Terrain not working with latest update

[klepto2]

Since the Collision/Hole Update terrain throws a validation error:

Validation Error: [ UNASSIGNED-CoreValidation-Shader-InputNotProduced ] Object 0: handle = 0x8168780000000092, type = VK_OBJECT_TYPE_SHADER_MODULE; | MessageID = 0x23e43bb7 | fragment shader consumes input location 0.0 which is not written by vertex shader

Shaders now updated.
