Title: Corona & VDB or Alembic (integration with realflow)
Post by: 3dkobi on 2019-01-27, 15:21:45
Hi guys,
I'm about to start an animation project with realflow -I want to export the meshes of the water & foam from realflow to c4d via VDB or alembic. How does corona for c4d handles those files ?

Corona for 3ds Max does support loading OpenVDB files via the CoronaVolumeGrid but this is not yet added in Corona for C4D - as far as I know, there is no way to import OpenVDB files into Corona for C4D (unless any C4D native loading of OpenVDB works, but I doubt it unfortunately).

Thanks Tom, so I'll have to render this project with Vray

Hi, Im rendering a number of shots on a project at the moment, in C4D using Particles, i used a similar workflow with realflow.
• Using X-Particles to create liquid splashes.
• Exporting the Cached mesh as Alembic
• Merging the .abc alembic file into my scenes
• Applying corona materials to the .abc object

Hope that's of some use

Hi philistymon,
Actually it helps a lot :)
Just to understand the process - Export the meshes of the water & whitewater from Realflow as Alembic and Import to C4D - Than it becomes a C4D file which I can texture with every render engine ?

Cool, Yes, select the Meshed simulation, File-Export-Alembic, have a look at the options there, Frame Rate, number of frames etc, fairly intuitive. Save it to your HD.
Then either open, or merge to your existing scene. and you have an animated mesh. I use it for creating reusable things like splashes and liquid sims that can be recycled for other projects quickly. Good luck
