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.

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

Very nice! Looks really good, you did a great job with this.

For improving it even more you could add some sort of microdisplacement like in this example [hasenjager.cgsociety.org]. Update us if you make some more progress

Hi, I'm new to Houdini shading, may I ask how to make those shiny white points ? I used your tips on frequency on roughness, but it left me no specular but only surface displacement. It would be great if you could share some ideas of how to make white points. Thank you!

Here is a quick example on how to create some flakes/shiny points. Is basically just adding an extra layer of reflection on top of the main material and multiplying an high frequency noise.
Another way would be to adding a noise to the normals of the surface at rendering time
