    Default Minotaur - rendering and modeling (tutorial available)

    ZBC1.jpg
    Some of you guys asked me how I’ve texturized and modeled the “Minotaur” character; just now I managed to finish a short tutorial I’ve promised I’ll make.
    I’ll begin with the texturing and rendering , because the most of you were interested specially on these issues and then, I’ll continue with modeling.
    Regarding the texturing part, first, I’ll show you how I’ve obtained the old painting effect. In order to achieve this effect, first you have to open a model and to apply a basic material on it. Then, you have to make the following settings:

    01.jpg

    Using these settings you’ll get a basic worn paint effect, but you can make many changes and transform it depending on your needs. Using a few simple settings for the slots I’ve indicated in the schetch, you can control the expanding rate of the painting, the details, specular, bump, etc.
    The image I’ve obtained is this:

    02.jpg

    The next step was to render the following images, images that I attended to be composed in Photoshop later(including red pass).

    03.jpg

    In Photoshop, I combined red pass with green pass (whith masks) and I obtained color-mix1.

    04.jpg

    Then, I combined color-mix1 with gold pass, using for gold pass DARKEN blend mode; the result was color-mix2.

    Next, I combined color-mix2 with specular pass and rim light, and I mixed these two as you can see in the following image:

    07.jpg

    08.jpg

    The result is this:

    09.jpg

    The next thing I’ve done was to change the background. For this, I used a mask that I created in zbrush, filling the model with a flat material and changing the background color into black.

    Then, I found an appropriate texture, I’ve added a blur and I used levels. After I finished the background, I’ve added a slightly depth of field effect to the character in photoshop (with lens blur filter), using an alpha channel I’ve created also in zbrush. The last details I’ve added were the graffiti drawings and the inscriptions, which I applied using soft light blend mode mostly.

    11.jpg

    Finally, I made some general adjustments, I added a sharpent filter and I used levels. This is all!


    Regarding the modeling part, first, I had to choose a right mesh for this character or to create one from scratch, using zspheres, but finnaly I found a suitable one on the download center. I modified it a little and I used it. Regarding the concept art part, it was made directly in zbrush, without intermediary schetches. I think it’s more difficult to work in this way, but I think that it can be obtained more original and spectacular results because you are not focused on a sketch but forced to search shapes and concepts free, and the result can’t be other than a spontaneous and a fresh one. The previous phases of the modeling are not strict from the technical point of view, but even negligent, but this way of work has as a purpose the shapes defining and the building of a concept. When I find a good idea or interesting sculptural shapes I become very strict with the technical part and I begin to outline the concept that rise.

    12.jpg

    After I outline the general shapes and after I define a future concept, I go to the next step when I clean all the imperfections of the modeling, and I create very precise shapes technically speaking. After I finish this step I go to the next one, the final one, when I add sculptural details using alpha. These are a few of alpha I used for this character:

    13.jpg

    Regarding the brushes I used for modeling, the most useful ones were: clay brush, hpolish, movetool, Smoot, Smoot Stronger, dam standard, standard brush, but the most used one was a version of the clay tubes, without alpha, with a focal shift of -60; I used this brush in about 70% of my modeling, it is an excellent brush not only for the hard surface, but for an organic modeling of surfaces also – I use this on every project of mine.


    14.jpg

    Using this type of brush I created the “Minotaur” and organic characters like this one.

    15.jpg

    Even the model looks fragmented and seems to have many subtools, it has only a few ones. The reason for not using many subtools was that this character was created like a modeling experiment and I was interested more to sculpt it using a singular shape, like the traditional style of clay sculpting; I wasn’t interested to split it in more parts. I worked many years as a traditional sculptor and I worked with many materials such as clay, stone, metal, wood, and it’s surprising how much the zbush modeling is resembling with the traditional way of clay sculpting.


    16.jpg

    From the moment I started the base mesh modeling and till I get to phase 3 of work (see the picture whit 6 modeling stages) the polygons begun to stretch because the fact that, compared with the original mesh, the model sizes grow and that’s why, from the step 4 I used the option project all, option that allowed me to create a new dense mesh, that copied all the details of the previous model . After this phase I could add the final details on a dense mesh of 15 millions of polygons.

    The work phases regarding the modeling of this character can be resumed in 3 steps:

    1.sketching the general shapes without entering too much into details , establishing the composition and the overall concept;

    2. cleaning up the shapes from the technical modeling imperfections, adjusting the lines and the shapes;

    3. adding the sculptural details with alpha.



    These are a few images of tests I’ve made with this old painting effect, I hope you’ll like it; it wasn’t meant to be final renderings, but only some material tests.

    In these two images I tried to get an old bronze effect.

    These next three renderings are from Zbrush without photoshop. (except the background of second image, and minor level adjustments) I use a double shader material and I tried to create a nice metallic material.

    This image is similar to previous but it also added a gold pass in photoshop.

    I hope this information was useful, thank you for reading!

    Thanks for the detailed tutorial and settings. Amazing design and process. So The metal coil wires effect around his upper chest is a combo of Clay Tubes + alphas? Amazing.

    Especially impressive considering no retopology was necessary. Now let's see a 3D Print.

    Congrats on the top row.

    Thank you for sharing, loved the materials, always wondered why they make rimlight, and alpha masks, now it's clear...Thank you for including the Photoshop layer images, again it clarifies your process and of course the modeling steps are great...

    Could you shed some light on how you do repetitive details such as the bullets ont he band coming over the shoulder...Thanks again..Danny
