The screen space at the moment is only for the Webgl 2 AFAIK is not working with mobile. Any alternative I can look for? Thanks! ---

Says here that you can use WebGL1 with extensions [Use the Screen Space Reflections (SSR) post-process - Babylon.js Documentation](https://doc.babylonjs.com/how_to/using_screenspacereflectionspostprocess) under Prerequisite section ---

> [@Michael\_Prosser](#): > > with extensions Thank you for answering! However, I’m not quite sure. Can you elaborate on that? I could not find any extension for SSR. ---

Hi, you will likely have to do a custom integration for this - WEBGL Extensions can be explained a bit more here [Using WebGL extensions - Web APIs | MDN](https://developer.mozilla.org/en-US/docs/Web/API/WebGL_API/Using_Extensions) You can use one of the samples there and see in the console that this loads an object: `engine._gl.getExtension('OES_vertex_array_object');` I am not sure which you need to do this - just guessing based on selection. I would check the list here and see what makes the most sense [WebGL Extension Registry](https://www.khronos.org/registry/webgl/extensions/) Hope this helps ---

It might take a while to experiment with this. Thanks a lot. ---

The current code is already checking if the extension is available when in WebGL 1 mode. If SSR does not work for you, sadly that means the extension is not available on your device. ---
