mGeo Exporter v1.0

Overview

mGeo Exporterscript is designed to export Polygons , NURBS, Curves and Particles with any Attribute from Maya to Houdini.

Key features

• Utilises JSON GEO as intermediary format to convert data to BGEO format that Houdini can read natively. Using a small utility called gconvert, that is installed with Houdini.
• Allows you to save Polygons , NURBS, Curves and Particles types all in one file.
• Using Pivots mode you can store any DAG Object as a point with transformations (translation, orientation, scale) and any arbitrary attributes, This is especially useful for transferring large number of copied of instanced Objects.
• Animation transfer in MDD format or sequence of BGEO files.
• Additionally you can create and assign Objects and Points to Groups based on specific criteria. Groups will carry through and work like you expect them in Houdini.
• Export settings are embedded in scene file as export sets

Geometry saving options

• Polygons
  • Create primitive groups based on following criterias :
    • assigned material
    • object name
    • shape- node name
    • name of the parent node
    • layer name
  • Read any attributes and record them as primitive attributes.
  • Export vertex attributes : UV, Vertex Color, Vertex Normal, Edge Crease
• Curves
  • Export as NURBS curves or Poly Line
  • Primitive Groups criterias :
    • object name
    • name of the parent node
    • display layer name
• Particles
  • Transfer any attributes with particle or particle system node
  • Create point- groups based on particle or emitter
• Pivots
  • add any attribute to pivot points as point attributes
  • adding attributes orient and scale, ready for use with CopySOP
  • Pivot Groups criterias :
    • object name
    • shape- node name
    • name of the parent node

Quick demo

Install

1. For Maya version older than 2014 install first PyQt
2. Download mGeo Exporter v1.0
3. Decompress pw_mGeo folder to your PYTHONPATH

\Python\Lib\site-packages\

4. In Script Editor (Python tab) execute following code

import pw_mGeo
pw_mGeo.show()

mGeo Exporter has been tested on following platforms:

• Maya 2013 x64 Windows 7
• Maya 2014 x64 Windows 7
• Maya 2015 Windows 7
• Maya 2014 OSX 10.9.1

Questions, suggestions, bug reports can be written in Comments area.

Plans for future: Improvements in area of working with Attributes.

Add more functionality. Add support for presets etc. As long as the script is useful it will be developed and evolve. Last but not least I would like to Thank Алексей (Somesanctus) Смоленчук, for helping me.
