It’s less of a question of How much it would cost , rather than,.. is there someone with 3D-Max, Daz Studio, or Poser, and the clothing who also has the free time to do this for you.
The next part is a legal issue of the “licence to use the products”,
Unless you buy the Models (clothing is also a model) then you don’t have a Licence to use them. in any software, and so, someone else can’t put it together and send it to you.
Poser Pro (if I remember correctly) Has a Link to 3D Max, which means that you can create a scene in poser pro with the 3D human model, and it’s clothing ,.. then send it to 3D Max to render.
Poser also comes with a Bunch on models and clothing,. and 99% of the Daz3d models and clothing sold in the store here will load into poser.
Daz Studio comes with the new Genesis figure, which is different from previous figures, like Victoria 4 and Michael 4. (which will both work in Poser.
Victoria 4 and Michael 4, are also supplied is OBJ format which can be loaded into 3D Max, although, you would then need to load in and adjust all of the texture maps for the figures to make them look better in 3D Max.
You’d also need to rig that 3D model with a Max “Biped” and skin it to work correctly,..
One main advantage of Daz Studio that you’d loose by importing and re-rigging the figure in 3D-Max, is the ability to have the clothing automatically conform (Fit to) the figure, and move along with it.
Daz Studio allows you to load the Model , Add the clothing (fit it to the figure), add hair, easily change the skin textures, clothing textures, or hair textures, and then animate it using simple to use tools, or pre-built (customisable) Motion capture animations.
A lot of the work you need to do, depends on what you actually want to do,. if it’s a still render, then that could be done in Daz Studio.
If it’s an animation you can also do that, and render it out with a transparent background, then composite that into a 3D Max Background.
My advice is to download the Daz Studio 4 software, while it’s still available for free,.
then play with it,. see what it does, and see if it’s possible to do what you want to do without having to jump through a load of Hoops to get it into 3D Max.
There’s also Daz Carrara, which is similar in many ways to 3D Max, It’s a Full 3D modelling texturing animation and rendering program, but it can use Daz3D and Poser Models in the same way as Daz Studio or Poser do. you may want to have a look at that too.
there’s a 30 day (Full PRO version) available on www.Download.com
Hope it helps.
