@i_mazlov Thanks a lot for your time.
You answered my question brilliantly.

Awesome, thanks @i_mazlov
Very nice approach to create an User Data entry.

How can I find this kind of information when it is not documented, as I suppose there are other UD options without a symbol defined?

Hi,
I'm creating User Data through Python and I'm able to create a dropdown list (combobox) with this:

cycle = c4d.GetCustomDataTypeDefault(c4d.DTYPE_LONG)
cycle[c4d.DESC_CUSTOMGUI] = c4d.CUSTOMGUI_CYCLE

But this is not what I want at all, but the old and classic radio button, as below.
I'd expect to find something like 'c4d.CUSTOMGUI_RADIOBUTTONS' in the documentation, but there is nothing even close to this.
Is it possible to be created in Python?

Thanks @ferdinand, you answered my question brilliantly, as you always do.
Cheers

Hey guys, how is it going with this BUG?
Is it gonna be fixed soon?
Thanks

Hi there,
In a ShaderGraph material I'm able to flip the spline in a Scalar Ramp node as well as invert the gradient in a Ramp node by using:

Flip()

InvertKnots()

Do we have similar methods for the Maxon API?
Do I need to invert the knots and points one by one manually?
If so I'd appreciate any examples.

Thanks a lot

Hey @m_adam ,

Thanks for your help. It works now.

However, I'm wondering how I would have known that I needed to set the scaffold ID to the node. The documentation doesn't seem to explicitly mention this step. I might be wrong, but for someone without strong knowledge of the API, I'd never thought that way. I would rather added the selected nodes to a group, as this is what a scaffol is. Does that make sense?

As a side note, after adding the nodes to the scaffold group, they appear messy, actually the nodes are nicely arranged inside the group, but the scaffold is overlapping other nodes. This is likely related to the bug we discussed here: https://developers.maxon.net/forum/post/73446. Am I right?

Cheers

Hi, I've been searching for examples on how to add nodes to a scaffold group in Python, but there is nothing available and the documentation is not helping too much as well....

This is what I was trying to do, creating a material based on the example from github and adding a scaffold and then trying to move some nodes into it. But of course it is not working as this is just an attempt from a trial and error.
Any help would be appreciated.

Thanks

Thanks @m_adam !

Thanks @Dunhou, I appreciate your reply confirms what seems to be a bug, and I wonder if @m_adam could confirm it based on the working code I provided, which demonstrates the issue in a simple way.
