Transfer a Twinmotion file into UE 5.1. 5.2 using the new Datasmith Twinmotion Content plugin. 

This is only way to transfer Twinmotion to Unreal if you use UE5.2 or later. Please notice this process should work the same as future UE engines. You just need to make sure you create a new project using the “Architecture” template. 

step 1: create a new project using the Architecture template

step 2:  Activate the plugin

step 3: Add Datasmith asset

Please watch the following video for the entire process.  More detail in UE documentation. 

Step 4. Adjust the indoor lighting and material.

If it is only interior with no view to the sun, you can remove the volumetric cloud, sunsky system ( directional, skylight, sky atmosphere), fog.
