Is The Tsw5 Editor Still Using .asc Format

I've worked through QGis to convert my dem data to .asc format but when i import it the editor doesn't see the files as a supported format has something changed since last time i used the editor when it was tsw4

 

no it uses fbx, which then gets convered to an unreal asset when you import it into the editor

 

ahh thought i'd sorted it out i inserted the asc files , use selected assets wasn't working so i added each asset manually 1 by one and then right clicked LandscapeStreamingProxy and then apply lidar data to selected proxys and its sorted it out. never knew anything about .fbx file format so am i needing to delete what i've done and get .fbx files inserted?

 

Oh sorry thats my fault i thought you were talking about model assets not landscape assets
