i cant start a session bcause of a material but i delete it so idk what can i did
Hey Babaela_7.8,
Sometimes custom material references can get stuck in the HLOD.
If you have built HLODs before, test this by making a totally new HLOD layer in the Content Browser.
Right click, select World > New HLOD Layer
Don’t build or delete HLODs.
Open World Settings tab, then drag the new HLOD layer into the Default HLOD slot (or both slots if there)
Test this, does it let you launch ?
