Maya Alembic Export - Camera Workflow issues

[rotorstudios]

Hi Guys,

Just a note, we've been experiencing an issue when exporting animateded cameras from Maya (2015) to Octane Standalone 3.03.2.

We're rendering some pretty fluids, but because the Scene is so large (open landscape) it appears that the Alembic Exporter is baking in a non-infinite far clipping plane.
Changing the scale interp of the camera does increase the clipping plane but sends the transforms off into orbit.

Is there a way to expose the infinite clipping node of the camera? Alas only the near clip is exposed in the Maya plugin (using the v2 plugin)

Any tricks would be handy, otherwise I'll need to construct a 1/10th scale world to force it in.

Cheers,

Luke

Sorry guys, found the awesome Camera Exploder in the forums should have looked harder. This hits the spot.
God it feels so good to have access to the alembic camera attributes I need to LUA more often it seems.

My bad. This should also be in the bugs sub forum. Also my bad.

Afaik it's not really a bug, the Far clip depth attribute have been introduced recently in Octane 3 and didn't exist in V2,
as I understand for some reason your ABC camera doesn't default to infinity for this new attribute.

So yes one way to solve this issue is to use the camera-explode* or the ABCcamera2thin* script nodes to access the attribute.

Another way is to export the camera from Maya with export scene with merge alembic node disabled,
this way you get directly an animated camera object in standalone with access to all its parameters.
(one quirk with this method, you must set animation mode to full, else it doesn't work.)
