Thanks very much, Thomas :)

Yes, pigment patterns are awesome, in some way or another I generally use
pigment patterns in every image. Actually, I remember suggesting to you that you
use a pigment pattern to break up the paver reflections in your image "Paris by
Night - 1951".

I tried to search for that but the "this-site-only" style Google search isn't
working here right now for some reason (it used to, and not long ago). I looked
backward through all threads to almost exactly ten years ago and found these

Ah, yes! I do not remember if I used that after all. I shall check, out 
of curiosity. Thanks for the reminder!

A very nice work!

What was the whole "oval shield" thing about?

In France, you will see this (attached image) at the offices of notaries 
in particular. On thephotographof 1951, there is one.

I figured it out - but it is NOT like scale <-1, -1, 1>.
the quadrants are swapped by _translating them, and then the middle 
cross gets filled in to make the empty edges all nice and pretty.

I got the idea that this could be done using pigment {function{}}, and 
it actually _works_   :O

I have it half worked out, it's slow, and I still need to layer the 2 
textures to create the final infinitely repeatable tile, but hopefully I 
will finish that up after I get some other stuff out of the way.

I started modeling some new assets for an Earthlike planet-side scene I'm
working on. This is a "beam tower" that will be instanced several times, made up
of a few fairly simple UV mapped meshes. It uses cylindrical media with some
turbulence for the beam and lower glowy bits, and a spherical media at the top
of the spire for a flare effect where the beam emits upward.

And no, I'm not sure what the beam does exactly, but that's part of the beauty
of sci fi - it doesn't really have to make sense to us because we wouldn't
understand the tech anyway (but I suppose the guys that work inside these
buildings would know what it does...)

Here are a couple of test renders of the beam tower with materials in the
context of my basic planetscape.

Yes, that's it exactly :)

Of course all seamless tiles are still noticeable as being tiled when they
repeat too many times, but I usually use a pigment pattern to break that up by
using different scales and rotations within the map (sort of what I'm doing for
the ground plane in the beam tower material test renders, using a bozo pattern,
but with two different image maps).

Looks terrific on outdoor daylight!
