logix1390 Posted July 14, 2018 Share Posted July 14, 2018 Hello, I am trying to make my particles avoid an object as they move along the Z direction. My object in this case is a sphere plugged into the second input. I have tried the pop axis force which technically works...however it becomes very hard to control when I add more forces to the particles like the pop wind. I tried the pop attract with negative values but the particles end up accelerating which is not what i want.... also tried the "pop steer obstacle". which is also very hard to control.. I feel like I am going down the wrong path here. Any tips will be greatly appreciated. I will attach my scene file for any one that wants to take a look. Thank you. avoid_object_pops.hip Quote Link to comment Share on other sites More sharing options...

logix1390 Posted July 15, 2018 Author Share Posted July 15, 2018 Thank you karanjaura, this is exactly the effect I needed. Works perfectly. But I am just wondering...is there an easier way to achieve something like this? I was assuming Houdini would have some built in tools to make particles avoid objects...Surely a beginner would not come up with a solution like in that video. Really appreciate the help!

Hi Mike, Glad it worked for you,I'm sure there must be other ways to accomplish the same effect and being a beginner myself too,I am also learning the tricks and trade of Houdini every single day and diving in Vops context feels scary at times Cheers !!

Can we convert them into to metaballs ? Quote Link to comment Share on other sites More sharing options...
