Probably not new in this build, but i had my renders ruined with a VDB that has volume emission enabled.
When a mesh with a medium intersects the voxels, i get very strange artifacts. Octane really is super glitchy and slow with volumes.. Either the volumes intersect themselves, or they cause ...

Broken and unusable for me too.

i have the same issue at the moment.
A few hair objects and alembics in the scene - fully cached. It takes 8min to prepare at frame 1000+, which increases our rendering costs dramatically.
With octane disabled it renders instantly.

Statusbar says: Octane:>> ProcessUpdate(flags=M cAsyn=0 dDelay=0 ...

Thanks for your reply.
C4D Hair works as well? I rely on the c4d hair mat for the styling, will that get baked into orbx?

Ill render a pretty big project soon with fairly big scenes containing hair sims and many instances.
Is it possible to use the take system for RNDR now & render cinema 4D hair objects?
If not, I will look into other options

2020.1.5-R4 and still an issue.....

We know that we can use overlapping VDB's, but the required step length setting multiplies rendertimes by 100x.
Any updates on this?
