AttributeError: 'ShaderNodeTree' object has no attribute 'inputs' #77

When trying to import any models, I get the following error:

same here, have you found a solution?

twoexem commented 10 months ago

No, sadly not. Still waiting for @taniwha to check in on this.

I fixed the issue by downgrading blender to version 3.3

twoexem commented 10 months ago

Good to know! Have you tried importing the craft in 3.3 and then loading the .blend file in 4.0?

A quick search on the web tells us some breaking changes were brought to the node groups API in Blender 4.0. This is one of those. Replacing node_tree.inputs.new(type, name) by node_tree.interface.new_socket(name, in_out="INPUT") and node_tree.outputs.new(type, name) by node_tree.interface.new_socket(name, in_out="OUTPUT") should solve this error.

I still face other errors I haven't been able to tackle though, so the script is not working for me.
