Essential talks and videos
A curated, visual library of conference talks by shipped-game developers (GDC, Substance Days, Unreal Engine, SIGGRAPH Advances) and of videos by trusted educators such as EMC3D, Beyond Extent, Class Creatives, FlippedNormals, Polygon Academy and Ben Cloward, grouped by topic, with notes on how to watch a talk actively.
In a production talk, an artist who shipped a game explains the constraints, the system they built and what they would change. This page collects the talks and videos the handbook cites most often, grouped by topic, with a short note on who is speaking and what each covers.
Two kinds of source sit side by side here. Studio talks (GDC, Substance Days, Unreal Engine livestreams, SIGGRAPH course notes) come from the people who made the game. Educator videos (EMC3D, Beyond Extent, Class Creatives, Polygon Academy, FlippedNormals, Ben Cloward and others) explain techniques, often by taking apart shipped games. Use the first for what happened in production, and the second to learn how to do it yourself. For written equivalents, see game art breakdowns: a curated library and postmortems worth reading.
#How to watch a talk actively
A one-hour talk watched passively leaves few usable notes. A few habits help you get more from it.
- Note the constraint first. Most production talks are a story about a problem: memory, team size, schedule, a camera the player controls. Write it down in one line before the speaker gets to the solution.
- Pause on every breakdown slide. Wireframes, texture sheets and kit layouts carry most of the information. Screenshot them and count pieces, strips and texture sizes, the same way you would read an art breakdown.
- Write down numbers. Texel densities, kit footprints, triangle counts and memory budgets are rare in public. Collect them, with the talk as the source.
- Separate method from taste. A studio's art direction is not a rule. Note which decisions came from the game's needs and which from style.
- Look for the speaker's other work. Many speakers also post ArtStation breakdowns or slides; the companion material often has the numbers the talk skips.
