Hey everyone!

I've seen some old posts on this issue, but never found a solution.

I was wondering if anyone know if it's possible to clear all cache without having to close down Houdini.
The “Cache Manager” is only able to clear so much, and some cache is still left behind eventually causing Houdini to freeze. I'm currently working on a large terrain field, and I'm having to re-start Houdini after caching geometry to disk every so often.

If not, could I create a python script that will close and re-open houdini whenever I need to? Otherwise generating this terrain will become a very manual process, that I am sure I could automize.

Any help is much appreciated!

Hey Rob!

I have done some testing and yeah. I think I've been overcomplicating it.
Here is a test I did yesterday.

This is sourced used particles, but I'm going to do an RBD sim instead so I can get more variation in size, while having more interesting shapes. And then use particles to add more grains in some areas.

It's getting there, but still loads to do!

All the best,

Hey Diego!

Thanks for your reply! Would you have any tips on how I could get that “dissolving” look? That is why I've not tried RBD yet, as the chunks would be solid through the entire sequence. Unless I simulate the dissolving fx separately.

What I will try next is simulating RBD chunks, and then turning them into particles through a volume. Maybe I can do some cool dissolving effects like that.

Time to go back to the drawing board! Thanks for sharing your thoughts though.

If anyone have any cool tricks to cluster particles, so that they are nice chunks, throw me a bone. I've tried Pop Grains, but it's unnecessarily slow.

All the best!
