Hi Beanzvision, I've 3 Mac with Mojave installed :
1 - MacPro (mi-2010) with RADEON RX 580
2 - MacBook Pro (mi-2012)
3 - iMac Pro (2017)
The hair plugin worked perfectly with Corona 6 but since than I tried the daily v7 it crash Cinema 4D on these 3 machines.
I put on new scene a sphere go to Corona Hair plugin then clic on interactive rendering and Cinema 4D crash...
I also tried to put an hair material directly from the new material library but it's the same crash.
I hope it's enough for you to understand ;-)
I already clean re-installed Os Mojave and Corona but change nothing.
Thanks for help me please, I use all the time the Hair plugin for generate grass, now it's bit less realistic with displacement material.
Regards,
Chrys
