Decal on a half sphere

Hello,
I have a round image that I want to apply to a half sphere. Spherical Decal offers 2 angles.
What do they correspond to? All my attempts have been unsuccessful.
I guess it must be so simple!
Thanks for help.
Michel.

Hi Michel -The angles let you specify how much of the sphere should be used for the image - the sphere is a polar one so the first angle sets the part to use in the around (equator) direction and the second one pole to pole.
However, I am not sure a spherical projection is the right one for this case - can you post an example with the image to use?

Thank you Pascal.
I’ve set both angles at start 0 and end at 180° without success.

Hi Michel - is this about what you are shooting for?

Here the decal is planar mapped from the Right view and the widget location adjusted.

Exactly!!

Thank you Pascal.
Can you explain the steps to obtain this perfect result ?

select your object, navigate to a ortho view so you are looking directly at the part from the projection angle. (imagine you are shining a flashlight on the part, that will paint on your image)

add a decal, and choose planar as the mapping type.

add your image and drag the decal onto your part-

adjust the widget for size and placement
