Tmi to Fbx file conversion

Hello, I have some TMI plant files I have purchased and my computer is struggling to run them due to the size of the site / volume of the models. Looking to export them from Twinmotion as FBX, lower the polycount in Unreal then reimport them to Twinmotion. So far I’ve gotten stuck at the exporting stage and am getting this error


I am fairly confident with Twinmotion but a complete beginner with Unreal. Any advice would be helpful, thanks in advance

Hi there @nasan_ofpersia

Welcome to the Unreal Forum! Did you create a project in UE? (It’ll have its own folder, config, etc) If not ensure that you setup an UE project(Or set a new one up if you don’t). You should be able to open Twinmotion, go to the export settings and set the root folder of your UE project. (This’ll be the main folder where your .uproject file was generated)

Try that and see if the error goes away.
