A very very easy render for Sketchup ;)
As SKetchup is free and Moi exports as SKP format that can maybe interest you ;)

My little try :)

Merci Pilou:also render in NPR(cartoon-sketch) ?

...i have another question for you regarding Sketch up free
i used it some time ago and if i remember correctly i can't export SKP camera in C4D:is it correct?
does exist any plug-in or a trick to do this?

I have not tested an NPR rendering, but as Sketchup has a ton of "Sketch style" I don't see why not this will be not faisable :)
I will say more tomorrow!

About the camera, seem the new free sketchup V8 can export in Collada DAE format so seems no problem for exchange file ?
Else with Pro version I believe there no problem for import camera

Hi m-dynamics,

i did a bit camera matching long time ago in SketchUp and other apps.

AFAIK the free vers. of SketchUp does not export camera coordinates in an .skp or Collada file,
while the Pro vers. exports cameras as polygon meshes.

What i did was the following:

I installed this script:

to get the camera coordinates in SketchUp for use in my other app,
and used this script:

to match the SketchUp viewport size with the Window/Rendering size of my other 3D app.

Hope this helps a bit!

Stefan

About the NPR rendering, seems there is not but you can make a render and add a screen of any style sketchup drawing ;)

SKP have an excellent tracking system to match image background and rebuild directely facades on it
in C4D i use VREEL 3D PHOTOMATCH plug-in,but just to match background images with models
-------
i think in next future all renderers will turn or implement a real time option...

many thanks Stefan and Pilou !
