Hello @Redeemer,
Thank you for bringing this to our attention.
Could you please let us know your HW specs and SW versions? (you mentioned you were also using 3dsMax, so please include the version you're using)
On the other hand, I'm curious to know if you're using Corona 12, or the Hotfix 2, or the Update 1, which one are you using?
One last thing, could you please try entirely removing Corona (don't forget any leftover file), then upgrade your Cinema4D version to a more recent one (e.g., C4D 2023, or 2024, or 2025), then reinstall Corona and see if the issue persists?
Looking forward to hearing from you soon.
Have an amazing day/evening.
Kind regards.
