what is this error and what does it mean?

4 unbuilt lighting objects, required?

It means you need to rebuild the lighting. Click the dropdown next to the compile button and you should see “Rebuild Lighting Only” or something to that effect.

thank you, very much for the help, i shall test it now.
Ok after editing the game from scratch and adding 1 prop, it claims that a lighting object is required, what could i be doing wrong here?
hmmm… tried rebuilding only the lighting, now there are no collisions with props. The player can walk straight through them.

Which collision do you use for your mesh and what happens when you rebuild everything :slight_smile:

i had to trash the project and start from scratch, but i used the props that came with unreal engine 4.

Oh come on i gave you a straight forward, honest answer…
