Dotted Points in Viewport

Recommended Posts

Hi guys, I'm totally a noob at Houdini here. I want to ask that usually when I want to choose some edges from my model, I have this dotted point as if they are not connected. In this scene, I use a group node to choose the edges with delete non-selected, then I applied blast node, then sort node by Y, and used the add node after that. It solved the problem, but I feel that there's a better way to solve this problem. Does anyone know what's the possible cause of this problem? I will provide the hip file in the following attachment. The geometry node is called "big_pillar". Thanks in advance!

The root cause of your problem is that Dissolve is not the right tool to create an open polygon from an open group of edges.

This is what is causing display problems for example: the primitive is there in Shaded mode, but it cannot be displayed because it's degenerate.

You can convince yourself of that by dropping a Carve SOP after this node; you will see that it's making a loop.

You can however use it with by extending the group to the back of the geo, but this is really contrived at this point

One easy solution would be: Boolean Shatter:surface / surface / generate AB-Seams, against a vertical grid..
