“Shadows ignore user defined clipping planes” doesn’t work in the current Rhino 8 WIP. Can anyone confirm if there is a bug?

It still doesn’t work in the Rhino 8.1.
Likely it is a bug

Yes, and it’s a regression. I just checked the new release candidate, it’s still here. I think regressions should have a priority in being fixed.
It will be solved. Moving targets here being tackled by the team.
@stevebaer can you look into this one?
Hi -
That’s a bug, yes. I’ve put this on the list as RH-78193 Display: Shadows to ignore clipping planes
-wim
Please, can you give this regression some priority on Windows? It still doesn’t work in 8.6.24074. Very soon I will need this functionality and this is broken since at least October. 
It was reported before Rhino 8 went out of beta… (October 18 / October 31)
Hi Barden -
RH-78193 was fixed on November 9th.
If you are running into something with 8.6, I’ll need detail to try to reproduce that here.

Hi,
I can reproduce this also and actually, I also need this working.

Thanks, that’s exactly it. I have the same results with your file.
Can some another user with Rhino 8.5 or 8.6.24074 check if “Shadows ignore user defined clipping planes” works, please? I would really appreciate knowing if it’s really broken again.
If it’s not working, please reopen the YouTrack issue.
I can confirm that it doesn’t work here either 
Hi, Can you please check this file or just put 1 box and 1 clipping plane in the Rhino?
All you need to do is to set “Shadows ignore user defined clipping planes” ON in the Rendered mode and set some light to check whether shadow is made by clipped geometry or full object.
It’s important and if it doesn’t work for you as for the other users, please reopen the YouTrack item.
@jeff
This does look broken for the Rendered display mode…I’ll take a look.
I do want to point out here though, that this is not going to work for Raytraced display modes…and it currently will not work in Mac Rhino’s Rendered mode…until I can get to it.
Thanks,
-Jeff

Thank you! Fortunatelly, I’m using Windows and do not render in Rhino. Rendered mode is all I need to just look how sun rays behave. I hope it can be fixed soon, because I can’t afford going with my work back to Rhino 7…
It appears that this was broken in 8.5… so at the very worst case, you could roll back to 8.4…

This will be fixed in the 8.6 Service Release (SR6).
Thanks,
-Jeff
