But you won't be able to according to my experiments.

Who is going to do a SSLT sphere on a chequered plane?

far be it for me to buck tradition (checkered planes) but has anyone
tried the tiling pattern?

Mirrored (at the mid-point) color/texture maps work best

Not me. I'll probably wait until Bishop3D supports it after 3.7 is released.

It wasn't you who wrote that, was it?

May I suggest something like:

"For each pattern, each individual tile of the pattern has the same 
bevelling as the other tiles in that pattern, allowing regular caulking 
to be defined. For a pattern with N kind of tiles, the main 
colour/texture of the tiles are at x/N (with x going from 0 to N-1), and 
the extreme colour/texture caulk for these tiles are at (x+1)/N, the 
bevel covering the range between these two values.

Each tile has a side which is exactly one unit long. The tiles extend 
infinitely in the +y and -y directions and if no map is specified then a 
default grey map is used."

That may be wrong and an example would help as the maths is not easy for 
me to visulise.

(Everyone's a critic and you've done a power of good work on your own.)

nope ... lifted straight out of the change log (developers narrative)

no worries there Stephen ... towards the end of the doc adds I started
copping an attitude (several times almost walked away from it as I
didn't sign on to the project as a content "gardener") as I was
practically the only one doing anything. I just slammed it in, so I'll
work your changes into that passage ... btw: much better wording (proper
grammar etc)

Cheers

I have... and Pavement, too. Fun stuff. As I said before, lots of new 
stuff to play with. The tiling patterns will definitely add a new 
dimension to scenes that use strictly procedural textures. I like it.

Looks good!

Here's mine. Gratuitous sslt instead of your more subtle approach!

Wow, this completely passed me by. Excellent, I must have a play!
