Hi guys, Greetings everyone! Is there a way to keep all faces of my mesh being rendered with alpha transparency? I already disabled backface culling, but as you can see in this playground [Babylon.js Playground](https://www.babylonjs-playground.com/#IXYHWT), it is hiding some internal faces depending on the camera angle of view. Rendering the frontal faces on internal mesh: ![image](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/2X/4/40f5b147e91e171adfba23522769e322c03e4d19.jpeg) Not rendering the frontal faces on internal mesh: ![image](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/2X/0/09097d3a22ef0d6a4a6efc5fa7376623eb8de0aa.jpeg) Is there a way to force rendering all the mesh faces, regardless of the camera angle, if I’m using alpha transparency? Thanks for helping!! ---

To me, it looks like you have a z-ordering issue. If each container doesn’t have to be composed of multiple meshes, I’d try merging the meshes to see if that fixes the problem.

Hi @adam thank you for responsing… unfortunately I need the meshes separated 😅 ---

You can try setting the alphaIndex for each mesh. [https://doc.babylonjs.com/resources/transparency\_and\_how\_meshes\_are\_rendered#alpha-index](https://doc.babylonjs.com/resources/transparency_and_how_meshes_are_rendered#alpha-index) ---

Thanks @adam I’ll try it ---

It is exactly what `separateCullingPass = true;` is sorting: [Transparency and How Meshes Are Rendered - Babylon.js Documentation](https://doc.babylonjs.com/resources/transparency_and_how_meshes_are_rendered#how-to) [https://www.babylonjs-playground.com/#IXYHWT#1](https://www.babylonjs-playground.com/#IXYHWT#1) ---

Hi @sebavan thanks for responding! I tried with separateCullingPass, but I had the same issue… as you can see in your playground: [https://www.babylonjs-playground.com/#IXYHWT#1](https://www.babylonjs-playground.com/#IXYHWT#1) Seeing from top: ![image](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/2X/9/9e7d795d6345c4d84e2702a0ec067450c6e7211c.jpeg) Seeing from bottom: ![image](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/2X/e/e2604eedd7f477520e7db020cd16ff5813617e6e.jpeg) The frontal faces of the internal mesh is hidden when seeing the scene from the bottom, although these faces come first to the POV, I believe… Thanks! ---

could you split the internal mesh as a separate one ? so that you could always render it first solving it all ? ---

@sebavan I think yes, I’ll try splitting these meshes! Thanks bro!!
