I Wish I Learned This Sooner! – Part 2 | Unreal Fest Stockholm 2025

This session recorded at Unreal Fest Stockholm is a sequel to the hit talk from Unreal Fest Prague, packed with even more hard-earned insights and lessons learned the hard way.

In this session, Alex Coulombe of Agile Lens digs deeper into the advanced—and often unexpected—challenges that come from shipping real projects in Unreal Engine.

Part cautionary tale, part toolbox expansion, this session is for anyone who’s hit a wall at 3 AM and thought, “Why didn’t anyone warn me about this?”

From gameplay systems that seemed elegant until they collapsed under scale, to UI decisions that haunted us, and networking setups that almost worked—until they didn’t—this session covers the problems you didn’t even know to look for.

You’ll learn techniques for unpacking optimization tradeoffs, debugging tactics, performance traps, and all the quiet “gotchas” that never make it into the documentation.

Whether you’re leading a team or flying solo, expect candid stories, tested solutions, and plenty of “oh no, I’ve done that too” moments. Come for the confessions, stay for the clarity.
