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

control+L

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
