Is there must be a floor in the level?

Hi everyone ! :rolleyes:

I found that if I create an empty level and build lighting , the building will stop at 50%.
To find out why , I created a default level , and delete actors in that level one by one . And the conclusion is I must not delete the floor or replace it with the Shape_Cube mesh in the StarterContent .

Dose anyone know why there must be a floor ? And why the Shape_Cube mesh won't do ?

Thanks ! :)

I had the exact same issue a while ago. Took me some time to find out it’s because of the floor mesh…

And you can’t replace it with the cube mesh or the chair mesh . It’s so so weird.:confused:
