@ferdinand said in Can a plugin use the native Node Editor for its own graph?: Hey, sorry for the delay. I checked and it is not possible to have arbitrary node systems, i.e., node systems that are neither scene nor material nodes. In the backed of things, you actually have almost all you need, so you could implement a node system that outputs sound files for example. One of the major hurdles is that this menu is hard-coded at the moment: [image: 1793790825815-b6453bab-c4e5-4ea3-9273-eb76465a7257-image.png] So, there is no way to display your node system of a custom node space purpose type. Cheers, Ferdinand I did manage to add a space to the dropdowns but couldnt connect the viewer to that. although it was only accessible from the top shelf menu Render/node space.
