AI Character Generator

The AI Character Generator tool enables you to create random characters with specific characteristics and facial traits. Similar to the Photo-to-3D Character generation tool, if produces animation-ready 3D digital characters in the user template style, from a set of user-input descriptors: demographic descriptors (gender, age, ethnicity, skin tone) as well as facial shape descriptors (nose length, eye distance, mouth width, lip height, etc.).

AI character generation makes it easy to populate games with unique characters, while ensuring consistency with the game art style and technical specifications (mesh topology, animation rig).

Use in Popul8

Create an AI character generator from any existing character Template by right-clicking on the template and selecting Create > AI Character Geneator .

In the configuration settings, select the desired gender, age, ethnicity and skin tone via the drop-down menus.

Additional statistical constraints can be set by modifying the low and high values assigned to the respective facial shape descriptors (nose length, eye distance, mouth width, lip height, etc.). These values represent the low and high quantiles, respectively, of the distribution to be sampled from. For instance, set the low value of the head width to 0.95 and keep the high value at 1 to constrain the generated character to have a head with larger than 95% of a normal population.

Finally, name the character to be created, and click Apply Changes.
