Hey guys, so I'm building a procedural erode / rock tool. Here are my results so far, the tool generates an infinite number of variations on these. I intend to add more surface detail like cracks and more small geometry details, breaking up the edges more, tweaking the nodes and playing around with it. I'm very happy with the results so far. Also I'd like to know if people are interested in this, it feels nice working on this knowing that it will be useful for people. All the best, Wout

Hello Houdinians First i just want to say how precious is all the help and tutorials that all of you guys have provided, this is very generous of you and your talent! Now that i have used flattery... (lol) I have been using houdini for about 18 months, and i still have a steep learning curve ahead to learn VEX coding and expressions, but i am slowly understanding the basic principles... I need to replicate an ancient building technique, and i need to create some variable size rocks falling from an emitter and filling-up a container or structure, piling up to fill the structure. (about 1000 rocks , between 20cm and 40cm, filling a 4m x 4m x4m box ) I found some tutorials relating to instancing or copy/stamp techniques, but some are from older versions of houdini and i have difficulty achieving this . i manage to obtain a popnet liberating particles to which i instanced a sphere (rock) , but cannot get them as RBD to pile-up correctly. I there an easy way using the shelf tools, or information you could help me find to help me build this rather simple simulation ? thank you for any help, and have a great day! Pierre D.

Lazy, but I wanted to get a lot of rocks. I fractured a box, this is the exploded view, how do I save the individual rocks as obj?

I'm trying to imitate the motion of rocks falling on dirt. Since the RBD Solver seems to give me more accurate and realistic looking results over the Bullet Solver, I decided to go with that method using RBD Fractured Object. When I first had my scene setup with Bullet, I was able to use a little VEX in the SOP Solve to artificially reduce velocities as rocks fell below a certain Y value. It seems like that setup isn't compatible with my RBD setup, so I was wondering what would I need to do to get it working? In addition, how can I write an expression that would tell the solver to reduce the velocities of the objects by half and double their weight each time they impact the ground? Any tips would be greatly appreciated. Thank you! RBDTest_001.hiplc

I take a sphere and then apply the mountain SOP to this sphere. Then I add a Copy node which is fed a point cloud from a sphere, IsoOfset, and scatter combination. Below the Copy I place a NULL node. In this Null Node I can see the total number of packed Primitives. What I would like to do is to be able to modify the Frequency Parameter on the Mountain Sop for each of the Primitives that are being Copied so that each one of the Primitives has a unique shape. I need a variety of moon rock to blast out. Without modifying them, they all look the same. Any thoughts on how I can accomplish the ability to dynamically create rocks of various shapes. Thanks in advance.
