Pipeline 3D Export Tool Requirements¶

This page lists the requirements for creating export tools for 3D data which can be used by the pipeline.

An export tool would be either one of the following:

• A console tool that can be executed once per input file
• An interface for inter-process communication that commands a running 3d modeling application process
• A tool that commands a 3d modeling application to process many input files in batch (Not recommended, as it does not provide sufficiently flexible feedback)
  And needs to accept the export modes with their respective input parameters, and output all of the requested files.

Export modes¶

shape	1 -> many	shape; anim; tga (lightmap)
ig	1 -> many	ig
skel	1 -> 1	skel
clod
cmb
pacs_prim
swt
veget
zone

shape¶

Exports:

• All shape nodes with lod (shape_with_coarse_mesh/nodename.shape)
• All shape nodes without lod (shape_not_optimized/nodename.shape)
• Animations per shape if any (shape_anim/nodename.anim)
• Generates lightmaps (LM) if required per shape per lightgroup (shape_lightmap_not_optimized/filename_nodename_lightgroupid.tga & filename_nodename.txt (log))
  • We might want to modify this to export the data required for a lightmap generation tool only to a data file, and run a lightmap generation tool outside of the 3d export process, that uses the exported shape and light information from the data file. See calc_lm*.* files under nel_mesh_lib.

Does not export:

• Accelerator
• Zone quad patch
• Particle system
• PACS Primitive
• Node properties DONOTEXPORT checked
• Node properties COLLISION checked
• Node properties COLLISION_EXTERIOR checked

Shapes may be:

• Particle system (???)
• Wave maker
• Node properties USE_REMANENCE checked (what is this?)
• Flare
• Triangle object

Triangle object may be:

• Water shape
• Shape with lod
• Shape without lod

Input parameters:

• LogErrorFile
• LogDependFile
• SrcFile
• DstDirectoryWithoutCoarseMesh
• DstDirectoryWithCoarseMesh
• DstDirectoryLightmap
• DstDirectoryAnim
• OptExportLighting
• OptShadow
• OptLightingLimit
• OptLumelSize
• OptOversampling
• OptLightmapLog

ig¶

Exports:

• All instance groups for IGNAME used in node properties (igname.ig)

Instance groups contain:

• All shapes (by name)
• All lights
• All helpers

skel¶

Exports:

• One skeleton containing node tree in reference position starting from node Bip01 (filename.skel)
