Hello everyone,
Many thanks for the help you've been giving me on the past few days.

I now face this problem: I have got a dop simulation which runs fine, and I am using a dopimport node to import the data in a geometry node which works fine. Problem is, I want to apply a polybevel on that geometry, but it doesn't seem to do anything. Other nodes - such as subdivide, color, polyExtrude - runs fine but not the bevel, as you can see from the pictures. Doesn't work both on the dopimport node or cached geometry. Any reason why this would happen?

Many thanks. I have attached a .bgeo frame of my geometry. I've tried both on Houdini 12.5 and 12.1 (both installed on my Uni computers) without success.

There seems to be something wrong with your geometry.
All faces are not connected with any other faces.
If you can tell us how you generating the fracture geometry maybe someone can help.
or just post HIP file.

As a debug workflow I would get 1 piece to work correctly and use a test bed > what are the normals doing ?
