TF2 Blood Mod problem.

Hello there,
I have a mod for Garry’s Mod changing the default blood to the TF2 blood effect. But, as you can see on the picture, it only changes the blood effect on props/ragdolls. The map’s floor/walls stay unchanged. I’ve already looked thorugh the HL2 Materials gcf to find out whether there’re more materials to overwrite, but with no result.

So, does anybody know a solution for this?

I got the blood mod from garrysmod.org if this is relevant.
