well this time there is a shader so...
i need to teach u how works
When u put textures into the shader u have to use the original material from the shaders file (if is the comic shader: Comic Style Shader or the sketch shader with the material: Sketch Style Shader )
Put the textures in that material and put the material in the model that u want
if u dont do this and u use another material the shader can be fully black or u will cant use some values so u have to follow the instructions :D
if ure shader get fully black u can select the node and press the TAB on ur keyboard and search the outline box, there u can fix that moving the color ramp (i'll let a image of that box here)
(please follow the instructions for avoid errors)
and that is it :D
works on Blender 3.5
