Once you know where you are going you can start to model the low-resversion of the different pieces of your scene.IMPORTANT: you need to unwrap the UVs of all your models(I used unfold3D to do it quickly)All your models have to be in quads, if not you will experiment problemswhen you will start to model in Zbrush.



Before importing your model in Zbrush you need to prepare your work space. I have a multiprocessor in my computer so I activate the MULTIDRAW and THE MULTIRENDER. To see if it's worth it on yours launch the TEST MULTITHREADING. Then I go to STROKE and put 4 in MOUSE AVG (you will avoid some shaking effects of your pen)



Now I can import my model and start working. Personally I like to work with the INFLAT tool and smoothed curve.

For the details I use the projection master with the directional brush and some brush I made form heads pictures. Don’t forget to remove MRGB and to activate ZADD or ZSUB.




Now I have all my pieces ready in Zbrush


Now I want to export my models to 3dsmax. First I go to lower division (1 or 2) in Zbrush and I activate the CAGE button (the low res mesh tries to match with the highest division) Then to create my displacement map I use the MULTIDISPLACEMENT 2 pluggin with these options:

There are tons of good texturing/shading tutorials so I will not cover this part. (For this one I used a lot of camera mapping/render to texture) It's a big piece so I will try to make another tutorial on that next time.

3Dtutorials.sk recommendation:
To maximise the realism of your character we recommend to use high quality face photo textures from the #1 texture website www.3D.sk

I have all my models in 3dsmax textured and with displacement modifier, I can start the lighting.


For this scene I used 4 lights. A sky light (intensity 0.3) for the ambient, a directional light that will affect just the diffuse, another one just for the specular, and what I will call "red light" for the back light. This way I can move my "spec" light to have exactly what I want.

When I have all my lights I do a grey render to check if it's what I had in mind.


I'm not really sure about the back light intensity and I don't want to spend too much time adjusting the light. So I turn it's color to RED, turn off the other lights and do a render. I will use this render later on Photoshop by selecting only the red channel, copying it on a new layer and turning it to white. I will be able to play with the light intensity directly in Photoshop instead of 3dsmax.


I do my render with the textures activated and the RED light off. At this point I don't care about the colors and the contrast because I plan to tweak everything in Photoshop.


Before I go to Photoshop I need an occlusion render. There are different ways to do it and for this one I used only a sky light (intensity 1) and a white material on all my models. I will use this render in multiply mode in Photoshop to accentuate my shadows.

Ok, now I have everything I need, I can close 3dsmax and go to Photoshop. First I take my basic render and add the occlusion pass


To have more consistency between the colors I add a color layer in soft light mode


The red bandana alone is a bit disturbing so I have to find a background picture with some red color to do a recall. I did a montage with 3 different pictures; I blurred them, added some noise and played with the colors to get what I wanted.


Now that I have the right colors and the background I can use the RED render for the backlight. On this one I used it twice. One in normal mode and a blurred copy in screen mode.

Rock 'n' Roll" by Rodrigue Pralier


I don't really like clean renders and prefer when you can feel it was handmade. To have this effect I add dirt, textures and various things.

play again with the levels, the curves etc. in order to have more color contrast
