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 8 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 8 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.
