  1. VDB velocity half circle?

    That is good to know. Thank you so much!
  2. VDB velocity half circle?

    Hi! Houdini beginner here. I have multiple curves that spin around that's being converted to VDB for smoke sim, but I'm getting this weird half-circle from its velocity. It almost looks like it's being clipped. How do I fix this? Thank you! vel_zero_on_z-axis.hipnc
  3. Smoke Sim- vel not coming through?

    Ohhh!!!!! Ahhh you are a life saver I was struggling for like hours x.x Thank you so much!
  4. Smoke Sim- vel not coming through?

    Hi! Here are the geo and the hip file (I deleted the custom temperature part to clean up the file). Thank you for a taking a look at it! rhinogeo.bgeo.sc smoke_sim_vel_mystery.hipnc
  5. Smoke Sim- vel not coming through?

    Hi! Houdini beginner here. I created a custom velocity using pointVOP and added onto VDB surface attrib point.v as vel. When I middle-mouse click, it shows that vel exists. I have it scaled higher than 0 on the volume source in the DOP network and set "Add" for the operation option, but it makes no difference in the smoke sim. There's supposed to be a noise pattern in the velocity, but it's only taking into account of gravity. If I disable the gravity, nothing happens to the volume (the volume surface get steppier? but it doesn't push the smoke or anything). There's also a custom temperature going into DOP, but that one works fine. So I think I missed a step somewhere when bringing the velocity into the DOP network.....What am I missing? Thank you!!
