After trying out black mesa source I decided that the game has a lot of replay value, I missed many things and there are still achievements, but still the #1 thing which annoyed me the most during the game was the blood stains that you get on your hands and/or weapon when you kill an enemy. Here's a picture for reference: enter image description here

Is it possible to remove it? I think it's so messy and unrealistic, and I completely despise this effect. I've looked around the settings but nothing seemed to disable this effect. I'm pretty sure it can affect performance as well.

  • It disappears after a bit. I don't know if there even is a setting for that, though.

  • It does disappear after a minute or two, but you never stop killing, so the effect lasts for a very long time if you're in the mood for action :(

    I highly doubt a few extra small textures will "affect performance" in any noticeable way. Commented Sep 18, 2012 at 2:45
  • Source games are quite moddable, so it may be possible in theory even without a settings option, if you have the modding knowledge to find the right file(s) and make the right alterations. Commented Dec 21, 2012 at 16:28
  • This effect was a terrible let-down for me when playing, I was getting blood stains when shooting an alien with a pistol at medium range, that was weird, not to mention the blood stained guns look weird, as if a decal glitched all over it

No I don't believe you can disable this effect.


Just type

cl_mdldetailfx_enable 0

into the console.

I had the opposite problem, stains didn't appear at all, but I have re-enabled that by setting cl_mdldetailfx_enable 1
