Access the egui_wgpu::RenderState after the app creation

[brunnerant]

Hello!

I am using eframe with the wgpu backend for custom rendering + UI on top of it. I have seen the example with the triangle and read the source code.

In the example, you create all the wgpu-related resources from the creation context, at the application startup. But is there a way to defer the creation of the resources to a later point in time ? I.e. since I plane to have several scenes, I want to only load the relevant one at any given point in time. In order for that to work, I would need to access the egui_wgpu::RenderState after the app creation, at the time where the scene is changing, for example. But I didn't find a way to do that reading the API. Do you know if that's possible ?

I hope my question is clear, and thank you for the great library!!
