Well, i'm probably missing something.

I'm trying to transfer VDB data from Houdini into C4D via the Octane Volume object VDB slot.
VDB loaded fine, and i can see the volume appears in Octane live viewer, but it is much less dense then VDB that generated inside C4D, via the Volume object or TFD.
Also, i need to put the VDB in Hectometers in order for it to be in the same size generated initially from C4D

So what am i missing? i made 2 videos:
1. Demonstrate my problem transferring VDB data from Houdini
2. Demonstrate how it is working properly with Octane Volume Object.

Ahmet, any idea what am i missing? maybe i'm not exporting the VDB right from Houdini? VDB file attached also.

Thanks.

Shouldn't You play a bit with kernel settigns for volume objects as well? Try to tweak some options thre (sorry do not remember, pelase consult feature thread) but I noticed that some of those helped during tests I've done!

Hi Yam,
here is my attempt with scattering only and a Volume step length of 0.01 in the kernel settings:
