Original Headshot Blood?

[sharp]

Hi, I have a question,

How can get headshot blood on my server? I mean by the original ones (with out blood plugins). I can get headshot blood when I play with bot on my own computer , but not on my server (include the server I create at home for testing) hlds.exe ..I've done lots of research on it.. but still cant figure out why...

I've tried all the following commands..but it works only when I play with bot on my own computer :
mp_decals 300
r_decals 2048 (or 300)
r_decal_cull_size 1
violence_ablood 1
violence_hblood 1
violence_agibs 1
violence_hgibs 1
r_renderoverlayfragment 0
