Regarding the crash with Octane, the crash happens on Octane, not Ornatrix. So we have to wait for Octane devs to fix it. They have been modified about this issue. However, a couple users on our Facebook group reported that it doesn't crash anymore on latest builds of Octane.
I'm sorry that you didn't have an optimal experience with Ornatrix version 1 for C4D. In the case of version 1, it is not under development anymore, but the development of version 2 is very active and alive. If you decide to upgrade, please report any issues that you can find during production and we will do our best to fix them all.
Regarding the upgrade, we offer upgrade discounts and free upgrades depending on when you bought Ornatrix. You can find more information in our documentation here. In your case, a 25% discount applies if you decide to upgrade.
