Kim Davidson is pretty cool.

I’d really appreciate some honest feedback on the lighting, materials, animation, camera movement, compositing, and overall realism/premium feel.

What would you improve to make this look more like a professional commercial?

Any criticism is welcome — I’m mainly posting this to learn and improve.

Hello!
here's a new tutorial that I'm sure will be useful to many:

Ever wonder how to cook up your own procedurally modeled Krabby Patty? Well, look no further! Starring Robert Moore, this burger breakdown dives into procedural modeling with vex, lettuce solvers, vellum layout, and much more.

Part 1 is down to earth with the basic setup / overview, and part II is when things start to sizzle with move advanced topics. This was produced as a bonus section for CG Forge's modeling II course, (which revolves around procedural modeling), and over there you can download the scene files as part of the course if you'd like.

Cheers! 🍔

The MPM surface node has a second input for surface and vel, and the tooltip IDs it as:

MPM Surface and Vel
The output of the MPM Surface. Useful to split the SDF creation from the polygon mesh creation in two separate steps.

What is the advantage of splitting the operation up into two steps? So I can perform operations on the SDF first, and then feed that into the polygon surface operation?

A personal 3D project exploring vellum simulations and COP texturing Rendered with Karma

I am trying to make a test render to help assist my lookdev, but for some reason my node set up wont let me output an image in a readable format, only EXR. i have attached screenshots for anyone who is interested in helping me out.

note: i have tried editing the path and renaming it from exr to jpg/png but doing this makes the render fail, and does not output an image in the specified directory.

I'm just writing to vent. I'm so frustrated with the way Houdini is making the Cop Network - Old hard to create. In 21, it was still there. In 22, all I can do is open a file created on an older version to copy paste the node into the new Houdini.

I'm a big user of the old cop network. I hate Copernicus. Everything I could do with the old cop network takes 2 to 5 times more nodes and setup in Copernicus and now every AI search result confuses both of them and keeps giving half assed answers that lead nowhere.

Why is there no "Level" node in Copernicus? Just fuckin WHY????

Or Mosaic for that matter. I work in video games and mosaic is such a huge time saver for assembling sprite sheets and the new equivalent that is named "Contact Sheet" can only work if I separately load all images as separate file nodes instead of a single sequence.

Why the fuck is this trash being force fed down my throat goddamnit!

I think that it is very unfortunate that Houdini does not support the metal api. Macs have gotten to the point that they rival high end nvidia gpus and have significantly more vram (and I am pretty sure the most vram you can buy on an individual chip from any manufacturer). If SideFX added metal support to karma, the mpm solver, the vellum solver, copernicus, the flip solver, and the pyro solver, Macs would be a no-brainer for many artists.

That being said, are there any plans to introduce this support in the near future?

hey guys, i've been working on my first waterfall sim in houdini, and i've kinda hit a wall with figuring out how to mesh it and to get the smooth transition between the water and the foam. Trying to kill points based on vorticity, speed or Foam density attribute all seem to not work out for me. also this is my first time using Karma render and i kinda dont know the workflow for the whitewater stuff. If someone could just give an idea on how to actually mesh it and set up materials for the vdbs and attributes. Idk if i can post HIP file but i'll just leave the preview of the sim here couse i dont even know if the main sim setup looks fine (part sep 0.05 voxel 0.1) and a screenshot of karma preview with the water as vdb with whitewater material

I have a very simple flip using a tank with a animated object that rise through the water. If I view from the flip solver it respects the collision but after 'Fluid Compress' it is completely ignored.

Is this common and are there any work arounds?

hello guys after rendering just the ocean to check , I realized the waves and choppines are off, this is my first project ,trying it without checking course or tutorials.

I'm going for middly stormy sea and now I feel the waves are off , they are bit small and too choppy right ?

I'm wondering if it's possible to redo the ocean spectrum without redoing the sim ? the sim itself has an rbd boat that was simulated for movement with very rough flip(that uses the ocean spectrum for the big movement) , before the main flip sim.

or can I lower the displacement in the shader ?

Thanks

Hii I'm a beginner using Houdini and Maya. I tried rigged and animated a character in Maya, and the mesh looks fine there, but when I import it as FBX into Houdini, it's broken (pics on the right). What could be causing this?

My understanding of for loops is just too weak. I know it can be done, but can't figure it out. I'm trying to do a system that I can chose the amount of points my cutter moves for my wood lathe, and also rotate my piece of wood off-axis a certain amount each time my cutter cuts at one position (which makes a spiral) I did a version where I do it twice, but I want to do 30+ times. Just can't wrap my head around feedback loops etc. Could someone enlighten me? Thanks!

usually i would do this with rbd + vellum, but i wanted to try it with mpm instead. not the same amount of control and it needs a lot of clean up, but overall i think you can get a realistic and more natural look.

Hey everyone,

Working on a procedural pave solver and ran into an issue with stones on tighter curves.

Even when collision checks pass, bigger stones near surface edges end up with their outer girdles sticking out too far because of the local curvature.

To fix this, I added a local curvature/gap check during distribution. If the distance between the stone’s edge and the surface exceeds a set tolerance (around 0.015mm), the solver automatically downsizes that stone to the next standard size in 0.05mm steps until it sits properly and relaxing accordingly .

Seems to work pretty clean so far for keeping topology consistent on sharp turns.

Curious how others handle dynamic clearance or edge alignment on curved surfaces in Houdini?

Hey guys, I wanted to ask if it's possible to create aesthetic lighting and really cool-looking renders in Houdini.

I'm mainly learning Houdini for FX, but I also want to create some cinematic and visually appealing renders. Should I focus on lighting in Houdini itself, or would it be better to learn lighting in Maya or Blender?

Also, how much knowledge of Nuke and DaVinci Resolve should I have to make my renders look more professional? Do I need to learn compositing and color grading in depth, or is basic knowledge enough?

Would love to hear your suggestions!

Hey again :-)

After many months of polishing, adding new features and cleaning up my graph, I decided to put my Jackfruit project file on G*mroad for everyone to explore and tinker with on their own leisure. If you’re interested, follow my linktree on my profile. Thanks <3

Hey guys,

I have been doing XGen and I’m very interested in exploring the Houdini Hair and Fur system.

I posted a similar post a month ago and I went through some of the recommended free tutorials and they were great.

I’m looking for a high quality paid tutorials (nothing too expensive as I can’t afford much) that includes the assets so we can follow the tutorials. Gnomon was a great resource but some of them didn’t have assets included and it felt a bit limiting as I could not practice.

I hope it’s not against the rules but if it is, please feel free to let me know and I will delete the post.

Thanks!
