What is UV unwrapping and do I need it?

UV unwrapping is the process of flattening a 3D model's surface into a 2D image. Yes, your model needs to be UV unwrapped for TextureFast™ to generate textures. Most 3D modeling software (Blender, Maya, 3ds Max) has built-in UV unwrapping tools. If your model doesn't have UVs, the texture generation will fail.
