I need to smear blood on some walls (for a shot).
Do you have a favorite resource? I know about ActionVFX & FootageCrate.
Stills are fine, no movement neccesary.
Thanks,
Ted
“For a shot” 
“I need to smear blood on some walls (for a shot)“
“For a shot,” sure it is…
Get yourself a hunk of foam core, some chocolate syrup, your hand and a phone/digital camera 
(or maybe just a Paint node.. but then there’s nothing to lick afterwards)
I always shoot my blood elements, I have both venal and arterial fake blood
AI those blood spatter elements. It’s surprisingly good at this kinda thing.
