I'm a huge proponent of buying models from third-party online marketplaces. As a consumer who has purchased a lot of this stuff, and built an entire RPG out of assets like this, here are some things I look for when buying that might help you when creating:
Generally when determining my needs, I first look at if I need a static or skeletal mesh. If I only need a static mesh, my "requirements" are much lower. For example:
Static Mesh can be in FBX, OBJ, or a native format for a software package I use (like Maya, Blender, UE4, Unity, whatever). I care way more about FBX, so I generally will only buy models that are in FBX format, and only use another file format if there is no other option and I absolutely must have the model in question (but this is very rare).
Static Meshes, like Skeletal Meshes must have textures, and be properly UV'd. Bonus points if the textures are easy to modify. https://scrabblewordfinder.vip/ https://www.applock.ooo/ https://www.7zip.vip/
