Some kind of race condition in skybox routine

[pillowtrucker]

Sometimes, the skybox routine will crash if the files don't load fast enough. I checked if it's not my code doing something silly, but it seems that the rend3 routine itself is unreliable. It is possible for this:

    lock(skybox_routine).set_background_texture(Some(handle));

to set the handle to Some(_) after getting it from the renderer, but then the crash happens when skybox_routine.evaluate calls

    pub fn get_view(&self, handle: RawResourceHandle<T>) -> &TextureView {
        &self.data[handle.idx].as_ref().unwrap().view
    }
