Hi,
I am going crazy here, spending many days trying to solve this, and would greatly appreciate any assistance please.
I have a DEM heightfield of an island. This comes with a flat area where the ocean was. I was hoping to remove this, so that my lake/ocean is deeper. Screenshot attached.
Basically, anything that has an altitude of 0.1m I would like to mask off/remove.
Many thanks.
I don't exactly know how it works with dem and heightfield,but you could try adding a surface shader (or distribution shader), set an altitude, a fuzzy zone, and lower by offset (and/or smooth).
I've never worked with a DEM but if it's the same as any other heightfield you should be able to adjust the height with a Height Adjust Vertical node
with the Add Height adjustment, this will raise or lower your heightfield.
I'm actually working on the example I've attached.
Yes, very good solution!

Hi,
thanks so much!
Yes this solution (surface layer with negative dispalcement) worked. Many thanks.
Note that I already had a 'heightfield adjust vertical' node. ALl it was doing was raising the entire heightfield, which included the area I wanted removed. I think the
Digital Elevation Model must have included the ocean.
