Do not re-render material previews when changing from production to active shade mode

Is it possible or is this a max thing?

If I switch from Production to RT or vice versa (Max 2014) lagging starts since it re-renders all the material previews. Can this be done on-demand if I change a material and not all of them?

It’s a 3ds Max thing; it automatically recalculates the material editor when switching renderers. You can submit a request to Autodesk to change that.

Thanks for the clarification - fast as always.
