this is the convar used to disable the blood-on-screen effect
on low health:
PHP Code:
// <1/0> = enable/disable displaying blood on the screen on low health
// -
// Default: "1"
// Minimum: "0.000000"
// Maximum: "1.000000"
dod_basicgore_lowhealthoverlay "1"
Just edit the config file and set it to "0" and that part of the plugin
will be disabled
