yeteatime Posted September 13, 2019 Share Posted September 13, 2019 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 Quote Link to comment Share on other sites More sharing options...
jinguang huang Posted September 14, 2019 Share Posted September 14, 2019 The top part is the viewport thing, visualization of "vel" volume. The density looks fine. And here is the vel volume If you want to see the correct velocity, you could use volume trail node to display the vel. vel_zero_on_z-axis.hipnc 1 Quote Link to comment Share on other sites More sharing options...
