Description

System Information
Mac OS X, MacBookPro 2010, NVIDIA GeForce 320M 256MB

Blender Version
Broken: 2.78b
Worked: (optional)

Short description of error
Cmd C = Copying Mesh to Buffer and pasting it into another Blend actually change the vertex index order. This should not happen I think.

Exact steps for others to reproduce the error

  • Select some objects
  • Copy Cmd C or Ctrl C
  • Paste Cmd V or Ctrl V in any Blend file
  • The vertex is out of order, basically obvious when Join as Shapekeys.

Have you tried 2.78c and the latest builds from https://builder.blender.org/download/?

Can you provide a .blend and exact steps to reproduce the error? I couldn't find any issues using Join as Shapes with pasted objects.

Ok, I might be wrong with Buffer object copy paste shuffled the index... it is more likely that the Default Blender Box index order does not match Blender "Create New Box" object. I tested with Shape Key and occassionally I am getting this weird Index Shuffle. Maybe it's just Blender Default Cube index needs to match the box creation. It's small details but might confuse Blender users.

Maybe for Blender 2.79 the default Cube / Box index matches the Box generated?

Also seeing our versioning_defaults file, might be good occasion to update that startup binary indeed. @Sergey Sharybin (sergey), @Campbell Barton (campbellbarton), you guys know how to do that correctly iirc?

Note that T51111 show that the weird 'zig-zag' pattern of Add -> Cube geometry can cause some unexpected side effects… Not sure why added cube get that geometry (vertex ordering), instead of more conventional one like Default cube?

Could we simply replace the default cube in startup.blend.c?

My mistake, it was not a duplicate

I don't think this is a bug. The default cube does not have to match the cube created by operators.
And the user can always update the startup if they prefer.
Closing.
