According to Google Translate:
Hello, Good afternoon.
I am Brazilian, I'm sorry, but do not speak English. There are times that try a "mod" that causes my vampires do not die in the light of the sun I did not want to be perfume or other temporary object. I wish it was optional even definitive. What if I choose it, my vampires can walk in the sun all their lives, without suffering damage. If you can create this "mod", I thank you very much!
Basically put, he's looking for/requesting a mod that lets vampires go outside without suffering any damage.
