solved [SOLVED] own mesh crashes website if merged

[Turiim]

Hello Babylon Fans,

I was hoping you all would be able to help.  I am not sure what I am doing wrong, but I am trying to merge  a custom mesh and an instance of that custom mesh. Then I uncommented the merging function my whole website crashed.

Here is an example:

Hello,

"scene.getMeshesByTags("merge")" ==> this returns no meshes

Obviously the point @Deltakosh made is one important issue why it does not work.

Swapping for clone rather than instance and putting in the two meshes as an array into mergeMeshes works https://playground.babylonjs.com/#JVQXIM#2 

However in the above playground that works and swap back clone to createInstance then the PG does indeed crash. I am guessing but probably something recursive is happening because of the way the geometry of instances is stored.

Not just custom meshes either, this PG with clones is OK https://playground.babylonjs.com/#JVQXIM#3 but change from clone to instance and my laptop locked up until I could remove the PG and then had to wait.

This appears to have been solved in the past but looks like some changes somewhere have reinstated it.

Yep I forgot to mention it: instances cannot be merge as they are reference to a root mesh. So it kind of like trying to merge yourself with yourself

Hello,

sorry, I forgot to change "scene.getMeshesByTags("merge")" to [mesh1, mesh1_instance]....

Ahh ok, I will just use the cloning function then.

 

Thanks for the responses
