somehow I can not get the shading to look smooth (or to change at all for that matter) ![bag](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/2X/8/8ee5aef78fe0cbb638952f044247079774f6fbfd.jpeg) I have tried mesh.convertToFlatShadedMesh(); but there’s no difference. Are there any other ways to get rid of the shaded polygons? Or is there a way to adjust the phong angle in babylonjs? The model is deformed by using bones animation. And I think that causes the problem. Since I don’t know how to upload my model to a playground, it can be found here: [http://flomotion.nl/paperbag/](http://flomotion.nl/paperbag/) click next to play animation… ---

please create a playground 🙂 [https://doc.babylonjs.com/resources/external\_pg\_assets](https://doc.babylonjs.com/resources/external_pg_assets) if not possible, please include the inspector & babylon.max.js on your website it will be much easier to see what’s going on. ---

Ok, thank you. I managed to create a playground with embedded model: [https://www.babylonjs-playground.com/#KEY4S4#1](https://www.babylonjs-playground.com/#KEY4S4#1) ---

Hi @flomotion bumping the topic. Tough case to crack 🙂 I’m unsure what to do about it, but hopefully someone can solve it. ---

Bone-weighted meshes can be smoothed just like any other, so there must be some other issue somewhere. (Pro)/boolean sometimes creates weird artifacts, especially if you simply apply one smoothing group. Have you tried putting all the sides in their own smoothing groups? ---

Hi Raggar, Thanks for your reply. I did try to split the model into seperate planes. But strangely enough there was no difference at all. As if the polygons were still connected. I managed to solve the problem by using a specific shader. This was a lot of digging and trying. But it looks decent now. but if anyone knows how to fix this issue differently… That would be better. ---

Thanks for looking into this 😊
