Hi, I'm a beginner with povray and moray, and have a question.. =)..
Is there a way to avoid the shadows that are when you for example
cut out something with a cylinder or sphere? Povray makes a shadow as if
there was a cylinder or sphere there, when I actually are using a CSG
(difference I think)..
help!!
bye

I think you misinterpreting something there, you problem must be something
else.
If you have a CSG difference where an object B is cut out of an object A,
then the only thing will be the rest of object A (the part not cut out).
There will *not* be a shadow of the invisible object B.
Maybe if you explain a bit more on what you do and see?

Ok, I'm creating an ashtray out of a cylinder. First I cut out a big hole in
the cylinder for the ash to be in, and then I use small cylinders on the edges
of the tray for the smoker to put his cigarette in. Kind of half-circle
cutouts (hard to explain, I'm not an expert in english language as you may
have noticed).
Well, I illuminate this pic by placing a point light at the camera, and when I
trace it, a shadow of a cylinder falls in the tray, where there should be a
hole.. hmm would you like me to send the file to you?..
Thanx,

I checked out your model. Actually, everything is fine! There is no shadow
in the model!
What you think is a shadow of the front-edge, is in reality a *reflection*
of the back-edge! Try the object with a texture without reflection (simply
delete the finish in the texture) and you will see the "shadow" vanishing
:-)
Happy to help,
Johannes.
