3. Select “Windows” and “Build” the project
4. Download, install, and open “RenderDoc”
5. Select the “Launch Application” tab
6. In the “Executable Path” field, enter the built project’s executable path
7. In the “Command-line Arguments” field, enter “--force-vulkan“
8. Press the “Launch“ button
9. Once the project is running, click the “Capture Frame(s) Immediately“
10. Double-click the capture in the “Captures collected:“
11. Navigate to the “Event Browser”
12. In the “Filter“ field, enter “MeshSkinning.SkinOnGPU“ and press Enter
