Drone Mapped Track

[MXDAD#HS46]

Hi all,

I've recently used TFC's track tutorial videos to build our local MX track.  The videos were a massive help (thanks TFC) and the track came out pretty decent in the end, of course, it could be improved. 

So, I've used my drone to do a 3d map/model of the track.  I've rendered the track using WebODM and it looks MEGA!!  The heightmap looks 100% accurate and the texture is good enough to pick out individual stones.  I've been able to move the track to another program, QGIS, but I'm struggling to recreate it with L3DT.

If anyone could offer any guidance or instruction to help get the track into MX bikes, I would be very grateful.

Thanks
