I have 24GB GPUs in my system.
When I start C4D with CentiLeo installed, it takes around 3 GB of Vram from the system at the start in C4D.
This is without it being activated as renderer!

I would opt for a mechanism that activates CentiLeo only if you have chosen it as a render engine. Or right before rendering.

Reason:
If I want to render with Redshift or Octane (or any other Vram hungry renderer / application) I have around 3GB Vram less at my disposal.
I understand that CentiLeo might need that amount of Vram to run properly. But I t should not take it at the application startup. Only when it´s clear that the user is really using it!

Thank you very much in advance for considering!
