Thank you for the advice, I’ll try the DDC clearing and static directional light since I don’t believe I changed the mobility settings when I was testing. Again, the project’s lighting built correctly on the Windows version, so it seems to be an issue with transferring the project to Mac. We did the transfer so that iOS development could continue in parallel to Android development, and also to develop the production pipeline for future Windows/OSX games.
Screenshots won’t be very helpful since again, everything (including all mesh) is spawned in. It’s a space game, so the eternal darkness of a blank project is the background.
