ℹ️ About This Script

This batch file is only a helper tool to quickly create, update, or reset the REDSHIFT_PATHOVERRIDE_FILE environment variable.
It does not change Redshift’s core behavior — it simply automates setting the override file path for convenience.

The concept of REDSHIFT_PATHOVERRIDE_FILE is explained in Maxon’s official documentation:
👉 Redshift Environment Variables – Maxon Help

This script was inspired by that documentation to make everyday workflow faster and easier.

📖 User Guide for Redshift Path Override Setup.bat

🎯 Purpose

This batch file is created to manage the environment variable REDSHIFT_PATHOVERRIDE_FILE on Windows, helping Redshift read the redshift_path_override.txt file in order to change Proxy paths.

You can:

1. Update the environment variable to point to the current override file
2. Create a new override file (mapping Old Path → New Path)
3. Reset and completely remove this environment variable from the system

---

🖥 How to Run

• Double-click the .bat file or run it via Command Prompt
• When opened, the CMD screen will show these functions:

[1] Update environment variable to point to the current override file
[2] Create a new override file
[3] Reset (completely remove REDSHIFT_PATHOVERRIDE_FILE from Windows)

👉 Enter 1, 2, or 3 then press Enter.

🔧 Detailed Functions

1️⃣ Update environment variable

• Select [1]
• The script will check if there is a redshift_path_override.txt file in the current folder.
• If yes → it will assign:

REDSHIFT_PATHOVERRIDE_FILE = path\to\redshift_path_override.txt

• Variable will be set for both current session and Windows Registry
• If not found → it will return an error.

➡ Use this when you already have an override file and just want Redshift to read it again.

---

2️⃣ Create a new override file

• Select [2]
• The script will delete the old override file (if any).
• Then, you enter step by step:

Enter Old Proxy Path (type "Done" to finish):

• Input the old Proxy path → Enter
• Input the new Proxy path → Enter

Example:

Old: D:\Assets\Proxy\House\
New: E:\Server\Proxy\House\

• Each OLD_PATH → NEW_PATH pair will be saved into redshift_path_override.txt
• When finished, type Done
• The script sets the environment variable REDSHIFT_PATHOVERRIDE_FILE pointing to this file

⚠️ Do not delete this .txt file — Redshift reads directly from it.

---

3️⃣ Reset (remove environment variable)

• Select [3]

• The script deletes REDSHIFT_PATHOVERRIDE_FILE from:

  • Current CMD session
  • Windows Registry

• If still visible in the Environment Variables list → log out or restart CMD to refresh.

➡ Use this when you want to remove the override completely.

🔍 How to Find Old Proxy Paths

If you don’t know the Old Path of a Proxy/Texture:

1. Right-click your .rs file → Open with Notepad
2. Look for texture paths inside, for example:

/D/Assets/Proxy/Building/wall_diffuse.tx
/E/Server/Textures/House/floor_normal.tx

3. Copy these as the Old Path and set your desired New Path in the override file.

✅ This is especially useful in multi-machine studios, where different artists may have different local paths.

---

✅ Usage Tips

• After changing the override file → restart Houdini, Maya, C4D, etc. so Redshift loads the new path.
• Recommended: place the .bat file in the same folder as redshift_path_override.txt.
• For multi-machine studios → copy the .bat and .txt file across machines for syncing.
