Hi, I imported Open World Demo Collection into my project. When i try to open or drag to foliage or scene any asset Unreal freezes. CPU, GPU and RAM usage is stable. Sometimes Disk usage increasing. What can i do now? It’s same with another pack.
My Pc
AMD A10-7870k
Nvidia 1050 Ti
MSI A68HM-E33
HyperX 8GB
it depends on the size of the assets, if its too large, u must wait, otherwise import them piece by piece, or u can open the content folder and just copy ur fbx files and textures , then open the engine .
Nothing changed. 
one more thing, just import one FBX file , a simple one.
then when u try to select the engine window , it will not respond, right?
Then , Alt+Tab to access it, bec the pop up window for imported asset make the engine main window un selectable for some reason. at least for me, try this out and let me know
The first time you open a new asset in a project the engine needs to process it, generate mip maps, etc, which can take some time. After the assets are processed for the first time, you will no longer have a delay when placing assets.
Opening a texture of say 4096x4096 and ~10mb in size for the first time can take anywhere from 5-20 seconds on a fairly powerful PC. The Open World Demo collection’s textures however are absolutely massive, some textures are 350mb or more in size, and some of the materials use multiple textures that size, plus the meshes need to be processed, so it is going to take a really long time to load in the first time if you are dragging it into your scene.
To pre-load in the assets one by one, go into the content browser and double click each texture and mesh one by one (materials will be fine, it’s the textures that need to be loaded) and wait for it to load, then close the asset window when it has loaded and move on to the next one. Unfortunately there isn’t currently a faster way to do this, but it is only a one time thing thankfully.
Hope that helps!
Yes, that works. thank you for help
