Hey there,

got some strange, not really flickering, but kinda, when I rotate the camera.
Take a look here:

Any idea what might cause this?

(I have this quite often when rotating, no matter in which project.
Also, textures tend to skip to lighter/darker depending on the angle...)

Probably that's your environment map.
Make sure it's imported as environment map and not cube.
Try to make it darker, at least in some places (like the bottom)
Try lowering smoothness of material parameter where you're seeing the issue.

Hmm... always used maps in environment map mode since I started using these.

But look at this, here the same thing with environment and sky completely off:

Here, a different topdown shot of with env/sky on: (Watch the shadows)

here the same with everything off, smoothness 0, bump 0: (Watch the shadows)

Now, I have to say that this is (once again) on a mac. I can't check on Win right now as I don't have access to my win machine until Monday... maybe it's once again a mac thing? Would be odd though... Anyways, I'll report back then.

Maybe it's just specular from some light on the scene?
I can't say without having access to your project data.

Ok. I will check on Win10 first, after that I will prepare a test project.
