@Jason613 I have tested this for you and can confirm the crash.
Please submit a bug report through the X-Particles Menu > Support > Report Bug and our Developers will take a look at this.
Please ensure that the bug report includes as much information as possible, including your example scene file.
@Eduard_1992 We have tested this with the standard Cinema 4D Renderer, Cycles 4D and Redshift and are unable to replicate the issue using any of these systems.
Unfortunately, this does look to be an Octane issue.
Thanks @Eduard_1992 - we have looked at this for you and can confirm that this is working correctly in both Cycles 4D and Cinema 4D Standard renderer.
As such, this appears to be an issue with Octane and we would recommend contacting their support team for advice.
If you need anything further after contacting them, please let us know.
Thanks for confirming your system specifications @hoic.
In order for our Developers to follow this up, please can you submit a Bug Report through the X-Particles Menu > Support > Report Bug.
Please include your system specifications and this will go directly to the development team.
@ricktowersOnly one can be installed at a time, however, if you install the Beta, your system will automatically create a backup of the previously installed version so that this can be reinstalled easily.
