Ok,the title may be a little misleading. I wanted to ask f anyone knew of a way to make things stay longer in Half-Life. Like spent brass, blood, corpses, decals, etc. I know it’s possible, Half-Life Uplink Extended had almost all of these things, at least, the shells seemed to never disappear. I looked every where for a way to do this with no luck. So, can any of you help.

I’m pretty sure old decals disappear as new ones show up, this goes for blood too, so mp_decals with a really high number should work. I’ve never tried though.
I know that, however, I’m sure my rig just might be able to handle, mabye. 
Someone’s forgetting what year we’re in…
