This is super helpful man, super helpful. Thank. You for making this.

Great tutorial! Had no idea about saving presets either so this helped a ton

That was such a great, precise and straight to the point tutorial! Thank you, great work : )

thank you very much, very kind Sir, and thank you in particular for creating the second part, since I had problems with the first but succeeded with the second method.

thanks for sharing such an informative tutorial!

Awesome tip and technique. Especially with the alternate methods. Im moving over to Houdini and this was great to learn. Thanks

Thanks! Just what I needed.

This is great to know. Thanks!

Awesome tutorial, i love your teaching style cause you always make complicated stuff easy to understand. I bought some of your udemy courses, but please permit make a future course request there are extreme shortage of clearly explained tutorials on how to build a realistic third person character controller system with great camera and weapon management system like the TPS controller system in the last of us. Please think of it.

So very useful. Thanks

Really well explained and concise, cross product can become overly complicated to wrap your mind around but you've managed to really make it clear and easy. Thank you!! Hopefully can manage something similar for quaternions : )

this solved my problem Thanks a lot

Thanks a lot, I always use polyframe node after the resample to get the tangent attribute into normals but never noticed it exist inside the resample node

thanks a lot, really appreciate it

way to go man

great tut that helped me discover my problem.... the resample node is creating some wonky normals on my noisy curve that's mainly vertical, but they're much cleaner if I first rotate my curve -90 on the x axis. any ideas on how to get the cleaner normals without rotating it?

Brilliant, thank you ! When are you going to show the Rollercoaster-Generator ? :)

degenrate case occurs when tangential vector is vertical, which leads to totally opposite flatnorm bwtween adjacent points

Thank you

Hello! Very nice tutorial. This works well with open curve. I tried it on 2 closed curves. First one created in a counter clock direction. Second one in a clockwise direction. I have a Sweep node at the end but only the first curve red normal point inward. How would it be possible to use any type of curve red normal to always point inward? Thank you in advance for you help and keep on doing such great tutorials :)

Thank you so much for the video! I was having a lot of trouble with my geo not following the normals the way I thought it should, this solved it all :) one thing I do not understand, is that we create the flat, right and up parameters.. but how does the sweep node know that those are referring to the proper normal direction if those are "made up" parameters?

very good tutoria🤣, i am wondering the curve vertex if is possible add width for each point and edit it on houdini engine? I only know it can you gradient node to do it but its not really what I like

So, I've run into a bit of a snag. I'm trying to push points along their right and up vectors randomly. To simplify lets forget about the randomization, if I try and do, @P = @P + @right*ch("scalar");, the points just don't go in the correct direction, like I'm looking right at the values in the viewport and the movement just isn't correct at all. If I pull up the geometry spreadsheet, my right vector is expressed in terms of right[0], right[1], right[3]. Now if I look at the up vector, for some reason its components are actually expressed in terms of x y and z, and this simple vex code works properly when tested with the up vector, it's able to push them along that up vector in a way that's expected. So my only guess is when adding two vectors, where one (@P) has its components expressed as xyz and another (@right) whose components are 0 1 2, its like it doesn't know how to "match them up" or something. So, when I define a custom vector attribute, how do I make sure that its components are gonna be expressed as x y z?

Thanks! Is it better than "orientalongcurve" node?

Hi, why did you flatten the normals in the Y direction? Is there any reason I should use flattened normals instead of the original ones in the cross product? Thanks.

Hey, I tried your method and compare with just simpe a single line @up= {0,1,0}; I see no different in the sweep or copy to points? What wrong here?

doesnt the direction of flattened normal flip when you do full rotation track? like loop track?

Houdini wont let me start the creation of the curve once the component is there, but I heard a click on your keyboard/mouse. Would be lovely to let me know what key mouse/keyboard you clicked to do that

I have a problem, when I put the subdivision curve nothing happens, it does not smooth.

Why not just use a polyframe node? It does all this for you. Don't get me wrong - understanding the cross product is super helpful, but for curves polyframe is quick and easy.

yeah this tutorial is broken! I don't think this method is working in Houdini 20. All I get is errors and weird situations where nothing is actually happening in the viewport.
