It's turtles all the way down. You can replace the renderer wholesale, or strip out the top, middle, and/or low level abstractions. You choose how much meat you want stripped off from the bones. It's not that well-documented (something I want to address soon), but IMO it lives up to Bevy's reputation of modularity.

For a comparison with Unity, it's equivalent to the scriptable render pipeline, but abandoning the default one doesn't mean you need to write your own pipeline from the ground up.

That sounds very promising. Could you point me the right direction on how to learn about Bevy's render pipeline? I've had some rather superficial understanding of Bevy (mostly just by following along the examples on the official site)

And what's the equivalance of Unity's Frame Debugger? Since Bevy doesn't have a GUI editor yet, I guess the answer is just to use Render Doc?

The best 10,000ft view that doesn't just point you at the code itself is probably https://bevy-cheatbook.github.io/gpu/intro.html. If you need finer details, you'll need to read the code itself, or ask in the #rendering(-dev) channels on the Discord.

Again, I'm not happy with the state of public documentation for this, but as seen with this release, it's still heavily in flux. I don't think we've had a single release since 0.5 that hasn't made major architectural changes of some kind.

Yep, just use RenderDoc right now. I don't think we'll have a good solution for this for a long while, since building one of those from the ground up is a huge undertaking.

I don't mind to eventually read the code. I've learned how to use SRP by reading URP code anyway, because Unity's document in this regard isn't particularly great either ;p (of course my Rust fluency is still not at the same level of my C#).

Thank you very much for the answer!
