Issue rendering volume

[Andrea_Philippon]

Hi,

I searched a similar topic but couldnt find it so i hope you guys can help.

I created a scene and played with the VDB Volume. It renders pretty fast in the Octane Live Viewer And work fine but when i try to render using c4D export, it crash.

First i had this message : "Not enought memory" combined with "Octane pluggin crashed" so i cranked the memory up to 26k (it was 4 k) and only have the pluggin error message now.

After some tests to be sure that the problem is about the VDB Volume (and it is), there is one thing i cant figure out : Why it renders in seconds in the Live viewer and cant render using c4D export? I must have missed something.

Render in seconds in the Live viewport , and takes more than 6 mins + crash in c4D export

Spec (So i dont think my machine is the problem)

GTX titan X 12 Gb
32 Gb ram
4.5Ghz core

I stay around if you need some more details, i hope you can help, i love this stuff!!

Do you know what's the meaning of 10x multiplier for Render?

mmh No, sounds like this is my solution ahah. I'll have a look, do you recommend me a specific topic ?

I recommend that read and understand how voxels are handled in memory. See this page.

my advice to divide your volumes to smalls to avoid out-of-memory issues.

Thanks a lot! That was my problem, the multiplier was on 10.. so 10*10*10! A bit too much It's working very well now! Thanks again, i have a lot of fun playing with this
