The Echo VR Replay Viewer is a standalone application that can read .echoreplay files in a recreated 3D arena environment. The Replay Viewer was created by Sneakyevil and Zzenith, with additional development by iblowatsports, NtsFranz, and BiffBish.

The project is open-source and is available here: https://github.com/sneakyevil/Demo-Viewer.

The viewer supports use on a flat monitor as well as in VR.

How to launch the Replay Viewer in 2D mode from the Oculus Store

GitHub Release[edit | edit source]

We will try to keep the latest GitHub release up-to-date for people that may not have access to the Oculus desktop app (Quest users). To install, extract the zip to a folder and run the .exe file. To run in VR mode, run the .exe with the -useVR command-line argument.

Usage[edit | edit source]

Loading Files[edit | edit source]

To load a file, click on the menu icon on the right side of the screen (shortcut: tilde). This menu contains a list of .echoreplay files in the folder that the Spark saves files to by default (C:\Users\[USERNAME]\Documents\Spark\replays\). At the top of this menu, there is an input field, where any file path can be entered if the replay is stored somewhere else on your computer.

To save your own replays, download Spark, or write your own program that saves with the .echoreplay file format!

File Association[edit | edit source]

File association is supported with the replay viewer, to make it easier for you to load downloaded files, you can associate .echoreplay files with ReplayViewer.exe by double clicking a .echoreplay file. When Windows brings up the "How do you want to echoreplay files from now on?" window, click "More apps", scroll down and select "Look for another app on this PC". Navigate to where you unzipped the application (GitHub Release), or to C:\Program Files\Oculus\Software\Software\franzco-echodata\Replay Viewer.exe (Oculus Store), and select "ReplayViewer.exe". Once you have done this, you can open .echoreplay files just by opening a file directly from File Explorer.

If you do not do this and you want to open files downloaded from the internet, you will have to copy the entire file location and file name of the file you want to view, and paste it into the field after launching the app. Files recorded with the Spark will save to a folder readable by the Replay Viewer and will not require this process to view.
