Hmm.
Just for the interest of those following this thread.
Note I've updated this to better explain what I've found while fiddling with these textures, and I'd forgot about one of them too

.
There are 5 textures relating to the ground. Two are grass (StadiumGrass1 & 2), and 2 are dirt (StadiumDirt1 & 2), the 5th is StadiumGrassStripe.
The 2 dirt textures mix on hills and flat parts inside a fence. StadiumDirtMAsk which gives the tyre mark effects sits on top like a shadow. The image is stretched over an area of about 4.5 blocks square. You can mod it like any other files if you wanted other patterns.
The 2 grass textures mix on the field at soil level, and therefore sit under the grass. You can see it as you approach the stadium edges where the grass stops and a flat surface starts. StadiumGrassMask sits on top of grass and soil like a shadow effect. Again, this image is stretched over an area of about 4.5 blocks square. Its generally a grunge texture but you can add patterns to if you wanted.
The other way to add a texture to the actual grass is to use a big texture called StadiumGrassStripe which is stretched across the whole stadium area. No matter how small you crunch the pixels on this file they become large when stretched. They also affect the ground textures too but are more noticeable on the grass which tends to hide the soil level textures. A good example of this is on the Aqua mod. Look it up.
And so..
I'm finding eie's descriptions of what he wants a bit confusing compared to how I see the files.
And so, interpreting them the best I can,
1) I've grunged up the grass textures 1 & 2 (with noise) and colored them to match (almost) the dirt textures. I've also used similar noise textures on the dirt 1 & 2. The tyre marks still show, which I think is cool, although I could remove them.
Than I've reduce the noise clots on the StadiumGrassStripe and reduced its contrast so that it blurs slightly to mark the soil but isn't so obvious.
I've removed the grass completely, because it hides the two grass (soil) textures.
eie can add the grass back himself just by replacing my StadiumGrassFenceD,dds with the default texture, but it would hide the 'noisy' ground.
2) Booster texture and enginekill texture updated as requested.
3) Cloud texture updated.
Sorry I'm a bit late but I've been busy these last few days with a few other builders mod queries, and life in general.

If there is any interest from the wannebe modders out there, or modders unsure of more complicated graphics thingy's. Start a thread, call it 'Ask that popgun bloke' and ask the questions. I'll answer with as much detail as I can.
eie, comments when ready.
