Hey @r_gigante ,
Got back to this issue, I'm trying what I think is the fastest and easier path first, to create a new pure spline in the end of my modifier chain. But still no luck...
I am sure the new spline is not being marked as dependence and is not being touched. Even though there's no deformers inside it, it has a deform cache. If I put the spline outside of my object, it will render, but I can still see it's got a deform cache. So maybe that's not the problem.
The same does not happen for polygons, any polygon that I include inside the object or modifiers are rendered (of course, they are not touched), unlike the splines.
Looks like the determinant factor to render the spline is the presence of
OBJECT_INPUT on my generator (modifiers and end spline are inside it). Just removing this from the object register makes my spline render.
What exactly is it doing to the children?
Can I still create and use dependence lists if I remove it?
