Magic Market | Procedural Rocks 1 | Geometry Generation

LESSON: www.sidefx.com/tutorials/magi...
In this part you will use various techniques to generate a high-resolution rock geometry. Thiswill require a plethora of VOP-based noises to add levels of detail to the rock. In between certain noises, you will learn how to clean up the geometry to avoid intersections and floating geometry.

you could use vdb segment by connectivity, and delete everything except segment 0, this node automaticolly sorts pieces from biggest to smallest

Thanks for all the amazing tutorials, you're a Godsend to us Noobs

You all prolly dont care at all but does someone know of a way to log back into an instagram account??
I was dumb forgot the login password. I would love any assistance you can offer me.

[@Misstigon]

it's so helpful and clear .Thanks

[@massimobaita7178]

Thank You very much!

[@3dpain378]

Thx, good lessons.

[@genetixa]

Thanks! However for the small_facets VOP , I would transfer the N from the sphere using an attribute transfer to smooth out the normal before displacement.

[@Godkiller08]

Could you explain why? (I'm a beginner at Houdini)

[@vishwakarma00]

The technique which you showed for extracting the large piece is good, but it can be done using single node called vdb segments by connectivity. It keeps the order based on largest pieces to smallest pieces, as it already has vdb data, that can be used.

[@quentintheret5106]

I'm quite new to houdini, but i remember that i saw that the connectivity node give the biggest element the first group, so you can just blast everything else, instead of doing the For each loop.

[@Moctop]

There is no guarantee of that with the regular connectivity node. "VDB segment by connectivity" however works like that.
There is also a SideFxLabs node "Delete small parts" though that can extract the largest piece.

If I start with a sphere then everything works fine, but if I import a piece of geo from Maya as either an fbx or abc, and the geo has less polys than the sphere, suddenly everything takes ages to cook or crashes. What is the best way to get geo into Houdini from another application for this kind of process?

[@calebollivant9789]

do a match size to your sphere. you're probably at a totally different scale & the convert to vdb & remesh nodes at the beginning are based on scene scale.

[@epicbattles3887]

it`s not doing the same thing for me for some reason

Nine between is that you?

thank you

[@Alex-pq4zl]

could anyone help a noob out and tell me how he is promoting parameters? I tried every kind of click, left / right, alt L / R, shift L/R clicking on every button on the screen and no luck....

[@izvarzone]

middle mouse

[@Alex-pq4zl]

@@izvarzone Ah thank you!! The one click I hadn't tried...

[@defonten]

Or, you can just model this kind of rocks in zbrush in like 2-3 minutes each, using alpha brushes with much (much) more control.

[@antiRuka]

noughty

[@mrpig4286]

lose too much detail when every time to intersection clean

[@YiChi457]

Really cool global tip ! but so much computational waste in the graph.

[@The_Deaf_Aussie]

oh.. its not Blender.. ok.. sorry to bother you.. i'll leave...
