# CGCG Mesh Info plugin for Maya
The plugin is use to generate SHA1 hash from mesh data (vertex, uvs, point) for comparing

### Command References
```
Synopsis: meshInfo [flags] [String...]
Flags:
   -q -query
 -ets -extendToShape  
   -f -file            String
  -ni -noIntermediate 
 -pth -ptHash         
 -ust -unset          
 -uvh -uvHash         
  -vh -vtxHash        
```

### Generate Hash Data
*`-vh, -vtxHash`* Mesh vertices  
*`-uvh, -uvHash`* Mesh uvs  
*`-pth, -ptHash`* Mesh point position (object space)

### Unset Face Ids (`-unset`)
*`-unset`* This argument is query unset color sets face ids on mesh, use for **`AbcExport`** with *`-writeColorSets`* argument, to remove vertex color on unset face ids.

### Examples
Generate vertcies hash from specify mesh
```python
import maya.cmds as cmds
cmds.meshInfo('pCubeShape1', q=True, vtxHash=True)
# Result: a68ebf8ed559d32ee4ad702599acb0f38d3a4a90 # 
```

Generate uv hash from specify mesh
```python
import maya.cmds as cmds
cmds.meshInfo('pCubeShape1', q=True, uvHash=True)
# Result: af2c9eff5f535b52f8b12332e900debb579a3bee # 
```

Dump all mesh without intemediate objects hashs into json file 
```python
import maya.cmds as cmds
cmds.meshInfo(vtxHash=True, uvHash=True, ptHash=True, noIntermediate=True
              file='C:/Temp/mesh_info.json')
# Mesh info file exported : C:/Temp/mesh_info.json # 
```
