Hi guys,
I have rendered this panorama on interior high. The image itself looks very sharp but when sent off to the panorama viewer it is blurry. What have I done wrong?!
I have pasted the link to the viewer below and attached the render.
Thanks so much for your help.
Cheers,
Manuela

Your resolution isn’t high enough :)

Oh I see 😉
Any chance of helping out this novice and telling me what kind of resolution I should be aiming for with panoramas?
A middle point for clarity but not rendering until the ends of time.
Thanks so much!

It really depends on what device you want to view the panorama on, the specification of your machine, and the complexity of the scene. If you have a 4K screen, you are going to need a much higher resolution.

4000x2000 is quite a common resolution, and it's a pretty good starting point for most people. Obviously you will get better (sharper) results from a higher resolution, but that will have a corresponding hit in terms of render time.

Your pano might look good on a smaller screen like an iphone as is.

I typically use 5000/ 2500 but I know Nat (who has some of the best panos) uses 8000/4000.  Ofcourse this will take a lot longer to render than a still image.  But as Big Stick says, start out 4000/2000. 
Also note, the Panorama is rendering everything behind the camera which will also take longer to render.  In other in perspective camera views, Podium does a calculation of the entire model, but it does not apply raytracing and resampling to items that are out of camea view  (correct if I'm wrong Jim)

But for panos that is not the case, so that will increase render times.

But the end result is well worth it.

Tip - use reset tilt so the Pano does not look tilted.

Dave is right - the render engine calculates the illumination in the entire scene, but only applies the image processing features to the render. 

I think that the render time for a pano image and a non-pano image of the same resolution should be comparable.

For best results, put the camera right in the centre of the scene, and make sure you use reset tilt or 2 point perspective.
