Gaussian blurring a cube map?

malcolm · Sep 2009

Anyone have any trick to gaussian blur a cupe map texture? I can generate a cube map but there will be seams in it if I blur it in photoshop. Ideally there would be some way to blur the map after its creation or generate a blurred map directly out of maya mental ray.

Hmm, hard. You'd need to lay out each face with the surrounding edges touching, then make a + shaped selection and blur from there.

Maybe extending out the corner /edge pixels.

How much blur ?

Blah, pictures worth a thousand words - this is how I'd do it :
