In Art Spotlight, we invite Sketchfab artists to talk about one of their designs.
Hello! My name is Adam Beamish and I am currently working in England as a graphic artist for Autodesk. You can usually find me moderating the 123D Sculpt+ community where you can see some of my latest work. I have been using Lightwave 3D, Mudbox and Zbrush for a few years now but I was drawn to the portability of 123D Sculpt+ on the iPad as I don’t have to be tied down to a desk. For my personal work I use 123D Sculpt+ as my main tool for starting a sculpting project and then using Zbrush or Mudbox for finishing off.
If you haven’t seen Autodesk’s 123D Sculpt+ app it is a sculpting application for the iPad, Android and Windows tablets. It is basically an introduction program to sculpting. 123D Sculpt+ may be limited and simple but it’s ease of use makes it quick and easy to learn. It’s no Mudbox or Zbrush replacement but is very handy as a mobile sculpting companion.
The idea for the zombie bust came about because at the time it was Halloween and zombies were popular in the media. I wanted to see what I could accomplish in 123D Creature/123D Sculpt+ (123D Creature was the previous name of 123D Sculpt+) without using Mudbox or Zbrush.
First of all I wanted to see what I could sculpt from just a sphere. As 123D Sculpt+ has a polygon limit you are restricted to how much detail you can add so every polygon is valuable. First in the model skeleton section I created a sphere model. A sphere can be made using the skeleton sections or by selecting one of the model presets. Next onto the sculpting, but first you need to press the bake button to transform the skeleton model into an editable model to sculpt on.
I used the grab brush to pull the sphere into a head, neck and shoulders shape. From here I start to block out the basic shape forms of the face with the sculpt out brush.
Once I was happy with the basic shape I then started to add in the basic facial features. Knowing there is no subdivision and a limit to the amount of polygons I made the best of what was available.
With the basic features blocked in I started to add more detail and refine the overall shape. The limitations of the brush size stopped me from getting the best detail out of the model, but with a little bit of pushing and pulling with the grab tool I was able to move surrounding polygons to nearby areas where extra polygons were needed. Getting to know the sculpting tools first helps to learn their strengths and limitations.
In the painting section of 123D Sculpt+ I gave the model a basic mid tone colour. From here I added dark shading into the crevices and added highlights to help accentuate the sculpted forms.
Once I was happy with the main colour I started to add a skin texture all over using an alpha map in the image rub section. As 123D Sculpt+ only has a colour image map I try to add as much detail into the texture as I can. Alpha map textures in the image rub section is a great way for adding additional detail quickly. The rest of the model was finished by painting in wrinkles and extra details into the eyes.
The model is now basically complete and ready for light setup and final image output. In Sculpt+ you have a few limited light preset settings which you can adjust in the environment settings.
Within 123D Sculpt+ you have the ability to export the model for 3D printing. It was the following year that the zombie model was printed for the Autodesk stand at the 2014 Paris 3D Print Show as a full colour print.
To get the model working properly in Sketchfab I exported the model from 123D Sculpt+ into Zbrush to clean the UV mapping as models from 123D Sculpt+ can create white UV lines which can be visible in other software programs. Then I exported the model as an obj file with the image file and zipped the project up and dropped it onto the Sketchfab website for editing.
When I discovered Sketchfab I was impressed by the realtime rendered look of the models in the community. I decided to try out my models from 123D Sculpt+ and I was pleasantly surprised by the results I got. I will definitely be using Sketchfab again and making better use of the texture options in the future!
