I'm trying to use the solidify modifier to extrude a vertex group like the image below
But when I try the result is a sloped, rather than a rimmed
One of the causes could be the weight painting for the vertex group is a gradient.
Is there any way to get a slope rather than a rim?
I have found Geometry Nodes can be used to get 90% of what I want. The following is a simple Geometry Node setup which will do an extrude without a slope:
Seems to work well with more complex shapes.
It's possible to have multiple vertex groups on the same object with different heights.
There still are some problems:
I don't know how to keep a face out of the vertex group if all the faces surounding it are part of the vertex group.
Vexrtices which are part of two vertex groups with different heights behave strangely
Any help on the above two problems would be great.
