Extracting frame range from Houdini Alembic cache using pyalembic


Recommended Posts

Wondering if anyone else has run into this issue and has any alternate suggestions.

 

We access alembic cache information using pyalembic's cask wrapper.

For houdini alembic caches we get start and end frames of 0.0.

For Maya's alembic caches we get correct start and end frames .

According to the pyalembic docs [http://docs.alembic.io/python/cask.html#module-cask]:

time_range()

Returns a tuple of the global start and end time in seconds.

** Depends on the X.samples property being set on the Top node, which is currently being written by Maya only. **

 

So it appears Maya writes this X.samples property on the Top node which Houdini does not do.

 

Does anyone have alternate suggestions for extracting the start and end frames from houdini alembic caches using pyalembic?
