Having a problem building the lighting.
Tried verifying the builds and using earlier and newer builds 4.24 and 4.23.
No luck. Have enough Memory 16GB and 100+ GB of space on mac.
Running iMac (Retina 5K, 27-inch, 2017) Catalina
Any ideas?
Noted that if you run the firewall it fails to build the lighting, but doesn’t crash the editor.
Without the firewall on it just crashes the editor. In both cases the computer keeps running.
Sometimes I think I’ve fixed it and then just now, I opened a new empty level in the same project that crashed and it also crashed.
Any ideas?
