Packages Not Staying Loaded

[Imatk]

When I load a package and then close UDK and then open it, my package does not stay loaded.

Anyone know why that would be?

What do you mean exactly?

When opening the editor all of the packages will not be fully loaded. Only the assets that are needed will be loaded. This saves on memory.

If you mean that the thumbnails aren't showing up, you need to let the editor update your asset database (that message that pops up sometimes when you open the editor - click "check now"). Then after it's updated, when you load UDK your assets will appear in the package so you can see them without going "fully load", then they will be loaded as needed.
