Open World Demo Collection - Long Load Time In Editor

So I am trying to use the assets from the Open World Demo Collection in my project, but when I take an asset, say Hill}Tree_02 and drop it in the editor it takes forever to load in. UE4 even goes to “not responding” but if I wait long enough the asset will eventually load in.

I get “Loading Package …blah blah” and like I said it eventually loads in but it can take upwards of 5-10mins. Is there anyway around this or is this an known issue.

Hi BearsAirz!

This pack is pretty huge compared to others on the Marketplace. I believe it is 6gb of content to load. Reason why it takes so long for anyone. Unfortunately, there is not much around this other than loading only the editor, but only then the pack will still take longer than others to load.

I found this post from Tim:

This is actually necessary and can
happen on some meshes depending on
their complexity and texture
resolutions. When the asset is opened
for the first time it’s writing to the
DerivedDataCache to make it’s load
much quicker when reopening the
project or asset.

As an example, if you were to grab the
Open World Content that Epic released
for free a couple months ago that is
just some sample assets from our Kite
World demo it explicitly had the
warning in there that the initial load
of these assets could take a while to
open while the DerivedDataCache is
written.

Largely this can depend on system
specs to a certain extent. That
content, even on our machines here at
Epic that are high-end, can take a
little while to load the first time.

I hope this helps.

i encounter the same problem, the progress stucked at 70% and cpu usage is about 15%…
Deleting the “HillTree_02” folder can solve this.
