Reported in AnalyticalGraphicsInc/gltf-vscode#74, confirmed in Cesium 1.40.

The model Alien.glb causes Cesium to produce a vertex shader with these uniforms:

uniform mat4 u_modelViewMatrix;
uniform mat4 u_projectionMatrix;
uniform mat3 u_normalMatrix;
uniform mat4 u_jointMatrix[0];

The last line causes an error:

RuntimeError: Vertex shader failed to compile. Compile log: ERROR: 0:5: '' : array size must be greater than zero

Not sure if they are related, but there are a lot of validation errors:

The validation errors should be gone now, at least with the online version of the validator:

KhronosGroup/glTF-Validator#70

So the old validation messages went away, but a new warning has shown up for each of the nodes:

Node uses skinned mesh, but has no skin defined.

I added a fix for this (to ignore skinning when no skin defined) to #6421. I tested it with the Alien.glb and the face animations do work (and do look as super-creepy as they do in other engines). This should go into the May release of Cesium.
