stereo renders and image planes 2010年11月11日9:06

Hi,

First off I'll put forward that I've just started working in Houdini, so I don't know all the technical ins and outs only what I've been investigating regarding this topic.

I'm trying to render out stereo pairs using a Stereo Camera. This works fine and generates exr files with vm_filenamesuffix, from the left/right cameras in the stereo cam, appended to the appropriate eye of each frame.

I'm running into some problems when I add an extra image plane to the mantra node and then select for it to be directed to another filename. The problem is that it doesn't append the vm_filenamesuffix to the output exr's for the image plane. I was expecting it to make stereo pairs for these as well.

My question is: Is this expected behavior or not?

I've had a peek at the code and it seems as though the filename set in the mantra node using vm_picture (which will get the vm_filenamesuffix appended to it) is reset to the vm_filename_plane value, as it should, but then doesn't have the vm_filenamesuffix applied to it.

I haven't found any resources online describing how stereo and image planes work together in houdini, so at a bit of a loss.

As a side note: If I do not force the image_plane out to another file it bakes into the vm_picture exr's fine and of course on a per eye basis, but I am not trying to do this

I am using Houdini Apprentice 11.0.469.
