Export problem

[Alexey_Galanen]

I installed a blender plugin, I created a shape that looks like a house, but that's not the point. I attach a screenshot of the export error. https://imgur.com/a/nW9JybM
I've been agonizing about this mistake for a whole day now. Tell me how to solve it.

You need to make aforementioned object into an SCS Root Object.

1. Click your model.
2. Shift + A > SCS Object > Root Object.

Now, on the right hand side (the list of tabs) Click "object" it's the orange box and expand "SCS Objects" drop down. It should all be set.

AFAIK that's the correct way. Then export using the Output Properties tab on the right hand side tab.

Thank you, but how do I rename it? Can you show a screenshot or video on a regular cube?

On your first screenshot you have, at the top right an object named "Cube" it it becomes "game_object" double click it to rename.
