Behind the Scenes: Anatomy Model 2019

About Me

Hello, my name is Dawid Krzyżanowski. I live in Poland in a small picturesque town in the south of the country. For the last 2 years I have been working in a small studio doing games as a 2D / 3D artist. This year I decided to return to work as a freelancer.

Since I can remember, I have always drawn, and in the end this hobby became my day job. I have dealt with 3D graphics for almost 4 years. Before I was mainly doing 2D art. Today I also draw / paint, but I spend most of my time on 3D. In my work, I try to combine my skills in both these areas.

I am particularly passionate about the human body and anatomy, which is why today I want to share with you the process of creating my last model.

My hardware (ASUS ROG laptop):

-Intel core i7 7700HQ
-16GB RAM
-Geoforce GTX 1060

Software:

-Blender 3D
-Krita
-Substance Painter
-ZBrush
-Windows 10
-PureRef

My workflow

In every project it is always important to determine the main goal that you want to achieve at the end. This allows you to stay motivated, especially if you are dealing with such a broad topic as human anatomy.

In this case, I wanted to create an anatomical model that would be realistic but at the same time would facilitate the recognition of individual muscles. This procedure required simplification of some elements. I also wanted the model to be reliably low poly and PBR

I started the project by gathering references and refreshing my knowledge of the human body. If you are just starting your adventure with anatomy and approaching it seriously, it is worth learning the correct muscle names, how they work and where exactly they are attached. Although for some it may be too hard to watch, it is best to find on YouTube videos from the real sections of human corpses. Videos from the "Acland's DVD of Human Anatomy" series are particularly good. It is also worth using 3D models available on the web, and books for anatomy. If you use Pinterest, I invite you to follow my anatomy board.

About this model

I started the process of creating by quickly blocking the whole body from simple cubes. My goal was to have good proportions from the beginning.

I used the whole modeling process in two ways. For more complicated elements such as the skull, I first sculpted the main forms in Blender and did retopology, and then added smaller details in ZBrush. However, the simpler ones I started from the low poly modeling and then I sculpted and added details. I baked all my maps in Substance Painter.

Texturing was done partly in Substance Painter and partly in Blender (mainly the albedo map). Substance Painter is great when it comes to procedural texturing and the ability to paint on several channels at the same time, while Blender is great because, for example, it allows you to hide individual elements of the model. First I exported my low poly mesh and my high poly mesh to Substance and baked normal map. I use the "by mesh name" setting to bake because I don't want any artifacts in the normal map caused by overlapping geometry. I export this map to png, and set up materials in Blender. In Blender I paint my albedo map using simple paint mode. I look at many references when doing this step. I finally export the finished map to Substance Painter and create procedural details using some simple generators like dirt. When I am happy with the results, I export all the maps back to Blender and set up lighting.

The last step was to set the materials and lighting. It must be remembered that even material such as bone partially transmits light, so you have to set properly the SSS. However, do not overdo it so that the whole thing does not look like wax.

At lighting stage, I did not limit myself to the standard 3-point lighting. It is important that the model looks the way we want it to.

A few final shots from the Blender 2.80 viewport:

Finally, a few tips

  • Give yourself time. Learning anatomy is a long process
  • Knowledge of correct naming makes learning easier
  • Having a clearly defined goal gives you a lot of motivation
  • Use as many sources as possible to learn

That's it from my side. If you are interested in purchasing this model, you can find it here.

If you do not want to spend money. I also have a free model that can help you learn anatomy.

Never stop learning. Good luck;)

      Hi, I am Dr Bishwajeet from India, I am a general physician with MD Anatomy and would be very interested in working with you in creating 3D graphics for human embryology. I have been thinking of doing it for quite very long, as I am knowing and teaching it to medical students, I can provide sufficient inputs for you so that we can develop it in near future. Will be waiting for your mail. Inbox me at [email protected].. thanks.
