Rendering fails - 'Vertex shader failed to compile'

JeanneKahn opened this issue · 2 comments

Installed the workshop to see if I can use it for teaching Cesium, but found this error when starting up from both npm and python:

An error occurred while rendering. Rendering has stopped.
RuntimeError: Vertex shader failed to compile.  Compile log: ERROR: 0:50: 'w' : vector field selection out of range

Console errors also included.

I am on Kubuntu 22.04. I tried installing WebGL drivers to fix this, but it didn't (and Cesium works in general for me as well, so it's not something across every Cesium application)

I've figured out that if you rename the CesiumDrone.gltf file, this error doesn't happen. I suspect something is wrong with the model provided.

@JoshuaKahn I got the same error message. How did you fix it?
