Look guys, he's got a baby, things have been crazy, he probably hasn't had a lot of sleep so it's totally understandable if he's saying "verticee" mode instead of "vertex" mode. So please, keep watching his videos, it's ok, he's just tired and things are crazy right now.

Lol he’s always said that, it’s not a baby thing. I still watch him though just cuz he’s good and I think he’s funny.

[@eyyman1133]

I like him saying that

[@cashhcoww]

The actual reason for this is not setting the scale, you'll run into problems about 10 minutes later with UV unwrapping. Just hit Ctrl + A and select 'scale'

[@vectornine]

That's how we say it in Australia

[@00syaoran]

hes saying vertices. plural of vertex. what does the baby has to do with that? whats your point?🤷

[@ehsanradmard]

Hey man, I just want to say something and I hope you and other people gonna read this. it was one month ago which I decided to learn Blender. I visited many youtube channels from 3D artists (Which better to not mentioning their names) I watched and started learning from them and I realized I am leading to somewhere unprofessional! THEN, I started watching your Donut tutorial and I FELL IN LOVE with your teaching. from placing sparkles by holding Ctrl to snap it on the donut's face. To CHAIR tutorial and how to Duplicate Screws materials. WOWWWWWWWWWW.... PLEASE, PLEASE, PLEASE teach us more. And to all viewers. If you wanna become professional and more curious about Blender. Just watch blender guru. I am the one who watched hours and hours of some CGchocolate, bla bla bla, videos.. and this man shows you where it must goes! Wish you a happy life with your beard which your wife allowed you to still have it. And happy to hear that you have a child now. Congratulations.

Just noticed that mine was "inflating inwards".. Solution: Select all faces and flipping normals fixed it. (edit mode: Mesh > Normals > Flip)

[@dragonpanda2379]

Would it be better to use a negative pressure value or have the red sides of the normals facing outwards?

[@erikrichard413]

For anyone wondering if their faces are inward facing. First check the face orientation on your mesh. You can do this by selecting the "Show Overlays" tab which looks like two circles at the upper right hand corner of the viewport. Clicking this and selecting "Face Orientation" will show if your normals need to be flipped. If the faces are red, you need to flip them.

[@fastenseatbeltnow]

Had the same issue here. Flipping normals solved it, thank you! The cushion looks perfect now at frame 9. But the normals are red. Is that bad / how do I solve it?

[@marschrr]

@@fastenseatbeltnow Well, I have never seen red normals (not saying that that might not exist, cause I can't say that I'm an expert either haha) Maybe select whole mesh of faces with "recalculate outside" (mesh > normals > recalc. outside) could do the trick. Btw, to my knowledge, read means the Seams for the UV unwrapper, ain't them?

[@marschrr]

@@fastenseatbeltnow Also, setting the object shade to smooth sometimes is an easy way to reveal messy normals (since blender will use normals info to do the interpolation caclulation between faces to render the smooth shading)

[@giuseppiallegro]

Thank you! One day, I will remember to check that. Today was not that day.

[@elFulberto]

8:01 I think it does make sense physically. What you are doing by applying pressure is inflating the cusion from the inside. And then you create a hole to let the "stuffing" escape and generate a sort of reactive force that propels the cusion in the opposite direction. Basically you are creating a cusion rocket here.

Just a late addition for you: if you go under cloth sim and enable "internal springs" and set tension to 0 and compression to 0.05, and leave pressure at 10, you get a nice, controlled inflation that looks very natural.

for those of you having problems inflating your cushion inwards, you have to check the "custom volume" checkbox, and play with the "target volume" slider, use value 1, and works very well, I'm using blender 3.5.1, hope this helps.

[@peterhorvath7343]

Thank you!

[@Grimmers]

I found the issue to be applying the scales flipped my normals inside out for some reason (scaled it negatively?). Simply flipping them again in edit mode let it inflate properly without tweaking custom volumes or negative inflates.

For anyone having problems at 7:36 (the cushion inflating inwards to the point that each side goes towards the opposite one - kinda like an infinite vacuum), simply select the cushion in object mode and scale it along the y axis and that should weirdly solve the problem. From this point on, you can even scale it back to the original size you had so no worries. Don't know what the problem is, but thought to save you up some time. Cheers.

[@alexocurance3951]

I have tried to ignore gravity and let it be default value of 1 , but reduced the vertex mass to 0.01kg and the collision worked without any gelly effect should try playing with vertex mass under the physical propreties

[@blenderguru]

I’ve tried that, but as it takes time for it to collide the cushion loses its shape. Then you need weight painting and it never looks as good.

I love how you explain the whys, and what will change if you change this and this setting. And not just "type these values and you'll have the exact same pillow".

[@SilentYuki]

For those with Blender 2.8 that don't want to update to higher version now, there is a work around. Do everything exactly as in this tutorial but instead of adding pressure , and Force from SHIFT+A menu and place it inside the "pillow" object at its center. Make the strenght about 200 - 400. Either way awsome tutorial as always.

Hey andrew, I've basically done most of your tutorials back in quarantine but stopped once I've finished the anvil and chair, "I don't remember which is 1st ", and I've seen that you made more videos, but I lacked the motivation to comeback to 3D, but I decided to give it another try and just make awesome stuff in blender with your tutorials, all I have to say is thank you Andrew keep it up.

[@michaeljohnson8406]

Thank you so much for your tutorials, you're the best. I didn't like how the pillow inflated so much in the middle. I experimented with "internal spring" setting everything to zero except a very small (0.2) compression and playing with "max spring compression length". I really liked the effect

[@SilveraGacha]

This might help at 17:09 & 19:00. You may have to click the arrow pointing down next to the picture of what looks like a camera and then press apply for certain versions of Blender. (I think I have version 2.93.1)

Thanks Andrew! Very informative tutorial!

[@MAY-bm3lh]

About minute 12:00 If you're a 3.4 users like me, and your pillow doesn't seem to puff right and it gets sucked from inside at first, in "physics properties", under the "pressure" tab you can turn the "custom value" on, and set "target value" to something around "0.500" Hope it helps!

To anyone who got stuck at 7:35 with the pressure simulation, you need to make sure that "pressure scale" is set to 1, opposed to the default of 0. I believe blender must have added this option since 2 years ago at the time of the upload

[@theonetribble5867]

Activating internal springs setting Tension to 0 and Compression to something small like 0.1 produces a relatively realistic simulation as well. You even can have gravity be turned on. I assume that pressure is better for something that actually has internal pressure like a balloon or similar.

[@CorentinHarbelot]

the most useful and well made tutorial with EXPLANATIONS!! Thank you!!

[@annp_blender226]

If you have a problem with the simulation. It should help. I noticed that Andrew has less loopcuts to the end of video. It's 7 horizontal line and 10 vertical line. You don't need to delete a cube and make another. Press Alt and click on 1 loopcut, then press tab g and merge your loopcut to top or bottom (or left/right). Do it with every lootcuts. Than press A and M and click - by distance - doubles will be deleted. than you can add new loopcuts. I hope it helps :)

To solve falling through objects with gravity simply add 'collision' physics to the parts that pillow passing and turn on 'object collision' in cloth properties of cushion. That combined with mangling with pressure and tension might get more realistic shapes. (especially when you want very soft, puffy pillows)
