I imported an FBX containing hundreds of models, each one having 6 shaders. They all get metallic at 50%, I need them at 0. Is it possible to write a script to change them all together, otherwise it will be impossible to manage.
import bpy
context = bpy.context
for ob in context.scene.objects:
if ob.type in ('MESH', 'CURVE'):
for slot in ob.material_slots:
if slot.material.use_nodes:
node_tree = slot.material.node_tree
mat_output = node_tree.get_output_node('ALL')
node = mat_output.inputs[0].links[0].from_node
if node.name == "Principled BSDF":
node.inputs[4].default_value = 0
slot.material.metallic = 0
