GW Texture Paint

[Vor]

So, been working on a diorama base for my new Forgeworld Flyer today. It's now ready to be based, so I'm pondering the textured paint from GW.

 

From some youtube videos it seems to have gone down fairly well so I'm defiantly going to go with it, but I'm wondering how multiple versions of this paint work with each other. Since it's a large base, basic concept is it's a small rocky hill with a waterfall. I'm pondering using the following:

Stirland Mud - will cover most of the base
Lustrian Undergrowth - grass - idea is that it will go over the top of the Stirland Mud in places to represent the grass growing around the waterfall (thinking of using magic water for the waterfall)
Mourn Mountain Snow - will be used in small patches, representing the mountain snows melting as spring comes around
Astrogranite - will be used on rocks, cliff edges etc

I know I've not described it very well. Sorry. But I hope you guys have the basics of my concept.

Will they work on top of each other as I've planned? Is there a need for that? Or should I just do each section in it's respective colour and forget about layering it up?

edit: Guess I should point out, this is the first time I've ever actually done such a complex base. Most of my troops across pretty much all my armies are not even based at all yet.

Take a look at the Vallejo textured pastes. The initial cost is more but the tubs are huge and there's a large variety of textures and colours. I use the grey pumice one. They are a resin paste which cure fairly solid and paints up really well.

It's all the same crap. Individually it'll look passable, but together, it's just going to look like the same texture but differently colored in certain areas. Like stated, Vallejo has a variety of textures that simulate different terrain far better than the GW texture which is all identical. The problem with mixing Vallejo is that they come in huge jars.

Stirland Mud looks great when it's wet, but when it's dry it doesn't look like mud. I suppose it looks mud-like if you don't give it a wash or drybrush. 

 

Astrogranite is the best one of the bunch IMO.

 

For jungle, you are better off using tufts or grass.

 

For snow, you are better off using crushed glass snow scenics, or baking soda if you don't mind the more powdery look. Otherwise you will just end up with white Astrogranite/Stirland Mud/Lustrian Undergrowth.

Try the cracked earth effect paint.. Agrellan earth.. That would probably simulate a dry riverbed of cracked mud better than the textured paints...

Found this a bit late, but you can get a nice mud effect using the texture paint, washing it with agrax, then applying a watered down layer of ardcoat. Gives you a nice wet gloss in the dark recesses, and a dry light look on the raised areas.
