UNREAL TECHNOLOGY

Doing some research into the ureal engine ive come across this for anyone who is doing a character in their project so i thought i would share it with everyone. If anyone has any more info please let us know?

Typical Content Specifications

Here are the guidelines we're using in building content for our next Unreal Engine 3 based game. Different genres of games will have widely varying expectations of player counts, scene size, and performance, so these specifications should be regarded as one data point for one project rather than hard requirements for all.

Characters

For every major character and static mesh asset, we build two versions of the geometry: a renderable mesh with unique UV coordinates, and a detail mesh containing only geometry. We run the two meshes through the Unreal Engine 3 preprocessing tool and generate a high-res normal map for the renderable mesh, based on analyzing all of the geometry in the detail mesh.
Renderable Mesh: We build renderable meshes with 3,000-12,000 triangles, based on the expectation of 5-20 visible characters in a game scene.
Detail Mesh: We build 1-8 million triangle detail meshes for typical characters. This is quite sufficient for generating 1-2 normal maps of resolution 2048x2048 per character.
Bones: The highest LOD version of our characters typically have 100-200 bones, and include articulated faces, hands, and fingers.

Normal Maps & Texture maps

We are authoring most character and world normal maps and texture maps at 2048x2048 resolution. We feel this is a good target for games running on mid-range PC's in the 2006 timeframe. Next-generation consoles may require reducing texture resolution by 2X, and low-end PC's up to 4X, depending on texture count and scene complexity.

Dave has asked me to put the URL in here so everyone can see where i got it from so here it is. It lists everything that anyone needs to know what is required to importing your finished models into the Unreal engine.

Nice one Ste, add the source of the reference for everyone.
