Today we are replacing the 2026.1 Twinmotion build on the Epic Games Launcher with a new build that includes fixes to address some stability issues observed since the 2026.1 HF1 release on April 29th.
Fixed Bugs
TM-23712 - Fixed flickering shadows on animated characters in Lumen renders.
TM-23739 - Increased stability on graphics cards with limited VRAM (under 8 GB) by adding a VRAM-based cap to the automatic quality settings, and lowering Lumen memory usage at High and Ultra.
TM-23738 - Disabled unused features (Texture Streaming and Substrate) to further reduce GPU memory usage and improve stability.
TM-23722 - Fixed a sign-in error that occurred when signing in from within Twinmotion after launch. Failed sign-ins with cached credentials now fall back to browser authentication.
TM-23723 - Fixed exported presentations not respecting "Visible configuration" settings. Exports no longer display all configurations regardless of visibility.
TM-23724 - Fixed car parts and characters assigned to a vehicle path appearing at the scene's coordinate center instead of their correct positions.
TM-23628 - Fixed crashes on macOS 15 Sequoia affecting the in-app web pages (such as the sign-in, map, and help screens), caused by a font-rendering incompatibility in CEF (Chromium Embedded Framework).
