About selling my first model , help here !

You can just use Maya as your main content editing software and output an OBJ and FBX format for all other software. FBX would allow for standard shaders (textures attached if paths are leading to a maps folder residing in the same folder as the project file)

FBX support more features as OBJ, but both still have a lot of limits.
Most package specific features like holding stack (e.g. 3ds max) and that sort of things are not supported.

You can go as far as you want in supporting different software formats, but it produces a lot of overhead.

Regarding your legal question:
You can use logo's and brand names ore make copies of brand specific physical items, but the original copyrights owners of that brand/items can impose terms if they want to. You can only sell these models under an editorial license.

You would not be capable to hold full ownership of your creation in this case, you can be subject to legal actions from the original copyrights owners if they do not agree to the use of their intellectual properties and you would have to make deals with them to come to proper use arrangements.

People hoe buy your objects "under editorial license" know they need to be cautious, they can also be subject to legal actions from the original copyrights owners.

I just export the model, and put the textures in another folder too.

I only make models and no textures so far :) Good luck friends.

thanks guys , i thought for a start caring only about the mesh and it's wire frame , just to take it step by step

Does anyone know if CGtrader helps with that? I thought I read somewhere that if your models aren't in a specific format that they can convert it for your buyer at the time of sale but don't quote me because I read it on the forum a while back so things may have changed.

ok , can i sell my models that i modeled from another artist's concept ???
i know this seems controversial , but most of my models i create from other artist's concepts , it seems such a waste !

ok another question is how websites like cgtrader know if i uploaded the model exclusively or not ? i mean what if i uploaded the model in other websites "exclusively" do they search for the titles or images ? i'm just curious

and also can i publish the artwork that i'm selling in my portfolios , i mean i can freely upload the renders in websites' showcases , portfolios extra , right ?

Using the design of somebody ells to make a product and selling it without the original creators consent would generally be considered copyright infringement.

Websites like CGt cannot be hold fully responsible if someone uploads models that are in copyright infringement or not in line with terms of use regarding other websites exclusivity programs. However, if they receive notice from this, then they have the right to remove the objects and deliver account information to authorities.

In a normal situation you would best contact the original artist and tell him about your plan and come to agreements with him about how you are going to cooperate in selling work based upon his work, he then can make his terms. Probably claims a percentage of profit share (royalty's per sold copy) or sell the design and accompanying ownership/exclusivity rights (you would become full owner of the design).

Many 3D modelers would love to model nice designs of good concept artists. That is way I regularly make a call for an extended designers collaboration platform (a framework allowing for collaborative works). Artist would be able to work on individual basis from the comfort of their homes on collaborative project.

Until then, it will be relatively hard to fully benefit (on individual basis) from well trained specific skills, except when finding a good spot in a production environment, work freelance on a client basis or have a company specialized in selling 3D concept designs. (not everyone aspires this)

Ps. unauthorized use of creative work from someone ells can cost you dearly if you lose in court, so be careful with that sort of things.

I'm confident that at some point this framework for collaborative works will immerge, because demand for it amongst artist is strong (mostly in the field of independent games developers community).

okay guys , what is it with this price tags 99$ 59 $ 49.99 $ is it a psychological thing ? or something related to taxes ?
