I created some new models and just placing them in the scene with copy and paste , makes each new some totally new object not an instance.
If i change something in vertex color in one model it does not reflect in others models , so how to make some object an instancing ?
It is mandatory to use blueprints ?
Instancing in Blueprints is actually batching, where they get batched together as a single draw call, good for doing stuff like minecraft type games where you have many objects that are low-poly.
Instancing–where it only keeps one of an object in memory but allows you to place multiple copies–is done automatically, it will reference back to the object in the content browser.
