As a beginner to Blender I wanted to practice working with materials. I made a cube and created two materials for the cube, one for the sides, one for top and bottom. I repeated this twice (making cube, creating materials) and got annoyed with
adding new material
selecting nodes output
deleting DiffuseBDSF and substituting with Principle
adding two Image Textures and assigning to them a texture and a normal map
So I thought to speed up things a little and decided to copy an existing material, with the goal of just deleting the OLD images linked to the Image Texture and substituting the NEW images. And since all of my materials have the very similar name structure of material.png and material_n.png for texture and normal respectively, I had the even better idea to just type the new name over the old one in the Image Texture. Yes, I was too lazy to scroll through my 50+ materials. (In every other dialog window, I can quick-jump while pressing T if looking for a file starting with T. Not in Blender?)
So, that way I learned that you can retype the image name in Image Texture, but obviously you are just changing a kind of "internal name", because the referenced file will still be the same. True?
The correct way to "recycle" a material may be:
click on "new", choose any existing material
click on "number of users" to make an unlinked copy
by clicking on the "open" tab in Image Texture choose your new texture.
Am I right in this? If not, what IS the correct way when you are trying to keep your build-up nodes and just want to change the linked files?
(And why do I now have a cube which insists of showing me the normal map in Texture View, even with having the correct texture linked to "Base Color" in the Principled BDSF?)
Any help would be very much appreciated
