Game Development Reference
Select the texture and switch back to your material editor. What we want to do is
create a node represening the texture. In the Material Expressions list on the right,
scroll down unil you see Texture Sample . Select it, then click-drag it into the gray
viewport to the left, and a Texture Sample node should appear. If the node turns out
black, you may not have had the texture selected in the generic browser. Delete it
and try again.
