Blender Tutorial - Advanced Cloth Simulation

[@hi9313]

This is really excellent. I particularly like how quickly you get to the point in your tutorial

[@tejngx]

Still the best flag tutorial to date.

[@blenderzone5446]

great tutorial!

[@oobleck9213]

Classic Pax. In my head - you're David Mitchell. Thanks for showing me how without even hesitating to draw breath between words.

[@writersblock8493]

TY sardi... this was the best I came across albeit many years later

[@cineblazer]

Vertex Parenting! THAT'S WHAT I WAS LOOKING FOR! You have just saved me.

[@mikedimples]

You're so skilled at controlling the program. I'm just learning and hope to get to your level someday. Thanks for taking the time to create these awesome guides.

[@theinhabited]

Thank you!, been banging my head on the monitor for 24 hours. Yours is the first tutorial that made the crucial point that it had to be either 1 or 3 vertex parents. Strange this though, it would be helpful to have a wider option.

[@eknight2904]

That solved one of my sim issues I had for a long time. i tried all kinds of things but never thought the idea of vertex parent would work - no documentation was saying it would. I will try to enhance my own flag sim with it. Thank you for this great tutorial!

[@Forcemaster2000]

I've done cloth sim flags before, but never thought of doing a rope with the cloth sim, thanks for the tutorial!

[@stanleyleland4204]

Great fun! I found the rope collisions to produce some unexpected results. I expect the cloth simulation will become even stronger in the future . Thank you for making this video available.

[@bananamuffin5614]

Awesome tutorial! Right to the point. I love to see more cool fire/smoke/ explosions simulation tutorials. Keep up the good work!

[@soogoonu]

excellent tut - very dense and quick

[@lstagnaro]

Great tutorial !. I like the speed you are progressing that makes the video short, and I slow it where i want if needed. I also learned a number of neat tricks on how to edit meshes. Thanks a lot !

[@justingooligan7059]

outstanding ... answered my initial question i was looking for about attaching cloth to another cloth. your tutorials are very good. Thank you

[@stapleshotz]

It's nice to find a tutorial that I don't have to speed up to x1.5. Thanks for not treating us like toddlers.

Your channel is a treasure trove. Thank you for the great tutorials!

[@800pieds]

Very useful and to the point. Vertex parenting, didn't know about that.

[@warwicklambertcom]

The best flag animation tutorial.....

[@craftycanadian8282]

Very well done, taught me everything I need to know in one perfect length video.

[@reality990]

Man thank you very much! Before your video i didnt now aboyt Vertex parent and what it did! 9 years, but such useful!!!!!

[@dharmalingeswarparasa1609]

I have been searching for this for hours.. Thank-you sir... (ctr+p) thank God, you made this vedio..

[@GameTubegames]

Please re-create this tutorial again in blender 4.0 ❤

[@summerwimmer9329]

I've been able to follow along for the most part, sometimes by switching keymaps to Blender 27x. I have cloth > physical properties > bending model set to linear too. right now, I'm in the last couple minutes of the tut and ran into an issue with how the flag reacts with the rope. still figuring out a fix, but the issue is the whole edge of the flag spazzes and clips into the rope edit, in case you or anyone else has that issue too: I saw one of Sardi's comments where he said try redoing it, so I went back to a safety file I had and retried connecting the flag. I cleared the cache and dissolved half of the edges I had cut (was 28 x 28 edges, now 14 x 14). by the time I made the safety file, I had already messed with the cloth sim settings and applied a subdivision modifier (and maybe one other mod, but idr what it was). it seems to work fine now

[@unfa00]

Great tutorial, many thanks for sharing the knowledge!

[@AngusGiorgi]

Thank you Sardi, amazing tutorial as always!

[@GSTPD]

Thanks very much Sardi, Both flag tuts were my introduction to wind force and cloth sim. I releived to see just how easy it is...Blender never ceases to amaze me. I am doing a kitesurfing kite sim. Could you please do a kitesurfing kite sim tutorial? Tim

[@SardiPax]

I'll give it some thought Tim.

[@jazon65]

gooood tutorial, i hope you can show more fire and smoke vfx in 2015....

[@marauderpictures6815]

Great tutorial.

[@Avekis_73]

Awesome tutorial , thx a lot

[@BradKligerman]

excellent tutorial, thanks!

[@wizendweaver]

Thank you Sardi.. Great video! I see there is a gradient in the material. Can you remember any of the other settings.. For how the flag looks like material?

[@SardiPax]

Hi, the woven material look is a texture applied to the Displacement input on the Material output.

[@wizendweaver]

Thank you Sardi.

that was awesome thank you so much, it helped me solve an issue i was having. Subscribed now

[@CTRL_SMarcos]

Excelente.Gracias por los tutoriales.

[@doc.4zure514]

hy really nice..but plz can you tell me what programm you use for screen cast?

[@pencilgun4934]

Hi thanks for the tut. A quick 911 question. I have a shot where I need to do a stretching effect, kinda like cloth but the fabric actually needs to stretch out. I am rendering this out in close up so I need to see the pattern stretch. I have done cloth in Blender before but I cant remember if you can get this stretching effect or how. Imagine spreading your fingers while holding pantyhose. With the gaps stretching further apart as you move your fingers apart. Any thoughts? Thank you!

[@SardiPax]

I don't think the cloth simulation can do that. You can add tension up to the You may was to look at Shapekeys. If you Enable Dynamic Mesh in the Cloth sim then add shape keys to stretch the mesh, the cloth sim will still function where there is enough slack in the cloth for it to move.

[@pencilgun4934]

O.k. great info thanks for getting back to me so fast really great help. Yeah heard of shape keys never used that before though. How about using morph targets?

[@andriy_babak]

Hello! Thank you for your tutorials! May I ask you to show how to make a seamless looped animation (it seems to me that in Maya that's done with animation cache blending, I am sure it could be done in Blender as well)?

[@SardiPax]

Hi Andrey, thanks for the suggestion, I'll give it some thought.

[@RomboutVersluijs]

Just an idea. What if you make a lower res rope and add hooks to couple verts. Then also add hooks to the linked to the other hooks. This way the high res curve will follow the lower res curve. I think that should work and takes less calculations, if im correct though

[@vmartme]

Hello Thank you Sardi. Can you please say did you ever try create paper Airplane flying with force Wind? Thanks for all tutorials ;) Vlad

[@SardiPax]

+Vladimir Marinović Martini Not so far no, although it's an interesting idea.

[@nickangellondon]

Oh good god I've been trying to make this work for the past five hours ... at least! Everything is great UNTIL I try to attach the flag to the rope and it just goes crazy, flapping about wildly. I've applied the scale ... I've made sure I'm clicking in the correct order ... I've made sure that the vertices selected rather than the objects ... it's driving me bonkers. Gaaaaaaaargh. I know this tutorial is almost eight years old, but it's the only one I can see that features an animated rope and I now have a bee in my bonnet and want to make it work for the sake of my sanity!!!

[@SardiPax]

Hi Nick. Probably some defaults in Blender have changed since I made this one. Usually when cloth sims are causing problems, the best thing to do (sorry) is start again. Approach it by creating a less sub-divided 'flag' and rope at first, increasing as you narrow down on the settings. Without seeing the file it's hard to know what might be the problem. Sometimes the issues are related to the Cache file, so make sure you've completely deleted the bake and re-baked every time you alter any geometry.

[@nickangellondon]

@@SardiPax Thanks so much for this Sardi, I only just saw your reply - much appreciated that you took the trouble.

[@arturmachura000]

Hi, nice tutorial very usefull but I got a question. Is it posible to parent diferent vertex of cloth to diferent objects?

[@SardiPax]

Yes, you can do that, although I think there is a limit of 3 parented vertices.

[@arturmachura000]

Thank you for quick answer. Should all vertex of the cloth be in this same vertex group or for every parent in a seperate one?

[@debbieblackwell5170]

So beautiful

[@SzymonWarunek]

i did not think so it is possible to simulate attached 2 cloth objects together just in Blender! i did similar thing in 3ds max,but by using the simulator reactor which is already outdated and got removed from 3ds max.Hopefully it will be possible to receive similar effect in 3ds max

[@lazylizarts]

Nice tutorials. I just want to know if I can parent entire stretch of vertices to the other moving object (in this case the rope)

[@SardiPax]

Three vertices is the maximum other than the entire object. You could just have 3 vertices along one edge of course.

[@lazylizarts]

@@SardiPax I am looking for a solution for a parachute with the edge of canopy (the entire edge) to be child of the struts of the parachute. I don't want the gap between two like inshore a gap between the flag and rope ( between the pinned vertice)

[@SardiPax]

@@lazylizarts You could animate the edge of the parachute with shapekeys, so just simulating the movement of the cloth. Alternatively, you can add multiple pinning pints for the cloth without actually parenting the vertices. You would need to animate the movement of the cords to follow any movement of the pinning points (again done with shapekeys).

[@lazylizarts]

@@SardiPax kzbin.info/www/bejne/n6LYiqGMhcSaoJo

[@lazylizarts]

that is what I achieved using pinning , hook and vertex parenting

[@b1na276]

this flag tutorial is better than blender guru. thanks

[@szilard063]

HI SARDI This video is amazing!!! Is there a possibility to make it seamlessly looping?

[@SardiPax]

Hi, in animation terms that would be quit tricky but a quick way is to find a point some way in that roughly matches some frames near the beginning then quickly fade between the two.

[@Confuseddave]

Greg Zaal did a video on this for CG Cookie, but it is unfortunately behind their paywall: cgcookie.com/tutorial/creating-a-looping-cloth-simulation/ The technique outlined is pretty technical - if I remember it involved baking out and saving the simulated animation as a point cache, (.mdd file), meaning you can reload it as a series of shape keys (a large number of keys- one per frame!). Then you find two points in the animation where the model looks pretty similar, and join the loop together there. Since they're shape keys rather than frames in a rendered animation, you can blend the shapes together pretty well and it should look better than crossfading two rendered frames, but it might still look a bit weird if you can't find a closely matching keyframe.

[@Confuseddave]

Rather than simulating the rope using a tube, I'd be inclined to simulate it as a string of vertices with no faces, and then use the solidify modifier to turn them into a volume. Also, if you want to go the overkill perfectionist route, rather than vertex parenting the flag to the rope, you could vertex parent two empties at the points you want the flag to connect to, and then use hooks to move the pinning vertices with the empties (which should match them to the rope).

[@_whybe8446]

thank you so much.

[@tylermustardloooser386]

thanks, now I can make a realistic noose

[@BlenderRookie]

That was great, but my old brain got lost right away.

[@cjkalandek996]

Whenever I animate a character with a cape in Blender and when I make him move too fast, the cape literally stretches and even rips. Does the "bending" option for the cloth physics prevent that?

[@SardiPax]

There are a great many settings for cloth but usually the problem is trying to move it fast. There should be a subframes option so try increasing that which will make Blender do more calculations per frame.

[@MrRollie51]

epic as usual & thanks

[@psifis]

Excellent

[@HEEROCKSS]

Thanks, exactly what i need

[@adrien7457]

Hello ! I love your tutorial but i have a problem and i can't find a way to fix it. When i'm attaching my flag to the rope by using CTRL + p, the flag is not correctly following the movements of the rope and is just sliding on the x axis. This is really unrealistic unlike you did in this video. Can you help me out ? Please

[@SardiPax]

Did you 'attach' vertices that had been added to the Pin vertex group? If they weren't in the vertex group they won't work.

[@adrien7457]

@@SardiPax uh, yeah, I did this

[@adrien7457]

@@SardiPax Oh man, i'm sorry. I'm a fool. I was struggling on this tutorial for weeks but the problem was the pin group. I so stupid lol Thanks for you tutorial man, it's great

[@DidierSampaolo]

hi Sardi, thanks for your amazing tutorials. I got a situation here : when I attach the flag to the rope, it seems to go crazy and sometimes "jumps" to the top or the bottom. The line between flag and rope is moving really fast too. (I think the vertex on the rope are moving like they shouldn't). Spent a few hours on this without a clue. Any insight would be appreciated. Anyway, thanks again for your videos, I already learnt so much ! :)

[@DidierSampaolo]

Found ! I was missing the "even distribution of the bevel" part. It works like a charm. Hope to see more from you soon !

[@aksherpatel8344]

i do not get what sardi did at 1:47, i know he clicked shift and middle click but i tried the same thing and it wont do anything, about creating a Hook or something?

[@SardiPax]

Hi, I believe I just used Ctrl R to add loop cuts then I move the mouse to drag the new loop cuts up before left clicking to fix them in position.

[@MurrTV]

I am having issues rendering the rope. It looks fine as I am baking it, but the rendered output looks bad. Any ideas?

[@SardiPax]

Hi, that depends on the problem. Is it snapping around a lot or jiggling too much? Is it an issue of Normals getting messed up, if so maybe try adjusting Bending and damping.

[@MurrTV]

I will try to post two pictures. First is during a preview of the animation after baking. I am happy with the movement of the rope.

[@MurrTV]

I can't seem to post a screen shot. I am sure it has to do with the normals. Great tutorial, by the way.

[@SzymonWarunek]

max users should try to receive exactly the same result of this dynamic simulation.I still wonder if 3ds max which has mass fx is still capable to achieve this result like Blender? i started using this program,is becoming eveng better than 3ds max in some areas,especially dynamic calculations...

[@clockwisestudio5440]

Szymon Warunek 3ds max is more than capable of doing this. With even less work :) But Well sometimes is not the Program that makes good results but the user :) Right? :)

hy i have a really problem with parenting to the rope....i do ctrl+p when flag and rope is selected.then i press parent to object..then i go in edit mode of the rope and choose 3 vertices and press ctrl+p and make vertex parent.but the flag doesnt go with the rope...why?i looked 5 times youre video and did everything like you.but it doesnt work..i use the newest blender...plz help me.

[@SardiPax]

Doc. 4ZURE hi, select the flag, then the rope, press tab to go into edit mode, select the vertices on the rope, then ctrl p.

[@doc.4zure514]

ahhhh i think the problem was that im parenting the objects .....and i only should parent the vertex...ok ill try it thx...can you plz tell me what program you use for showing wich button you press..?

[@violetacolcer2149]

thanks a lot mate

[@BARSHAPRODUCTION]

How to add colors to the flag...where is that portion..?Plz help...

[@SardiPax]

There are many ways to do that. You need to add a material which is one of the options on the right.

[@CosmosBFN]

nice

[@marauderpictures6815]

Great tutorial, but EVERY TIME, when we get to the point where the rope is supposed to drop after I click "cloth", the rope twists and disfigures at the top where it is supposed to be attached to the pole. EVERY TIME!!!!! And it just keeps twisting and disfiguring itself. It's very frustrating.

[@SardiPax]

+Marauder Pictures Hi, make sure you don't have any odd vertices/normals along the length of the rope, also try 'Applying' Rotation & Scale (CTRL A) to the rope object.

[@starwarzillian8129]

Hi, i had the same problem. I had set the resolution of the bevel on the curve too high, and later on when i added the cloth it was going crazy like you said. So what i did was make sure that i had it to a resolution of 2 (like in the video), and it worked perfectly.

[@starwarzillian8129]

Hi, i forgot to mention is that i had made my flag pole as a collision also and it was going haywire. By un-setting the flag pole as collision it worked fine. Sorry i didnt mean to post so much but hopefully this will help someone.

[@RamonPatrique]

nice and fast.

[@Keyuser1972]

[@DeadGrunt1]

I am just learning, so trying to follow along takes a little longer and I miss steps and my flag on a pole looks like horrible piece of toilet paper on a stick. But I will keep trying.

Hi, you may want to have a go at this tutorial first as it's a slightly less complex cloth sim - kzbin.info/www/bejne/nXK1e6t7ed-abM0
