When launching and using Twinmotion 2025.2 or 2026.1 offline, the Megascans library becomes unusable due to the subfolders of the 3D assets, 3D plants, Surfaces and Decals folders failing to display. This prevents users from accessing any previously downloaded content stored on their machines while running Twinmotion offline.
This behavior is new to Twinmotion 2025.2. In Twinmotion 2025.1.1, all Megascans subfolders properly displayed when offline and any downloaded assets could be accessed and used.
Result: You will be unable to access the downloaded assets while disconnected from the internet. None of the subfolders for the 3D assets, 3D plants, Surfaces and Decals folders will populate. The assets can only be accessed after reconnecting to the internet and relaunching Twinmotion.
