Bug Brush Mask Filter Bug when painting Textures

I tried to paint snow on top of the mountain. However the brush seemed to paint everywhere except when the Concavity Strength wasn't 1. Or almost 1. Should it paint outside the orange area?

The orange preview part seems to be buggy, maybe that's related?



My settings (click to enlarge):

 

Yes, 3.0.1-preview. Here's a quick animated gif. I can upload a youtube vid if you prefer. I could also file a bug report, it's just a simple scene:

 

By the way, when I lower the Feature Size parameter I kind of get where I want to be, independent of the orange preview brush which seems to be a bug. I also have to modify the Remap Curve of which I have absolutely no idea how it works. And honestly - and that sounds harsh - I don't want to read a manual for simply painting snow into the concave parts of mountain.

So the main problem I see: It's super powerful stuff, definitely capable to do what I want, but not user friendly at all. Or rather not intuitive.

 

Done, case id 1289172, case name "Terrain Concavity Issues"

I'm getting there with the settings, but a question in order to understand this: Should it paint only in the orange parts of the brush or outside as well. Now it would paint outside as well, even when there's nothing orange inside the brush:

 

In addition to that, same version as in the bug report, the strength in Set Height seems to be broken. I'm pressing CTRL here to lower the terrain and I have absolutely no idea what the Concavity Brush Mask Filter would do here. I'd expect it to lower only concave parts then.

Either way, even at a strength of 0.063 I can move entire mountains By the way, I had the strength range increased to 10 before and then set it back to 1 in the same session. Maybe that's stored somewhere and now it takes 0.63 from range of 0 to 1? But that's just guesswork, I didn't check the code yet.

 

Ooops, apologies, the "Raise or Lower Terrain" Tool

 

It was accepted as official bug:

Hopefully fixed soon.
