Houdini Flip Mesh Flickers

Recommended Posts

Hello Everyone,
I was doing a flip sim and meshing it with vdb ,problems i m facing is
a) I am cutting down the bottom part with delete sop using bounding box,its getting hole at the top part, i dont know how to resolve it.
B) Mesh is getting too much of flicker.
c) Mesh coming out is too compact,how do i get the small details in splash.
d)is there any other awy to do a flip mesh in houdini with good details.

translate  your bounding box in -Y direction a little as it is also deleting primitives from top surface. Also u can increase the resolution in vbd to get more detailed mesh.

Play with erode and dilate settings in vdb reshape SDF node and with the vdb smoothing iterations. You can increase the resolution of the vdb and perhaps use a point replicate so the splash areas have more points to sample from.

Thanks Jenny and shachi , i will try these settings in my file.

One more question when i m making the mesh in vbd its coming too compact,i want to get  smaller details,is there any other way around to mesh the particles.

 

Thanks

Jenny, I'm really curious how you went about acheiving those beautiful inky splashes on your vimeo. I've had trouble getting those nice flaring shapes and stringy-ness in Houdini, coming to it from a realFlow background. I'd love to hear some tips, scene scale, pscale etc.
