Trying to create instance, .babylon assets work but .gltf doesn't. Why? (see PG)

This pg. I try to copy 3 dragons with mesh.createInstance, but it doesn't work.

However if you comment out line 16 and uncomment either line 14 (skull) or line 15 (tree), both work.

Is it because dragon is a .gltf file and tree/skull are .babylon file? How do I work with .gltf files?

use clone

CreateInstance does not support hierarchy, only the current mesh as explained in more detailed here: 

 

You might need to follow the same solution by creating instances for the entire tree or the art you d like (probably the mesh containing render data) and reparent them.

my questions followed:

1. As shown in this PG, my goal is to show dragon one by one, walking towards you, so I used setInterval, is it a good way to do it and if not, any alternatives?

2. I can't seem to hide the original dragon, if I dispose it, nothing will be cloned, but if I just set its isVisible = false, doesn't work.

3. How do I play / stop the animation of the cloned dragons?  I don't know where to find the animation instance to play.

1. setInterval works. You can also use promises and use Tools.DelayAsync, but I don't think that will be much easier.
2. isVisible does not affect the children. You can use setEnabled(false) for this purpose.
3. This one is trickier. I don't think there is a way to do this right now without walking the mesh hierarchy. I've filed an issue.
