Alembic/particles not showing up with Octane tag

Wed Jun 24, 2020 2:42 pm

I have a 2.4gb alembic file with particles exported in Houdini, somehow the Octane tag keeps ignoring it when I enable particle rendering.
The alembic is working when I use octane scatter but it's not a solution for what I need to do, alembic has also been tested with redshift and works fine.

Anybody else has had this before?
I'm on 2020 in S22

Hi.
have you tried to import the alembic file into Standalone?
If the particles are not visible also there, an attribute is missing or differs in the .abc file, and octane cannot read the particles.
A workaround could be to try to use Thinking particles to transform the points in something that Octane can read.

Probably it's not supported/recognized type for the plugin.
Could you share a sample scene with us to check it? I can debug and look for what can be done!

Thanks, will do!
I will send you a link to download the alembic on mograph slack..

i had the same experience a couple of weeks before with a stitched huge single alembic-file ( foampass from realflow standalone) octane does not render the alembic-particles. at the end i switched to a monthly arnold-subscription: the capability to render a even a huge amount of particles is incredibble good! DOF, Motionblur everything works and with the new multi-GPU-support arnold renders reasonable fast. not fast as octane but it renders multimillion particle-sequences right out of the box without any problems. abolutely amazing and arnold also reads alembic-sequences without any problem.
in my opinion it makes zero sense to stitch a huge particle-Stimulation into one giant single alembicfile. it is much better and and way more efficient to load and render every single frame „on the fly“ but unfortunately octane (and redshift too) does not read alembic-sequences at all.
ahmed@ any chance to get this funcionality too in octane: reading alembic-sequences?

Redshift certainly does read Alembic sequences just fine.
