Hi David, Geometry that changes colours/lighting randomly as the vieweing position or other state changes is almost always down to geometry in the scene not being completely defined, something like a missing colour or normal array on the fence geometry. If this arrays are missing then this state will be inherited from other geometry that do define it.
Your own shader is probably masking this lack of state because the shader itself is not relying upon this arrays. Robert.
