Completly agree. this image below is the potential final result.Square.Top of nodes. Simply. Only the system for activate or desactivate the preview need a “Real discussion”
And btw @Kdaf are already submit a prototype for the node :
And it’s really perfect like that expect the icon for enable or disabled the preview.
But now you can dev a new “Material preview node” with a custom shape object preview like this one
one imput, one output and a menu bar for selecting the object like in shader preview
combine both, (Object selection with the preview) and you got a new node for a Material preview and not a texture preview…
I try to make a news mockup with all ideas… humm i post in few hours stay tuned.
