Hi -
The Chair is significantly high poly which shouldn’t be a problem for the editor and on my PC it takes about 5 to 10 mins to fully import. Since you are attempting to import it on a PC with only 8GB RAM and an Intel Integrated Graphics Card it will take an exceptionally longer time to finish importation. (The PC I am testing on is a 32GB RAM, NVidia GTX770.)
Since the engine never crashes, it is still trying to process the import and if you do not get a Windows crash that means you computer is still attempting to process the asset and it will eventually import or your PC will run out of memory and Windows will force the Engine to close (Windows Error without the Crash Reporter popping up.)
Some things you can do to help the import Process along is to pre-Triangulate your model in the modeling software. If you leave it quads only, the engine has to process the triangulation which will take some time. You can also not generate UV Lightmaps in the Editor but have them pre-made from your modeling software. Finally you can uncheck generate collision.
Ultimately I would try to use the mesh you have as a hi-poly normal generator for a much lower poly mesh.
Thank You -
