I was trying to make eyes watching this tutorial https://www.youtube.com/watch?v=gfEyhPXsOCM but but when I exported the eyes to Unity as glTF the eyes didn't have any textures to it it was just plain white how do you export all the nodes to Unity at once?

glTF 2.0 has a specific PBR material model, for transfer to realtime rendering engines. It cannot support arbitrary arrangements of Blender nodes, as for example a mobile phone wouldn't be able to handle realtime rendering of complex Blender nodes. Instead, the glTF material definition has a strict number of fields, corresponding to a particular interpretation of physically-based materials.

The Blender Manual documents how to export materials to glTF.
