OK , I searched around a little bit , and on Timo's site there is a Shadow Pass
shader which removes shadows
from the render and sends them to a separate channel where a user can modify
them in post .
I'll look at this and see if it is the solution to removing shadows from
certain objects .

Hi Arjo & Henri :
You both have SynthEyes ! Great . Good looking work Henri .
Now , I have an advanced question about shadows and CGI
objects . The thread is also on the forum but no replies .
http://www.3ddart.org/index.php?name=PNphpBB2&file=viewtopic&t=934
OK , this is difficult to explain ... I have a rectangle that is
a 'stand-in' for the ground plane in the video . It is catching
shadows from chrome spheres I have added to the video . Good .
Now , I want those chrome spheres to catch shadows from an
invisible object because there are prominent shadows in the
video on the ground area . Good so far .
The problem is that I do not want the ground-plane rectangle
to catch shadows from the invisible object , but to only catch
shadows from the spheres . The video is providing the shadows
already to the ground plane rectangle , no more are required
(except from the CGI chrome spheres of course) .
Here is the video showing what I do not want to happen .
(notice an ugly shadow on the ground plane across the center)

How can I place shadows on some objects , but not on other
objects ? Do I have to export certain shadows to a Post Proc-
essing program like Adobe After Effects ? How would I do that ?
Could I do it in the RS3D Post Processing using a channel
that will place those shadows ? How would I set that up ?
I'm even having a very difficult time doing it in RS3D in 2
passes , because I am using chrome spheres and any object
omissions in the second pass will show up in the reflections .
As I mentioned in the Forum , in the old days of V3.x we
would simply place certain types of lights in various levels
with certain objects . We can't do that in later versions of
RS3D because of the Gi calculations (according to Vesa in
the forum) . Fine , but is there a workaround for that ?
So what can we do ? There always seems to be a workaround
in RS3D , but does anyone have a method ?
Thanks in advance .

Hi Arjo,
Animation was done mainly with Light Wave since our 3D department uses that
mostly. Compositing and color
correcting, keying etc with Digital Fusion and 3D trackin with Syntheyes.
BTW multipass Lightwave renders were combined, graded and composited in Digital
Fusion for better control
and workflof benefits. No direct renders were used "as is"... which is mostly
the best way to work with
Realsoft too. So render specularity, reflection, diffuse, GI etc in passes and
combine then in compositing
program to achieve results faster than if U would have to render everything all
over if U would have to
adjust some certain element...

Hi Henri,
Very nice this little boy! Did you do the character animation with Realsoft?
Arjo.
