Any ideas how this is done?
Hey guys, I just came across this video on Vimeo, and aside from the tidy animation, I was wondering how the background is done at about 0.41. The ball is clearly 3D, but the background is 2D. I'm guessing some kind of compositing went on but I'm not sure what: http://vimeo.com/10823553 -
Re: Any ideas how this is done?
if you use vray you can animate the ball and put a plane where the blueprint would be, give it a white material, rightclick it and under vray options you need to set the alpha distribution to -1 and affect color and shadows ticked. -
Re: Any ideas how this is done?
Ok I've got problems again :) All my render passes are black with no alpha info. They have an alpha channel, but it's empty. So I'm not sure how to overlay them. For example, the spec pass is just a flat image with a black background, as are all the other layers, so I can't composite them. The masterBeauty renders out with… -
Re: Any ideas how this is done?
Ok just an update on this because it was bothering me. Apparently the useBackground shader is broken when using render passes. It won't render shadow passes, which is why I was getting a black result. The workaround is a bit unnecessarily complex but it works, you need to create a custom contribution pass, with a… -
Re: Any ideas how this is done?
this is the shadow for the bg right? this is how i would render it Create a new render layer. Add the bg and the ball. switch the primary visibility of the sphere to off. put use bg on the plane. render that. providing it works like mip matte shadow you will have a black render with the shadow in the alpha. render that. -
Re: Any ideas how this is done?
Ok thanks guys. Ok it's pretty much all working except for the shadow. I'm just getting a black output with no alpha, or an empty alpha on the shadow pass. In the scene, I've just got a plane background with a useBackground applied to it. -
Re: Any ideas how this is done?
All those bar Shadow/Diffuse are additive. for the others you can propably just pull the alpha from the beauty pass and use that. out of interest why are you splitting it up so much? beauty, shadow and bg would be plenty -
Re: Any ideas how this is done?
I'm using DiffuseColor, Spec, AmbientColor, Incandescence, and Shadow. -
Re: Any ideas how this is done?
The black shouldnt be a problem for the spec. Spec is additive so you use screen or addition to apply it. any black areas are just ignored. what other layers are you using? -
Re: Any ideas how this is done?
thats comp, you might give a try to nuke, really robust for this kind of work. just like they said render your passes and combine them in a comp software. The lines and stuff thats up to you. I ll suggest you do something of your own really. I ll probably do all that in illustrator, bring it to photoshop for subtle…
