LScript Pipeline

Download

An LScript port of the LightWave 3D™ SDK pipeline sample. Analyse the behavior of execution timing.


Installation:

- copy pipeline.lsi to Newtek\LScripts
- copy expressions\library.ls to Newtek\LScripts\expressions\library.ls
- copy directory pipeline to directory Newtek\LScripts\pipeline
(Newtek = your LightWave installation directory)

- Create Scene FPS = 5

- Load cube.lwo
- apply or.ls as replace script
- apply cf.ls as channel script on Position.X
- create new expression value: pipeline() apply to Position.Y
- apply co.ls as custom script
- apply dm_pb.ls, dm_ob.ls, dm_wo.ls as displace script
- apply ia.ls, ia_afterIK.ls as motion script
- apply pt.ls as shader script

- apply if.ls to scene as image script
- apply mc.ls to scene as master script

- save all objects, save scene

- the Logfile LSPipeline.txt will be saved to the content directory


Settings which affect Render Timing:

- Motion Blur
- Field Rendering

Settings which affect Layout's interactive behavior:

- Show Motion Paths
- Dynamic Update
- Graph Editor is opened/closed
- lw3.cfg setting -> QuickMotionPathFrames
