UnrealLearningKit Robotics course: Can't select items from viewport

Hi Guys,

I’m new to the unreal engine and at the moment learning a lot about it through the online courses available. I did the MyFirstHour project and absolutely loved it. Now I am getting into the second part of the learning kit about robotics and I came across some issues I seem not to understand.

The exercise asks to select the robot to adjust some of its parameters. I can’t select it in the viewport and the item labels in the outliner are shaded.

Here is a shot of the viewport:

Here is a shot of the outliner:

So I started looking around and found that the items in the same LearningKit project from the MyFirstHour Project did not have that issue.

Viewport of the MyFirstHour items:

You can see the arch being selected and also in available in the outliner:

I did not understand the problem so I tried some troubleshooting with the limited knowledge I have. From the MyFirstHour project we learned to migrate stuff to other projects. This is what I did and this is the result:

The robot blueprint is accepted and can be selected in the outliner

What am I missing here? Did I already forget something from the courses? :sweat_smile:

Would be nice to continue this course as I am trying to use unreal engine for digital twin simulation in the future (machines/robots).

Thanks for the help!

Much Love,

Hi Karel,

In the bottom right of your first image I see that your ‘Current Context’ is “Level” and then in your second image all of the grayed-out assets look to be in “Map_1-6_Challenge”

So go to Window → Levels and make sure that Map_1-6 is not ‘locked’.

Hope that helps, thanks for the thorough post with many images!

Hi ,

Thanks for the solution, if I understand this correctly the level is layered with different sublevels like reusable building blocks? The locking allows you to only work on the parts you want.

The outliner:

Cheers!

Glad to hear it,

I’m not sure exactly how it’s set up in the robotics project, but It would make sense to have one ‘level’ (with ground and plants) and then swap out sublevels based on what learning content you’d want to load ontop of it. More info in Level Streaming docs
