Hi exile,

your level may be created with blocks and models, sprites, static meshes. Since BSP is a A7 Pro feature for the scene manager, you should use the term "block based" to avoid confusion.

It should be a medium size level and until now I have no feedback about file sizes. Just tell your archive size and we will see if it is too large.

The theme should fit to UT2K4 - no racing game
It does not matter if it is a CTF map or not - it should have some flow. - no dead ends without reward, ...

Give your level a great flow and add some nice textures and detail models (made by your own) to it.

Make sure you have the right to give all the assets away to the cummunity for free.

Your level should run with A7 - just in case you used A6 long time ago to create this level.

Good luck
Michael
