Fortnite 41.20 aggiunge rig Sidekick, voci NPC e widget UMG

Epic’s 41.20 Fortnite ecosystem update arrived on July 16, 2026, and it adds the first wave of Control Rig support for Sidekicks in UEFN, plus in-world UMG Widgets and new island content including the Bank Shot Pistol, Smoke Grenade, Friend Zone item, and Sinister Strip prefabs and galleries. The update also says creators can publish islands with Sidekicks and Creatures-themed assets starting July 23. Epic’s release notes spell out the changes.

What’s new in the update

• First wave of Sidekick Control Rigs in UEFN
• In-world UMG Widgets for island interfaces
• New gameplay items: Bank Shot Pistol, Smoke Grenade, Friend Zone
• Sinister Strip prefabs and galleries
• Publishing opens July 23 for Sidekick and Creatures-themed islands

Epic says the Sidekick rig support uses the same internal rig structures it uses in-game, and that creators can animate three archetypes at launch: Dog Large, Dog Small, and Cat Small. That makes the update more than a content drop; it gives island builders a new animation workflow for companion-style experiences. The official notes say the tools are live now.

Why it matters for creators

• More control over companion animations
• New UI options for diegetic interfaces
• Fresh themed assets for creature-focused islands
• A near-term publishing window to plan around

For IslandAtlas readers, the key takeaway is timing: July 23 is the next publishing checkpoint for this feature set, so creator teams can already build toward it rather than waiting for a later rollout. Epic’s docs also indicate the update is live on July 16, making this a real mid-summer ecosystem shift rather than a teaser. Epic documentation confirms both dates.
