Auto Material Instance Generator [UE5]

Problem:
Manually creating Material Instances (MIs) and plugging in texture sets is slow, repetitive, and takes valuable time away from artists.

Solution:
The AutoMI Generator is an Editor Utility Widget that automates MI creation out of a batch of texture sets, using any master material and given naming conventions, generating a batch of ready-to-use MIs in seconds based on customizable suffix mapping.
`
How it works:
1. Select any Material with exposed parameters to use as a Master Material.
2. Define your source texture folder and your desired output folder.
3. Enter the corresponding suffix next to the associated parameter in the dynamically generated table (e.g., _N for Normal Map).
4. (Optional) Adjust output naming conventions to match project standards.
5. Click Generate Material Instances to batch-create your assets.
