Thanks @moGRR for reaching out us.

With regard to your question, as pointed out by @zipit, it's not possible to have a Python Generator to generate object which can be recognized as real spline by generators/deformers expecting a spline as input due to the Python Generator flags used in its registration.

Beside the option mentioned by @zipit I also invite to have a look at this post where it's presented a generator outputting spline and accepting splines as input.

Best, R

Hi sorry to jump on this topic so late, and I agree that if you could do what you want in a Python Scripting tag its preferred, the mains issue with xpresso is that its a whole system that assumes certain things and was really not designed to be embedded within a generator.

So the issue about the AddNode, not working is because user data things, as an object xpresso node, is something dynamic (they will change according to the linked object) and I found no way except via the UI (by asking a UI Redraw or a whole scene execution) to refresh these data so the GvPort can be created.

But since you are in a Generator you don't have access to the GUI since all GUI operation should be done in the Main thread see Threading Information.

Cheers,
Maxime.

Ah brilliant. Thanks for that!

And apologies for being such a noob at this.

Thanks again @PluginStudent for helping me so quickly.

That was enough information to help me find the .MakeUserSpline function that allows me to do exactly what I'm after:

MakeUserSpline('sin(x * PI)', 5)

More info here for anyone looking.

Cheers,

Oops - I forgot to have the following line:

myDefObj[c4d.FIELDS] = myFieldList

It all works perfectly now. Thanks again for your help @PluginStudent
