Per Hitech's instructions I uploaded my gunnery terrain to the HOST today.
DX11 game client.
1. - I can run build with no errors.
2. - I can run error checking and it passes for HOST upload.
3. - I can run the uploader and the terrain is processed and shows in the list for Player terrains when I click "create".
4. - I did not know about the new patch 3.00 patch1, after it auto installed I reran build, error check, and uploaded successfully.
I tested a create of the Trainers terrain with only defaults and it ran successfully. When I choose the gunnery terrain and leave everything at the defaults, it begins to initialize, then after 60 seconds "Host Lost" and my game hangs. I made three attempts with the same results.
