Is it possible to have a group of nodes created by me, be installed in Blender?

I create a group nodes to corret HDRi exposure problems, and i use it frequently. Import it from origal file is boring and loose time. If is possible to install it in blender would great. I use Blender 2.79 and 4.1

Hi, i am not sure, but i think you can save it as an asset?

Moved to Support Materials and Textures .
@digitvisions is right: organize them in groups and then you can mark them as assets.
There is also a vanilla extension you can look at: https://extensions.blender.org/add-ons/node-presets/

I normally use ShaderNodeCustomGroups for nodes that I use often, specially if the node requires some UI that you can’t do with nodegroups…

Assets can also be a solution, but either ways it might probably helpfull to add the node (nodegroup/customgroup/asset) to the AddNode menu.

and even today I discover something new to study :scream:
