Where can I find the material examples?

In earlier versions, there was a default map which contained quite a few material examples (used in this video) but I cannot find this on the marketplace anymore. Could someone please give me an idea where I can find this content?

Thanks!

Isn’t this just the starter content (see blog)?

Ah ok - my apologies. I’ve been trying to find the starter content with a workaround because creating new projects resulted in crashes. I turned insane for a while there I think. Will report back and mark as answer when confirmed.
