Steps to enable the “Material Front” pin:
- Check Your Unreal Engine Version:
- Ensure you’re using Unreal Engine 5.2 or later, as the Substrate system was introduced in these versions.
- Enable Substrate in the Project:
- Go to Edit > Project Settings.
- On the left panel, select Rendering.
- Look for the Experimental section and check the box for Enable Substrate.
- Restart the Unreal Editor to apply the changes.
- Configure the Material to Use Substrate:
- Open the desired material in the Material Editor.
- In the Details panel, find the Shading Model option.
- Change the Shading Model to Substrate.
- Once this change is applied, the material output node should now display the Material Front pin, allowing you to connect textures and parameters as needed.
