As before, the bottom 16 pixels are ignored in-game.

*EDIT* 100 posts! *EDIT*

Modified picture aye, cool.   The concrete looks great.

The only thing that looks odd to me is that the edges are chiseled pretty hard.   As for the colors you used in the second image I remember what your main color theme is so it makes sence.   Personally I would fade them some and make the over all theme dull, or seem worn, thats just my taste though, your choices work well too though.

So why are the bottom 16 pixels ignored?   Must be a different technique huh.

I know what you mean about the colours; I'm probably not going to attempt to age it, but I might dull them a bit - otherwise the yellow and blue might stand out, even in my texture set.

The game splits polygons at every 240 texture-pixels, so a 256*256 wall texture will get split into 4 separate polygons.  This is okay for the horizontal direction, since it tiles horizontally anyway, but it's a real waste for the vertical.  You end up with an extra polygon just for the bottom 16 texture-pixels.

To avoid this, you can take a 256*240 texture and scale it up to cover the wall (well, up from 50% to about 54% in my case).

The problem then is that any textures that are not multiples of 16 are sampled down by the game, making them look rubbish.

The solution is to make a 256*240 texture and add an extra bit onto it

The bases look good, the structure is WAY off. Any kind of material that looks so weathered would not have such 'clean' edges and cuts in it unless it were literally painted onto the wall.
