@dedeks2999 Thanks. Works as expected. Just wondering how do I do it within a node so it would be procedural.

Hi, Is it possible to select/group only "vertical" edges as opposed to "horizontal" edges? You can see below marked by red marker of what I refer to as vertical. Illustration file: circular.fbx

Can't tell how to model vegetables procedurally. But if you want slice, there is a procedural slicing in labs tool. Namely, Labs Polyslice and Labs MeshSlice

The script above relies on the selection node. as you can see below, H19 no longer uses the selection node (i..e it does not appear in the parameter). By any chance, any one knows the H19 equivalent of selection node?

Hi, While selecting Guide Groom Node in 18.5, executing the code below gives me a value. node.parm('selectionnode') But when I execute that in 19. It gives me a None. This breaks the whole script. So I was wondering if there are any API changes in 19 that I should use instead of the 'selectionnode' P.S. For reference, I'm trying to make this script Houdini 19 compatible.

Hi @pighead, How about assigning materials before the vellum nodes?

Hi, How do I merge 3 different edge groups in Polybridge? If there is only 2, it works. If there is 3, the other is not accounted for. In essence, I just want to dynamically fill some face in between the spaces. I also tried polyfill but it will only fill the spaces on the plane (i.e not taking into account the sphere) You can see an illustration of the problem below: dynamically_fill.mp4 dynamic_polybridge.hipnc

Hi, In this documentation, there is a phrase of The Vellum Constraints node now has options to adjust the size of the cloth automatically. I'm using H19, same as the documentation, but I don't see such options in my vellum constraints. Is there a way to make it visible?

RE: I only know where it needs to be active, i.e as some information in SOP. I mean you can just place a bounding box or any geometry where it needs to be active and maybe attribute transfer from @active=0 to @active=1?

Uhm. How about animating the @active attribute? @active=0 means no simulation while @active=1 means the simulation will take over.

Hi @doc Thanks for the file! it works as expected. Didn't know there was a handy use case for Object Merge's Transform Into Specified Object option

Hi, I have a bunch of cards scattered on a geo. They are oriented to always face the camera. But is it possible for them to also use the mesh's normal to have a more natural rotation AND still face the camera. You can check the image below for illustration. modified_aim_constraint.hipnc

Hi @Librarian @konstantin magnus Thank you for reply! And yes, the illustration file on your website works as expected. That was indeed a nice problem solving method (i.e. using UV to displace two different objects). Have a great day ahead!

Hi, By default, heightfield erode node is only applicable on heighfield data. I'm wondering if its possible to use it on a regular polygon mesh? I want to use a heavily modified mesh (i.e. logo, hero asset) and erode it.

Thanks for the responses. @Librarian I couldn't quite directly use it since I guess the code is for the mat context. That said I think I get the overall logic. I think its doing Method #2 in the code below. @animatrix The code works as expected. ========== Also just for reference. People from slack group also helped me. Here are the results. Same goal just different execution. Method 1 (from bcarmeli) vector @cdir; vector @raydir; matrix camMatrix = optransform(chs("camera")); //get a matrix with the camera's transforms. @cdir = cracktransform(0, 0, 0, {0,0,0}, camMatrix); //extract out the camera position as a vector @raydir = normalize(@P-@cdir); //get a vector to project pointo from camera f@facing_ratio = fit11(dot(@N, @raydir),0,1); if(@facing_ratio>chf("threshold")){ @group_mygroup = 1; } Method 2 (from David Torno) vector cam = getpointbbox_center(1); //Option 1: Get dir per point vector dir = normalize(@P - cam); //Option 2: Get single point centroid //vector c = getpointbbox_center(0); //vector dir = normalize(@P - c); float d = fit11(dot(@N, dir), 0, 1); if(d > chf("threshold"))i@group_mygroup =1; Will close this thread now. Thanks for the help!
