- How can I load OpenVDB files with correct scaling and translation
Dear Blender community, I have been trying to use Blender to visualize molecules and volumetric data from molecular dynamics simulation I managed to save my data in OpenVDB format using the pyopen
- volumetrics - import VDB file and start the animation at a certain . . .
It is actually quite simple, in the settings for the OpenVDB File there is a Start value This is the one on which you want the simulation to start If you hover your mouse over it, the appearing tooltip says: "Global starting frame of the sequence, assuming first has a #1" That sounds a bit mysterious maybe, it means if your sequence starts with 1, this starting point will be placed on the
- Visualizing RGB openVDB volumes - Blender Stack Exchange
I have 3D-volumes where each voxel is associated to a RGBA color, I use the following code to convert numpy arrays (of shape [128, 128, 128, 4], RGBA) to openVDB files: import pyopenvdb as vdb def
- Numpy array to openvdb conversion returns a shuffled volume
The hypothesis stating that the issue arises from the numpy array to openvdb object conversion is still holding I if you have any idea as to how I could debug this conversion process I would happily take your suggestions

I was trying to render out a sequence with OpenVDBs imported from Houdini and all of a sudden Cycles stopped rendering out the actual volume but only the reflections caused by it along with my mode

*For more detailed information; see below I am working with (OpenVDB) volumes in Blender, which I use to create animations This is an example: Both sides are different vdb files Now, I want to
- Is is possible to use grid volume as 3D texture?
I have been able to convert and import 3D MRI brain image in Blender 3 2 2 using OpenVDB format The result is a volume grid Now, I would like to be able to use this volume grid (in fixed world coordinates) to make the texture of a mesh in order to see slices of my MRI volume
- Import OpenVDB files? - Blender Stack Exchange
Is there any way to import OpenVDB files into Blender for rendering, exported from Houdini? Will there be an option in Blender 2 8 (stable) or is there any other build that supports Houdini's vdb
