*Update 06/11* BoilingOil have made an improved version of the wall overlays : available here ('ll try the updated the meshes in this very thread asap but it won't be possible before August 2011.)
* The overlays were originally sold at §30, but were mostly used for adding cracks, smudges and filth to walls... things that would normally LOWER the value of a lot. So he made them FREE. (much more logical!)
* Room score was removed (adding cracks and graffs is not really improving environment !)
* As wall hangings, the overlays are considered art-work: sims will view them, comment on them, and approve or disapprove of them as if they were precious works of art! A damaged wall doesn't deserve such attention... So he found out how to disable that!

For those who want to learn how to make such changes themselves BoilingOil has written an article Please have a look

Hi,
Animations, when placed on any existing walls will add moving "things" to it, while overlay will add "enhancement" such as graffs, torn posters, cracks, dirt, holes or blood splats. Or anything else you can imagine and draw...

A full heigh 1 tile or 2 tiles poster with animated or non animated recolour, the Mesh is static. It has its own GUID.
The polycount is minimum faces: 2 Vertex: 4. (The smallest possible object !)
It is base game and Ep's compatible, thanks to Numenor.
Can be found under decoration/painting

If you like to place the poster without to pick it each time in the catalogue, hold Shift while clicking to place an object

I didn't make this object, it's a gift to everyone from Numenor, passing through me, so all thanks and credits goes to him.
I'm only responsible for the recolours.

The Degradation Kit !
wall overlays to give your walls some history to wear...

Graffiti
Various tags, graffs and stencils. A light transparency has been added to allow the underlying pattern of the wall to be slightly visible. N°14 is reproduction of a Banksy's stencil at real size. Make your own tag, now!
Urban Art everywhere yay !


Posters
Some people glue posters, others tear them apart. Both are unaware that, together, they create beautiful abstract art pieces.


Degradation
A serie of crackles, scribbles, holes and dirt. Some walls are responding better to the treatment than other. You'll find out.


Bloody
Several Blood splats for gore fanatics, works better on walls with light colours.


Animations

Laser Beam
Security laser beam with subtle movements.

SIMatrix panel
Really moving Simlish walls in a matrix style.

Alien Wall Diseases
2 totally useless (and therefore essential) and ugly animated "things" from outer space. It's breathing, it conquered the wall, it's alive ! (the texture used is pretty big, so watch out, if you plan an invasion with many creatures, that it doesn't bug your computer)


N.B. : The animations will only work in life mode, it won't move in building or buying mode.

Installation
Place the "1tile-ThankyouNumenor_MESH", "2tilesThankyouNumenor_MESH" and the recolors you like in your Downloads folder.
The thumbnails will appear with coloured background for easy sorting, but the objects are transparent.

To have it fully working, you'll need to send a loving thought to Numenor, I like to have him flooded with positive vibrations , so help me out people !

Recoloring
You're very welcome to make your own recolour and share them ! You can add the original mesh in your lot upload, a link directing to this thread is appreciated. Thank you.
The template is needed for making animated recolour. Along with the template, a little recolouring guide has been provided, please be sure to have a look at it.
