Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
System Information
Arch Linux
Blender Version
Broken: GPencil_EditStrokes branch (as of 4c54390), self-built
Short description of error
If you have a grease pencil layer and you create a new scene using Full Copy, the second scene doesn't use a new copy of that layer. Instead it points to the original grease pencil layer. The effect of this is that any edits to that grease pencil layer, including animation, shows up in both scenes. There doesn't seem to be a way to make the grease pencil layer single user for that scene (the button is there, it just doesn't work).
Exact steps for others to reproduce the error
Changed status to: 'Open'
Added subscriber: @JasonvanGumster
NOTE: Will be fixed in Strokes Editing branch
Todos:
Fix up BKE_scene_copy() to make changes to GP Datablocks
Fix up the GP datablock copying code in gpencil.c - This is actually dangerous code, since it doesn't work well if there are multiple users of a GP datablock, OR if the datablock has ID props
Oops - As a little dev note for future reference, I just found out that the datablock duplicate code is now used for undo too, which puts a bit of a spanner into the works for the above plan!
