Hair can be made through transparence maps and flat plains. Enviroments are too vague.
Please go into further detail with your request, read the manual, blah blah blah.
Are you even reading this? There's a point when these threads just get ridiculous. It's not like NO ONE on the website has EVER asked these questions. They're so general it's a miracle you didn't find help on the first page. Read for someone who asked your same question before you ask it. Otherwise you're just asking the same question over and over again. This is becoming very spammish and annoying.
I'm sorry If I come off as being too harsh, but there are people who are actually trying to do what I'm describing. They're looking for threads whith answers to their questions. That can be hard to do with thousands of threads asking the same question bunched up together.
All I can do to help you right now is direct you to the manual. It shouldn't be hard to see, it's to your left on the screen. Take the basic concepts you learn from those, and bend them to your needs. Only when you learn how to do this will you master the program.
