Panorama Exporter stitching renders wrong

[Anonymous]

Hello, 

My objective was to produce a mini gallery and export it as a spherical panorama. Everything worked as intended until I noticed a few issues post-render. Using a "Free" camera, the stitching is done correctly, but the panorama is not aligned horizontally (see second figure). I've noticed rotating the camera reduces this issue in certain views, but greatly affects a different view (i.e. Forward view is aligned, but the left and right view are greatly misaligned). 

I switched to a Physical Camera to check if there was any differences and turns out, there are. The physical camera renders every view aligned in a horizontal line, but for some reason it does not stich seamlessly (see first figure). I've seen it work for other people, but it's not working for me. 

Is there a way to fix this problem?

Thanks in advance.

Hello @Anonymous ,

I'm not an avid Arnold user but the age of stitching panos together is thankfully behind us in 3D.  Nowadays most if not all advanced renderers come with something called a spherical camera which takes care of all this for you.  Here's the blurb for Arnold.  

Otherwise, the problem with your camera is possibly related to aperture width (F10->Common->Output Size->Custom->Set Aperture Width), FOV, or the relationship between them.  I'd try the spherical camera first.

Thank you for the response, I was not aware of the spherical camera, it produced the results I desired 🙂 I did also revise the settings of the camera I was previously using and it was indeed an Aperture Width issue.

Nice.  Glad it's all working out for you.  Thanks for the update!
