Hi guys,

I like to import particles from another application and apply some additional work in Lightwave. I've been out of the loop for a while and not sure which file format works best? Does lightwave alembic support particles? There's also FBX, Collada, or mdds? maybe I should export the particles with small sphere geometries? Not sure how to best go about this. Any insight would be appreciated. thanks.

Crook over at Foundation 3D says he'w working on a method to get Blender Particles into Lightwave. The results look good so far.

That looks awesome for Blender, but I'm actually trying to find a solution to get Modo particles into LW.

I know I found a youtube video a while back about transfer particles from blender to modo using mdd. That workflow should work from modo to LW as well. Search on youtube...

Ok, MDD didn't work. Actually, the only way to get particles out of Modo is to use Alembic support of Particles. I have to see if LW 2018 support importing that.

it would be great, since that also would support Houdini particles

I made TrueArt's Node Library http://nodelibrary.trueart.eu
CSV Reader node,
which can read any .csv file..

So if you will generate such file from 3rd party app (make custom script), you can get it in LW using this node..

Oliver Hotz has a pfx to alembic converter. I'm not sure if he ever released it as part of his OD tools but you can drop him a line to see if he would be interested in distributing it. With it I'm able to export my particles from Modo into any app that imports Alembic.

Great converter, especially if you are doing Houdini work and back to LightWave. It's a bonus download among others when you get ODTools set, Windows Only.

sounds good, heard the converter had a particle limitation? anyone knows if it got fixed?

64bit has none, pfx could have

Oliver Hotz:
not the 64 bit version
i THINK pfx has a limit though.. but i dont remember
however.. transferring a couple million particles.. you'd be VERY VERY sorry in lw

Why is it Windows-only? What dependency drives that limitation?

availability of compiled alembic modules for osX.. and to be honest.. because it is a NIGHTMARE to do this stuff on the mac.. thats why.

I've been using VDB for blender smoke. If you can export in VDB format it may work for you. In LW2018 there's an openvdb node you can use.

Ok, I found another way to export out the particles with small cubes attached to them and baked to alembic. This should work and allow me to mess around with TFD in LW.141994
