Globe Materials not compatible with enableLighting = false

See original GitHub issue

Closely related to https://github.com/AnalyticalGraphicsInc/cesium/issues/6039, but use-case is different nevertheless so decided to open a separate issue (cc @lilleyse as he might be working on this already).

Steps to reproduce:

https://cesiumjs.org/Cesium/Apps/Sandcastle/index.html?src=Globe Materials.html&label=Showcases
set viewer.scene.globe.enableLighting = true; on line 7

Result: shader compilation fails

Desired result: not have any time-of-day lighting effects, but still be able to use a globe material for slopes / heights.

That looks great! We have a pretty nice “splatting” layer in osgEarth that we could probably port to Cesium using globe materials. Basically you feed in a land use raster to the GPU and figure out what texture to repeat based on the land use code (grass, rock, same, etc), the normal and elevation.

Here’s a screenshot of what it looks like in osgEarth

I’m not using globe materials directly, but experimenting with code based on it to generate snow 😃:
