I am creating this issue separate #375 to keep each bug report focused and manageable.
To help us investigate and resolve this issue, could you please provide:

1. Specific details about the issue:

   • What render pipeline are you using? (Built-in RP / URP / HDRP)
   • What exactly happens when you enable both Outline and Transparency in UTS3?
   • Are there any error messages in the console?

2. Sample project with reproduction steps

   • A minimal reproduction project would be extremely helpful
   • Step-by-step instructions to reproduce the issue

3. Expected vs. Actual behavior:

   • Screenshots or videos comparing UTS2 (working) vs UTS3 (not working) would be valuable

Thank you for reporting this issue!
