Does selling individual assets, content packs and starter kits require a commercial UDK license?

No. You do not need a commercial UDK license nor will the assets, content packs or starter kits be subject to the standard UDK royalty.

Scenario 1 – An individual creates a weapon pack consisting of meshes, textures, materials, particle effects and UnrealScript files; everything needed to drop the weapons into UDK for use in developing a game. The individual decides to sell the weapon pack through a content marketplace and earns US$75,000 (after any fees imposed by the marketplace) over a period of several years. No commercial UDK license or royalty is required and the individual keeps the entire US$75,000.

Scenario 2 – A team is creating a real-time strategy game. During development, they decide to sell the framework of the game as a “starter kit” that includes a collection of UnrealScript files and some simple stand-in art assets. The team is not required to purchase a commercial UDK license prior to selling the starter kit; however, the team would be required to purchase a royalty-bearing commercial UDK license prior to selling the full game they are developing. They charge US$150 per asset pack and sell 350 starter kits, earning a total of US$52,500. No royalty payment is required and the team keeps the US$52,500.

Scenario 3 – A technical artist creates freelance art assets (materials, particle effects, etc.) for several different teams all working on games using UDK, which are later sold commercially. The artist is paid a total of US$62,500 for their work. The artist is not required to purchase a commercial UDK license or pay royalties and keeps the whole US$62,500. The teams selling the games using the assets created by the artist are required to purchase royalty-bearing commercial UDK licenses and pay royalties on their revenue over US$50,000.

It sounds like Epic would be open to making some sort of a custom license agreement with AAA Games, but they would either need a commercial UDK license, or an UE3 license (which they already have).

Who do I contact with questions not answered here?

If you have any questions about licensing UDK or require custom license terms, source code licenses, or use on consoles please email udklicensing@epicgames.com for more information.

The T2 team has probably already contacted them about this, and may have more to add to this thread.

we'll all have to buy the commercial license before we can do anything about it.

On UDK site they say:

The individual decides to sell the weapon pack through a content marketplace and earns US$75,000 (after any fees imposed by the marketplace) over a period of several years.

So no, you don't need commercial license for it.

I was about to download it... now that i see its 1.8 gb... ouch? My internet is limited to 50 gb per month, and we've got relatives comming over... surely, i won't be downloading this anytime soon, probably febuary or so...

You got a friend and a USB drive?

I can't use it for create map anymore bacause UDK Source of download files is very big, i have no idea to buy a new one for upgrade my hard disk with more spaces. Also my PC was old and can't support this software. But i only accept for using GtkRadiant to create maps for Trem.   

Are Trem 2 can support old processor and graphics?? My graphic is NVIDIA GeForce FX 5500 (FX Series, as version 5. Released in 2003) and Intel Pentium 4 [2.4GHz].

BillyRazOr: system requirements will be announced later, but I fear that GeForce FX 5500 is too old.

You really need a new computer >.>

Nvidia FX5500 lol it barely can handle UT2004. Pentium 4 clocked on 2.4 GHz is minimal requirement.

Go out and buy yourself a new Linux machine as well. (Or Mac if you are lazy and don't want to be bothered with Wine or certain things not quite working)

Yes and no.
Friends: yes
USB : yes
Friends accessable: no [I live too far, this is australia after all, for americans its like texas and utah i assume]
USB Space [or hard disk space]: USB is a 1 gb usb. Actually it's an mp3 player with an upside down usb male port and a microphone with a built-in antenna for radio with tripple A battery slots for power.
Hard disk, well i don't have a portable one with space, and the others that do have space are backup hard drives for my family.
