Wario has bone sliders to manipulate the tone of the color, the saturation, the brightness and the gamma (i call it the light contrast as it slightly burns the material)

As i move the sliders to modify the values the texture is modified, achieving that deluxe effect with of course the final compositing i will show in the future

Wario has many materials to separate all the elements (shirt, arm skin, shoes, teeth upper and lower as separate values, moustache, eyebrows, eyes, eye cornes or that blue part of the eye, and also the hat that has the letter, the white part around it and the front part of the hat all separate from eachother). This is done to get the bright spots and dark spots in the render.

This is an example of the bright and dark spots. The bright spots are on the left and the dark spots are on the right. The characters will be separate renders from the rooms because i will mimic the lights and shadow projected on the characters with point lights to achieve the Deluxe effects

This is how i make and will make the characters from now on to get the desired effect i wanted to get a while ago. And i will apply this method on Waluigi, Peach and Mario too
