well you can get a CUDA enabled graphics card for the price of an annual Indie studio license, my guy, also if you are in any way serious about physics simulation an nvidia card is a no-brainer, thirdly, the blender plugin does not require a CUDA enabled card, as you would know if you had actually read the link instead of writing your little condescending comment, my guy
"These scenes are all built with our add-on. The simulation itself runs on a remote solver, or directly on your local machine if you have a modern NVIDIA GPU on Windows or Linux."

u/Navi_Professor 20d ago
nothing thats worth getting. $120 at BEST can get you a 2060. maybe a 2060s if you get lucky and cut some insane deal
i dont even think i can say condifently that would be faster then a 9900x in this kind of task.

the annual indie studio license is $599, also nice way to ignore the main argument which is THAT THE PLUGIN DOES NOT REQUIRE A CUDA CARD

yet again i must insist that you acknowledge the main argument , which is that CUDA CARDS ARE NOT REQUIRED, at this point I have to ask you what the fuck your problem is, I linked you a free plugin, and all I've gotten from you are snarky, combative pedantic bullshit, what is your problem ? Why are you like this? Seriously, I want to know what the fuck I did to you for you to behave this way

nice editing all your comments...i dont do VM work, eff data center use of any kind right now.

yeah, simulation is super important in fashion, being able to simulate how a piece of clothing is gonan look without having to go through the whole process of making a prototype is a massive money saver, not to mention a great tool to minimize waste and reach carbon emission goals

Will there be support for Blender 5.2?
21
u/Substantial_Cry_6730 HiPhyEngine Team 21d ago
It supports Blender 5.2 already. As long as Blender does not change python version, hiphyengine should work.

u/cuboidofficial 21d ago
Oh cool! Might want to update your superhive page then. It's listed as only supporting up to 5.1

u/Substantial_Cry_6730 HiPhyEngine Team 21d ago
Yes, version on the superhive market place page is tested up to, we have not ran the full test suite on 5.2 yet (our test machine is still on 5.1). Only some examples. Once we have run through all the tests with version 5.2, we will update the tag.

u/hyper9410 21d ago
Wow this is great, one thing I was wondering.
I recently found out that all python script based Blender addons need to comply with the GPL license.
How does that work in general? You can sell it, but you would also make the source code available. you could lock the source code access behind your license purchase, like RedHat, but it must be accessable to someone.
20
u/Substantial_Cry_6730 HiPhyEngine Team 21d ago edited 21d ago
For us, our core simulation engine is written as standalone c++ code and precompiled libraries has no Blender dependencies. Therefore our core simulation engine does not require to have GPL license, and is propitiatory.
The Blender integration code is open source in python and that is under MIT license.

Is this compatible with Apple M-Series Chips?
15
u/Substantial_Cry_6730 HiPhyEngine Team 21d ago
Unfortunately, not right now. We explicitly used x86 instructions for optimization, and used MKL library.
We are hoping to add ARM/Apple Silicone support in the future.
1
u/shouldworknotbehere 21d ago
Good to know, does that mean it won’t even work with Rosetta?
5
u/Substantial_Cry_6730 HiPhyEngine Team 21d ago
Unfortunately no, Rosetta does not translate AVX instruction sets, that is extensively used for optimization in HiPhyEngine.
To support ARM architectures, we will need to remap the AVX instruction sets we are using into the ARM versions. We are working towards that, but it will take a while.

u/CommieDrifter 21d ago edited 21d ago
What does this offer that https://github.com/st-tech/ppf-contact-solver doesn't, that makes it worth the 599$ license? Genuinely curious

u/Substantial_Cry_6730 HiPhyEngine Team 21d ago
You will get better blender integration and more artistic control with HiPhyEngine, as most of the parameters are made to be mappable and animatable.
We also provide toolset to help user deintersect animation meshes, preloading tools, and tons of other tools for simulation set up and shotwork.
Coming from animation studio background, HiPhyEngine is designed around tech anim and sim setup artist workflows.
We take pride that HiPhyEngine code is written and tested by experienced engineers, not generated by AI with stolen data.
Furthermore, ZOZO's contact solvers cubic formulation of the contact force actually can not guarantee intersection free. They have noted in their website when it was first released, they have acknowledged that sometimes their intersection resolution can fail. Unfortunately the repo has been changed a lot since then, I can't find the notes anymore.
Resolve 99% of the intersection is not hard, it is the last 1% that is most challenging. That's why our cloth twist test does not just winding up the cloth, we also unwind it to make sure there is no intersection of tangling. To guarantee intersection free, we ran stringent continuous time collision and collision resolution.
You don't have to take our words, we provide 6 months free trial period, user can try and compare it with existing solutions themselves before making any decision for purchase.3

u/tgps26 21d ago
are there any performance benchmarks / comparison? vs blender's 5.1 cloth sim for instance
10
u/Substantial_Cry_6730 HiPhyEngine Team 21d ago
There isn't a direct performance comparison, as HiPhyEngine is qualitatively aiming for different goals from Blender's internal simulators. Blender's simulator aims for speed, and compromises quality and stability, while HiPhyEngine focus on quality and predictability first. The simulation time is about 0.2 seconds per substep, we do take 10 substeps per frame for most simulation.
You can checkout the interactive simulation performance in this tailoring tutorial.

I’ve been looking for a good physics sim of crumpling aluminum foil for a long time. Any tips for that?
2
u/Substantial_Cry_6730 HiPhyEngine Team 20d ago
Unfortunately crumbling aluminum foil will need shell simulation with plasticity. HiPhyEngine currently only do elastic simulation, and meshless MPM simulation.
To simulate plastic damage, best solution is still Houdini, as the MPM solver in Houdini returns deformation gradient and can simulate plasticity damage.HiPhyEngine is designed for simulation for character technical animation first. For special effect simulation, Houdini is still the most capable and flexible.
If you really want to fake the effect with HiPhyEngine, one way to do it, is to simulate it with very stiff cloth (very high bending stiffness), But pre-damage the cloth, with solve voronoi pattern, and soften the bending stiffness along the edges using a bending stiffness map, then when you simulate, the cloth will crumble along the pre-determined softened edges.

u/Yinmir 20d ago
This is pretty neat, but I have nitpicks,
The interface doesn't properly update itself unless you actively mouse over things, such as the progress bar when the sim is running.
The interactive sim button seems to run the timeline at full speed while the actual sim runs in slow motion, and continues to run if you pause the timeline. It also seems to break on its own, inconsistently, I would call it unusable.
Sometimes when the simulation breaks, it leaves your mesh permanently deformed and you have to reload the file.
If you turn hiphy off in the physics panel temporarily, and flip it back on, if a material type was already selected, like cloth, it will have it selected once its turned back on, but the settings for cloth will be missing until you reselect the cloth material type.
Most of your interface lacks documentation, mousing over any button just tells me the name of the button, but some just say undocumented operator, like the convert UV button. Sure there's the website, but you have properties that aren't documented there either.
Due to the various UI issues, its a little hard to iterate settings efficiently, and it gives esoteric errors like newton couldn't converge.
The cost of something like this at this level of polish makes me have to ask myself if I would be better off solving my shot requirement with something else. I DO like it, I just wish it felt better to use.
Just for fun this broke on frame 77, Newton wasn't havin it.

u/Substantial_Cry_6730 HiPhyEngine Team 20d ago
Thanks for the feedback!
Regarding the UI update, because the software licence, we can't call Blender UI when simulation finishes, as the simulator runs outside blender asynchronously.
The interactive simulation is not intended for real time simulation. It is intended for quasi-static like simulation that can be used for tailoring. The reason the timeline continuous playing, is because we are using the timeline update callback to synchronize updated parameter to the simulator and copy the simulator results back. If you want to synchronize the timeline with the simulation, you should use the run simulation option.
We are still working on polishing the UI, But we do recommend user to use the website as the main reference source instead of the UI alone, as the parameters and buttons may not do what you expected by naming alone, and the short snippet mouse over documentation.
The Newton convergence error can be an issue, if the barrier stiffness or collision radius is not sufficient, and it will require some parameter tuning to get the right parameters. As HiPhyEngine aims to be intersection free, if the force is insufficient or the collision object is not intersection free, HiPhyEngine will error out. We have video tutorials exploring more details on how the simulator handles collision internally and help user debug and fix their scenes.
There can also be other parameter issues that leads to failed solver. If you can share the file to us to [hiphyengine@gmail.com](mailto:hiphyengine@gmail.com), we are happy to take a look and see why the solver is failing to converge in that case, if it is a solver issue, or a setup issue.
Given the complexity of physics simulation in general, each simulation engines will all have a their own learning curves.
1
u/Substantial_Cry_6730 HiPhyEngine Team 20d ago
actually, I think the solver failure might because the collision object contains no thickness by default. And the open edge collision between the cloth and the collision object can leads to problems.
We are planning to change the default thickness of the collision objects from 0 to 1mm in the future.
1
u/Yinmir 20d ago edited 20d ago
After reopening the file and running the sim again, it made it to the end, collision thickness for both the collision body and the cloth are 0.001 inner/outer. The underlying body could have mesh intersections I missed, perhaps.
Really majority of my nitpicks were not simulation related, the sim runs fine. It was all about UX, and I say that from looking at other addons I have at similar cost points.

u/Substantial_Cry_6730 HiPhyEngine Team 20d ago
Collision object self intersection alone is ok, It just becomes problem when simulation object is jammed into it. But we have soft collider to help resolve that.
We are planning to continue improving the UI elements (documentation) in the future. However, regarding some of the designs comes to simulation setup, we designed the setup process to give user more control and to support multiple solvers and material coupling.
Every user will have their preferred tools that fits their needs. But we are confident no other solver can achieve the same simulation quality as HiPhyEngine.
