= Art - Reference = If you are an artist and want to join/help our project, this article will mostly cover creating 3D-models and textures.<br> However there is almost always a need for more artists, so have a look around for other tasks you can do! '''There is an <b>upload form</b> for files (art,patches..) available :''' http://ghoulsblade.schattenkind.net/iris/upload.php * ~TODO add [http://www.mediawiki.org/wiki/Extension:Anysite Anysite Extension] to embed upload page? == Specifications for Static 3D-Models == '''3D-Models:''' * Walls/Windows/Stairs etc.: ~12-100 Triangles * Statues: ~300-1500 Triangles * Tables/Chests: ~100 Triangles '''LOD creation rules:''' Every object above 300 Triangles must have at least two LODs (LOD0 and LOD1) with LOD1 around 150 triangles. reduce material IDs. more important than removing polygons is the reduction of material ids on your objects. Ideally the last LOD has only one render material ID assigned. The difference in polygons from one LOD to the next step should be around 50% (1200 - 600 - 300). '''Textures:''' * Size: ~512x512 (but can be any Size ... think of using one Texture for more Models using UVM) * Format: tga/dds/png * 24-bit truecolor images with an 8-bit alpha channel '''Sample:''' Download: [http://sience.schattenkind.net/box_orientation.zip box_orientation.zip]<br> * The Box is 1 Tile size.
