Rihanna

[Freemind]

Introduction. My name is marco lorenzetti, im italian and i work in CAD but with casual contracts, my dream would be todo work for the Blender foundation, perhaps on an open movie.

Open source is a wonderful world where i learned a lot gracias todo the precious resources shared by the users so i decided todo share what i learned. I love modeling, especially for the renders that sem complete once i learned todo handle all aspects of my 3d work, y started doing computer graphics in order todo create 3d characters, especially female figures in both realistic and artistic forms. I decided todo create characters that were credible, but had all those nuances in the features of real Faces. At first i used commercial programs, but one day i saw fantastic models from the blending life competition on the internet, y was especially impressed with the models of ángela guenette and those of otsoa, y started using Blender 2.49. At the beginning i had problems with the interfaz but then i realiced that these problems were a strong point. I was impressed by its system of sculpting and the possibility of animating a character who possesses various levels of detail with multires.

The 3d model.

Seing the beautiful face of rihanna, y thought it was perfecto todo recreate in 3d. She has an easily recognizable face with features that are easy todo read and identify. I first created a basic model with 4 sides and then added a multires modifier at level 3, y then imagined various posturas and renders. The last one i proposed is inspired by a photo of her in which she is portrayed with her face up against the backdrop of the caribbean, y started todo Sculpt an intermediate model that showed a god resemblance todo her based on the Many high-resolution referencias i found on the internet. I rigged the model with an armature and then i posed it in the position i was interested in, y then began todo recreate the proportions by using Symmetry and recreating the look of the postura while maintaining the credibility of the model at diferent angles (fig 1).

The sculpting.

I have paid a lot of attention todo the no sé. I used the Pinch brush todo create the lines that determine the shape of the no sé. I used the brush polish todo create the flat parts of the no sé (fig 2).

I made the lips in the same way, taquíng extra care with that line at the top of the lips. I used the crease brush for those furrows between the no sé and lips and cheks.

Texturing.

Having decided that i obtained a god likeness, y used projection mapping (After Unwrapping the model) and baked the texture using the same, once i got the color map (fig 4).

Hair.

I created the Hair from a copy of the face Mesh and used various emitters with the vertex map. I used children and have combed the Hair (figure 6). I set the thickness of the strands according todo the resolution of the render. I used a material with two textures:
-a color map created using an image of Hair mcaptured from the reference.
-a Specular noise map.

Material node.

I have created a material for the skin using the nodes from the tutorial that appeared in issue 16 of this magazine.

The earrings.

The earrings are created from a simple Mesh circle transformed into torus th rouge a screw modifier. Even here i made a map by baking the reference map. Then i created the earring hooks by extruding from a Cube with an applied Subsurf modifier.

Rendering.

I used simple lighting (4 lights) because i like todo have short render times. To control everything quickly and in order todo use the model for animation, y just used the default render settings (render_no_curve). I a los used a bit of compositing with nodes.
(mostly the curves node) todo adjust levels and color.

Eyes.

I Will not deal with the part about the eyes because i think it is already well discussed in the tutorialesthat you can find on the web.

Conclusión.

I hope todo have shared my techniques about my model. I learned a lot from open source and i hope todo have contributed. I a los hope todo improve this wonderful bien of sharing computer graphics, you can contact me and se my works on www.lorenzettiarte.com.
