Help with Alembic camera and scene (again...)

[resmas]

I want to be able to edit the imported camera like I do with any other camera in Octane, so why it that not possible?

Because the camera is loaded from the Alembic file, and Octane won't modify the Alembic file. What we can do is add a function to convert the Alembic camera to a regular camera node, but then the camera won't be updated if you change the Alembic file with your 3D modelling application.

Hello all.

That looks a great option, then we would be able to render the animation with some camera tweaks and no need to return to 3d modeling software só many times just to adjust some camera changes.

I like to run the animation inside StansAlone, and change some settings, its great because i'm watching a live preview, as we can't change the camera setting i'm forced to go back many times to work in 3D software without Octane live preview, and set all things right.
The best Octane have is the ability to see in RealTime our changes.

If you guys can input that option of a octane camera settings linked to alembic animation would be Great

All the best to you all
Cheers

For my own, as reported in the release candidate section, I am still unable to get a decent usable camera from alembic export : the exported camera has an important jitter. The same animation rendered inside Blender with the plugin gives smooth camera animation.

As I also reported, I noticed that the image in the viewport has an important jitter when scrolling the shutter value with the mouse wheel. Maybe there is a bug in the camera motion blur. More noticeable at small shutter values.

I still have no answers on my first post in this thread, I cannot manage to export a camera animation from Maya, and having it match the scene, is anybody else having the same issue? I don't know what to do!

Can you post the different images you are getting? The environment appearing smaller or larger depends on the field of view of your camera, a wide angle field of view results in the environment appearing smaller. And the field of view is not affected by the scale.

If you are importing both an OBJ and Alembic file, are you connecting the geometry and the camera output of the Alembic node to a render target node?

Yes, they are both connected to the same render target, and it's not the FOV, that is correct, it's like the camera I export and the scene are slightly shifted, I'll show you an example:

this is what I have in Maya

And this is how appears in Octane

Here is the file, sou you can help me solve this problem (the scene is for Maya 2013, requires VRay)

OK, we found the problem, it's a bug in the camera importer. I will make a test build later today, so you can test if it fixes your problem.

Hi Roeland, what about the problem of camera jitter ?

[roeland]

OK, the test build is up here:

64-bit Windows test build
