Hello,
I would like to use UV Relaxing and in particular pass the current edge selection via RELAXUV_EDGESEL_POINTER to create UV seams on the selected edges.
Basically the script does the UV Relaxing and I can see this clearly in the UV Editor Window, it doesn't report any errors and the res of SendModelingCommand() also returns True. Also I check via print(edge_selection.GetCount()) if my selection is passed at all and the count always matches the current edge selection. However, the relaxing does not use the edge selection as it would work in UV Manager via the UV Relaxing tab.
I also found an older thread from 2016 mentioning that RELAXUV_EDGESEL_POINTER expects a string reference to a selection tag, although the SDK clearly indicates that a c4d.BaseSelect is expected, of course I tried that too, but that also remains unsuccessful.
