Following the tutorial that I found here but I ended up with this error: there aren’t any strokes attached to the objects.
This is my step that I did as explained in the tutorial.
- Added the Spehre and added the Subdivision Surface.
- Added the Plane, into edit mode and remove the Vertices.
- Added the new GPencil.
- Stroke Placement into Surface.
- Added (Drawn) the lines on the Sphere surfaces.
And when I pressed the add Surface in BSurfaces tab I got the error.
I’m using Blender 2.78c.
