Hi,
I just made the update from 4.6 to 4.7.1, and I get some errors when loading my scene:
“v3d.js:1 v3d.MeshNodeMaterial: outdated Principled BSDF node cannot be used to obtain standard PBR props, please reexport your scene with Blender 4.0+”
I obviously also made the update to Blender 4.2, and re-exported my scene using this version of Blender, but it does not clear these errors…
Anyone has an idea how to solve this??
Thanks!

David

Depending on the previous version of blender you originally created your scene in the BSDF shader node may be incompatible. You will find the 4.2 BSDF is completely different. You will probably need to update your shader nodes on your scene by replacing the old BSDF nodes with the new version. I suggest looking at the other nodes and change logs to see if you need to update anything else.

Thanks! I think I got it.
I had some gltf imports in my main scene, and these gltf were not updated, which caused the errors.
This material issue is solved now!

To say it quick: it’s better to re-export everything (all gltf files) after the update, as I also realized that there was another issue with objects “morphattributes” that were not properly read on old gltf files. This is solved by re-exporting the gltf with the latest version.

EDIT: no it’s not solved… still have the morphattribute not defined issue… :(
