Distribute points (randomly) in a mesh with an increase in density towards the center (Points from Volume) Jan. 31, 2020, 9:03 a.m.

Maybe you can first scatter billions of points in your volume.
After that you sample your density to the points and delete a percentage of it based on the density. For example if the density is one you are going to keep all the points inside the voxel, if the density is 0.1 you keep just the 10% (you can do it by give to the point a random number and compare it to the desired percentage, but I think you already know how to do it )

Ground Plane missing? Oct. 30, 2019, 5:54 a.m.

Hello!

Agree with the user above. Houdini changed a lot in the past versions and there are a lot of more recent tutorials for destruction.

As far as I remember there are no specific tutorials about this kind of effect but a couple of examples are:

https://www.youtube.com/watch?v=YocC2s6vdvg [www.youtube.com] -> this is more a brute force approach I guess. The geometry of the snakes are pushing and moving the pieces of the fractured ground. If you keep the root below the ground layer you can push the pieces up using the root's collision geometry

https://vimeo.com/154281290 [vimeo.com] -> Here the curves are activating rigid bodies pieces and probably assigning and initial velocity. This method maybe is a bit more advanced but would be more easy to get the result you want. Of course you can make the radius bigger and have stronger velocities if you need.

Houdini 18 release date? Oct. 28, 2019, 10:59 a.m.

Would be cool! It was a lot of fun to watch the Solaris reveal live with some other Houdini people
