Ok I have the V3 and m3 base characters the free downloads.  I am purchasing http://www.xurge3d.com/inc/sdetail/5416  the ahev body suits for m/3 and v/3.  Now my question is this:
are the V3/M3 Head & Body Morphs
http://www.daz3d.com/i.x/shop/itemdetails/-/?item=3010 a requirement to buy other poses and morphs?  For example lets say that I find an alien morph that I like real well for v3 can I just buy that figure and use it with my base figure or is the morph pack a pre-requisite?  Do you guys strongly suggestion buying the base head and body morphs? I'd like to just buy the morphs for the characters I want to change them into as oppsed to having to shell out the extra cash sorry I am confused
jeremy-

The Xurge outfit can be used with just the base figure no morphs needed.

However, if you want to buy or download any number of the free character addons for M3 and V3 then you have to have the head and body morphs for each of the figures.  You can buy them together in a combo pack for cheaper than you can buy them separately for each figure.

If  you buy or have a free character addon but no morphs installed, then all you will be able to do is use the textures from the character addon packages, not the morph injections.  The "morphs" that are in character addon packages are injections, not the actual "morph" files. These injections rely on the morph files from the Daz morph packages in order to work.

Hope that helped.

Here is a link to some information I have posted for new users to Poser.  It might help to shed some light on some things that you may be wondering about.

You don't have to buy them but you'll be limited in what you can do with the figures if you don't. Every render you do with them will look exactly the same for a start.

Some figures require them, some don't. It depends on whether the figure creator used the morphs to make their figure. Most do, because it's the easier way, but not all. And not having the morph packs does not mean all your characters have to look the same.

For example, Blackhearted's Girl Next Door morph does not require the morph pack for V3 because it is a hand-tooled character based only on the base mesh, and it doesn't look at all like the V3 base. But this is the exception rather than the rule.

Also, if you plan on creating your own characters using magnets or a 3rd party app like Blacksmith, the morph pack is not necessary.

Any character for sale should specify whether it requires the morph packs or not. On DAZ I think they all do, but here sometimes merchants leave out that fact. If you're looking to buy a character and it doesn't say it requires the morph packs, check with the vendor first to see if that's actually true.

Poses do not require the morphs (assuming that you mean posing as in moving the figure to a new stance, such as sitting or running).

As mentioned, not having the morph packs limits the degree of character faces and body types you can use from merchants and freebies. Some merchants sell characters that do not require having the morphs packs, but you'll have to read the product description carefully to be sure. A few freebies similarly do not require the morph packs, but most do require owning them.

Poser 7 has a morphing tool that allows creating your own morphs directly in the application. Magnets are another means to alter figures in Poser. You can create your own morphs in other 3D applications. This means that you do not need the official morph packs to sculpt your own characters. However, there is some convenience to having sets of morphs already designed to make the most common changes to the figure and to apply wholesale changes to the body (such as thin or muscular). There is a certain satisfaction to creating your own characters.

You've got a lot of options to consider including, if you decide to buy the morph packs, whether it starts becoming cheaper to join the DAZ Platinum Club to get a 30% discount on the packs. Another consideration is that the newest version 4 set of Millennium figures are also coming out and, if Victoria 4 is an indication, morphs will be sold in one pack instead of as separate head and body packs. It will be years before there is as much free content for V4 as for V3 and the V3 model is still a very useful figure.

Thanks alot you guys I just went ahead and bought both head and morph packs for v3m3
just cover the basis.
