Hi, say i have a jpg of an eyeball, in the material room, what node do i attatch the jpg to?? I know i have to create a new node and 2d and the image, and select my jpg. But what dial do i connect it to?? Any info is appreciated!! Thanks Tim

Create the 2D image node, load the JPEG into it, and attach it to the Diffuse_Color channel. Repeat as necessary for other eye materials (iris, pupil, eyewhite, etc.).

Or you could attach it to Alternate_Diffuse, instead, depending upon the effect you're trying to achive.
