Footstep sounds, decals and puffs in TGEA 1.8.1.

I'm pretty new to 1.8.1 (aren't we all) and I couldn't find any info on this, but I was pretty sure propertyMaps weren't used anymore.
After looking in the engine I realized it's now part of the material and has been expanded a little.
Basically in your materials.cs when you define a material you add these:

showFootprints =true;
    showDust = true;
    effectColor = "0.46 0.36 0.26 0.4 0.0";
    footstepSoundId = 1;
    impactSoundId = 1;
    //customImpactSound = "scriptsandassets/data/sounds/custom_mono.ogg";
    //customFootstepSound = "scriptsandassets/data/sounds/custom_mono.ogg";

so your material should look something like this:

new Material(bproad02)
{
    mapTo = "bproad02";
    baseTex[0] = "bproad02";
    bumpTex[0] = "bproad02_NRM";
    pixelSpecular[0] = true;
    specular[0] = "1 1 1 1";
    specularPower[0] = 16.0;
    //FootSteps and Impact    
    footstepSoundId = 1;
    //customFootstepSound = "scriptsandassets/data/sounds/custom_mono.ogg";
    impactSoundId = 1;
    //customImpactSound = "scriptsandassets/data/sounds/custom_mono.ogg";
    showFootprints =true;
    showDust = true;
    effectColor = "0.46 0.36 0.26 0.4 0.0";
};

and that works great as long as your animations have triggers.

My question is this, how would I get this to work on Atlas?
What would be the texture I map to and do I need to add an Atlas object type in the engine?
Is it that easy?
