daz studio is free. could i use it to model for 3dgs and then export into 3dgs or a format that 3dgs can import??

no. you can't model with it, neither can you skin, texture or animate your own models with it. it's an animation and rendering tool for poser and daz models/content which mustn't be used in games.

Yes, you can animate your own lower poly game models with it either manually or via BVH (which Studio imports) and you can export to OBJ or purchase their FBX exporter for use in 3DGS (although I don't know how reliable that plugin is). It's simply a matter of preparing a model (see below), and importing it.

You are also allowed to use any 2D output (renders used for sprites or whatever) in commercial applications.

If you want to model and skin/texture, you can use Carrara and MAYBE Hexagon 2. I'm guess Hex has an exporter given it's th same company, but I'm not sure. If you're clever you can rig your model to work fully with Studio's tools, and create many variants from some general purpose models via the "pulling" and "pushing" sliders just like when you are creating a custom character from Daz content.

You actually can model (limited only ny yourself) with daz using the primitive and d-form tools included with it. Then export as an obj.

I use Hexagon as modeller but I export the mesh as obj and separate texture (that I refine the texture later).
Hexagon is very easy to use and one can model something without any previous training ( obsviusvy professional modelling does required pratice, time and talent , even for a really intuitive software like Hexagon) .

@Brat, do you own carrara? i do. so i know what i am talking about. for those who don't know,

http://www.daz3d.com/i.x/software/carrara/-/comparison?

carrara can only IMPORT poser and DAZ studio files. there's no direct pipeline between carrara and DAZ studio. there's no need to, btw. if you own carrara, it can do all things better than DAZ studio, it even offers a built-in fbx exporter and x exporter.
and you can NOT rig your models with Studio. you have to use preproduced content that already carries bones. obj import in studio is practically unusable. try it.

@dragon, don't always repeat what's on the feature website. try it and you'd know that this dform thing is similar to a patch modifier, it is not really able to serve as a modelling tool, it's only good for raw deformations.

don't talk about things you obviously never used.

depends on what you call modelling, judging your website. if you knew carrara you'd know that it does not offer a native daz studio export. btw, it's pretty useless to recommend a $549 application just as a bridge for a free one, even if it were possible.
and i doubt you ever got an animated model from daz studio to MED in a reasonable way, including skins, anims etc. and a legal way, as it is stricly forbidden to use any of the (free) DAZ content in your games.

not_me, i warned you. you will be disappointed. believe what you want to.

never said you were allowed to use the figure models in your games. wouldn't want to anyways as they are to high poly for 3dgs to use, what i did say is that you can model with daz(and i don't know what that hs to do with my website you arrogant little twerp). Oh and by the way people that use dxstudio use poser and daz content all the time. and native daz is obj. which my carrera does export, and if you paid 549.00 for carrera (i paid less than 50.00, and yes it is a legal copy bought from daz)than i feel sorry for you.

watch you language. i'm not interested in the way dxstudio user handle it.
if you paid less than 50 for your "carrera", i guess you have the express edition wich can't even do bone animation nor export to any useful format. congrats.
