Hi found error using 3.0 version on android and incremental loading

Galaxy Tab 3 

Android version 4.4.2

Works fine with babylonjs 2.5.

 

Will try to investigate more

Found source of error.

const copy = mesh.createInstance(`copy_${current}`);
            copy.parent = mesh.parent;
            copy.setAbsolutePosition(mesh.getAbsolutePosition());
            copy.rotation = mesh.rotation.clone();

I copied loaded mesh 30x times. Looks like using incremental loading crush something in createInstance. 

Could be related to:

Should I wait before creating instances? Right now I do it on SceneLoader callback.

Yep as you are using incremental download you have to wait for mesh.isReady() before creating the instance

@Deltakosh Thanks for feedback. I should just check it inside registerBeforeRender ?

correct
