    That just looks like vertex mapping, to be honest.
    Are my spline guides showing?

    hi,
    no, not just vertex mapping, the question is more of how one controls the node setup.

    You can control shadow amount with Shadows node
    (last DP Kit x32 update fixed an issue with area soft shadows),
    mixing a Color output (without shadows)
    with the regular shadows output blended with 'Multiply',
    the shadow amount is controled
    with something input in the Mixer Opacity,
    here a distance spot->sphere in a gradient,

    No gradient and gradient,

    A simple weight map(negative to positive)
    could be used as control.

    Denis, thank you so much for helping me out back in the days,

    i was wondering if you could help me a bit again...

    i have this other challenge where i try to replace only the self-shadow of an object,
    do you know if this is possible with regular nodes, without using buffers ?

    here's an image that explains a bit more >

    I don't understand exactly what you want to do, but could this help?
    I don't think it's self shadow, but rather the shading on the sphere. You can alter it's appearance with nodes like the example below. But that's probably not what you ment?!
