how do i separate the objects in 3d object scene layer as individuals in unity

[RupaLNU]

Hi, I'm working with ArcGIS sdk for Unity and I have uploaded the 3D object scene layer in Unity. At the moment these are just blocks and not houses. I'm trying to change the texture to houses but they are all selected as one object, which makes it difficult. Is there a way to convert them into individual objects and then add texture to them to make them look like houses?

Hello, you could load the 3D object scene layer and change the texture of each individual object in ArcGIS Pro.

When importing layers from ArcGIS Online into Unity, I encounter the problem that some objects are not independent, but randomly composed of different objects. I'm guessing this could be due to data format, import settings, or other factors. But I still haven't solved it. I don't know if you solved this problem. Is there any good way?
