Hello,
I am using Extrem pbr for material shading and i ran into this thing where it for some reason gets lost of its material data. If you dive into the nodes it points to the correct location. But looking at the scene all materials turn black.
Anybody experienced this as well and what causes this, or better how to solve?
Thanks in advance!
Hi Martjjn, i’m having the same problem and I think it’s because of update.
Did you solve it?
Check the link and if it’s not the information you’re looking for
Ask the Addon developer
In this case there may be a problem when creating a file in a newer version of Blender, and then after saving the project it is opened in a previous version of Blender.
Sometimes Blender updates its nodes, so it may be that the nodes are no longer retro compatible with the previous version. To solve this I have provided a function that tries to replace the “Unknown” nodes
You can find it in the Extreme PBR Options menu in this paragraph: Adjust All Material Node Tree

No, work around was to copy stuff to a new blender file (objects in one blender window to another) if i am not mistaken was that what i did…
