Hi Elliott, This is a great breakdown and very generous in sharing your process and insights, you came a long way from the vending machine days!
Are you planning on releasing the UE4 project to the public? Or only builds? I'd love to play around with it in the editor if possible!
Team Sketchfab unveiled two new features at SIGGRAPH this year that will be available to the community members very soon. First of all, the company announced support for subsurface scattering, sometimes known as SSS. The feature simulates the effect of light as it enters semi porous materials like skin, ceramics, wax, or milk, as light enters the surface of the material, and is scattered. The team has also improved material, texture, and topology workflows with the new Scene Inspector.
Here is an overview from the specialists:
The effect is often subtle but critical to giving a more realistic appearance. Here’s an example in action:
Use ALT/OPTION plus your mouse to change the rotation of the environment to better see the effect on skin as light conditions change. On mobile devices, drag with three finger touch.
We’ll have more detailed information to share soon, but you can see from the panels on the left-hand side of this view of our online editor that we have a very comprehensive SSS solution allowing you maximum flexibility with your work:
We’ve also significantly upgraded the ability to share and understand the material, texture, and topology make up of Sketchfab scenes with our new Scene Inspector.
The Scene Inspector, accessible through the Sketchfab player’s UI wherever it is embedded will allow you to more closely examine aspects of a scene, including a breakdown of all PBR textures, normal maps, ambient occlusion, cavity maps and many more. Wireframe topology views, a UV checker view to visualize UV stretching and even 2D views of the textures and topology used in your scene round out a comprehensive new tool.
The Scene Inspector is a great way to show off the quality of your workflow or to learn more about how other creators have approached their work.
Stay tuned for release dates and more details on the upcoming features.
