[1.8.X] Orbital Survey Plus v2.3.6 in Add-on Releases Posted October 9 · Edited October 9 by Wheffle @Spricigo I try to check this thread periodically, although I guess it took me a month to notice your comment. Sorry about that. The option to view the biome overlay won't show up unless you have scanned at least a little bit of the planet, or the option for "biome overlay does not require scan" is checked. If one of those things is true and you still don't see it, then it may be a bug and let me know. Edit: Also make sure you have the planet focused in the map view, not the ship. I chose to have OSP follow the same rules as the stock overlay buttons, in that they won't show up unless you focus the actual planet. Also, I believe I have only tested OSP up to 1.8, so there is a small chance that any newer versions of KSP have introduced a bug. It's probably about time for me to test in newer versions, I've just been hanging around in 1.8 for my own current playthrough so I haven't gotten around to it.
