Transformers Optimus Prime Bumblebee Movie ver 3D model

Blender user here, this model is very nice. Since the model is not native to Blender, it came without a rig and I wasn't satisfied with the materials, so I took the liberty of completely redoing the materials, with all new UVs and crisp PBR textures, as well as a functional (but not too advanced, I'm not that good) IK rig. With this new coat of paint and a skeleton, I can definitely say that I got my money's worth. It did take a lot of effort, though. It was unfortunate that I couldn't play with it right out of the box. I wonder if there's a way that I can give the model maker my .blend file so that any Blender users who purchase this model can use my rig and retexture. Not sure if that's possible though. Once criticism I do have is that, although from a distance the model is very accurate, upon closer inspection it is *a little* sloppy, with many instances of asymmetry and misaligned doodads, though I'm not sure how much of that is a model problem seeing as Blender is not its native format. This is the only model I have purchased as of now from these people, so I am unsure if this has been fixed in newer releases. I'm sure it has. Regardless, if you're willing to put in the time, this model really shines. I hope to work with more of this studio's models in the future, because they are immaculate.
