Why are my carpet materials rendering like waves?

Hello,

I imported a material from maxwell's library called carpet01_disp, so that I could add my own pattern to the exiting displacement and tetxure settings to use it in my scene.

But even if I don't change anything about this mxm file, when I render the scene it always appears like large waves when applied to a flat floor object.

I already read this http://support.nextlimit.com/display/mx ... 1463089488 about displacement options and that doesn't seem to be helping me.

Please let me know if you can help!

Thank you,
Alison

Using real world scale?
Attach image or scene to investigate.

My model is is real world scale, but maybe there is something about the material that is cause it to not render in real world scale.

I can't seem to attached any images to this message...

Upload screenshots to an image hoster, get the "direct link" once uploaded and paste it in your post, select the link, then from the top row of buttons in the post window click on "Img" which will add img tags around your link.

Are you doing this in Studio? Can you see how the displacement texture is tiled on your object? Switch the viewport to Textured mode, and in the material editor, click the little yellow icon in the top left which lets you choose which texture in the material you want to see in the viewport.

It's a subdivision issue -- add more sub-d or sub-d the object before applying displacement.

Is there a performance difference if the sub-d is performed on the object or handled in mxed? For ease, it seems that using adaptive sub-d is the way to go.
