There are different ways through which you can do this crafting of 2D into 3D like of scalling, shearing. https://errorcode0x.com/fixed-dell-printer-error-016-302/ helped me to get the best way to do this.
The reason this hashtag started was that there was a guy in Japan criticized the company behind pokemon(gamefreak) saying that their 3D artist are useless. and skilled 3D models would be able to be made in 5 minutes. He mentioned that you can do 800 pokemon each in 5minutes so close to 60 hours will be only needed. and if they can't do that, they are not worth the salary. and 3D modelers took this as a challenge. Resulting in 3D modelers doing modeling / sculpting in various 3D software.
Don't know if you're still having this issue but it's fixed by enabling "Specify Manual Texture Size" and then playing with the "Manual texture size" input until it seems right.
Airborn Studios has presented a free guide on the baking process within Marmoset Toolbag that will also help you through the hoops of baking for another 3d software like Autodesk Maya.
The studio has been using Marmoset’s baker on a few projects, including Halo 5 and Overwatch. Stefen Unger wrote this guide in late 2016 for internal use only with the most recent update done in February 2017. It might not be perfect for your workflow, but over 40 pages of tips and tricks will definitely guide you through essential steps.
