Here’s a script that I wrote to quickly switch between display modes for VRay Proxies. I’m not experienced with writing maxscript, but I’ve been using it for about a month and its been very helpful. Works with groups and mixed selections. Any improvements are certainly welcome.

A few comments.

The functions you are calling are being defined in the global scope, this means that you can access the functions outside of the tool, this may be what you want to happen but the best practice is to keep the functions in the scope of the tool when possible, this stops peoples global names mixing with other tools.

The other thing you need to be aware of is if someone adds a modifier onto a vraymesh it changes the class from Vray_proxy to say Editable_mesh or editable_Poly, so the way around this is to query the baseObject property of each object (kind of like the shape node in maya).

Adjusted below.

A small typo: double “o.” :slight_smile:

Zip it, it’ll work.

out of curiosity: Say that, after you press one button to turn all objects to Preview Faces - you press the button to turn them all back to whatever they were.
Would a feature like this be doable?
If yes, where/how would all those object’s previews be temporary stored.
Or maybe, this could work only as long you dont unselect, ie once you unselect it forgets.

You can store it into either files, temporarily in memory, and so on.
It’s generally a true PITA to keep track though, because people will delete or rename the proxy after the list was compiled, or some other such thing, so the amount of checks to be done tendentially become far more code than the actual functions to store and retrieve the previous visibility state.
It can surely be done, though.
