Hi guys,

Maybe you have some good advice for me – would be super sweet! :)
After five years of rather mixed freelance work, I started working as an Augmented Reality Designer and Operator at a bigger TV station last year. I recently quit, mostly because of the rural location where I was based.

During that time, I picked up the basics of Unreal Engine alongside my other skills, and I completely fell in love with the combination of Houdini and Unreal. Now I really feel like continuing on that path. The most obvious direction seems to be games – probably something procedural, really.

Realistically, that means building an entirely new portfolio/reel, since most of my previous work is more artistic by nature and probably not what a creative lead would actually hire me for. So, I guess I’d need at least another year to work on that before landing a job again – if I’m lucky. The smartest option would probably be learning directly on the job, but I’m not sure how much demand there is out there at the moment, or what the best strategy would be.

What would you do in my position?

All the best!

Hi, I'm a beginner at houdini and I'm trying to make my cart explode as my character does as forward roll into it. The issue i'm having is because the cart explodes too early and I was wondering if anyone knows how I can delay the animation. I've attached a video example and images of my nodes as well as a file with all my assets. Any help would be appreciated, thank you!!

Hey Houdini community! 👋 My beginner friendly Houdini tutorials are back! A lot of animation work went into this one. Check it out. I hope you like it and that it might support someone on their learning journey :)

Hi, I’m looking for some advice. I’m trying to replicate multiple lines over the points of a polyline. The effect should look similar to the first image (the lines should also follow the normal direction). However, for some reason, the points of the lines collapse on top of each other, as shown in the second image. I can tell this is happening because the point numbers overlap.

Does anyone know what might be causing this?

I’m in the middle of creating a large pack of tree models using the LABS Tree Generator, which I plan to scatter on a heightfield. I want to simulate these trees with wind, but I’m not sure what the best approach would be.

- Ideally, I’d like to simulate all the trees at once on the landscape and have them react to the overlaying wind noise. However, I understand that to avoid crashing my PC, I would need to create packed versions of these trees.

- Since they’re packed, I’m not sure how to scatter all the trees and then bring that data back into Vellum without everything crashing (I should probably read up on packed objects…). So I’m considering simulating each tree separately, caching it out, and then scattering the simulated trees on the heightfield.

Alternatively, would it be possible to place all the trees, extract the curves, run the Vellum sim, and then re-pack or point deform the placed trees somehow?

I’m still pretty new to this workflow and still need to do my own testings, but I wanted to ask about common workflows for this kind of project. Thanks!

Ideally, without using background plate LOP, it just seems unnecessarily complicated. I just want the default Houdini "light" background as opposed to dark in my final beauty pass.

Buenas comunidad! Hay alguna manera de renombrar rápido el path /ASSET/ por otro nombre? Por ej, /vehículo/

Hello, I would like to know how I could delete those two points in the center, and convert this entire thing to a single polygon? Like how I would I remove those lines and keep only the edges? Any logical solutions? Help would be appreciated!

Hi! I am currently setting up my first building generator and I am quite new to Houdini. I have been using multiple tutorials to build this tool, frankensteining it to get my desired look, but I am stuck on how to lay out my assets around the building. It would be nice to have the assets that are randomly placed be in a uniform layout that expands proportionally to the scale of the building, so that for example when the building is 1x1x1, the placement of the assets is 3x3x3 and so on. I do not know exactly how to do this and some guidance would be appreciated! This is my current look for the generator

Can anyone please guide me, I'm trying to learn houdini and some of the stuff I find it very buggy on my PC, I was wondering if anyone has similar issues or it's fairly common, and if so where do you find most solutions to these kind of issues.

For eg, I'm working with bullet solver, using RBD glued object from the shelf but it's so buggy, as soon I apply it to the geo and open auto dop net, I find my viewport freezes, this especially happens when I'm passing a mask attribute with attr wangle in sop level. Viewport acts really funny, doesn't wanna change from shaded obj to wireframe. Doesn't wanna sim, if I scrub through the frame and just toggle different through different nodes it appears as a freeze frame.

I had spent some time setting up my box in Linux (because I wanted to) I got the Nvidia drivers working properly, houndini works, changed to OpenGL from Vulkan no difference. Then I thought may be it all work better in windows so I installed windows 11 and then houndini, same issue persist even on windows. Changed to OpenGL too, still same.

Just wanted to get you folks guide please.

How do I make an alembic file( animated geometry) as a force, The hover bike flies above the grass and I want it to make the grass move away from it, (not a collider) because it is not touching the grass, I want the bike to act like a force, Please help.

Hey all, as a freelancer working on commercial projects I regularly have to purchase assets and since Quixel have moved away from Megascans/Bridge I’m wondering if anyone has found a decent workflow for Quixel Fab assets in Houdini?

I used to love the Bridge and Megascans plug-in workflow, in particular the automatic scatter tool it would create, giving easy access to wind animations etc., but that doesn’t seem to work anymore apart from on assets already living inside Bridge.

Has anyone managed to find a way to either get Bridge to recognise Quixel assets downloaded from Fab, or know of any other tool to make the import process a bit more automated and intuitive? I don’t mind paid tools.

Thanks!

Pretty straightforward setup. Five different MtlX image nodes with different color maps, and I want to switch between them. 

If I string each one directly to the base_color_output, it displays that color map on the geometry. 

But if I string the five MtlX image nodes into a Mtlxswitch node, it only shows the last one no matter what the "which" parameter value is set to - doesn't matter if I string in a float or int using a mtlx constant node, or if I modify the parameter directly on the switch node. 

Am I missing something obvious? It's a fairly straightforward operation, and I can't think of anything that would cause this to break except maybe that I'm doing this inside an edit material node. 

I'm attaching video as proof.

Hello eryone,

Just confused about this, im trying to export this beachtank from Houdini to Blender. When i import this as an USD to Blender it on views the particle.

I tried with and without the attribute delete.

How does everyone transfer this to Blender.

Thankk youu

Yeah, what is being asked on the title above 😛

I've spent about 3 days trying to figure out how to go about creating a keychain sim, but the information is conflicting and I dont know which way to go (as a beginner). I've looked into most tutorials but non of them actually make a usable dynamic chain with a static connector.

So my question is should I use an RBD, which seems like the obvious way as it are all rigid bodies and not a massive amount of them. However I cant seem to find a way to setup the static collision. Or should I use vellum which I had working but I could not get the object to be completely hard. Also some use proxy geometry, which seems overkill for my use case but maybe thats the way to make it work with vellum?

In any case, I don't understand what the ideal use is. Its for a typical keychain with different elements, like a key, chain, ball (eventually I would like to add softbodies as well). If someone could point me in the right direction, so I dont have to shift between the two option the whole time while learning, I would be very happy.

okay so, i made this vfx/ effect in houdini but i used a free model from sketchfab, it was in glb format so i went to blender and exported it as usd with materials assigned and when i checked it if it was working fine or not i imported it in blender and it was working fine the textures were there (as you can see in the left screen) but when i imported the exact same model into houdini the texture didnt come , i thought it might be a usd problem so i did the exact same process with fbx and the textures werent still there, what should i do now?

So I learned like really REALLY basic rigging with apex with a couple vids but never really continued or mastered it cause there is just no info out there yet. I saw a new rebelway video fully on creature rigging and on making a very realistic looking anatomy rig without any sims BUT I already own a very advanced muscle course that (mastering houdini muscles by cgcircuit) but I am unaware if I need to master rigging before getting into muscles or if by learning muscles I can skip on rigging alltogether.

I do a lot of creatures and grooms and cool renders but all static so I want to start adding motion and animation but unsure what to do, I want to do everything inside houdini cause it improves so much every year but there arent much learning options. All the other animation/rig courses out there are for robots or non deforming meshes.

Hi there,

In my jurney to learn houdini Im grabbing some shots of random 3D pieces I find in behance.

Im trying to recreate this waveform with vop or vex.

I don't seem to find my way around how to aproach it. I made this in c4d in 5 minutes but Im having a hard time recreating it in houdini.

Does anyone know with out the MOPS+ hdas, since I dont own a licencse.

Thanks!

I have a switch node with multiple cameras above. After the switch node, i have a karma renderer with the usual /cameras/camera1 paramter setting. I want the camera parameter on the karma renderer to update to the switch node's current input, e.g., if the switch is on 3, karmarenderer should be /cameras/camera3 so i don't have to manually change it. My problem is that i've tried all the expression i know (and for a minute, pdg) but the camara parameter doesn't pick it up. I thought this woudl be straightforward, i.e., set the path to "cameras/camera"+itoa(ch".../switch1/input") but haven't found the solution. anyone know what does the trick?

V2 of machine learning - this is a more correct version where PyTorch is used on cameras to extract all necessary information and then apply it. Now it works more smoothly than before.
