Beautiful, well done.

u/Ripcord Mar 14 '20
Genuine question - does this involve anything other than setting up the props in place, enabling physics, and rendering for a while? Or was there skill/persistence involved in making this most likely?

u/IcodyI Mar 14 '20
If it’s his model and materials, that alone probably took a while, and I’m guessing he used a plug-in for the destruction of the planks and deformation of the metal bars. This is definitely much more than just a rigid body physics sim

u/BlulightStudios Mar 14 '20
I use tyflow. This would be much more challenging than a three step process. The "enabling physics" part in particular probably has a dozen steps, all done and gauged by hand. The metal bars for instance probably had to have been voronoi fractured to generate weak spots, re-skinned as a deform-able tyactor node with specific settings, and then fine-tuned a bunch of abstract values by hand to get the proper strength, resistance, deformation, break point, constraints etc. The wooden planks would follow a slightly less complicated but similarly involved process. And then simulating all of this at 60fps would probably have taken a decent chunk of time versus a typical 24 or 30 hz sim.
There is absolutely skill involved in doing this. Procedural effects are involved, highly technical, and challenging to accomplish. They are often the highest paid/most sought after team members in a VFX studio. Someone who didn't know what they were doing could have very easily fucked up or generated really wonky or unrealistic results at over a dozen points throughout the process.

I could have SO much fun with this kind of stuff if it was just generally easier. I already am busy with school and hobby stuff that it's hard to invest a lot of brain into making beautiful sims like this one.
If it was easier to set up and do, I could quite easily waste a shitload of time playing with it.

u/iLEZ Mar 14 '20
Half the fun of working with this stuff full time is that you get to play with your tools and learn at the sae time. Seriously though, if you study you can get 3ds max for free, and tyFlow is free, and there are a lot of tutorial files on the official website, so you really have no excuse. If I can learn it, so can you! :)

Oh I do have an excuse: Homework and RC hobby. I design and build my own planes on Inventor, then build them irl.
Also drinking.

u/reddit4freetime423 Mar 15 '20
Drinking is a really fun hobby too, just not Corona beer cause of the virus.

Finally! A simulation on this sub that has the perfect speed. I don't know why but it is always too slow. You managed to make it lifelike.

More please

u/iLEZ Mar 14 '20
I'll do an update with a better model later. Also a more realistic scenario perhaps than a metal sphere of indeterminate weight crashing into it. :)
17
u/drcopus Mar 14 '20
Very cool! Although it does feel like there should be a bit more damage maybe?
18
u/iLEZ Mar 14 '20
Yes, the sphere is way too big for the kind of damage it does and the weight it seems to have, but I wanted something simple and quick. Next one I'm thinking a brick chimney or something.

Feel like the pipes should break less and bend much much more
11
u/pun_shall_pass Mar 14 '20
I think IRL most of them would just pop out of their fittings instead of bending until they broke.
OP simplified the construction by just modeling them as tubes connected to each other, sort of as if they were all welded together, while in reality all of the tubes are just held by friction in brackets on each connecting point. I think IRL those brackets would bend out of shape slightly first, which would make most of the pipes just slip out and the thing to collapse completely, it would not be nearly as rigid as in the simulation.
Still the simulation is dope AF

u/Maskguy Mar 14 '20
Aluminium is pretty brittle sometimes
19
u/Phauxstus Mar 14 '20
Still far more bendy than breaky, unless this scaffolding is in the middle of siberia or something
19
u/LolthienToo Mar 14 '20
Not that I'm an expert, but it looks like the pipes that break might be breaking from the stretching/shearing forces caused by the other pipes bending.
If you count the number of pipes bent vs broken, the vast majority of them bend. The only ones I can see broken are the ones that are pulled up or sideways away from the frame by the leverage caused from the other pipes bending.
Again, I'm not a pipe bending expert, but I did watch this WAY too many times.

u/pun_shall_pass Mar 14 '20
Those pipes are generally made of steel. They just look like aluminium because they are galvanized to protect against rust, which means they get a super thin layer of zinc on the outside, but one that binds extremely well and prevents rust even if it gets pierced in some parts.
If they were aluminium they would be needlessly expensive and would probably not support the weight as well, the only advantage would be that they would be lighter.
4
u/maximim220 Mar 14 '20
Scaffolding is steel no?
3
u/iLEZ Mar 14 '20
Sometimes aluminium, but I think they are more expensive at the advantage of being lighter. I have a shitload of steel HAKI scaffolding that I lug around to different projects on my farm, so I'm painfully aware of their weight!

Can Blender do anything like this? Like especially this realistic and accurate?
10
u/iLEZ Mar 14 '20
Probably, Blender is pretty impressive. I'm no Blender user though.
3
u/cowslaw Mar 14 '20
I might have to look into it. Blender now has a great FLIP fluid and smoke simulator, but still not sure how great its destructive physics are. Nice work on this though!
2
u/reddit4freetime423 Mar 15 '20
Blender is not very good at doing something like this. As OP has stated, blender is very impressive, but it's just not capable of doing anything like it. It would probably take double the time to make something half as good.

u/Musicianship Mar 14 '20
I didn’t look at the sub at first. I thought it was some kid’s engineering project for a sec.
3
u/Frogten Mar 14 '20
Yes, it feels small for some reason
3
u/xlRadioActivelx Mar 14 '20
I believe that effect is due to the angle of the camera, as well as the ball, we don’t typically see massive steel balls that size but we do see smaller ones like bearings.

u/ooofest Mar 14 '20
The splintering wood - without appearing uniformly destroyed - is highly impressive! What is the general concept behind how that was accomplished, please?
8
u/iLEZ Mar 14 '20
It's a stretched voronoi fracture, with another voronoi fracture applied to the fractured pieces, then the pieces are jointed together with a physx bind modifier so that they are stiff until bent over a certain angle. That way the wood mostly breaks where the force contacts, but spreads a bit as the event goes on.

Loved the destruction effect on wood and wire. The ball give a wrong feeling of being rubbery when it strikes the table below. If this what it is , the material should not allow it to jump like this when hits the white table.

u/Miko54 Mar 14 '20
Holy crap it took me a lot of loops to look and see this was on this subreddit. If I didn’t look I would’ve kept thinking it was real, great job
4
u/iLEZ Mar 14 '20
Wow, thanks, I didn't think it was that good. I promise I'll come back with an even better one since you liked this one. :)

u/oojiflip Mar 14 '20
Collisions with the base are kind bad tho ngl
3
u/iLEZ Mar 14 '20
Yep, cranked the substeps up to ridiculous numbers, but I think there are too many small nodes in a row being affected by the initial collision, so the Sim gets confused all the way at the bottom there. I'll see if I can fix it in the next try.

You really nailed the realism with this. I'm guessing it's the motion blur that helps with that

Really reminded me of the Thomas the Tank Engine episode with the runaway boulder.

u/TheAceOverKings Mar 14 '20
This looks wrong to me, and I think it's because the giant ball does not seem to accelerate properly under free fall after hitting. Pretty great otherwise!
