how do I get rid of black halos from maya exports?!

Yonderboy

Hi there,

Im making some 3D assets than Im rendering out of maya using mental ray, Im then importing them into photoshop to use. Problem is, it keeps giving me a 1-2 pixel black halo around the edges where the alpha starts :-/

Would anybody know how I could get rid of this?

many thanks

just exported it at twice the size and it seems to have done the trick

Rendering against a transparent background and choosing to also create an alpha for the render is a more correct solution.

.Wiki

I guess you are using the PNG-Format to save your renders. I would recommend you to use EXR since it doesnt premultiply the alpha.

in the top Menue
Layer --> Matting --> Remove Black Matte

.Wiki - Whats an EXR file? I don't seem to have that in my dropdown :-/
oglu - I don't seen to be able to find any layer menu - where could I find it?
throttle kitty - Im not quite sure what you mean - would you be able to elaborate?

thanks for all your help guys!!

in photoshop in the top menue..

oh i see (I thought you meant in maya ) Defringe seems to do the trick. Would still like to be able to stop it being exported in the first place though.

thanks Oglu

as Wiki mentioned use the EXR file format...
its the standard file format for rendering...

I've just tried that and I still seem to get a slight haloing. Im wondering if Im just rendering the images too small (1024x768)

have you tried using a real compositing software like nuke or fusion?

Yonderboy

no - just photoshop. No worries - increasing the render size will do the trick - thanks
