Missing Mental Ray DLLs

(1/1)

LorenzoS:
Hi all,
i have this message opening all files with max 2022 (see attachment).
Corona version: 7 (DailyBuild May 14 2021).
In max 2020 no problem.

Thank you

TomG:
Just means there is some MentalRay material / shader in the scene, which was removed from Max at some point (2021 at a guess). You can ignore the message in general, or use the Max Scene Converter to remove obsolete materials. Usually, the MentalRay material was not actually applied to any object and is just "stuck" there in the scene, so everything will render fine. If there is in fact a MentalRay material used first a) Why on earth...??!! and b) I guess it would fail to render and be red unsupported material or black for no material, in which case just build a new Corona Material for it :)

TomG:
(and btw that's nothing to do with Corona, it's a Max error message / warning dialog - you'd get this error on a scene using any render engine including native Max ones, if there was anything MentalRay in the scene).

Please try this:

I think there are also 3rd party scripts which can prevent this from popping up.

LorenzoS:
