How to go to cycles? I have these characters but I want to go to cycles but when I do the characters goes grey and purple. (Essentially The textures get removed from the character(s). Is there a way to switch to cycles without losing the textures?

I will leave one of the characters as a example. So can I go to cycles and keep textures?

-Thanks!
there is one node in cycles that will solve most of your problems: the principled shader. it is the nearest your will come to the material system of blender render.
