Hi Elliott, This is a great breakdown and very generous in sharing your process and insights, you came a long way from the vending machine days!
Are you planning on releasing the UE4 project to the public? Or only builds? I'd love to play around with it in the editor if possible!
Renderpeople has recently released a ready-to-use animated 3D People freebie called Sophia which can be used commercially and downloaded without registration. Let’s take a look at the model.
Renderpeople is a studio that provides lifelike and easy-to-use 3D People for different renders. The project offers a range of free products, as well as some paid ones for you to make your works stand out.
Finally, here they are… the newest addition to our 3D People line-up: the Animated People! Just import them into your 3D scene and you are good to go. Available as 3ds Max, Cinema 4D, Maya, and FBX.
You can learn more about the project and get the latest free model here.
