Weird circle in brushed metal texture...

[johnnyswedish]

Hi Corona Forum!

Happy New Year to you all 👍 I have created a simple brushed aluminium texture and getting a weird circle in the middle of the box shape that I applied the texture to. It is a cigarette pack and the texture is applied cubic at 5%. Anyone know why this is happening?

Many Thanks!

I think this is the same as https://forum.corona-renderer.com/index.php?topic=11044.0
So while it may be unexpected, it seems to be the result of the way anisotropy works in various renderers.

As a max user, i have hard time reading C4D shaders, but it seems to me, that your anisotropy is too extreme. If i understand it correctly, it goes from full anisotropy to none in very compact space. Try to lower anisotropy value or change noise colours from full black and white to slightly different shades of grey and see if that will help.

Give a try to set noise texture space to 2D.

As mentioned, Try lowering the scale. 10,000 seems a bit extreme. ;)

Hi All,

Thank you all for your responses. I will try this out when I get a chance. I have had to do this project with C4D standard renderer as I am having problems with displacement maps. Bummer! Struggling to get the same results as Corona :0 John
