If this were a video then pretty soon the shirt will fall of even though I have done all the same settings as in the video. This same thing happens with all tutorials I can’t replicate none of them. I have tested everything with blöender 3,2 and now 3,3 and nothing works why is that ?
How it is possible that tutorials work in the videos, but my cloth simulation gives me just bs results that can’t be used ??? I’m getting pretty tired of blender not workin like it’s supposed to be.
I don’t know your Blender experience - but from my experience i can tell: you just miss one step or make it wrong - the whole thing can mess up. So either you start from scratch again and listen and repeat every single step in exact the same way the tutorial says - or you provide your blend file and we can check it out what might be wrong. And of course: it might even necessary to use the exact same Blender version as in the tutorial (but that’s a pretty rare case)
But you followed an older tutorial not in the older version and didb’t understand the workflow to adapt it to the (maybe) slighty changes in the newer version and you also used you own model (in different scale ??)… and now all tutorials are bad…
Simulations in general have dozen of parameter to tweak on… and you wanna master this by just following tutorials… also only free ownes…
I found the solution and it wasn’t that I didn’t do exactly what was in the tutorial. I tested this tutorial again with the tutorials own model and like " MichaelBenDavid" said it was the size difference.
I noticed that the tutorial model is alot bigger than mine so I did the tutorial with that and it worked also I copied the model and sized it down to my model size and then the problems started.
So in this tutorial and all the rest of them nobody never says that the model has to be very big and seems that when the model is small blender has impossible time to calculate sewing. I have the default cube as reference and as you see the size difference is huge!
Size is one of the most important parameters to every simulation ever… and this has nothing to do with blender… even in a real wind (or water) channel the smaller size of any test model has to be considerd… because the result on 1/10 scale model differ because water or air interacts differently… with 1/1 scale…
(Just in another thread:
Reality vs. Expectations … first one wins… ever…)
So if you follow a tutorial… then follow the tutorial… to the iota… then learn from it and make your own experiences…
(I know this… trust me… some tutors also make mistakes which only do not end into failure by chance and this isn’t related to likes in any way .)
Well, actually my video says exactly that, along with a number of other tips.
Shameless plug:
On the subject of cloth sewing/stitching I’ve more recently avoided doing that, it seems to cause more trouble then its worth. Instead I’ve been using shrinkwrap to match a more simple plane grid to the base shape and then modeled it from there.
That’s used as the basic object for simulation, while a second object is where I add all the details and animate it using the techniques I cover in the video above.
Even so, cloth sim is a complex process and it takes a lot of testing to determine exactly what works depending on exactly what you are trying to achieve.
@Engie yeah as okidoki said there is certain situations where things with proper real scale works better in computer graphics but also sometimes not really and then you gotta cheat on things. So well in the case of blender cloth simulation is a bit different how is handled, so the self and object collision distance parameter has this limitation (you cant decrease the parameter more than 0.1 cm), so the workaround for that is just to scale the model…
also take into account that your polycount matters if you have a very dense model you will need more self collision distance, next time measure the size of a single quad and setup a number like that in your collision parameter and then scale the model but if 10 times of scale isnt enough then scale 5 or twice more if needed…

or that 
and then agreeing…
