Hi, so I'm following some tutorials from sidefx and I was just wondering if it's possible to use a volume with volume from attribute SOP (transfering point normals to volume) to drive a fluid simulation? I used the volcano tutorial from sidefx's vimeo page as a guide. That means, I used Source Volume with volumeSOP (with points normals). But the problem I'm having is the simulation is different from this Source VolumeDOP.

The volumeTrailSop shows different direction. The input I was using in volumeVOP is Position then output to parameter named vel.

I have used the same volume with point normals to drive a popnet sim and it worked.

So basically, I have a volume with points normal attributes transferred using volumeFromAttributeSOP. I want to use that to direct my smoke sim.

I appreciate any help thank you.
