I found that these two editors seem to have different functions.

Node Editor 1.1 jms = Is the Nodee ditor

nkallen Elephant = Is a step recorder ( https://github.com/nkallen/elephant )

the functions Video -> https://youtu.be/Axtxwt9-gww, https://youtu.be/jsTGCHa-pZk

nkallen Elephant = It seems that few people discuss,

Have more information for nkallen Elephant ?

Do I need to install both？

nkallen Elephant can auto creating Node & editin Node.

Node Editor 1.1 jms, can step recorder & auto creating .NOD in my working?

Hi Kondou, there are a few different versions linked to at:

I think the nkallen version is an experimental version which automatically builds nodes as you run regular MoI commands. It's a more intrusive install because you have to replace all of MoI's command scripts with customized versions. That can be problematic because of potential bugs introduced (I've had at least one bug report tied to that) and not having the current version. So it would probably be a good idea to do that on a separate MoI install from the main version.

No, if you want to generate your own node constructs you probably want just the James version at https://moi3d.com/wiki/nodeeditor
