Static 3D-Tiles Specifications

3D-Tile:

• 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 than one 3D-Tile using UVM)
• Format: tga/dds/png
• 24-bit truecolor images with an 8-bit alpha channel

Sample:

Download: OrientationBox.zip

• The Box is 1 Tile size.

Before you export to ogre.mesh, you have to apply:

• 90° X rotation

NOTE: Some exporters, such as OgreMax, allow up-axis setting for exporting to mesh file.</i>

• Iris2 uses Z-Axis as "up".
• Ogre default is Y-Axis.

What Static 3D-Tiles do we need?

This is the most important Tool for artists to verfiy what is needed and what is already available!

• Item Model List and Walls
• Iris2 Art Tool which lists models and how often they occur Ingame.

Furthermore: If you create a directory with the name missing next to the iris binary (ie. c:\games\iris2\bin\missing ) and put "gDumpMissingModels = true" into you config.lua, iris will dump every missing art as a png (TILEID.png) into the missing directory during gameplay or offline mode.
