About Texts being affected by the Shader:Dialogue-Options, Speech-Text and Narrator-Text should not be affected by a Shader, but Object-Texts will be. At Least from my Experience. So, did you use Object-Text for displaying the Speech-Text at the Bottom? If you use Narrator-Text, it should remain still, just like the Dialogue-Options.About Hotspots, yes, they are not seen as Interface, so sadly they are affected by Shaders. But in your Case, you are lucky! The Hotspot moves with the Object it should highlight -- sounds like it should be that Way. (In my Game, the Hotspots turn blue at Night, together with the whole Scene -- that is far worse. ;) )However, the Polygon for an Object surely doesn't move with the Shader, so I guess that might be slightly irritating in some Areas.
