Map editor. My map is blackened when I test it

@jip
Yes the bug is only present with certain positioning of the camera on the map as well as a certain degree of zoom.

I think the bug is water related. when I remove it from the whole map the bug disappears

I have a friend who is also trying to create his water map and he has the same problems as me

Edit: just to be sure, the map editor names it: fafmapeditor_alpha_v0703?

That is the correct version. I can't help you further - maybe @MadMax can.

okay np, thanks you !

upload the map or send me the file on discord

wish i could help i've seen this bug before never been able to fix it tho short of exporting every thing then importing back to a new map

does it only happen with this map as it looks suspiciously like a ui mod bug

Thanks for your answers,
I will try to export / import the map later.

When I do my tests, I directly use the "test map" button on the editor. Are mods installed from the FAF client activated when I play from the base game?
I only have 2 UI mods active simultaneously, Nvidia fix and Philip Crofts soundtrack or Total Annihilation Music.

from 2014 but maybe what you are searching for:

[...] the maps break (huge black area) when the height range in a map is too large.

don't use the test map button in the editor it can cause issues either test through the client or the offline exe found at

C:\ProgramData\FAForever\bin\ForgedAlliance.exe

Okay, I won't use the test map again in the future.

I solved my problem. I cut the map into a few parts that I removed one by one until the time to identify the problematic places. I confirm that the problem is related to the heightmap. Somes mountains had to be completely removed and impossible to add new ones to these places without making the bug reappear. It's a bit annoying but at least I'll stop struggling on that xD

Thank you all for your help !
