I did plan it initially but this course hasn’t been very popular so the texturing course dropped off the priority list. Most of the information needed to texture a robot character like this can be found in this course. Only caveat is that course teaches Blender + Substance.
That said I would still like to revisit this project to teach the texturing portion. If I continue to get questions like yours I will try to make it happen (and all in Blender)!
PS: Since this course wasn’t so popular, I’m curious to hear what you think of it when you finish.
