[BUG] Building Lighting in OS X Editor stays at 0% indefinitely when Lightmass is blocked by firewall

Directional lighting is supported on Mobile actually. You can only have one though, as it can be expensive, and it has to be set to Static or Stationary. Take a look over our Mobile Development documentation to get a better understanding of the limitations when developing for mobile.

Mobile Development - Lighting for Mobile Platforms

Point lights and Spot Lights only support Static mobility types, which means if you are spawning your lighting in at runtime, you are going to have issues as these need to be baked using lightmass.

Could you provide me with some screenshots or your scene?

Thank you,

Still experiencing this issue…

OS X 10.11.5

UE: 4.12.3-3013449+++UE4+Release-4.12

Tried with following configurations:

• Firewall off

• Firewall on, exceptions for UE4Editor and UnrealLightmass;

  • Automatically signed… ON / Stealth mode OFF and ON

  • Automatically signed… OFF / Stealth mode OFF and ON

… and still can’t get past 0% on the build for lighting.

Any news regarding this?

You wouldn’t happen to have Avast Mac Security 2015 installed on your machine?

We do have a software conflict with Swarm Agent and Avast Mac Security 2015. Perhaps this is what is causing your issue?

Software Conflicts

Have you attempted to uninstall and re-install the engine?

Let me know if you have further questions or need additional assistance.

Cheers,

No anti-virus software installed, but I do have Freedome VPN. I did try all configurations with the VPN off, though, and still lags at 0%.

And yes, I had to uninstall and reinstall due to another issue, which didn’t resolve either (I’ll post a separate thread regarding that one later today).

If you need to know hardware here’s a screenshot, but I doubt that this setup couldn’t handle such a task as building some lighting.

UPDATE:
I finally managed to get the lighting to build, and it seems like the issue was with Freedome VPN, after all. After restarting the computer, I turned off Freedome and launched UE4 Editor, after which the build ran with no issues. Still verified that this was the issue by turning on Freedome, and alas the build stayed at 0%, and turning it off again made the build work again. Not sure why this didn’t work the first time around, but at least now it works fine (as long as the VPN is off).

This was actually fixed a few builds ago but is back again. I added a dual boot to my machine and use Windows for u4e and ut now. I was going to go back to Mac osx for it but alas the problem has returned.

Please check the update to my comment, the issue was with Freedome VPN after all. Mild inconvenience, but I’ll have to live with that for now.
