I want to paint over an object, like a stroke over the surface, but in the ways I have tried It didn't work.
In first place, I tried with the Annotation tool from the toolshelf. It works well but It didn't stick onto the surface (when the object moved, the stroke stayed in place).
In second place, I tried adding a new blank grease pencil and setting its parent to the object I want to draw onto. Entered in Draw mode and set Stroke Placement (surface). This didn't work because the stroke was not sticking right onto the surface.
In last place, I tried to use Vertex Paint mode, and it works but I can't see the strokes in Object Mode. I tried some ways:
https://blenderartists.org/t/seeing-vertex-paint-in-object-mode/1158358 I don't have Vertex, only Single, Material, Object, Random, Texture. Blender v2.80.55.
When I paint in vertex paint, and after I switch back to object mode it does not show the paint Not the same Blender version. I can't find Texture mode, only Wireframe, Solid, LookDev, Rendered.
