It seems this tool is working much better than UT4XConverter.Is Unreal Editor 4 supporting .t3d map files format after using UE4-T3DConverter should I copy and paste texts content as last step,right?Because in most of old maps related to(video games powered by)unreal engine 4 version preccessors 1,2,3 have lots of missing vertices.
First, make an 8000x8000x8000 additive brush in a new ue4 level before importing \ copy - paste the content of the new generated t3d file into the level.
