To answer your questions, it can seem complicated but I'll keep it as simple as possible. When you purchase a 3D product to create renders, it comes with a single user license that gives you the right to use it for the creation of "flat" images.  An example of this is we have some artists who purchase products, poses, characters, etc and render them into comics that they can then resell here, or anywhere else they choose.  They own the rights to their comics even though they used a product to create them.  However, if you intend to use them in a game, it gets complicated. If it's an interactive asset, then it would require the "Extended" license version of the product to be purchased. These licenses are specific to the product, so be sure to read each license agreement before purchasing and downloading anything. As for using flat images in a game, that falls into a gray area, as you have license to create flat images for commercial use, but in a video game, if what you are using is an object like a table that can be walked around, even though it doesn't move or change shape, the game has to manipulate the camera angle and then the raw 3D asset needs to be in the game which can be ripped...which is why the extended license is required. Creating an image to use in the game like a magazine cover or a picture on a wall would be okay as the image is flattened.  In the end, you're always best to overprotect yourself with copyright licensing and not leave yourself open to legal liability. Hope this helps.
