Daz Studio is a free program and they do give you some things to get you started. That's all great but you will probably want to start buying additional content at some point. And that is where Daz really makes its money. That's fine too. Hey, they are in business to make money and that is what business is all about. But it doesn't meant hat you can't find ways of saving money on content.
If you really plan on buying a lot of content over a long period of time, I suggest you become a Platinum Club member. Believe me, the amount of money yo will save will save you muich more than the cost of the membership. It more than pays for itself.
Another thing you will want to do is check the Fast Grab section to see what is on sale. That is often where you can get some of the best deals. Between Platinum Club membership and Fast Grab alone, I have saved so much money on content purchases. So much that I can't even begin to calculate the total savings.
One thing is to try to never pay full price for anything. Almost everything that is sold on the site eventually goes on sale at some point. You just have to be patient. Just add the items you are interested in to your Wishlist and check your Wishlist regularly to see if they are on sale.
Try not to buy anything until you need it. Concentrate on certain themes. I started with buying content for the purpose of doing Western Themed art. After that, I started to buy pirate themed content. Then I moved on to other things like fantasy, horror and cartoon. the list goes on now.
There are some things you will probably need no matter what themes you want to get into. For example, morph related content. That allows you to create a variety of characters. That is much better than just using stock characters. Each generation has morph sets. Generation 4, Genesis and Genesis 2 all have them. Each also has Creature Creator Morph sets. That works great for horror or fantasy.
Each month, there are usually specials of some kind on content. Also, there are always new releases and usually you can get a new release at 30% off. If it is an Item you really want to use, that might be a good time to buy it.
You might want to get all of your base characters first. Then expand from there. I started with the Genesis base characters. That included Michael 5, the Freak 5, Victoria 5 and so on. Then I started to get the 4th generation character bases like Michael 4, Victoria 4, the Freak 4 and etc. Sometimes there will be specials on character bases for a certain generation of characters. Maybe this month will have the genesis characters at 50% off or better. Maybe next month there will be a special on Genesis 2 base characters, which will include Michael 6, Victoria 6 and so on.
There are other sites that sell content that can be used in Daz Studio or Poser. Two that I like to go to are Renderosity.com and RuntimeDNA.com. When I add something to my Wishlist on those sites, I will get an e-mail notification when they so on sale.
So being patient can save you a lot of money and timing is everything. I hope that you can take some of these suggestions to heart and save yourself a lot of money. Good luck.
