trzanko posted a topic in General Houdini QuestionsHello,I'm attempting to create the slitscan/timeshift effect. I'm creating a vector array in a for loop, each loop has an attrib from map and a wrangle that appends Cd to a vector array. It works when the attrib from map is always reading from the same file. When I change the attrib from map file read expression to anything that has to do with $F or the meta nodes iteration Houdini crashes. I have a test scene that has documentation and even nodes setup to create test frames to work with.If it is a matter of the way that multiple files cannot be read at once please let me know. If someone knows of a better way to read from multiple files at once and/or achieve this effect please let me know. I'm aware that after effects has this effect and uses gradients to determine which frame to look up color from. While that method is great, I'd like to be able to write the gradients/lookups in vex to achieve results. Any help greatly appreciated. -T concept_025_slitScan_v001.hiplc

Hi, recently I watched this breakdown. I am not sure that I understood how author did collisions with fluids. It seems to me like he generated motion vectors in compositing application (Nuke's vector generator?) and then somehow transferred it to houdini where he generated velocity field based on those vectors? But I don't understand how one can transfer 2D motion data from one camera to 3D. It isn't possible, is it? I'd say that for such collisions proxy geometry must be animated. Like in this video (1:00) Do you have experience with integrating real footage collisions with fluid sims? Are there any workflows that can speed up this process? Thanks, Juraj
