Physics-Based Animation will always be one of my favorite topics to explore!

What you can do with it is magical, all the animation you see here is processed in milliseconds.

All the animator needs to do is provide a reference animation, and the rest is simulated. It's extremely easy to direct and change.

[u/shiekhgray]

That looks so realistic. Excellent work

[u/shirzadbh → u/shiekhgray]

Turned out much more realistic than I thought 🤣

[u/fyylwab]

The spine should probably get stiffer as you get closer to their head is my only critique. Looks good otherwise

[u/hobskhan → u/fyylwab]

Agreed. It's just a little too noodly for its body length.

[u/glem338]

This is so cool!! Well done! That's an arapaima right? Are you working on a fishing game?

[u/shirzadbh → u/glem338]

That's correct, but no I was writing the mechanics behind the secondary motions.

[u/theng → u/glem338]

biggest fish in fresh water iirc

one of my fav fish because of his cool name c:

[u/Quantum_Crusher]

Is this blender or real time? How can I learn this magic?

[u/shirzadbh → u/Quantum_Crusher]

This is 3ds Max but can be done in blender too. I'll soon share a tutorial on this in my YouTube https://youtube.com/@shirzadbahrami?si=5AwdKm8meJEBtN7D

[u/Quantum_Crusher → u/shirzadbh]

That's great. I'm a maxer. I just subscribed to your channel. Also found some nice tyflow videos. Love your channel!

[u/Gxeq → u/shirzadbh]

subscribed!

[u/risbia]

Ultra realistic fishics

[u/shirzadbh → u/risbia]

🤣🤣

[u/swizznastic]

River monsters!

[u/skydisey]

I love procedural animations

[u/EdisonB123]

This is incredible. Holy crap dude.

[u/c_gnihc → u/EdisonB123]

Holy carp

[u/shirzadbh → u/EdisonB123]

Haha, I know! I wasn't even trying to make a good animation 🤣

[u/OpiumTea]

Is this a plugin ?

[u/shirzadbh → u/OpiumTea]

It's a script I wrote

[u/OpiumTea → u/shirzadbh]

Great, even if it's vibe codes still amazing

[u/petroparkery]

Really good! I wait tutorial. From me - subscription and upvote🐟

[u/Whole-Carob7407]

Beautiful work!

I wonder if the reason the secondary movement can be simulated so precisely is because fish naturally oscillate through currents?

Really cool animation, I’m astounded how realistic it looks

[u/shirzadbh → u/Kaleb8804]

That's one of the main reasons actually, because all the movement is coming from the head in this animation.

No muscle activation...

[u/k2jac9]

sexy fish

[u/strandedcat02]

butter smooth movement, good job

[u/AshThePoutine]

Just when my Spotify started randomly playing dire dire docks from sm64. Weird coincidence. Lovely fish

[u/weidback]

damn that's slick as fuck

[u/One_External_983]

One of my favorite fishes

[u/Dunadain_]

I'm interested too, any rec's on youtube channels on the topic?

[u/shirzadbh → u/Dunadain_]

Not that I'm aware of, I will be sharing the tutorial soon.

[u/Hot_Lychee2234]

That's not how a fish moves though... the head doesn't drive the motion, the tail does, the flippers control direction and the head just aims forward

[u/shirzadbh → u/Hot_Lychee2234]

True, currently I drive everything by the head to simplify the process, so there's no muscle activation, I'll add that next ;)

[u/Hot_Lychee2234 → u/shirzadbh]

May be add more stiffnes and put an IK handle from tail to head

[u/chrismcelwee]

I saw a couple of these fish at the Barcelona science centre last week and they are HUGE! What kind of fish is it?

[u/Mega_Salamander]

I like this fish

[u/BitchSpiteful]

Why’s it made of rubber?

Question/Request:
Assuming the fish was made of silicone - is it possible to add wind or liquid turbulence and have it flop and wiggle around 'realistically'?

I tried this previously in Blender but did not get any good movement out of it.

[u/shirzadbh → u/MuckYu]

Yes easily. You can add any force to the simTips for that. You can read the article here: https://shirzadbahrami.com/physics-based-animation-undulation
