Sorry if question may be dumb, as I’m just a few hours trying blender.
What I wanted to do is add an image to a sphere and then unslice it afterwards.
Have seen a lot of fine working solutions using sphere and Unwrap->Sphere Projection.
However this cuts the slices in a way, which is unsuitable for what I wanted.
Goal would be to recreate a real 3D Object afterwards (e.g. inflatable water-balloon).
So the slices should look somehow like this (which I managed by adding seams, where needed):
@Korchy thank you for your suggestion. However using this method, I don’t seem to be able to get the unwrapped image onto the slices as shown in the image in the lower left corner:
@JohnVV, thanks for pointing me to this direction. Haven’t tried using netpbm for this yet. Did some experiments using Mathematica which basically seemed to work.
However I liked the ease of use in Blender (especially letting me choose the seams and also making it easy to separate top an bottom “end caps”), including the visual feedback.
In my first link it seemed to me as if test-dr was able to also warp/bend the picture in the UV-Editor as needed. But I may be wrong.
