Everything I see about using a height field paint node, involves feeding it into a HF Noise node, or similar. Is there a way to simply offset your painted mask times 10, 100, etc? So that it offsets the height field exactly the max amount, times the percentage of mask you paint?

you can for example do Heightfield Wrangle:

or Heightfield Combine Layers:
- Destination: height
- Source: mask
- Operation: Add | Scale + Add
- Scale: your height offset amount

you can for example do Heightfield Wrangle:

@height += f@mask * chf("amount");

or Heightfield Combine Layers:
- Destination: height
- Source: mask
- Operation: Add | Scale + Add
- Scale: your height offset amount

Oh awesome, I never would've thought of the Combine Layers node, thanks so much!
