Terrain stamp, negative stamp (remove material)

I might have missed how to do this, but I often want the ability to stamp a hole onto terrain.

Would be nice to have the brush remove material according to the brush if you hold shift.

EDIT: A few other thoughts I had which would be nice:

• The ability to toggle between additive stamping and "max" stamping. When you stamp, it takes whatever heights you are current over and adds your stamp to it. It would be nice for the stamp to "take whichever height is the greatest between the existing terrain and the stamp". That way if you want to overlap a stamp multiple times, you can do so without getting spikes where the stamps overlap.
• The ability to rotate stamps (if possible, not sure how hard that would be under the hood). I know I can always use another program to edit but the speed for native rotation in unity would be great.

 

@ChrisTchou
Is there a modifier or alternative for mousewheel? our artist doesn't actually have a mouse, just wacom.

 

Yes we need native wacom pressure support in the terrian tools

in the meantime

have a go with this tool

https://assetstore.unity.com/packages/tools/terrain/terrain-pressure-paint-deprecated-30384

 

I dont need that. I need alternatives to the missing mouse wheel. I already have that asset and am tired of it failing to work half the time.

 

Ow I see what you mean, no wheel on the pen

 

Yep I don't use the pen with Unity but those who do often don't actually even have a mouse (artists are a funny bunch).

[ ] for brush size would be a great start (photoshop and clones use it...)

 

In Maya there are many tools that use the pen.
Terrain painting with pressure, texture painting, vertex painting, vertex color painting, vertex weight painting for bones etc.

And they have pressure and tilt and 3 buttons
I may classify as one of the funny bunch.
