I’ve noticed something odd and have no clue why it happens.
I’ll create a collection that includes a curve object and make the collection an asset. If I use the asset and make instances real, it creates a duplicate of the curve objects in the same space as the original.
???
I tried a new scene, added curve > m > new collection > right click on collection in outliner > mark as asset > dragged asset into scene > make instances real > no copy, just the two that I made.
blender 3.3.1
I should have noted that I was using the asset in the same file that I created it in. Which probably has something to do with it.
That’s what I did.
