Hello @pixelsinprogress, Thank you for reaching out to us. I must unfortunately tell you that it currently is technically not possible to set the alpha values of a c4d.Gradient instance in Python. In C++ this works because there Gradient::GetAlphaGradient returns a pointer to the underlying alpha gradient. The Python layer unfortunately makes a copy of that layer, severing the connection between the alpha gradient and its associated color gradient (which is also why the Python docs warn about that). I also tried some other venues of poking around in the alpha data by using C4DAtom.SetParameter, but these unfortunately also do not work in Python. I have created a ticket for this to be fixed at some point, as I would agree this is something the Python layer should be able to handle. But this is not a bug, as this was done somewhat intentionally. So, it might take a long time before we (most likely @m_adam) will find the time to do it. Cheers, Ferdinand

@m_adam said in R20 Startup script location - python_init.py: This will be fixed within a future release. Well, that's a relief then. Good to know. Thank you Maxime for the clarification. Kind regards, Tom
