strange face color

Hello,


I guess a noob question, but i get these strange face colors in shading mode. When i lift the portal up (upper red arrow), even the background gets this greenish color (lower red arrow). Changing material color changes only the white. The green stays. What could this possible be?

    Weird, I've never seen anything like that before...but I have no idea what is causing it from just this screenshot.

    It looks more like some kind of shadow or ambient occlusion...Does it change when you move the piece around or is the green like it  is 'glued' on the object?

     And are your (especially GPU) drivers up to date?

    If you post a link to your .blend file (via Dropboxor GoogleDrive or so), I'll be happy to take a look.

    it changes when i remove a face and fill it again. it was greener before.

    I will check for the drivers, not done that in a while for sure. seems that it has something to do with me how i build that specific part i think.  Thanks for your quick response so far:)

    The link gives an  "Access denied". Google changed that some time ago and that is now default...I asked for access, but you might want to change the link...more eyes and so..

    Okay, your World is that dark green color.

    You have a very strong Sun (strength 500) pointing straight down, so everything is (over-)lit from above, but part of the "poort" is in shadow and because the World is green, so is the shadow. 

    If you make the World blue and give the Sun a strength of 7 for instance, you get this:

    Ok, that sounds logical. I increased the strength because i couldnt see its effect at low strengths. But this is causing it then? Cause in the picurte above i can see it obviously as well, i will have to pay with the lights?

    Yes indeed, play with the lights:)

    The thing is, that your Sun (a directional light!) points straight down, which gives really weird shadowing, not anything you are used to seeing in real life (especially not something you'd see with a real sun).

    You can also delete the Sun lights and add a Sky Texture to your World:

    The Nishita Sky has some pretty intuitive settings to play with.

    Thanks! I will have a look at that. I watched some node tutorials, getting some basic understanding allthough it s still a lot of hocus pocus :)
