Disable thumbnails update in Hypershade

With scene that have lots of thumbnails in the Hypershade, and you wish to disable that update to free the RAM
You can do the following, but please be aware that renderThumbnailUpdate is undoable, queryable, and NOT editable.

// Turns on thumbnail updates.
renderThumbnailUpdate true;

// Turns off thumbnail updates.
renderThumbnailUpdate false;
 

Toggle the updating of object thumbnails. These are visible in tools like the Attribute Editor and Hypershade. All thumbnails everywhere will not update to reflect changes to the object until this command is used to toggle to true.

Hi, its strange reading its not queriable. You can use renderThumbnailUpdate -q and it returns the state properly. Cheers, Szabolcs
