Solution

• Brings back animated_material example but cranked up and with shadows

Code looks good, stress test runs (and stresses both me and my machine).

I don't understand why 3d_scene got changed as part of this PR though: I think that's just a git mistake?

[atlv24]

Whoops good catch. That was leftovers from testing a bug in bevy main that im gonna be opening an issue for soon

Since this is a stress test this should probably be configurable using argh. Something like bevymark.

Maybe giving it a specific amount would be more useful though.

If you're making it configurable with argh, please copy the cfg blocks from the other stress tests using it (eg. many_cubes) as argh::from_env() panics in wasm.

Other than the cli config suggestion LGTM

using the helmet instead of a pbrbundle means you're also adding hierarchy and complex meshes to the stress test

it also means we don't have direct control of the material and can't try easily if it's because one of the property of it

I would prefer to use a PbrBundle as it makes a more focused stress test, and it wouldn't need the make_materials_unique system

[alice-i-cecile]

Hmm, I think I agree with this analysis. It would be better to be able to properly isolate the effects here.
