When I try to build the light, it freezes for some minutes, then it get 100% exported scene and will not do anything after that. Is this a bug? And is it a way to skip the Exporting Scene so the light can be build or can you set an auto light building in unreal? I use a Windows 10 pro 64 bit Geforce gtx 1080 Intel(R) Core™i7-7820HK CPU @ 2.90GHz 32BG ram ![256584-hhh.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/7/8/b/78b4650e6a1b0352d791bc90f822c982e098e077.png) ---
