How to change alpha value of all material in a single go? I have a blend file in which all the materials alpha value is 0.
There are too many materials for me to change the alpha value manually to 1.
Is there a way I can change alpha valuec of all materials in a single go??
Try running this script
import bpy
for mat in bpy.data.materials:
    if not mat.use_nodes: continue
    for n in mat.node_tree.nodes:
        if n.type == 'BSDF_PRINCIPLED':
            n.inputs[&quot;Alpha&quot;].default_value = 1
