Been using the past 3 bleeding edge versions, and in neither was any option other than normal build available.
Just grayed out and I can't figure out how to enable or select it.
On one example map, I managed to make a tiled build somehow (don't ask me what I did….), but once I switched to normal build, the option to return to tiled build was once again grayed out.
Even tried opening a simple terrain from the non-bleeding edge version with tiled output already set up in the build options, but it also only allows normal build.
Am I missing something to get tiled builds to work?
