So I made some test renders using a hammered aluminum material on the groundplane. My boss loved the reflecty thing, and asked me to make an animation. It is quite simple; five or six things floating straight down one after the other to form an assembly. Here is the issue; the first frames start out with the groundplane almost white, yet as soon as each successive element enters the frames from above the scene gets a good shade darker. The exposure is locked. It is very distracting, and makes the animation unusable. I have changed the material several times, and it seems that any metal I use produces the same results. I finally had to go with a more matte material, which seems not to do it, but I really want the reflections in the groundplane, for the added wow factor. I also tried a glass texture, which seemed not to do it, but it looks a little odd, it’s not what I’m after.
