MAXScript101 5.3 ExportMesh - Writing Custom Scene Exporters

 

I. Biped Walk

1. create a bipe: create > system > biped;

2. create footsteps: 

(1) click motion, and select one part of the Biped. 

(2) under Biped rollout, select Footstep mode. 

(3) under Footstep Creation rollout, select Create Multiple Footsteps, in the dialogue, modify the Number of 

 

Footsteps and leave others default.

3.  create keys for the footsteps

with the footstep mode selected, under Footstep Operations, select Create Keys for Inactive Footsteps.

 

II. Custom Mesh Exporter

III. 注解：

1. 帧数与整数的转换

animationRange.end -- return 124f

(animationRange.end - animationRange.start).frame  -- return 124.0

 

2. 有关mesh的操作，参考MAXScript Reference, 可搜索关键字：getVert
