The first, if we just need a static volume it can be imported as a blinkscript or colorlookup node, this can be done through python... but its a bit nasty to do it like that. The other way is to convert the VDB file into a EXR sequence (each pixel representing a voxel), this can also be done directly from Houdini (creating a custom exr writer). In that way we can stream the voxels off the disk, cache it and all that, the down side being that you loose some of the many VDB benefits. The thrid way is offcause to make a C++ plugin to read the VDB directly, but that is cheating. But again it is not something i have spend too much time with yet, just tested it to confirm it works. So there might be other alternatives. On Fri, Aug 5, 2016 at 4:25 PM, Michael Garrett <[email protected]> wrote: > Fantastic!

I have made a blinkscript "Vox_ParticleToVox" that converts nuke particles into voxels. But it can also be used to turn a point position map into voxels. (the convertion process is essentially just taking the points and mapping them into the voxel grid map. > On 5 August 2016 at 05:48, Mike Wong | ax.gmail <[email protected]> > wrote: > >> Awesome !
