Heightfield - Distance Mask

[gestoryscht]

Hi guys,

I wonder, is it possible to generate distance fields out of heightfield masks?

I want to create an art directable island and whenever I blur the mask, obviously the the initial shape cannot be maintained.

It get's ...washed out. 

For big islands that's no problem I think, but small islands are tricky, because there is no island left after smoothing

So I wonder, is there an easy fix for this using distance fields (like in Substance)?

That's the default blur, but as you can see, the blur enters also the inside of the selection. 

Think more of texture dilation. The original shape is untouched and the dilation gets added.

float m = @mask;
m = m*10;
m = clamp(m,0,1);
@mask = m;

plus play with expand COp  I learned something

In your screenshot, it looks exactly like I need it, but when downloading your hip, the results are different.
First of all, I get an error. The wrangle nodes contains a:

#include <volume.vfl>

When I remove this line, the error disappears and it kind of works ... but it just get sharper.
Is this a kind of compatibility error? Do I miss something in Houdini?

Anyway - thanks for your help so far

Responding for anyone else looking for this.

Use heighfield(mask) as input in an COP network. Do stuff. Output. Use as input in an Heightfield File SOP. Profit.
