To help beginner artists sketch portraits in the best way, 2 artists Şefki Ibrahim and Adam Spring shared in The Gnomon Workshop 5 steps for 3D Artist to create the most complete 3D portrait.
According to 2 artists, these are the most basic steps to get a standard 3D portrait.
Let’s explore these 5 divine steps with 3S Cloud Render Farm.
The first step of 5 steps for 3D Artist: Create the foundations
Both artists think that collecting all the face angles of the character is extremely important and necessary. Note that thBoth artists think that collecting all the face angles of the character is one of the most extremely important and necessary steps for 3D Artist. Note that these photos should be taken in the same session to have enough different angles. This will make the sketch more detailed and accurate.
Adam Spring elaborates on these angles: front, side and 3/4 are the most important. Also, other angles that can help more like a low angle, looking up, will help you see the shape of the nostrils, the width of the bridge of the nose, and the protrusion of the upper jaw. Besides, knowing the anatomy of the facial muscles will also make it easier to create different facial expressions when sketching 3D portraits.
Şefki Ibrahim advises new artists to use the base mesh when starting on a portrait. After that, the model is then imported into ZBrush then start working on the sculpt
If you are just starting out, try to keep things loose and avoid getting caught up with long projects. Adam Spring said don’t worry if your work doesn’t look great straight away. Most of his projects only come together right at the end. That why you can’t skip any steps for 3D artist that they noted.
Step 2: Sculpt the forms
The first stages are often the easiest, most comfortable, but also the most important. Both Adam Spring and Şefki Ibrahim say that correctly defining the overall framework is most important. Then comes the work of identifying details.
Şefki Ibrahim like to use ZBrush’s ClayBuildup brush. He also thinks it’s a good idea to practice sculpting on early scans to build better knowledge.
Adam Spring talks more about the steps he uses to build the 3D model. In his experience, make the frame asymmetrical. This applies to both head and full body modeling. In terms of camera placement, Adam Spring offers a focal length of 100-200mm for close-ups and 50-85mm for portraits.
Step 3: Texture your character
To facilitate this, Adam Spring and Şefki Ibrahim suggest using diffuse map scan data or data on available resource sites. However, to personalize the characters, these two artists will both edit the drawings by hand. Şefki Ibrahim put them into Maya and Arnold and did a lot of rendering tests until the right feel was achieved.
Step 4: Set up the lighting
Lighting is one of the most important steps. It make a portrait comes to life. Each different light angle will show a different mood and attitude of the character. If done well, you can sell this model to earn income.
Step 5: The last 5% of steps for 3D Artist
The elusive 5% – Şefki Ibrahim said. Ask yourself what do you want to communicate through the model. Try all the lighting angles, image focal lengths, and details to get the best shapes that fully convey your desires. Şefki Ibrahim likes to ask himself these questions when completing a portrait; After all, artists make conscious decisions with their work. That is how, over time, we create a personal style. With Adam Spring, his FACS system now uses 51 blendshapes, 9 corrective shapes, and 18 blend textures in the color and displacement channels of the skin shader.
To bring these product models to users, after going through meticulous and detailed design steps, artists often use computers with high configurations to be able to output the desired standard product. Best. Most of the rendering on your own device will take a lot of time. That’s why 3S Cloud Render Farm – Cloud Render Farm is chosen by many artists to use.
3S Cloud Render Farm – Render Farm supports fast, stable, and achieves high artist satisfaction. Currently, 3S Cloud Render Farm is supporting most of the most used 3D software and engines in 3D graphic design.
