background Non-photo realistic renderer

OK, having a dumb moment
How do you get the background image to render "as is" using the non-photo-realistic renderer?
or can't you?
do you need to add alpha and add it in post?

    unfortunately adding alpha it all ends up transparent, not just the background
    normal renders do not do this
    adding transparency to the BG in the NPR I get this layered in Gimp

    using alpha in the photorealistic renderer worked as expected on the layer in Gimp

    I am at the moment after many different attempts in the NPR settings and alpha settings rendering TWO image series for my animation
    a NPR one and a photorealistic one with alpha, alpha only to marry together on a plane in the diffuse and alpha texture channels in front of my BG!!!

    Sorry for my lack of ability to help, here, at the moment.
    Just one thing:
    Have you applied the Toon settings via the Scene Modifiers? I believe that there might be Background choices in there.
    I never knew of this until I opened the manual while sitting on the pot.
    It allows for many more options throughout the scene - rather than simply applying the Toon to the render engines result.
    Instead of taking my distant memory as advice... try checking the manual and look for that option under:
    Scene (big bold word in the instances tray) > Modifiers or Effects Tab? Can't remember. But you add it with a plus sign, like you would a modifier.

    You probably already know that you can group things together, and set that group to be a single element, Toon-wise - so that it outlines that whole group as a single object - rather than everything within the group individually.

    The manual has some great stuff about this - but then you get into the actual Toon settings - and it gets even deep - as You probably already know much more that I... I am just hoping that one little thing that I say might create a spark that might help! :)

    Go Girl... make this work!

    Oh... and Wendy...
    You Freaking R O C K ! ! !

    So... were you able to get an alpha that included the brush strokes? Or does it trim the alpha based on the model's geometry?

    Could just put a big white block (cube) back there

    My bad. I suppose that doesn't work as a scene level plug, does it? Maybe a feature request? But that's not going to help you now.
    Okay... I'll read through more carefully and put my thinking cap on. Dog gone pain meds make focusing hard! lol

    no I cannot get the NPR to add an alpha background, it is either all transparent or semi transparent
    I am doing the alpha channel separately now using the normal renderer
    Ideally I would just like the backdrop image series to render

    OMG I am going nutzoid with this
    rendering a separate alpha channel he is STILL semi transparent!!!!
    I am now doing a full photorealistic render as the BG so at least the see though bits show the same colours underneath
    diffuse
    alpha (yes I only used ambient light a white shader but still shadowing!)
    BG

    solved the opacity issue for alpha channel of part2
    GLOW

    put white glow in white shader

    ps, how do you just render an alpha channel in Carrara?
    I CAN do it in iClone, all scene elements are a white mask, but never figured it out in Carrara
    I am sure multi pass can do it but I just cannot find it

    Delete all your lights (or group and hide them). You will render out a black alpha mask without any detail, but it should render very fast because there are no lighting calcs or raytracing.

    lol, I took the wrong approach, tried to make figure all white (no lights full ambient)
    will try that next!

    Probably the same difference... Actually might be interesting to know if one is faster than the other...

    very interesting Wendy, sorry can't add anything you haven't tried.

    my video http://www.youtube.com/watch?v=ybTuetguMds

    a backdrop on a plane renders albeit patchy strokes but getting a backdrop to work honestly more trouble than it is worth.
    is a pity as the NPR would be great for titleling
    cinegobs keyer and a chromakey blue or greenscreen paper colour is prob my other alternative.

    That is totally awesome! "I should put you over my knee and spank you!"

    Hey, a buddy of mine just sent me a link to the release note on the new freestyle render engine for the newly released Blender 2.67

    Here is a really cool animation found further down that page. Looks very promising! There are a lot more demonstrations of its possibilities from blueprints to...
