Having error like this "Room object has wrapping UV's


I am a beginner in Unreal engine. I started using this engine from last one week, before that i was using the unity3d.
When i started using unreal i faced lots of doubts in this.i mentioned one of the issue here. I imported my 3d room into the unreal i just cliked the import button and selected my room obj file and imported. After that i set the lights and i built it when the build going to finish its showed the error message like “room object has wrapping UV’s”.
After that my my whole scene get green color. i set all values in editing panel i changed the uvchannel to 1 and baked. Eventhough its not working. i have attached my screen shot here please check.
