Edge only & alpha render?

Ok I’m working with toon edges and I’m rendering them sepparately cause the original edges just don’t give me the result I require.

So the only way I can think of is by setting all the materials to not render by clicking all the “env” buttons… but since of course there’s lots of materials I’m wondering if there’s a quicker way???

And ehm… how did you render an animation with an alpha channel again cause I’d love to render edge only on a transparant background… preferably not as a huge series of images but as 1 animated file… doable???

create your invisible material and apply it to one object

select everything else


choose materials

Well yeah that’s nice, but since I’m doing lots of sepparate scenes I’d have to still reasign all the materials after for the next scene.

that’d be cool
