Chaos Visual Debugger (CVD) saves recordings as two types of files:
.utrace(Generated by saving a single-source recording.).cvdmulti(Generated by combining multiple.utracefiles.)
On this page, you’ll learn how to locate and load .utrace and .cvdmulti files into CVD for:
Load Single-Source Recordings
CVD stores .utrace files in different locations on disk depending on how they were recorded and what type of application was recorded:
| Application Type | Location on Disk | Example |
|---|---|---|
| Inside the project folder. For example:
|  |
Packaged build | Inside the project's build folder. For example:
|  |
Live recording | Inside the Unreal Trace Folder. For example:
|  |
Load a UTRACE File
To load a recording follow these steps:
In the main toolbar of CVD, click Open File.
In the Open CVD file dialog, Loading Mode is set to Single Source by default, so you don’t need to change this option. From the Folder dropdown menu, select the folder your recording is stored in. Click Open Folder.
Select the
.utracefile you want to load and click Open.
Load Multi-Source Recordings
Load Multiple UTRACE Files
Loading multiple single-source recordings is the first step to creating a CVDMULTI file. However, this can also be useful for visualizing two single-source recordings simultaneously to inspect for discrepancies.
To load multiple .utrace files, follow these steps:
In the main toolbar of CVD, click Open File.
In the Open CVD file dialog, in the Loading Mode dropdown, select Multi-Source.
From the Folder dropdown menu, select the folder that contains your recording. Click Open Folder.
Select the
.utracefiles you want to load and click Open. CVD automatically loads both files.
Create a CVDMULTI File
Once two .utrace files are loaded into CVD, the Combine button becomes available in the main toolbar. Click Combine and save the new .cvdmulti file at your preferred destination.
Load a CVDMULTI File
To load a .cdmulti file, follow these steps:
In the main toolbar of CVD, click Open File.
In the Open CVD file dialog, verify that the Loading Mode is set to Single Source. From the Folder dropdown menu, select the folder that contains your recording. Click Open Folder.
Select the
.cvdmultifile you want to load and click Open.
There is a known issue where the first frame will not automatically play after the file loads. Geometry will not generate until you click the Play icon in the Game Frames Timeline.
