Regarding 1/, I think you are using 4.2: there’s a bug that has been corrected in 5.0. If you want to fix it for 4.2, see [Compiling Node Materials with Instances on Safari - #18 by Evgeni\_Popov](https://forum.babylonjs.com/t/compiling-node-materials-with-instances-on-safari/16054/18)

For 2/, you need to use `clone` instead of reloading the 2nd material, and pass `true` for the 2nd parameter to reuse the same effect. There’s also some code that needs to be added to make `NodeAttributeInjector` serializable (else `clone` won’t work):
