VRM0.0 vs VRM1.0

[A1TA]

What's the difference?

[Squiggy8440]

different program entirely, .0 is essentially the public alpha, less censorship with the models too. but more wonky with everything else. 1.0 is basically the open beta. and in the future there will be a massive update that will allow the models to be changed to different files instead of just .VRM, going to potentially fix the blendshapes for better tracking and allowing items and potentially whole models from booth that aren't VRM to be converted and used in the studio. but this is just rumours.

i dont know what censorships squiggy implied here, there is no mechanism that would check how your model looks and if there is something to censor. but the differences between vrm0 and vrm1 are real.
in short: the differences are so big that it may happen that you load a avatar of the wrong vrm version into a program and it looks really wrong or straight up doesnt work because its incompatible.
sadly the original article on https://vrm.dev listing all differences/changes has been taken offline. i found a more incomplete list here https://help.cluster.mu/hc/en-us/articles/26313185878553-Examples-of-VRM0-x-appearance-changes-impacted-by-VRM1-0-support

from what i remember vrm1 bones are different? but more easy to spot are all visual differences, since the shader changed. this can lead to textures being shown incorrectly (for example like they are white instead of having the right colors), applied filters looking off and other unexpected wonkiness

so for YOU as the user, it probably doesnt matter as long as your model is compatible with where you want to use it. in my opinion neither is better or worse objectively as a format itself, but either can feel worse if your chosen vrm format ends up incompatible with your tools.

my personal tip is to add [VRM0] or -VRM1- or something like a little note to the file name of your exports, so you always know what format your exported vrm model is (since both will only be listed as a vrm file, no way to check if its 1 or 0 unless you have a software that can only load one not the other)

Thanks for such a great response!
I use VRM posing desktop and have not noticed the difference yet, except that when you move the model, her hair is not static, but moving.
