Centileo takes GPU Vram at C4D startup, When I start Cinema 4D CentiLeo uses 3GB of Vram off the GPUs
 
Hey Kirgman,

sorry for the long time it took me to reply.
Thank you very much for your nice answer and for looking into my request.

It would be certainly interesting to see results of your experiments with CentiLeo and get the feedback about the current amount of issues.
Unfortunately for you I have not been building scenes or anything: I am playing around with it from time to time seeing what features are in there in rendering and in materials.
I have to say it looks very promising. I like the fluidity of the IPR and also the material system: There is quite a lot in there that allows to build sophisticated materials.

When I play some more with it and find things to report (good and bad) I will write them here :-)

About the forum message cutoff. I am certain this is half my fault. I tried to add the images (that I later then attached the link) to the message directly but could not figure out how. So I aborded the process. I guess this caused the cutoff in the end.

Cheers and a great weekend and a good time to you and thank you once more for your work and friendly replies!

Oh wow. What a nice welcome.
Thank you so much for your long message. Great to also hear that those research results were of some use to you!

--EDIT--
Huh, the forum posted only the very top of my message, so here I go again and hope this goes though this time:

Maybe to help the claim I made I uploaded some Screenshots of the Vram usage of my GPUs.

Base line is secondary GPUs 250 MB, main GPU 1400 MB

So when I start C4D without CentiLeo installed the Vram utilization is as follows.
Secondary GPUs 1000 MB, main GPU 3000 MB

02_C4D_Opening_CentiLeo.png
When I install CentiLeo and reopen C4D the Vram Usage increases:
Secondary GPUs 2700 MB, main GPU 6000 MB

So just opening C4D in the standard interface. Not touching anything.

Thank you very much for your prompt response and having a look at it.
Would be great if that initial Vram usage could be avoided.

Btw. I also had a look at your C4D Manual. It looks really nice. Congratulations.

Cheers and a great weekend to you!

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!
