Hey guys,

Im not a Cinema user (though i use BP quite a bit) i'm investigating the possibility of rendering a few scenes created in Max through Cinema using the Sketch and Toon shader. Now my question is this, the model/scene itself (for print) is already fully textured, its some kind of concept design for a hip down town cafe, im wondering how the sketch and toon works, is it material based or can it be applied to the over all renderer? .. that probably doesn't make sense, the thing is, because the whole thing is already textured i dont want to go in and start messing with the textures, recreating shaders etc .. be cool if i could literally fire the scene into Cinema then open the ST interface, play around with the styles etc and hit render?? .. can it work this way? or do i have to go in and recreate all the shaders? again im not a Cinema user so im digging a little blind here, hope that all makes sense :)

Best,
Dave.

You dont need the shaders to render--S&T applies its own shaders and works off the geometry--although it CAN work off the shaders/materials as well. Very flexible.

Sketch and toon is a line based renderer not shader based, so as Joel said you can easily apply it to a scene while still having your shaders/texture maps intact.

By default sketch does override using a quantized shading mode, but thats a single setting you turn off.

S&T's real strength is in outlining objects. It can easily add a realistic-looking natural media stroke to any object. It's actual shading leaves something to be desired though.

You can create separate art shaders that are somewhat limited in their functionality but that's not what you want for a pre-textured scene anyway.

As mentioned above, in combination with rendering outlines you can essentially posterize the shader output to simulate a paint-like or graphic texture. But unfortunately there's no global setting that can be applied to an object's shading as it can with the outline. The best way to do this is render it once normally then render the outline in S&T. Composite the two renderings in Photoshop and add some sort of effects to the normal rendering to simulate watercolor, brush strokes, etc.

You have a number of options for how to modify the shading from the post effect under it's "Shading" tab, so it's not quite true that you can't apply an effect to everything, indeed by default it will have a quantize posterisation effect applied, however the OP indicates that they want to turn that off, which they do by changing the value in "Object" under that tab to "Off".

To the OP - You can actually try out Sketch & Toon for yoruself to find out how it works, the only downside is that to do so even though you have C4D/BP you will need to download the full C4D demo (it has all the modules) to do so.

Thanks guys,

Yeh i'm pretty much up to speed with it now, i managed to have a play this morning, it seems l can literally just select every object and apply the sketch/outline shader to that and turn off the internal quantization. Though to correct above i do need the textures to have a slightly water colour effect, so thats probably my next challenge. I'll download the demo when i get home and have a play.

One thing i did noticed, i'm unable to recall the actual option but there was a tick box in the line selection, i think it was the option to render internal lines or something around there, when i selected this the whole render took around 30 minutes! (at which point i cancelled it) compared to the few minutes it previously took when unticked.

Thanks again,
Dave.
