Hi N8128, Thank you for taking the time to point out this information to me. Our lead programmer has been tracing down the issue and it seems on point with exactly what your saying. And yes at the moment I’ve been following the pointed out method on how to setup the wavesworks quadtree setup as all others have been doing as in the attached image. I figured that this was the way to do it, now on a weird note if you go back to the UnrealEngine-4.9.2_NVIDIA_Techs build from the cook process works perfectly and there are no issues, but in the 4.12.5 build intergration this is where we start to run into the problem. Again thanks for the info, going to see what we can figure out with this. Its a great start and lead to try to figure out this problem.
