  1. Hey, Im trying to figure out how to create flip to have front of the simulation all the time splashy. I'm starting simulating from point A to point B and front of the simulation is pretty soft.. Ofcourse I can add some extra force at the begining where the emiter is but it will generate noise only near emitter but I would like to have noisy front of the simulation like on this simply attachment. Blue part repsresent this noise front of the simulation where I would like to have it all the time. I can try to create some volume with noise and animate it simillat to the river flow but I donkt think that this is the best idea for this. Any useful tips for this ?
  2. How exactly do you do the workflow for Flowmaps. I know there's the comb and obstacle nodes in the gameshelf, but if you wanted to copy a fluid simulation, would it be as simple as doing:0. Timeshift/freezeframe your fluid mesh1. Attribute transfer the velocity onto your flat river plane from your sculpted fluid sim. 2. Then with a wrangle, normalize the velocity attribute, then add the X/z values to the UVs? ie @uv += @velocity;I know people blend the uvs back and forth - one with rest one with the distorted UVs but not sure how to do that - I mean I know how to add the layer node to create a uv2, uv3 etc, but as far as importing into unreal, the extra uv sets created in Houdini don't translate over on my meshes only showing one UV set. For Vorticity/foam - I'm assuming you just make a vertex colored mask then blend/lerp to your content?
