Graphics card: NVIDIA GeForce RTX 3060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 536.23

Blender Version
Broken: version: 3.6.0 Beta, branch: blender-v3.6-release, commit date: 2023-06-21 21:04, hash: ae35861a64ca
Worked: 3.6.0 Alpha, branch: main, commit date: 2023-05-16 23:35, hash: c8b5b17d40c4

Caused by: 8a11f0f3a2

Short description of error
Split Edge node do not split edge lines to individual edges.

Exact steps for others to reproduce the error

  1. In Geometry Nodes:
    a. Add Mesh Line node.
    b. Add Split Edge node.
    c. Mesh Line -> Split Edge -> Group Output node.
  2. Apply modifier.
  3. Go to edit mode.
    Notice the loos vertices and the still connected edges.

As far as I could tell from the information provided by the viewer node, the Split edge node seemed to actually work (it results in 4 edges, 8 vertices for this simple test).

@emilian Vertices is not connected, there is just 4 connected edges and 3 dangling points.

In my case I found out the problem was comming from the "mesh to curve" node, it merges again the already splited vertices.

@JuanManuelLynch In your case, Edge Split node didn't splite edges at all. Mesh to Curve just delete dangling point.

@mod_moder Are you sure? In both versions I get same output from the split edges, 3 vertices go into the split edges node and 4 come out

Please apply the Edge Split node as modifier and go into edit mode

Correct, it doesn't split edges, but the fourth vertex is still being created.
