Aliasing/outline in render passes driving me insane...

[andrewrpreza]

Hello,

 

I've been rendering some stuff to the vray raw image file as openEXR and I can't get my render elements to look like my beauty pass.

 

The problem is that some parts of my image have this weird white outline, other than that the image looks identical but I don't know what is causing this. It's not there on my beauty pass.

 

You can see the problem in the attached screenshots, also my photoshop stack as you can see is nothing out of the ordinary, everything is setup correctly.

 

I'm using a LWF with clamp at 1 and sub pixel mapping.

 

Any ideas?

 

Thanks

Run a defringe by 1 pixel command on your layer that is giving you the issue. Often times, certain render elements are not AA in any way so you'll have a slight 1-2 pixel difference. Usually defringe, or mask refine command will remove that little white halo.

Thanks for your reply... I didn't render matte's though so I guess defringing wouldn't work since there are no transparent pixels. I ended up rendering non-raw elements and it added up correctly.

 

Is there any other way that's a little more straight forward? AA filter?

 

 

Thanks again!
