Hey everyone! I recently finished up a tutorial on creating game ready procedural rocks assets for UE4 Hopefully you can learn a thing or two on my process and feel free to let me know if you have any suggestions, critique, or questions about anything you see!

Wenye posted a topic in EffectsI'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.
