Re: import 3d model to unreal engine If you exported multiple levels, first try it with a single level. By-the-way, doors and windows are also 'furniture'. Actually, everything is just an object, a mesh described in the OBJ file. So maybe start with only walls, then add furniture as long as everything keeps working. You might also try with a single door and then with two doors. Maybe double objects cause a problem. (If you can't find the source of a problem you try everything, no matter how weird it may sound :) ) I assume that you export as a single object because with multiple objects UE gets a problem with already existing asset names. A single object should be seen as a single asset so make sure the name is unique in the UE asset list. ETA: just thought of something else. Import the object in Blender and export it again. Blender and Sweet Home 3D produce different formats of the same mesh so it might make a difference. If that doesn't help try a second method: add a line in the OBJ file before the first "g " line with "o my_object_name" (an o, not a zero, without the quotes). Then import in Blender with the setting import objects on, groups off. Export from Blender and try again. This will merge all groups into a single object. Importing the materials from MTL seems to be a problem more people encountered. Look it up in the UE forum. ---------------------------------------- Dodecagon.nl 1300+ 3D models, manuals, and projects |
