working with pano renders and i have a sun in my environment background image. i don't want the octane sun to show up, but still want it to cast light. tried size 0 but still shows up. any ideas?

I don't know a function to hide the sun in the Octane physical sky. Perhaps you could render the environment pass and remove it in post.

I don't know how to do that! no experiance with render passes.. and the not being able to hide the sun totally messes up spherical images.. as the sun streaks do not carry over to other side of the frame. i see you can change the number of ray count, i put to 0 and there is still 1.. if it would actually be 0 it would fix my issue

and i am working on animated 360 videos, so taking out in post, would not be fun.. unless it could be automated somehow

Then perhaps your best chance is to use an HDRI sky texture environment. You could remove the sun from the HDRI texture with any paint program, and use a Octane light unseen by camera to simulate the sun light in the scene, if you need it.

I am using an HDRI texture for the environment. However the animation "camera moves in the panoramic animation" is over 1500 frames.. taking out the octane sun with paint for 1500 frames? whew that's a job!

guess i can listen to that while i painstakingly Photoshop the sun out of each image lol

Why not render with alpha, and comp bg in AE?

But if you are lighting the scene with an HDRI texture, why are you using the daylight environment node?, to have a direct sun light in the scene? ... what I was thinking is to use a real life skylight HDRI texture environment map (perhaps with the sun removed with a paint program if you don't want to see it), and use an Octane light to simulate the sun direct light.

Something like this setup, a sunless HDRI environment and a Octane light unseen by camera to simulate the sun light. This is a daylight lighting with an invisible sun
