Hello everyone.
Right now i want to create a character for my possible game(not sure if there will be any). And i don't really know where and how i can do this. Looking for advice.
Should i try in Daz3d or download/buy something else like Hexagon or Zbrush? If allowed, could you provide links to tutorials?
P.S. I'm sorry for my bad English. Due to the lack of practice, it is hard for me to write and speak it, but reading and listening is not a problem.
Your English is fine - don't worry about it.
To answer your question properly requires a bit more understanding of what you're planning to build game-wise. The main distinction is whether you're planning on building a game that uses 2D images using something like Ren'py, or whether you're going to try to build something that's "truly 3D" like The Twist or House Party.
The 2D image approach is a LOT easier, of course. In that case, Daz Studio is probably a good place to start experimenting. There are quite a few free assets for it, which means you could basically just start with a pre-made character, hair and clothing and go from there. If you'd like to have something "custom," then what you can do is look at the many morph packs that are available for Daz - these allow you to reshape the character by adjusting more-or-less obviously-named parameters (nose size, breast size, whatever.) (There are also a lot of paid assets for Daz Studio that have been, well, "shared." See the "Asset Releases" forum here, for example.)
The big question is "once you have your character, how are you going to use it." Daz Studio allows you not only to design and pose characters, but will also do the rendering for you. So if you want to use it, you'll generally want to use assets that are compatible with (designed for) Daz Studio. (And there are a LOT of them.)
If you're going full 3D, then you're probably going to use something like Unity. That means you should be looking for Unity-compatible characters. There, MakeHuman is probably a good place to start.
Jumping into something like Blender or ZBrush is definitely possible, but there's a MUCH longer learning curve there, IMHO. Modeling figures from scratch, or even editing their meshes, is a special skill that a lot of people don't have. (I certainly don't.)
There are also packages like Honey Select. I don't have any experience with that, so I can't say much about it, but I know that many games here have been done using figures from it.
