There is a small bug occurring in V6/V7 Mac as well as in Windows (I believe):
Steps to reproduce:
ground-plane settings and set them to shadows onlyNot a huge bug, but a bit annoying…
Cheers, Rudi
I am unable to repeat that in V7 Mac or Windows.
Normally the Ground Plane in Rendered display mode follows the current Render settings.
Have you diddled the settings in Rendered?
I tested this with pure default settings.
The must be more to this puzzle than you have reported so far.
What tool are you using to turn off the Ground Plane?
I’m using the Ground Plane in the Inspector panels.
Interesting… I can even reproduce this bug with importing a simple box.
I applied the Reset To Defaults in the Rendering panel and also applied the ground plane settings there as can be seen in the screenshot attached.

Did you save the file after the change to shadows only? I think so but the video was too low res to see. I haven’t been able to reproduce this either yet here but will try again.
Do you have multiple Rhino’s open too? This hasn’t caused it to happen here but just checking.
Hey Brian,
I saved the file after making the change and closed it then. Also had only one Rhino opened.
Hope this helps 
Thanks, I tried the same but can’t reproduce what you showed. I wonder if it has to do with any specific block or Plist setting (your Rhino for Mac preferences file). Have you tried resetting the Plist? You can make a copy of it first so that you can replace it again if it doesn’t make a difference. Here’s the info on how to find and reset your Plist file. https://wiki.mcneel.com/rhino/mac/resetprefs
If you can post the actual block you Insert as well, I can try that too. Thanks.
Hey @BrianJ, excuse my very late response…
I tried the steps mentioned above, but issue is still here. Furthermore, after resetting the Render settings Rhino freezes every single time (after 10-20 seconds).
Here are some steps to reproduce this issue, took me some time to distill it to its minimum:
Open a RH file with two boxes (ground plane settings will probably be lost = white ground):
Model.3dm (3.0 MB)
where other two boxes are inserted as a Block:
Block.3dm (2.8 MB)
Make sure the background is set to Application settings in Rendered Preview:
reset Render settings:
wait 10-20 seconds. The application will freeze.
Hope this clarifies this bug!
Thanks a lot,
Rudi
Has anyone solved this problem? I seem to have the same bug in Rhino 7 on Windows. I set the ground plane to use the “show shadows only” effect, saved it, and closed Rhino. When I reopen it, the setting reverts back to “Use a Material.”
I suspect this has something to do with the block… or not? Does anyone have any ideas?
That setting is part of the Rhino 3dm file itself not a global setting. See if you can change it and then use SaveAsTemplate to save a new template 3dm file with the change. If that works, you can then change the template file you are starting with by overwriting it.
Yes, i believe it is part of 3dm file but still. When I save one small file, it remembers this setting so when I open it, the ground plane is set as it was after saving it.
But there is another file (with many blocks, materials ets - whole detailed bike) that, when I open it after saving whith setting “show shadows only.”, It opens back with deafult “Use a Material.”
Saving this fail with corret setting does not work either. And even if it worjed, the file has 176MB with bunch of layers etc… which does not make sense to save it as a template.
I have just found the bug, at least part of it!
In that file, I have had attached Solidworks parts and assemblies as linked blocks (to be able to update them when I change them in solidworks without replacing them in rhino). When I deleted those blocks, the ground saves correctly!
This is an old bug that I reported years ago and was given this same answer.
This is one of the reasons I gave up on using blocks for the most part; but still hoping McNeel can correct block bugs which are numerous. I still have the file and it still exhibits the same bug. It has to do with block/s somehow overwriting the shadow settings.
This is exactly what I have to do when I open my file that exhibits this same behavior and like you said if you delete the blocks and save the shadow settings are remembered. Also in any new file I create without blocks the groundplane shadow settings are remembered. Every time I open this one particular file with blocks I have to change the groundplane settings and even when I save the file with the newly set groundplane settings reopening the file opens like you posted forgetting my settings.
I’m on V7.

I tested the file on V8 and it works the same.
Thanks @dyzajn and @3dsynergy , I have reproduced this issue and filed it as https://mcneel.myjetbrains.com/youtrack/issue/RH-90703 for the developers.
Great work! Thank you!
Thanks that’s great you found it and are trying to fix it.
