So I have multiple node groups in a material I want to change all this multiple node group to another node group in the shader. Is there a way to do this instead of selecting each node group and clicking the drop down menu and changing them to the desired node group one by one?
Afaik no.
Perhaps you can copy the material, change the group and then assign it to the desired selection.
you could write a small python script for that (but only if you have > 50 material, else writing the script takes longer than changing it manually…)
There should be an easier way to switch nodes like using link data between node groups or nodes. Like I should be able to select multiple nodes in a shader and select an active one and click on link data or something and all those nodes change and become instances of that particular active node.
I have no python knowledge unfortunately
It is not the materials. Its the nodes in the material. I want to be able to select multiple nodes and select an active one and all selected nodes switch to the active one, keeping their connections if they are valid.
Is this possible with a script? I am surprised we don’t have such a thing natively in blender.
