Gtuner Setup (Titan Two)

Follow this guide to configure Gtuner IV for Cosmic Vision, load your GPC script, and connect your capture card.

Requirements

Before starting, make sure you have downloaded and installed all required programs and environments in the Installation Guide

1. Open Gtuner

Launch Gtuner.

Note

When launching Gtuner, ensure Helios or other Titan Two applications are closed for proper functionality.

2. Set Your Python Environment

  1. Go to Tools → Preferences → Computer Vision
  2. Click Browse

  3. At the top of the pop-up window, paste in your environment path from the Cosmic Environment Installer: C:\Users\{USERNAME}\Miniconda3\envs\cosmic_env

  4. Press OK

Tip

This must point to the exact environment created by the Cosmic Environment Installer you ran earlier.
The installer has a helpful "Copy Path" button for convenience pasting.
If Gtuner cannot find Python, re-run the environment installer and click Reset.

3. Set Your Script Directory

  1. On the left side, locate the File Explorer panel

    • If you do not see it: View → Reset Layout

  2. Locate your Cosmic Vision folder and click on it to highlight it in blue.

  3. Click the folder icon beside the refresh button
    This locks the folder so Gtuner always opens it by default.
