Alembic camera from Maya

Hi guys,

 

What's the best setup to get alembic cameras into houdini? Currently using file> import > alembic scene, but I am left with no camera options.

 

I would like to control things like the near clipping, and be able to scale the camera based on the scene scale..

 

any pointers?

Hi Michael,

 

Thanks for your reply, do you mean creating a new camera and linking/setting is value from the alembic file?

 

Seems like a good think to try, just want to make sure I am approaching it the right way

 

Thanks,

C

you'd probably want to create an otl that wraps up the alembic transform node and a standard camera with the alembic dictionary queries.  you can do a standard import alembic (from the file menu) and then disassemble the parts you need, change the expressions in the camera to pull from a specified file, etc.

 

they really ought to have this stuff built into houdini.  the "import" model is just so not-houdini.

honestly I'd make one if I had the time ;)

 

what I'd do is make an HDA that just has a camera inside with a little null network for things like offsets etc

then a field to point to an abc file

everything can be extracted from the abc with python

 

ideally this rig would be your main camera, for key framed anim, imported data (abc, fbx) etc.

 

this way you can control how external formats are imported/exported
