Removing blood decals on certain models

I am developing a game mode with my friend and I need help with removing blood decals. It is ruining the concept of the game. I would prefer not to make a custom material for this and just use the games crap. Just on player models. Don’t want to use r_decals or anything related.

Put $nodecal “1” in their VMT file.

I did not want to do that I’m saying. But I just will until I find a better solution.
