Skin POP not skinning things

Bugs
1

I have a line POP and I’m just making a closed triangle shape using that and plugging that into a skin POP. What’s odd is that the info says prims are being created but I don’t actually see anything being generated. I don’t think I’m doing anything wrong here and I’d expect the skin to just find the three points and build a face from them. Am I missing something or is this a bug?

Hello @Ennui

The Skin POP requires a multi-dimensional arrangement of points (such as rows and columns) to connect them into a mesh of triangles or quads.

In your case, because you are using a single line POP, your data only has one dimension containing 3 points.

To fix this, you have two options depending on what you are trying to build:

  • If you want a solid 2D triangle face: The Skin POP isn’t the right tool. Instead, you can look at using a Triangulate POP to explicitly build a face from those coordinates.
  • If you want to use the Skin POP: You need to feed it a multi-dimension arrangement. For example, if you copy that line to create a second set of points, the Skin POP will happily bridge the gap between the two dimensions to form your mesh.

This works. It’d be nice if when the skin POP failed because the geometry is 1 dimension if it could throw a warning suggest looking at the triangulate. At the moment you just see nothing in the viewer with no warning or error so it feels like it’s broken. The triangulate is working beautifully even with odd shapes though.
