Hey everyone,

Hope to get some help with this issue. I’m trying to create VR project and when I name it and try and open, Unreal immediately crashes. I’m on a Mac Studio M2 Max chip, 64gb ram and running on Sonoma. Below is the report I get –

Same here, still on Ventura 13.6. Crash reported

You may need to set r.ForwardShading to false in your DefaultEngine.ini

You can open your DefaultEngine.ini up by right -clicking the file and opening it with a text editor.

My 26th line of this file says
r.ForwardShading=True

Try setting it to: r.ForwardShading= False

Save the file.
Relaunch Unreal Engine and open the project.
