Stereo Camera Import

[jbashyam]

Does anyone know how I can import a stereo camera rig from Maya? Currently I am baking out the individual left and right cameras and bringing them into Terragen... however, once in Terragen the convergence doesn't seem to be correct. I am using the zero-parallax attribute in Maya, which seems to control the film back.

The only way I know how is to export the left and right cameras separately.

According to this:

the zero-parallax attribute offsets the film back when in Off-axis (default) mode. This information won't be transferred to Terragen because we don't currently support offset film back rendering. However, you could offset the images in X in the composite to give the same result (you just need a bit of padding on the left and right of the render). I've worked on some projects where we did this. It's useful because you can adjust convergence without re-rendering anything.

If you switch the camera to "Converged (toe-in)" mode, it should actually rotate the cameras, and since rotation is supported by Terragen it should work.

Awesome, the "converged" mode did the trick. Thanks for your help... I gotta say, you guys have really awesome customer support! Much appreciated.
