Hi, I wonder if it is possible to trigger an animation on an event. Let's say I have a sphere, I simulate it falling on the ground just using a Dopnet and a ground plane as a static object. And let's say I want to play an animation each time the sphere touch the ground, like waves on some water. How can I do it ? I've heard of RBD Impact Analysis, but I can't find how to use the generated points for something like it ? Can someone help me ? And can I have an example file ? I link an example of wave that I want to trigger when the sphere touch the ground Sound_Wave_v001.hip

Hi. I am trying to implement a function that will set "on parameter" to false, and set "opacity parameter" to 0 on a Octane light node, when it's display flag is turned off. I would like to implement it in "pythonrc.py" or another similar structure, to keep it global, instead of implementing it into the light asset, but what event function can I use to get calls whenever display flags are changed?

Hello guys, I am doing my first post to see if anybody could guide me with this error. I updated Houdini to houdini 18 and an error started occuring everytime I open a proyect or pasated any node. It doesnt do anything, It just warns me of a unnrecognized token and it doesnt stop me from working, but it is really annoying. Could I have installed my license wrong? I find it hard to believe since I´ve been using Houdini since the 16th versionn and I can do it blindfolded now but who knows.

Hi, I have an HDA (sop) that contains a different HDA (rop). The problem I have is that I need both of them to run a OnCreated event, but it seems to run only when user creates the node, not when it gets created as a part of a different hda (both have the OnCreated working, when I just create them separatelly). Does anyone have a solution for this? Thanks Martin Running: Houdini 17.5, Linux

Hi everyone, The Montreal Houdini User Group is hosting an event next week! If you are from the area, please join us! It'll be a lot of fun. Event : https://www.facebook.com/events/1656260834658051/ MHUG : https://www.facebook.com/groups/montrealHUG

There are various event handlers you can use with HDA's (like onCreated, onInputChanged etc.) but I can't seem to find one that can be used as a callback for when the output connection of the HDA changes.. Basically i'm trying to create a custom version of the gas disturbance, part of which has the option to visualise the block size of the disturbance (just with coloured points on a grid). So I was thinking I would use an event handler on the HDA to know when it was connected and then in python traverse down the children to find the solver then traverse back up to find the smoke object so I can get the size and center to position the grid correctly. Is this possible? Is this a stupid idea?
