Tridi Viewer

Graphics or renderer problems

Troubleshoot Tridi Viewer startup or display problems related to Vulkan, OpenGL, and Windows graphics drivers.

Applies to Tridi Viewer 1.1.3 public beta. Release notes

Renderer startup

Tridi Viewer first attempts Vulkan, then automatically falls back to OpenGL if Vulkan cannot start. There is no user-facing backend switch.

What to try

  1. Install current Windows updates and the latest graphics driver from the GPU or PC manufacturer.
  2. Restart Windows, then open Tridi Viewer again.
  3. If the app opens but a model displays incorrectly, test a small known-good GLB to separate a renderer problem from a model import problem.
  4. If both a small model and the interface fail, contact support with the Windows version, GPU name, driver version, and a screenshot of the error.
