- A tutorial showing how to make procedural bricks or stones in Houdini using Voronoi fracture, A flexible and quick method that worked well for me and can be adjusted easily.
I hope it helps you! - Krátké a kreslené filmy
This was truly one of the most easiest and satisfying tutorials I have tried since I started learning Houdini. Thank you so very much. I was trying to figure out how you make the mortar between the bricks but I'm stumped.
Excellent! Clear, concise and packed with useful info. Thank you for putting this out - is very helpful
Wow this is amazing, right what I need for my demoreel.
I'm glad it was helpful :)
The result from following a tutorial is not demoreel material.
If only I found this video a few months ago...
Cool done ... But I would laid out the file with the project ... when they are browsed clearer to get
Can i start with an already curved fbx mesh made from maya and use its edges as point lines in houdini?
You should be able too, I'd have to try it to be sure but Houdini just needs the points to do its fracture, you wouldn't want anything too complex as you start creating something difficult to work with, I get more why you'd want to have the original surface from Maya as it can be hand crafted to fit a scene and create a line in Houdini to slice it up, that way you can adjust how it slices procedurally.
7:52 What is the Procedural solution to select every second row?
I'm still trying to find a good solution to be honest, I didn't science it enough, if the geometry is simple you can just create a simple wrangle to select every 2nd class ID that is generated from the connectivity node and that might work for you.
But in practice on a bigger project I find geo usually is far more complex for that too work since there are windows, and other holes in the base geo.
I've also used the vertical spline that is used for the fracture to just copy boxes and use that as a selection by bounding box on a group, that works but would need lots of points in the initial geo since it won't select faces this way. (You just need 1 point selected then you can group expand and promote to faces.)
If anyone has suggestions I'd love to try to find a good solution for this!
@@tomklejne3916 Thanks a lot! Great tutorial. 👍
I figured you can use an iteration number if (iteration%2==0) do sth different
Late reply, But for anyone still figuring this out:
I used 2 switchif's inside the loop with an prim("geo",0,"class",0)%2 expression
Using the true side of one and the false side of the other switchif you can split up the paths your geometry takes
And merge them back together in the loop aswell :)
