I have made a woodgrain procedural texture and keep it in a blend file so it can be appended to materials in other projects. I am able to append the texture to a project and Add the node group to a material in a project. It has x,y,z inputs in order to align the grain with the object's geometry. All that works for a single use of the node group. I would like to use it for more than one object in the same scene but with different settings but unable to get it to work independently. I have unlinked materials for the objects but any adjustment to my texture carries over to all objects using the texture group. I could store several versions of the texture and append them all but that doesn't feel right. Is this a limitation I have to accept or have I got it wrong?
Edit. I have found that independent instances of the appended node group can be achieved by ungrouping each instance, dispensing with the input block and using the sliders inside the nodes instead.
