i’ve found this issue using the gradient component in a very simple definition but i cannnot find why y doesn’t fill with correct colors these areas.
Element 26 is the smallest area of this multiple curves, as seen on panel, and when i use the gradient it gets color 255,255,255 (white) but on the screen colors seem to work in another way
This is actually (reasonably) expected behavior. Note that Boundary Surface accepts a list of curves - in order to handle cases like shapes with holes in them, boundary surface processes all the curves it gets in a list at once - and there is no guarantee of a 1:1 mapping between the original curves and the output surface order. Just graft the input to Boundary surface and flatten (or shift paths / trim tree) out the other end to ensure the order is consistent.
