Windows 10, NVidia GTX 780
Broken: 2.76, 2.78 RC1, 2.78 RC2
Short description of error
When running the x3d exporter with Triangulate enabled some of the vertices in the mesh get saved multiple times resulting in duplicate vertices and edges. The result is a "cut" in the surface that can be opened up by moving one of the duplicate vertices or edges.
The attached screenshot shows the original mesh (to the left, with one of the edges that get duplicated selected) and the mesh after exporting and then reimporting the mesh with Triangulate enabled (to the right) with the "cut" opened to show which edges are being duplicated.
Exact steps for others to reproduce the error
- Open the .blend file.
- Export to .x3d, with Triangulate enabled
- Reimport the .x3d file into blender or open it in any other software that supports .x3d files.
