Can you check all materials that using a specific node?

@J_Kalva

sorry for not being clear, but I am looking to find a way to check which Materials are using certain Material nodes (Texture Sample, Static Switch Parameter, Quality Switch nodes for example).

The blueprint tool was an analogy to the perfect solution, where you search for a BP node and it shows all the BPs that are using that node (found under Tools > Find in Blueprints), except that it works for materials instead of Blueprints.

I believe the python API doesn’t have anything exposed to get such information from materials, though

Hello, J_Kalva

I understand your need to find which materials are using specific Material nodes in Unreal Engine, similar to the “Find in Blueprints” tool. Unfortunately, Unreal Engine doesn’t have a built-in tool for this exact purpose. However, here are some approaches you can consider:

Manual Search:
You can manually search for materials by opening each material and checking for the specific nodes. This is time-consuming but straightforward.
Python Scripting:
While the Python API doesn’t directly support this, you can write a custom script to help. Here’s an example to get you started import unreal

def find_material_node_usage(node_name):
asset_registry = unreal.AssetRegistryHelpers.get_asset_registry()
all_assets = asset_registry.get_all_assets()

for asset in all_assets:
    if asset.asset_class == 'Material' or asset.asset_class == 'MaterialInstance':
        material = unreal.EditorAssetLibrary.load_asset(asset.object_path)
        if material:
            nodes = material.get_editor_property('expressions')
            for node in nodes:
                if node.get_name() == node_name:
                    print(f"Node {node_name} found in {material.get_name()}")

find_material_node_usage(‘TextureSample’)
Community Plugins:
Check the Unreal Engine Marketplace or community forums for plugins that might offer this functionality. Other developers might have created tools that can help with specific needs like this.
