This example demonstrates rename of a joint.
|
||
|
|
- usage in command line:
|
||
|
|
- call without arguments:
|
||
|
|
python rename_joint_demo.py
|
||
|
|
mayapy rename_joint_demo.py
|
||
|
|
|
||
|
|
Expected: Script will generate Ada_new.dna in OUTPUT_DIR.
|
||
|
|
- usage in Maya:
|
||
|
|
1. copy whole content of this file to Maya Script Editor
|
||
|
|
2. change value of ROOT_DIR to absolute path of dna_calibration, e.g. `c:/dna_calibration` in Windows or `/home/user/dna_calibration`. Important:
|
||
|
|
Use `/` (forward slash), because Maya uses forward slashes in path.
|
||
|
|
- customization:
|
||
|
|
- change value of DNA to Taro, or name of file which is copied to /data/dna
|
||
|
|
|
||
|
|
NOTE: If running on Linux, please make sure to append the LD_LIBRARY_PATH with absolute path to the lib/linux directory before running the example:
|
||
|
|
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<path-to-lib-linux-dir>
