[Solved] Nothing is rendered in-game (with panel renderer from cph2019 demo project)

What I did:

1. Installed UIElements 0.10.0 via the package manager
2. Copied the Assets/UIERuntime folder from this repo (https://github.com/Unity-Technologies/UIElementsUniteCPH2019RuntimeDemo)
2. Opened the ui builder, added a new button and saved the ui
3. Right-clicked in the scene hierarchy and added uielements -> panel
4. Set the "Uxml" and "Unity Style Sheet" to the ones I created earlier
5. Pressed play

I would expect to see the button at this point, but nothing shows up and there are no error messages.

Am I missing a step?

I used Unity 2019.3.0f3. I also tried with version UIBuilder 0.9.0, but it made no difference.

 

Add "Default.uss" from the UIERuntime folder to the Unity Style Sheet field and not the one you created.

 

Ah, that did the trick Thanks!
