I created a simple Electron demo app that uses Babylonjs to show a simple animation of a textured 3D object. In the background it uses the the default environment and shadowGenerator.
On two of my PCs, the app works as intended with the 3D object coming in fully textured and the background looking fine (the default environment casting shadows, etc.).
However, on a third PC, the 3D object comes in fully textured as expected. However the background/ground plane is the red/black texture pattern that usually means a missing texture.
Any ideas why this may be? I thought it may be a graphics card issue but I find it strange that the 3D object comes in as expected but not the simple background.
