Arnold Schwarzanegger likeness
A personal project of one of the most iconic action actors of the 80's and 90's. Modelled in zBrush, textured in Substance Painter. Lookdev and grooming done in Houdini with Arnold render.
Modeling
-
zBrush modeling
It is important to pay a lot of attention to the low and medium frequency shapes which is really where you get the best resemblance to the reference model.

Hand made high freq detail modeling
Although it is common to project textures (like texturesxyz) on the models to achieve perfectly realistic high frequency detail, in this case all the detail is hand sculpted using different alphas and paying attention to the size and directionality of pores and wrinkles, each area of the face has its own high frequency detail. From this detail will come the displacement map.
" I'll be back. "
My little brother Henan Expósito has made me in blender this Persol 58230 replica of the glasses that the T800 wore in the movie Terminator 2: Judgement Day.
Grooming in Houdini
-
Master Guides
5 separate channels have been created for each hair type: eyelashes, eyebrows, peachfuzz, bear, headhair (you can see different colours in nodegraph). In this template I have created, you can use a hybrid system of procedural and manually assisted guide creation in the areas where you need to control more detail.

Custom Hairgenerator HDA
In order to make the task of hair generation easier, I have created a custom HDA that allows me to control the amount of clumps and subclumps as well as a whole series of noise and shape modifiers to give a better look to the hair fibres. It has also been possible to add the headband as a guide and fibre collider to avoid unwanted intersections. Undoubtedly one of the most complex parts of the whole project.
Lookdev with Solaris

Lookdev Solaris template
In this image you can see the structure proposed to develop the lookdev process in Solaris. Two routes can be seen, the one on the left where all the solid surfaces are worked on and the right one where only the character's hair is worked on. In the end both end up in a custom HDA to carry out the lookdev process.

Custom Lookdev HDA
I also wanted to make it compatible with different render engines, Renderman, Arnold, Redshift and Karma. It is possible to take advantage of Hydra and the automatic replacement of materials when changing render engines. The whole lighting and camera system is controlled from this HDA.
