I did everything by the book. aka readme on github using listed unity version when opening project folder unity starts importing fine until gets to importing small assets ,memory instantly starts climbing and uses all my system 32gb memory and pagefile and then crashes with out of memory error. specs windows 10 64bit 19h build amd ryzen 1700 memory 32gb nvidia 2070 edit:update I installed windows 1809 to a clean partition in dual boot, installed unity and had it install visual studio 2015 and cleared out the library folder in the fpssample folder and open the project in unity and it still during, importing assets, memory usage went high and editor crashed. I also tried windows 10 and unity in vmware and it opened the project with no problem and then I copied the project over to the normal windows 10 install and unity opened the project, but started getting errors with pipline in LightLoop build and garbage collection and memory usage went high and editor crashed edit: i been working with this for 3 day, different unity versions. and they all crash on importing assets from memory leak.I tried it on clean install of windows 10 preview insider build and windows 1809 build and clean installs of unity3d. I was looking forward to learning and working with this project but I cant even get it to open.... edit: wow holy crackers, I got it to work. but I had reclone the project and open unity3d in vmware and when the editor was done importing and opening the project, I copied the project into windows host and then run unity3d and it opened the project and everything is working now.
