LuaMaterial warnings spam

Does this come from ZK or from Engine?

[f=-000001] Warning: LuaMaterial: incorrect uniform type for "ShadowMatrix", got: unknown expected: mat4
[f=-000001] Warning: LuaMaterial: incorrect uniform type for "SunDir", got: unknown expected: vec3
[f=-000001] Warning: LuaMaterial: incorrect uniform type for "ShadowParams", got: unknown expected: vec4
[f=-000001] Warning: LuaMaterial: incorrect uniform type for "ViewMatrix", got: unknown expected: mat4
[f=-000001] Warning: LuaMaterial: incorrect uniform type for "CameraPos", got: unknown expected: vec3
[f=-000001] Warning: LuaMaterial: incorrect uniform type for "TeamColor", got: unknown expected: vec4

It appears on start and every time /luarules are reloaded.

I tried to find where "SunDir" is mentioned in ZK and only found it in ghost_sites, although the warnings above look to have nothing to do with that widget & shader.

Why remove ModelMaterials_103/Shaders/default.lua? Looks good otherwise.

Q: Why remove ModelMaterials_103/Shaders/default.lua
A: It's same as ModelMaterials/Shaders/default.lua and not used anywhere (even by 103 stuff). Therefore it should not exist in order to not confuse people like me.
