  1. Hi! I am currently working with H16.5 crowds and rendering in mantra, but when it comes to motionblur, the agents dont seem to have their own deformation blur, but only the velocity blur of the packed prims/pts. I attached a rendered image here, where you can see the problem. The wings flapping is pretty fast, so that should be visible in the MB actually. Is this not working in houdini for packed agents? Unpacking them to get actual geometry is not a solution for me now. Faking it with RSMB is also not an option since it generates bad results. Any ideas? Thanks a lot, Sebastian
  2. Hello! I'm stuggling with texturing my crowd. Random texturing for the agents themselves works fine, but I've added shapes which I can't adress in the stylesheet. It seems like I'm loosing my primitive group when adding the shape to the agent layer. So my question is: How to keep the shapes primitive group when adding to the agentlayer? Or am I missing something and there is another way of applying (random) textures on the added shapes?
  3. Hi everyone, Here's a weird one: I am trying to use the crowdsource to copy a simple agent animation on a point sim. It is basically a swarm test. Now the problem is that when I try to render my agents they render as boxes. So far I have done a couple days of research but I didn't seem to be able to find a solution or anybody with my same issue. The simple answer that I gave to myself was "use the copy sop with some timewarp stamping for each point" but the copy sop gets too heavy to quickly. Does anybody have an idea of what am I doing wrong? I have attached a zip file with the hip and the fbx of the bee animation. Thanks for your help! bees_test.zip
  4. Decided I'd learn how to work with the Houdini Crowd system by actually making my own agents from exported character animations out of World of Warcraft, but the main problem I've got is that since all of these clips started off without any locomotion, I need to figure out how you actually get that back in. Agent Edit SOP appears to work in the viewport at least...I can translate the character over the course of their walk cycle and reorient them (they start facing X instead of Z) but yet when I feed that into the Agent ROP it doesn't seem to stick. Not a ton of info out there sadly for working with custom Agents in H15.5, and even worse is that these particular FBX files explode if you try to Import -> FBX them which makes this all potentially a lot more difficult. Has to be loaded up via Agent SOP.
  5. Hello fellow Houdini users! I am using the Houdini Crowd setup. I am trying to trigger a state change in fish from a fast swim to a slow swim. I understand that using the triggers and transitions I can get animation clips to smoothly blend together over time. However I can't get the crowd steering nodes to transition together smoothly. Beneath my fast swim and slow swim states I have separate chains of crowd steer nodes, one that has low drag and high movement, and the other with high drag and low movement, and they then feed into the 'merge states' node and then into the crowdsolver. But when the transition is triggered there is no interpolation between these states, they immediately switch over regardless of the transition duration. Does anyone know a way I can get a smooth transition between two separate crowd steering states? Thank you for your help!
  6. Fishy Fish flock

    Hi there! My recent finished work where I used VEX to create fish flocking model. Difference from basic boid flocking model is that I made fishes to be aware of their front, right, left, etc and they turn towards their goal considering this. You can see it in Cohesion - fishes try to reach point in the middle of the screen. When point is behind they try to turn towards the point making circles, instead of just swimming backwards. Obstacle avoidance was done using sdf volume. After simulation was done I smoothed it a bit inside CHOP. Fish animation respect speed changes. Also fishes can bend depending on their velocity change. Rendered in Mantra, composed in Nuke.
