baroba Posted June 16, 2018 Share Posted June 16, 2018 Hi all, I am completely new to Houdini, I knew what it is capable of but I have no idea how to start my little project. A few guys at work need a lot of damaged containers and they asked me if I knew of a method to make them procedurally. I thought of Houdini, ofcourse. I have 3d models of containers, but no idea how to start damaging container, I would guess some cloth-fx set to simulate metal? And then make some random( procedural) shapes to collide with the containers? Or is there a better method? Let me know to do to this, thanks in advance.

Yon Posted June 16, 2018 Share Posted June 16, 2018 (edited) You do not need a simulated solution, also if there are 1000 containers that would be a poor choice. Make a mask that isolates damaged area. For example a scattered point + attribute transfer and attribute blur for a falloff. Then displace point position by inverse normal + noise * that mask. If your new this may be unfamiliar though.. Edited June 16, 2018 by Yon Quote Link to comment Share on other sites More sharing options...
Yon Posted June 17, 2018 Share Posted June 17, 2018 to automate this over x containers is outside the scope of this but look into using a wedge rop, it is not hard this doesn't support collisions as it is procedural, if your really tasked with collisions on 1000 containers with external anim that is a big effect and not a easy to avoid the cost. but it can be done with spring to glue constraints and point deform. A cheap sops collisions could be multiplying invertnormal you will find by distance to collision object. Damage.hip Quote Link to comment Share on other sites More sharing options...
baroba Posted June 24, 2018 Author Share Posted June 24, 2018 Thanks a lot James. I will have to study to find out how you did this but I think it pretty much what I want. I also think a full simulation would be too much, but if you can fake it I just need 1000's of containers, but each one with different damage. No need for a animation with 1000's of containers. Just 1000's of sideviews showing damage. ( I work in a crazy business ) I will let you know how it went ( could take a while) Cheers and thanks again, Rob Quote Link to comment Share on other sites More sharing options...
