heheh, thank you ^^
I use Apophysis 7x

do you usually zoom in or zoom out?
and how far do you stretch the variations

I prefer to use scale instead of zoom, since it does about the same thing, but with zoom it increases the render time if zoomed in. And it depends, I usually leave Scale at 25, but I might mess around with it a little to see if it looks better with a higher or lower scale.
If you mean how much do I stretch the triangles, I usually leave them how they are, just seeing how they look if I change the size. Or if you mean the actual variation amounts, usually play around with them, see what happens with small increases like .3 or .5, or see what happens if it's changed to a negative number

yeah i know what you mean,I usually put my variations in the negatives, it makes an awesome effect

Now in 3D!
