Maybe your Box hast to much tesselation for shape match. Reduce it and attach the Higher Version with Point deform and Name Attribute Afterwards

There is lab thickness sop node. Once fracture, you can use that node for your thickness. From your question, I did a doodle FX transition from rigid to cloth

Thanks a Million.

I'd first extrude the geometry and then fracture it. For a useful extrusion I changed the normals and deleted one face at the toes. fracture.hiplc

Hi friends. I want to make destruction like this picture. but I have two problems. 1- I need thickness for the skin 2- when I use boolean fracture the pieces become filled. fracture.hip model.obj

given two points on the long edge of the rectangle, let's say they're point 0 and 1: vector p0 = point(0, "P", 0); vector p1 = point(0, "P", 1); vector n = normalize(p0 - p1); // compute matrix that rotates the normalized edge onto +X matrix3 d = dihedral(n, {1,0,0}); // transform points with this rotation @P *= d;

Hi, I’m currently working in Houdini and trying to rotate a non-perpendicular primitive to align it with the X-axis. In the second image, I used a Transform node and manually adjusted the rotation to achieve the alignment. Is there a procedural or more accurate way to achieve this? Any tips, improvements, or alternative approaches would be greatly appreciated. Thank you!

Trying to solve the same thing. Any updates?

copy to points

Hey, I have an aproach to solve the things above. I have a vornoi fractured geo and I need to transform the pieces by particle simulation. So all the pieces different. So the points would have orient attribute which will determine all the rotations of the pieces. I tried fransform pieces node but it's not working well for me.particleTransformsGeo_v01.001.hip How could it be easily solved ? Could it use pscale too ? Thanks in advance. G

The link is in my signature. As you can see, it's a problem with the "Edit" button. It never changes to "Save."

I think I solved the same issue by increasing the Dicing Quality Scale in Karma Render Settings.

Thanks!

Always good to check VEX cookbook https://www.sidefx.com/docs/houdini/vex/functions/snoise.html pos is @P*0.02 *you have two noises, second influences on first pos What you can do to play is ...snoise(((@P*0.02*ch("scaleA") +snoise(@P*0.02*ch("scaleB")...

Actually, do you have a link to that thread?

Hey Atom Sorry I missed this somehow... I'll look into it. edit: test.

Trying to reproduce this noise pattern from the MPM Advanced Avalanch example (left part of image circled in green) I think the issue might simple be one of scale. This is the vexpression @Cd = abs(float(snoise((@P*0.02+snoise(@P*0.02,5,0.5,1)),5,0.5,1))); What parameter should I be changing to get it working at a smaller scale for my head mesh?

rbd_constrain_multiple_anim_objects.mp4 constraint_multiple_anim_objects_to_rbd.hip maybe you can go from here ? i usually use the rigid solver

Solution For those who have the same problem: problem was in compiling vex snippets/scripts and you can fix it removing vex compiling directory. Example path : C:\Users\User\AppData\Local\Temp\houdini_temp\VEX_CodeCache

Hey, Guys! I have error with common Houdini vex based HDAs, like Attribute Blur: Preloaded shader is invalid. Houdini reinstallation didn't help( If dive inside we can see problem starts from "init_target_attribs" Any idea whats going on and how to fix it?

Hello, I'm trying to attach a box to my jacket, and I set it up as follows with a shape match for the box and a regular vellum setup that I combined, but I'm getting some strange results. Maybe there's another solution to attach this box to my jacket? Thanks!

Why not Imapct_RnD_v0004.hip

Hey - I See you included both .. thanks so much !

Seems like primnum is relative to source and impact points, you can transfer state by this. Imapct_RnD_v0003.hip

Hey Guys ... I'm messing with emitting RBDs .. I am using the SOP wrapper. Can anyone tell me how to change the color of my rbd when it impacts. ? I see there is an extract impacts button that gives me an object merge of impact points and I know there is an impact analysis node ... I have just never used this data so I am looking for advice. I have included a simple RnD scene to show the way I am emitting these ... based on a tutorial. appreciated Imapct_RnD_v0002.hip
