i ve already tried obj fbx and abc with Cd attribute as point or vertex , but hasnt worked yet. Is there some other way to export my curves with their respective color information to Cinema 4d?

Alembics with vertex Cd attribute is the normal way. I don't know about C4d though. Maybe you can't.

Having the same problem.

There is a path, but it needs a couple of 3rd party tools.

For Houdini, I use this SVG importer/exporter:
https://github.com/Aeoll/ae_SVG [github.com]

This one is a bit of a pain to install, but if you work heavily with curves from Illustrator, or need to get curves into other apps, it's a godsend.

For Cinema 4D, grab this free SVG importer plugin, that brings in the curves with colours:

If you don't need the colours, you can use Illustrator to convert the SVG to a .ai that Cinema 4D recognises natively.
