Hope the bugfixing will be end soon

FIXED:
- The subdivision precision is switched to a lower level to be compatible to MentalRay.
- Extend the shader check to check connected ports which share the same input shader.
MANUAL
- The on-line manual is available at http://render.otoy.com/manuals/Softimage/
- Please follow the installation instructions in the on-line manual.

Have fun with testing,
