Trying to port L4D2 blood decals to GMod... OH GOD PLEASE HELP ME

So I’ve been trying to port the L4D2 blood decals, and this is how far I’ve gotten.
I used GCFScape to get them, and first I just tried dumping them in my garrysmod/materials/decals folder.
That of course didn’t work, and my blood decals suddenly were messed up. So I undid that.

Then, I used the Horror Blood mod as a base (http://www.garrysmod.org/downloads/?a=view&id=54631) and got somewhere.

At this point, Only SOME of the decals worked. I’m not sure how to explain this. I opened the decals from Left 4 Dead 2 in VTFEdit, and saved them over their corresponding decals in the mod. (I saved blood1.vtf from L4D2 over the one in the mod, and such with the others.)

Now after this, I ran into a problem.
Some of the decals in the mod were a 256x128 resolution, or 128x256. When I used the 256x256 decals from L4D2, they would get “cut off” so to speak (In GMod it would only show 256x128 of the decal instead of the full thing).

So I want to know, what do I have to do to get the decals to display correctly? I’m guessing it has to do with the .vmt files (I read the valve developer wiki on it) but I lack the skill to fix it.

Isnt the L4D2 blood the same as the L4D blood?

Oh, didn’t see that. But I got it working. http://www.garrysmod.org/downloads/?a=view&id=115252
