I have just starting using the Extreme PBR Add-on. Once you have made your adjustments/tweaks to a material apply it to said object, move on to another object and add a new material and so on. I can’t seem to figure out how to go back and make edits using the PBR material panel, it always just displays whatever the last material you made regardless of what object in the scene is active. Is this how it works or am I missing something? Is there a way to go back and edit materials you have already applied using the Extreme PBR window???
I use Extreme PBR (v3.3.46 which isn’t the latest) also, and I’m not seeing that behavior (currently using Blender 2.93.7). The “Material settings” will change for me depending on which object I’ve selected even if settings were changed. Are you using Blender 3.0?
Was using 2.93.7 but just switched to 3.0 and the behaviour is the same. Just to be clear, when I add a material with extreme PBR to one object then another. If I go back to the previous object, extreme pbr just displays the last material, not the material of the selected object. The only way I can make further edits to that material is thought the properties panel and the node editor.
