Here´s a short video that shows a workflow to get vdb files into touchdesigner.
I use Embergen and a preset that comes with it to export a simulation to vdb files;
Next i import them in Blender, use a single point mesh with the volume to mesh modifier.
I adjust the mesh size via voxel count and export everything to an obj sequence;
(fyi only density information of the vdb files is exported in this example.)
the obj files have position and normal information but no color.
ply files can export color as well(you need to bake it to vertex first) but theres no build-in batch export for ply files in blender atm.
Then i import the obj sequence in TD for instancing.
If anyone wants to try this for yourself you can download a 60 frames version of the
obj sequence i created. link.
here is another obj sequence of an animated character for tryout.
this is another example with the same technique where i exported a rig from blender and mix it with a flex simulation in touchdesigner
it would be gr8 to be able to import the vdb files directly to touch. any chance this will be possible in the near future?
… i forgot to mute the sound in the first video before recording so… if you don´t like it mute it.
if you like it you can buy it here.
