click on the map in the Maxwell rollout and click the checker blue and white cube that tells it to display in the viewport.

I see. Nice enough. I only wish this setting was preserved from the last version, now when I open an old model all previews are turned to grey and I have to go through the entire XRef hierarchy and reselect viewport bitmaps...
