Mirror and Glass Reflections Problem

Hi Teams! I have some problem with the mirror reflections since I updated to the 3.0 versions (never have this problem with mirror reflections on D5 before the update). I have some several problems with them and here are my case:

  1. Here I used “brass mirror” material but the reflections seems not right on the wood cabinet, but the others is fine. So I tried to re-setting the mirror material by putting new brass mirror base and then it solved. (But it’s better if you guys can solve this bug)

  2. Tried to change the material into basic mirror didn’t solved the problem, as you can see the ocean only showing blue color, even tho I have setting them with waves and anything (there’s no specular, waves, etc only blue color instead). So, I also tried to use the same step as before (1) but it’s not solved.

  3. Here we think maybe because of the glass/window panel:
    We use the material in"brass mirror". Try to put the mirror behind the glass and its still the same, only blue ocean showed. And try to put mirror infront of the glass (because maybe the glass is the problem) but the ocean now looks fine but the other material like the wood deck beccome yellow.

Fyi, I opened all of the files and it becomes to look like this if there’s a water reflection on mirror with glass panel infront of it. So, does anyone facing the same problem? Would like some help from the teams also, thank you.
