Hi Elden,
as you can read here:
https://render.otoy.com/forum/viewtopic.php?f=80&t=68122Octane V4 is a TEST release with new features implemented, so some issues are expected.
Please note that this release is based on Octane V4 XB3, and is not recommended for production work :
As with all experimental and test releases, please do not use this build for production work, and please note that we still classify this as an experimental release.
We cannot guarantee that scenes saved with this version would be compatible with future releases.
If you want test Octane V4, don't overwrite your Octane V3 file, make a copy.
Regards
Paride
