// TODO: Currently we support viewDirTS caclulated in vertex shader and in fragments shader.
// As both solutions have their advantages and disadvantages (etc. shader target 2.0 has only 8 interpolators).
// We need to find out if we can stick to one solution, which we needs testing.
// So keeping this until I get manaul QA pass.
