Quote - If all you want is the displacement saved. Delete all other nodes in  your material. This will leave only the displacement node in place. Save the material to the Library. It's not that hard really. 

Let's say I do what you suggest. 

If I apply this material with ONLY the displacement node over a material with a diffuse & specular, will it remove the diffuse & specular or simply add the displacement in addition to the diffuse & specular?

Quote - You can create your own fikle via script and save the node information.  You can edit an mt5 file to remove the other nodes, BUT, as far as I know Poser will discard the rest of the material and load only whats in the file.

 

What do you want to do with only a displacement node ?

Sometimes I want displacement and other times I don't. I'm trying to create these quick files that will minimize the amount of time I spend in the material room.
