Setting static objects inactive/invisible?

[DRedshot]

Ok, i've just had a look at the decals folder and it's layed out slightly different than I expected. I thhought the setup was the same as in the entities folder, but I was wrong.
It doesn't matter though! I'll edit step 1, and make a step '1.5' in the list above, which is:

1. Go to redist/entities and make a folder called w/e you want. (My_Entities for example)
- Inside this folder make another folder. (Call it Decal01 for now)

1.5. Go to "redist/static_objects/decals/" and look for the .dae filename which corresponds to the decal you want.
- for example, if you wanted the "blood_pool_static" decal, you would select "blood_pool_static.dae"
- Copy this file to your Decal01 folder you made earlier.

Edit: Oh your file isn't in the static_objects/decals folder, that will make it a bit more complicated because you'll have to make a plane for the texture to be mapped onto in Maya. (basically make the dirt_coal.dae file yourself)
Would you be able to choose a decal in the static_objects folder instead?.
