Thanks Alain and Darren of suggestions.

Thought I'd share what I have so far. I'm getting some artifacts with the 
glass container, and the upright connectors (lathe objects), perhaps my 
Bishop skills need further development. I DO have sturm on  but don't know 
where they (artifacts) are coming from ... perhaps viewing angle, or 
lighting angle

line with the horizon. I wonder if changing the orientation of the scene 


one block through to another. You can add a degree of randomness (if you 

Nice modelling BTW. Is the shape of the hourglass from RL?

thanks for the tip ... I'll give that a try!

ha-ha ... yes the texture was just a quick and dirty effort for now,
I have a little random routine that I had not cloned from another scene yet!

yes ... it WAS in the shop last year and didn't sell. I liked it so it's on 
my desk now ;-)
I'm having a good time with Bishop and I like it. Modelling in general is 
hard and it takes a lot of patience. I've also had to get in the habit of 
saving more often especially when I finally get something looking like I 
want.

random variation to the objects, for a while. Also a tab to translate 
the texture would be useful.

attractive, though.

countryman StephenS, guiding its development. Wait until you try the 
animation features ;)

Hint: When you save a scene the last save is renamed as MyScene.bak, so 
you can revert by renaming the extension to .bsp. Also, I like the Undo 
Multiple feature.

I had camera y and look_at y the same. A couple of degrees of x rotation 
made most of the artefacts go away, the rest appear to be ripples in the 
lathe shape itself. I imagine a few more strategic points probably wouldn't 
hurt!

Actually Thomas deG once recommended that you should roll the camera a 
bit, for artistic effect.

That sometimes helps as well ;-)

hehe! Indeed...  :) just a couple of degrees.
It more or less simulate the fact that nobody is holding a camera perfectly 
level. And it adds an extra, unconscious, tension to the image that is 
difficul to trace back to its origin if you are unaware of the trick.
