记录一些基础的maya日常笔记

一些常用小代码

硬边选择

功能描述：按角度获取硬边

python

import maya.cmds as cmds
cmds.polySelectConstraint(m = 3, t = 0x8000, sm = 1)
sels = cmds.ls(sl = 1)
cmds.polySelectConstraint(sm = 0) #复原选择模式，不然在view中只能选择硬边
cmds.select(sels)

python3

import maya.cmds as cmds
cmds.polySelectConstraint(m=3, t=0x8000, sm=1)
sels = cmds.ls(sl=True)
cmds.polySelectConstraint(sm=0) #复原选择模式，不然在view中只能选择硬边
cmds.select(sels)

提取曲线

功能描述：从边提取曲线 polyEdgeToCurves

mel

polyToCurve -form 2 -degree 3 -conformToSmoothMeshPreview 1;

世界中心枢轴

功能描述：世界中心枢轴: 选择对象

mel

string $obj[]=`ls-sl`;
for($aObj in $obj)
{
xform -cp $aObj;//坐标刷新到自身中心
move -rpr 0 0 0 $aObj;
}
FreezeTransformations;//冻结变换-也就是位置信息为零
DeleteHistory;//清除历史
ResetTransformations;//重置变换-坐标归世界中心
OptimizeScene;//清理场景

固定FBX参数导出

功能描述：统一团队导出格式

mel

string $ObjectsSelected[] = `ls -sl`;             //--选择对象--//

float $ObjectsSize = size($ObjectsSelected);    //判读是否多个对象//
if($ObjectsSize > 1)
error "如果有多个对象,请把对象打组导出.";
if($ObjectsSize == 1)                           //等于1就执行导出//

SelectHierarchy;
DeleteHistory;              //按类型删除: 历史: 删除选定对象上的构建历史
