Importing UT3 packages to UDK?

[maj86]

I tried copying the .upk files from UT3 and that did not work because the textures gave a null error giving many of the static meshes the default checker texture. I have also tried to open the UT3 .upk files through the generic browser and the same errors occur.

Is there any way to successfully import UT3 packages to UDK?

I don't recommend doing this BUT.

I copied all of the UT3 packages from /environments and /effects to the corresponding folder in the /UDK folder to see what would happen. Overwrote the existing files. Opened my map. All the Epic assets in my map opened fine, but the assets from my .upk package were showing up as null.

So I moved my .upk file out of /my documents/ and into /UDK into the /environments folder. Loaded that .upk into the content browser manually. Re-loaded my level -- everything came through (well, minus some prefab stuff and a few effects). Saved that map out after clicking through a bunch of error messages.

So yeah, you can basically pull in the base geometry and lights but you're going to lose a lot in the conversion. Plus lord knows if other people with the UDK can play your cooked map when you're referencing assets that aren't in their package files.

I did it for the purpose of re-lighting my lap in Lightmass and dag it looks good.

*Reminds self to backup before trying,

thanks for the info :D

It would be great if this was added in future builds of UDK. Seems like a lot of people want to import the static meshes from UT3 to UDK. For now I will give the above a shot.

Yea most UT3 maps I try to open just crash the editor. Is there some way to get effects / emitters from a custom cooked ut3 package into udk or should I just go back to the UT3 editor and learn how they made it and create my own textures?
