Is the vampire power not working in day time?

Hello, my vamp sim was so thirsty after work. He tried to do 'drain life spirit' after 7 pm but the sim suddenly refuses.  I tried to do this in the morning time to 4 to 5 sims near grills but only one offered his blood.

If your vamp is failing at compelling others etc then either wait until night or bring the sim inside and try there. If you need to bring an uncontrolled sim indoors so your vamp can drink either invite them to a community lot or try the 'sit and chat here' interaction by clicking on a sofa inside your vamps home.

@Playalot  Ahh thanks. Yes I tried this all outdoor under the sun. Even my vamp sim doesn't have weakness point related with sunlight. I thought it would perfectly work under the sun in day time without weaknesses of sunlight. Also my vamp sim has 3/3 sunlight immune.

It was the tip from Vlad when my vamp sim was growing vampiric power that Vampire's power is very weak under the sunlight. I thought it was because he had the weakness about the sunlight. Now I totally understand what he said.
