What's the best way to render only a portion of a spherical camera? For instance if I wanted a 90 degrees horizontal and 30 degrees vertical portion of a Spherical Camera?
I've tried, for instance, setting the FOV to 90 and setting my image aspect to .5:1. That works, but I'm a bit stumped on how to deal with the vertical aspect. I can use the -reg flag in batch to only render that region, but I still end up with an image that's larger than I wanted. Granted, those pixels are empty but we're dealing with some large resolutions so we'll end up specifying some huge number for the vertical resolution just to get a small percentage of image area in the middle of the image that we want.
I get the feeling we're going about it wrong. Maybe using an image for distortion?
Thanks.
