Can't clone AbstractMesh?

Questions
1

Hello, I’m trying to clone a hierarchy in which the root is an abstract mesh. But it seems the clone() method of AbstractMesh is not implemented. I’m using an AbstractMesh instead of a TransformNode as the root because I want to add a physics imposter to the root. Is there another way?

I would use a TransformNode and just cast it to AbstractMesh at the time of adding the impostor

I’m confused by this answer – TransformNode won’t have relevant methods like physicsImposter and getBoundingInfo, and doesn’t implement IPhysicsEnabledObject. I don’t think a cast will make it work.

Try using a Mesh for the root node instead, then you should be able to clone the whole hierarchy and the physics impostor all at once I think.

let rootNode = new BABYLON.Mesh("rootNode");

Just wanted to add on top of that, an AbstractMesh cannot be cloned:

Hello just checking in, was your question answered? @afarchy

Thanks, using a Mesh works. Are there any negative performance implications to using Mesh over AbstractMesh?

Not at all, the Mesh is intended to be the main construct to be used at all times :smiley:
