IMPORTANCE OF UVS
Although having uvs is not a requirement for this tutorial, it definitely helps to improve the look of your model – especially when using surface noise and while adding the different textures in Keyshot. You won’t have to tweak the parameters of the bump and the specular as much. if this is the case and you have the uvs, go to the Texture Map node and view the Mapping Type. For models, the Without uvs box usually works fine but in case your mesh has them, change it to uv.
