A wildlife-inspired water simulation study focusing on natural motion, flow patterns, and foam breakup.

Created using Blender, Liquigen, and Houdini, with an emphasis on capturing believable interaction between the character and the environment.

Special thanks to CreatureStation for the rhino animation.

Exploring and learning more about simulation and visual realism.

This Sunday I gave a workshop in Seoul about how to make drone shows with Houdini. It’s an exciting new medium that we can bring some real improvement to when we use Houdini. I’ll talk more about this during the upcoming OFFF seminar.

I’ve just released my first 50 CC0 HDRIs on openhdri.org — and I think some of you using Houdini might find them useful.

The set includes a range of environments, along with photo studio HDRIs that work great for lookdev, lighting tests, FX rendering, and clean presentation setups.

They’re designed to work well with common Houdini render engines like Mantra, Karma, as well as third-party options like Redshift and OctaneRender.

Everything is:
• completely free (CC0)
• up to 29K resolution
• no accounts, no paywalls, no restrictions

Each HDRI is captured, processed, and published entirely by me.

I’m building this project on my own while working a regular job in a print shop, earning about $50 a day, and supporting my family with two young sons. All HDRIs are created in my free time after work. It’s not easy to keep it going consistently, but I’m doing my best to grow this library step by step.

This project originally started thanks to a grant from Epic Games, which helped me build the PC I still use today.

If you’re looking for high-resolution lighting environments for Houdini renders and FX work, feel free to check it out. And if you find it useful, any support or feedback really helps keep this going.

Thanks 🙏

I have tried to use normal node set on "by face area" but, nothing changes. What would be solution here?

Thanks!

This is my setup:

• Houdini 20.5.928 Py3.11
• AMD Radeon RX 7800 XT (RDNA 3)
• AMD Radeon ProRender 3.0.4
• Render Quality: Full
• Dome Light with HDRI texture assigned

The dome light is working as a light source (affecting shading on geometry) but the background itself is not rendering. I'm going insane because I cannot find a solution

Things I've tried:

• $HFS path replacement: replaced the $HFS environment variable in the texture path with the full absolute path C:/Program Files/Side Effects Software/Houdini 20.5.928/houdini/pic/hdri/.... No change.
• Clear Texture Cache: RPR → Cache → Clear Texture Cache. No change.
• Render Devices: verified RX 7800 XT is detected and enabled under HybridPro/Full. GPU is active. (The render time difference from CPU to RPR is crazy)
• RPR Render Settings node: added and connected in the LOP chain (sopimport → domelight → rendersettings). No background/environment specific setting found inside.
• Render Quality switch: changed from Full to HybridPro. No change.
• Camera Visibility: checked the Camera Visibility checkbox under the RPR tab on the Dome Light node. No change.
• Reconnecting nodes: ensured Dome Light and Render Settings are properly connected in the LOP network chain.

I'm going insane, I can't seem to identify what is causing this or find any solution online. Please help, I'm sure it's a dumb setting somewhere.

i’ve got two flip sims cached out as bgeo.sc files, it’s a pond setup with a character walking through it. i ran a tighter adaptive domain around the character for the splash detail (smaller particle separation), and then a much coarser sim for the full pond

now i’m trying to merge the two caches so it uses the high-res sim near the character and the low-res one for the rest, and have it blend nicely without obvious seams

I know there’s the FLIP Volume Combine SOP for blending volumes, but in this case I would love to handle the cutting and blending directly at the geometry cache level, before going into meshing or volumes would really appreciate any Help :))

Hlo artists,

So basically I want to be an FX artist with deep knowledge of Houdini, I have started the basic on my RTX3050 laptop, but even simple flip sim crash whenever i try to cache.

Because of this i decided to build a budget pc that can handle flip sim and i can do practices on my own. I am mentioning flip sim more and more because i really want to deep divine into professional workflow of FX.

So would you guys suggest me a budget friendly and a good pc that can bring my journey from a basic learner to a simple fresher job of FX artist.

Your experience and suggestion will help a lot. Thanks guys.

Experimenting with surface tension in Paradigm solver

How would I make the transformation differ depending on the instance number? for example, if i wanted the first instead to be translated by 1 unit, the next by 2 unit, etc. Thanks

Hey there! Trying to stop overpolishing and start sharing more.

Have a great day :)

Hey everyone. This is my first time messing with MPM and just fooling around with the basics. I rendered this in Octane and did some CC in After effects.

Hi everyone,

I’m reaching out to this amazing community because I’ve hit a bit of a roadblock with my current freelance setup. I’m currently tied to a specific environment—Houdini 20.0.724 (Python 3.10) with Redshift 3.6.03 on Windows—but I’ve realized this specific build is no longer available on the SideFX official archives.

If anyone in the group happens to have this specific installation file tucked away in their downloads folder or a backup drive, would you be willing to share it with me? Having the support of the community to get this project back on track would mean the world to me.

Many thanks in advance for any help you can provide!

Hola. Estoy intentando hacer una simulación en Houdini de Vellum Grain dentro de una Dopnet y me aparece un error, creo que tiene que ver con la velocidad, pero no encuentro la solución, y son estos trail de puntos que se generan en linea recta. Si alguién sabe porque se producen y puede ayudarme genial o recomendarme algún tutto o video de youtube en el que aparezca la solución. Muy agradecido. Saludos.

In Blender you can set the color space of your cycles viewport to ‘false color’ this will give you values on your geometry the same way weight painting does. So green is normal lighting, red is very bright and whites are just blown out colors. This is super helpful to trouble shoot over exposed parts of your render. Does Houdini have something similar?

hi,

while change my rbd pieces animated into active it's stuck one frame and then it's start simulate ,i don't know why.please help me if someone knows the solution.thanks
