Doing tree shaking I have errors with Nodematerials import. ![image](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/3X/8/0/807c1048f84141807c131ae22c591fa7e2671f88.png) ![image](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/3X/e/3/e397f254d6f4b0bebe1d5400b20fcc25fe11c578.png) (Of course, it works when doing `import * as BABYLON from "@babylonjs/core";` There was the thread - [Importing NodeMaterial with tree shaking](https://forum.babylonjs.com/t/importing-nodematerial-with-tree-shaking/24828) with similar issues, but still I am not able to make it work in any import combinations which I’ve tried. Could anybody provide the right import statement for Nodematerial? ---

You probably need to import all the blocks that are usefull in your serialization for side effects. or better import { NodeMaterial } as BABYLON from “@babylonjs/core/Materials/Node”; to have all the node mat side effects. ---

This one I tried already: ```auto import { NodeMaterial } from "@babylonjs/core/Materials/Node"; ``` and it gives the next error: ![image](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/3X/9/f/9f696715f6b3b42aebbe9067c1e05b733ad77e17.png) ---

import { NodeMaterial } from “@babylonjs/core/Materials/Node”; should import them all so it might not be this unfortunately ☹ and to know the nodes, it would be all the ones in the material you are trying to parse so kind of hard to really go deep on this front. ---
