your model has bad eyes

Hi DEVs,

First of all thanks for BUG fixes form XB1 (both of my bugs are fixed now )

Although I have some questions about Hosek-Eilkie Sun system,
For better explanation I'm sending short video to show the problem/confusion so maybe someone from DEVs could jump in and explain what is going on there, why does new sun model so drastically change reflections in my scene.
Is this new behavior correct ?

Here is the video and ORBX scene and video.

Thanks and Happy NY .

Hi Lewis,

Thanks for the explanation of the difference you're seeing - the scene and video are really helpful. I think the result you're seeing is correct. The reflection is dim, but visible on a black background. On a bright sky background the reflection is overwhelmed by the brightness of the sky. This doesn't appear to be related to the daylight model chosen - I can get the same reflection effect using the Octane daylight model if I adjust the ground angles so that the relevant part of the sky is black. I can also see the reflection by changing the glass railing to a diffuse black material.

Thanks for answer karu, I suspected it might be ok due hemisphere vs full sphere but i just wasn't sure. Thanks for explanation/confirmation.

Hi @andrey.krivulya

Your issue has been fixed. Unfortunately it didn't make it into 2020.1 XB2 but it will be included in the next build.

For now just so you are aware this was an issue related to autofocus, so disabling it from your scene should not fix it completely but mitigate it significantly.

Thank you.

Hi, @mojave

Thank you for this fix.

OTOY team, can you please post a sample file for those Vectron Volume screenshots? I can't figure out how its done.

I know you guys are probably really busy, but is it possible to get a sample file showing us how Vectron Volumes are created?

We have updated the section regarding vectron volumes in the initial post with Lua script you can use as reference.

Thanks. I don't think anyone could have come up with this without an example script I hope this process will be simplified with a built in node that converts vectrons to volumes.

I don't even think my plugin (for modo) supports lua scripts
