Solved terrain painter doesnt paint in a specific spot

hello, im making my first map for beamng and i am a beginner in map making
im painting with the terrain painter in the world editor to plan where i will place the roads, however i stumbled upon this spot on the map where it seems impossible to paint on
i would REALLY appreciate if someone could help me, thank you

 

back once again, i found another spot that is unpaintable with the terrain painter, how do i fix this?

 

At a guess, it is perfectly flat there, and your minimum of 0.8 gradient is stopping it.

 

i tried increasing the minimum but it still wont paint on the area thank you for the guess though

oh wait, i tried setting the minimum to 0.3 and it kind of started to paint, but it still isnt the best, ill try setting it to 0.0
update: it works now!! thank you very much
