Wondering if this exists, if not I’ll move it to the feature request part of the forum.
Is there a way to copy and paste parameters between materials, not just sub parameters, but like all the parameters except the maps?
I use the same setting on a looooot of materials, but they are all individual due to lightmaps.
Not at the moment AFAIK.
You could use the editor API to do this (copy a number of parameters to all other materials based on a filter (eg in the same folder, if they are prefixed with “something_”). I don’t think the API is documented though 
There was that PlayCanvas browser plugin that used some of the editor API and I believe it is open sourced so that could be used to get some help.
Thanks again, I’ll pass that onto our programmers.
