hello I wanted to know if it is possible to create your own buildings / houses / stations / and others in the editor? this is possible in the editor, could you tell me or send me a video link to know how to do it !
You need to do it in blender, the editor doesn't directly support 3D modelling your own assets. There are tons of tutorials on how to make something in blender and import it in Unreal Editor. The same steps apply for TSW Editor in general
Be sure to use blosm plugin if you need a template for real buildings =) Blosm is a googlemaps 3d building importer.
