Thank you so much I can't wait to try this!

[@mihaiwilson]

Fantastic, best explainer I've seen. Thanks for sharing this!

[@FF-FAN9999]

AMAZING TUTORIAL thank you so much. the physics on my character are looking amazing

[@xxerbexx]

then you need to adjust the collisons

[@dermopser8705]

Thank you for the video and detailed explaination! :)

[@CrazyRabbit0228]

Thanks! You explained very detail 🥰

[@yaoling_XR]

You are my life saver! You are a real superhero!

[@activemotionpictures]

Fantastic video!! Thank you for sharing!

[@jintor9061]

Great explanation, really helped me out. Now I just need to figure out wtf I did to my animation blueprint that broke half my other animations though...

[@Tenchinu]

applied this to a cat tail, and it works just as well :) the version in 5.0 works perfectly too... so think I'm gonna try and make this my default until I get rly good with the Physics Assets... the vein of my existence!!!!!!

[@pummelweed784]

Finally now I can have proper jacket physics

[@pokmeng6038]

wow nice

[@johnpark8542]

Thank you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[@maximosmalevitis8184]

Great Video! Very helpful! Although, I am still struggling with a small issue. I use hair as a separate skeletal mesh, so that I can change hairstyles and share different bodyparts between characters. How can I set kawaii up to respect the collisions of the body when I cannot reference it inside the ABP?

[@crossman1611]

This is a problem I'm encountering as well. Have not found a solution yet

[@gonfurnier6941]

Hi erbe! you are the number 1! I have a question, when you talk about the skirt, you said you had to use the default physics asset editor because of the constrain problems, my question is, Do you add constraints in the physics assets for the diagonal space of the Leg, and once you have that constraint how do you implement that physics asset in the player? Are you using rigid body? Thanks ! I just need you to explain deeper the solution for the skirt. Cheers! Im from Argentina

[@crossman1611]

I would also love to know this.

[@rumboraka1]

Thank you for the video! My hairs simulate awesome now in gameplay! With the skirts I have a huge problem. No matter the cross constraints still can't get the skirt physics to be like yours in the video. Do you have any tutorials or course on how you did the skirt physics?

[@hatsunemikuchannel2023]

14:40-15:30-15:40: Thanks! 😮😮😊😊

[@nierautomata9654]

does this mean we have to rig or create bones too for the hair mesh ?... will these extra bones not cause trouble when importing to unreal ? sorry for the questions i am just curious how you did your character .. i have tried making characters from blender then importing to unreal but i didn't know its possible to rig the hair for unreal engine all i know is cloth simulation but this kawaiiphysics seems better to look at.

[@xxerbexx]

you can rig whatever is a mesh. sure, rigging from blender to ue4 isnt always.... that nice. but once u figured it out it works. its a very common practice to rig hair and clothing, its more uncommon to use cloth physics for it. im actually, in this very moment finishing a rigging course. if you are intrested, im about to post a link on my discord soon.

[@nierautomata9654]

@@xxerbexx cool! yeah im interested to learn rigging from blender to unreal .. count me in for that course :)

[@xxerbexx]

[@davidryatta9563]

I use Kawaii for my physics solutions as it does world space movement in game far better then the glitchyness you can get from RigidBody on low end devices.. but I've not found out if its possible to bind the end of a chain yet, for end to end simulations.. like a rope bridge or decrotaive parts of characters attached at two points which RB does allow for

[@xxerbexx]

Pls watch the full video, in the end I talk about it.

[@davidryatta9563]

@@xxerbexx Am I missing it?.. I don't see you mentioning a solution for doing that. You talk about how theres no 'net' based support for binding phisics chains togther (very few phsyics solutions seem to support this), but no mention of binding the end of a physics chain so that retains it kinematic position like in the physics assett

[@xxerbexx]

​@@davidryatta9563 Let me be honest, i´v reat your comment in half sleep and awnsered in half sleep. sry if i sounded a bit condecending, part of my nature. My point in the end rather was, there isnt a simple/proper solution for it beside using unreals physic system. But attaching things to the end of the chain should be possible? You would need to take the end of the chain and pass it to the next connected component. Though you would need to do this with a delayed frame or on post tick, wich can give a hit on performence. But then again, didnt test that. Thoug again, i also probably wouldnt pass it along like that. I would probably use a master rig with set master pose to attach things. Ropes and Bridges... erm, yea idk, sounds like the most reasonable solution is the default physics system. its very sitation depending. kawaii physics generally is just for "look only" things, like a necklace on a character or so.

[@lltwy7535]

Thanks for sharing! Can you give a tutorial on tail parameters? No matter how I set it up, it feels weird.

[@xxerbexx]

I don't think a tail should be done with kawaii physics. Better would be control rig

[@eatmylaz0r]

Somehow the Limits Data Asset in UE5 doesn't show any proprierties. Pretty sure it's a bug, but since I dunno how to use C++ there is no way for me to fix it. :( Is this happening in anyone's project also? Is there a way to fix that? Great video btw, cleared out some things for me.

[@xxerbexx]

Sadly I have not directly tested it in Ue5 yet. I'm going to move to Ue5 when it's released. There are just to many bugs for me atm. But once I'm switching I might make a follow up video

[@RafaelBrum]

Instant upgrade for my Lobster. Thank you for that. Anyway, I'm trying to create a snake with this kawaiiphysics and the body doesn't collide with the ground even if I adjust the physics radius, It just pass through. Any idea how to solve it?

[@xxerbexx]

Yea, don't use kawaii physics for that as it won't collide with anything outside the kawaii physics asset

[@xxerbexx]

I wish it would but it doesn't. It only works inside the space of the character

[@RafaelBrum]

​@@xxerbexx I don't know why but my comment disappeared. Anyway, when I try to compile the game, it alerts me of something: "missing precompiled manifest for 'kawaiiphysics'. this module was most likely not flagged for being included in a precompiled build - set 'precompilefortargets = precompiletargetstype.any;' in kawaiiphysics.build.cs to override." Did you get this error?

[@xxerbexx]

@@RafaelBrum compile your BP? Or build the game? I have no problem with compiling, didn't build the game yet

[@RafaelBrum]

For those who had the same issue, put the plugin on the project folder, not in the engine folder for 4.26.

[@Stonefieldmedia]

Do you need to create an animation blueprint to use this plugin? I just want to do linear animations without having to make an animations blueprint for gaming. Is it possible? So little information out there on this plug in that is comprehensible.

[@xxerbexx]

Yes you do need one. But I have to tell you, not using a animation bp doesn’t sound logical to me at all

[@Stonefieldmedia]

What if I'm not making games but making linear video footage?@@xxerbexx

[@xxerbexx]

@@Stonefieldmedia if you have a character it needs a animation bp. Regardless of what you do

[@Stonefieldmedia]

I have skeletal meshes with rigs that use marketplace animations. I put the skeletal mesh in the sequencer, add the animation file to it and render the scene. Where do I need an animation BP in that workflow?@@xxerbexx

[@swrcPATCH]

how did you do the selfshadowing in a stylized way? or is it just pre-drawn?

[@xxerbexx]

thats my secret sausce, ill plan to start working on a course this month

[@firekernelcom]

Hi, check your screen recorder settings, i was watching some of your previous videos and this one, all of them look horrably blured, on 27 inches monitors i can barelly see attributes in unreal engine and so on, the feeling that my eyes stop working properly don't leave me when i try read something on those videos, like it 480P or something like that. I was check with other videos (from unreal official channel) they look much more stady, huge difference in quality, i was surprised that nobody is mentioned this, maybe they watching from phones with huge DPI i have no idea, but seriously check quality settings, i'm sure this can't be like that

[@xxerbexx]

My settings are absolutely fine. But I am working and recording in 4k. On a ultra whide monitor. So things are going to look very finicky on small monitors with less resolution.

[@firekernelcom]

@@xxerbexx i see, i watching your Character, Blender to Unreal playlist, on both monitors 24-27" full hd almost impossible to read something clean, ya it probably because of 4K, when i talk discord with friend he usually make fHD res only then i can see something. anyway thank's for info, especially about control rig, like and subscribe but eyes oh my eyes, just pain)

[@xxerbexx]

@@firekernelcom I'll see if u can do something about it. Maybe there is somewhere a option to make the u4 UI bigger

[@firekernelcom]

@@xxerbexx nwm i was found solution, 1440p work exelent! I just not see this option my fault, Edit: unfortunately not all videos have 1440p, but im ok with that)

[@kimma485]

It's such a good explanation, but it's a pity that it's a harsh and fast explanation for beginners to follow. I would appreciate it if you could explain it slowly and easily.

[@xxerbexx]

Its a video, you can watch it as many times as you want or slow it down. Sry but that was the most simple explanation possible.

[@user-dp4yg9vb1r]

ur head looks small ._.

[@xxerbexx]

thats okey as long as i have a big brain
