Can I use Unity provided example scene assets as an example of my shader package?

I’m almost finished implementing my shader package, but I need a somewhat detailed scene to make it look good. So my question is: Can I use the models/assets provided by unity in the example scenes(such as angrybots) and modify it as my example scene? I’m not trying to resell the assets, I just need a detailed scene as a showcase/example scene for my shader package(which I want to sell on unity store). I’ve been modeling for some time now, finished a few models but it’s still not close to completing a detailed scene.
And do you need unity pro in order to sell shader packages on unity store? Thank you.

You are free to use the Unity Assets in your project (as long as you don’t resell them). As for your other question, you do not need Unity Pro to sell assets on the Asset Store. Hope this helps!

From the Unity FAQ:

Can we use the code/art/assets in Unity Technologies’ example projects?

Yes, all assets in our tutorial and example projects may be used in both commercial and non-commercial use in Unity-based projects. The assets themselves may not be resold, however. Note that these assets are widely known in the games industry, so if you do use them in your titles it may be obvious that you re-used Unity assets.

what will happen if i sell examples provided by unity ??
