For a new scene, I have been working on a peeling paint texture. What do
you think?

Nice.
A bit too much peeled, assuming the paint is red.
The cracks are fine.
can you reduce the white big area, while keeping the cracks ?

The code is a bit messy at present, but I work towards a macro that will
enable the whole range. For instance this image.

A first version of the macro would yield this.

lovely.
The red is paint... crackling, peeling. So real.
The green might be interesting for moss if a quick gradient is available
at the boundary... give me a finger, I take the whole arm!

My final macro (for the time being?) gives the following output. Paint
can be peeled from 0 to 100%.
I shall post the macro in p.b.s-f. Usage is included.
Enjoy!

To me, moss would need a different kind of macro...
I have not done it (yet) but you might want to use the macro in
combination with a proximity pattern.

The cracking looks great. It doesn't look like it's peeling, though. (PeelED,
yes; peelING, no.)

So, improve it. Thomas has given us a starting position.
Don't criticise, improve

Thomas asked us what we think; what was I supposed to say? In order to improve,
one must know what to improve. But the way I saw it, this is Thomas's texture,
and I was leaving it up to him to carry it in whatever direction he desires.
Racking my brain a bit, I recalled the cracked mud in "Age of Innocence"
(Cathy's World). Perhaps the peeling effect in that texture can somehow be
merged with the cracked paint texture.

Yes, to me it is peeled. Peeling needs another dimension. It is very
good as Thomas's textures generally are.

Aaahh... I would like it to /peel/ indeed, but how? The peeling should
follow the texture. I have experimented with some mesh generation but
that remains totally unconvincing.
Your mention of Age of Innocence is correct but that will not work here
and it only concerns the cracking not the peeling.
I need somebody smart... ;-)

Thanks Stephen. As said above, the peeling is the most difficult part
and I do not know how to do that presently. However, I am quite
satisfied with the texture :-)

It is a challenge for all of us ;-)
Somehow, I am certain there is somebody somewhere who would know exactly
what to do...

It is maybe a bit too soon, but I would like to show what the texture is
presently used for.
I have taken as a working basis a photograph by Urbex (Urban
Exploration) photographer Daanoe (http://www.daanoe.nl/en/): German
Hospital aka Red.
The scene is heavily under construction, not in the least because
degradation of structures is quite difficult to achieve in a natural
looking way.
Staircase, outside pavement, and outside wall, are macros by Chris B.
The building is mesh2 using Silo.

Well it is a texture and it looks great in your hospital image.
We cannot expect lifting and curling of a surface to be more than an
impression unless the surface is actually uneven. Normals help but
shadows and edges give the game away.
Your texture works perfectly in your dilapidated hospital.

Indeed. And yet, as I constantly compare the image with the original, I
feel the need for curling edges, especially where you expect their
shadows to be. I would like to go beyond the texture.
Maybe I should do something with EvalPig()... I am stuck, no doubt about
it :-)

I don't see how it can be faked. The Mesh route is too mich, I think.
Do you think that it would be possible to throw triangles at it using trace?

Faking is impossible indeed as far as I can judge. As a prove of
concept, I have written a macro that draws little triangles randomly
down from a surface, but that is totally ugly. I wonder how one could
trace the paint boundary and place little pre-made peels of paint there,
correctly oriented of course ;-)

Nice texture, It remembers somehow the one I used for an old IRTC entry.
My start point was a tutorial of Alex Ivanov (the link seems to be no
longer active).
