27:18 If you turn off "Write Properties as Static Values" please do NOT unlock the shaders. It's basically a more generalized version of lock in and you definitely want either that on or have the shaders locked in. With this off and the shaders unlocked you are unfortunately uploading something very unoptimized for GPUs, sorry. It's definitely my bad for not communicating this with the warnings properly and I will change that in future versions. If you find a specific material that breaks with it turned on I would appreciate a bug report on my github with as .zip of the shaders and cginc files. I can't fix issues that I don't know about after all! Aside from that, this is a very good tutorial for optimizations that you can apply in unity! 23:00 Small tip here. The button to the left of the individual texture size actually shows you what materials the texture gets used in when clicked. Makes hunting for dangling textures a bit easier.

Thanks for the advice and corrections d4rk. Many times if I had Write Properties as Static Values ticked a lot of materials on Dotty models would break, I'm not sure exactly why next time I upload an avi I'll try to send in any bugged mats I find. Anyways, I ended up just unticking the Static Values thingy and I did run exactly into what you said where the avatar would become extremely frame heavy after and I couldn't figure out why so thank you for explaining that. I also had an issue where uploading avi's after converting to the optimised model would bomb my CPU usage to 100% usage on all cores even with my i9 13900k. Could that have also been from unticking the Write Properties as Static Values box? Also thank you for pointing out that button to hunt textures, that makes life so much easier, I never knew ^^

[@d4rkpl4y3r_vr]

@@akiwooLive do you mean 100% CPU usage while uploading the model? If so that is expected as the optimizer makes new shaders with added features like shader based mesh toggles etc. Those new shaders need to be compiled which unity does with everything your cpu has to offer and it can take quite a while to do.

[@omniaesthetic1256]

I hope you keep the tutorials coming, as I learned so much from you and want to know more! I am planning on reworking my custom avatar from scratch in a new Unity project, and I think a lot of the things you showed here will be a HUGE help. Some of those plugins you showed absolutely blew my mind. I wish I knew they existed beforehand!

[@phantom7767]

This is such an incredibly well made tutorial! I uploaded my first model today and this is helping me quite a lot.

[@pacman-dm2ky]

Thank you for all your help your video will definitely go in my favorites for favorite guide on the Vrchat making/optimizing community! ^^

[@All4thlulz]

Thanks for sharing your process of optimisation. In the chaos of trying to optimise purchased avatars this is a surprisingly easy method to follow. Now if only my friends weren't so scared of Unity...

[@AlmaEmma]

I'd feel so incredibly lost without your tutorials oh my god, you're a lifesaver! Unity can be so confusing at times, I'm really glad you go so in-depth with everything! THANK YOU!

[@Cragsand]

Aki being coherent and giving actually useful instructions! Amazing, keep it up 😉

[@tranphongtran2296]

Thank for the instruction, really helpful for my case.

[@Cyb3r-Kun]

Thanks a lot this was an amazing tutorial

[@Chomper_r]

wowow im feeling so optimized right meow

[@UsagiHorror]

Thank you so much for this 😭

[@tonyscragaloni9274]

This helped out so much thanks Aki! Do you think you could do a tutorial on adding tattoos?

[@pat-play_boy5608]

i love that cow ears

[@roguewitxh]

Thank you so much for this!! I've been wanting to learn to create VRC avatars for my DJing in game. Just a body to feel comfortable being and a body that I feel like really really represents me. I'm always so fascinated by people who can create things like this. My girlfriend makes models, and it's so wild to watch her. Also, lol, she grumbles a lot when the program crashes and she loses progress xD Anyways, solid props to this video

[@TheGodkick]

Now I can finally optimize my degen avatars yay

[@galarawr]

I was able to get it down but the tediousness of it all is still torture 😭 video very helpful ty

[@loveshock846]

You should get rid of all anystate toggles aswell or even better, make direct blend tree toggles.

[@user-uv5is7og1v]

Any advice for optimizing quest versions?

[@keselectric773]

I have a question and its kinda dumb in a way but can you use dazz 3 for vrc avatars likes these that you have??

[@EmiTheyThem]

Hi! After I do the "unpack prefab completely" 5:41 i'm unable to build and publish the model. Is there any missing step? I constantly get errors from all over the place, that before doing that do not happen-.

[@PhoenixHellcat]

D4rk is saying it don't work on quest is there another way to reduce material slots for quest it's the last part I need to do

[@mentosnetwork4774]

why do I need the dynamic penetration system

[@Slipdash]

Ur avi is really cute

[@Konprise]

you are so cool

[@oitsnana]

Should we do this to all avatars?

[@Lumaxes]

holy cow my frames are so high now

[@mrpmaewmaew]

hahaaaa, pun intended?

[@tenjikat]

when i add d4rk as a component the script isnt actually showing up, it just says d4rk and theres no options. im trying to use it on an avi for quest, any help would be appreciated :)

[@Redfox-ge5lg]

What dose build fail mean?

[@LeafyKatRR]

it says my avatar is using too many bits 262/256? how do i fix this??

[@Yutaru]

imagine walking in japan and carrying a vtuber in your arms wait wha

[@Xen_J]

turns invisble when i use it for quest

[@MoarPye]

I learned a lot but I'm still so stuck. I have an optimized avi by Sohvi which is rated as 'Good', then I add a beard to it, move it into the head on the armature, give it a new material derived from the hair texture Sohvi uses, and with just that addition the performance rating is now Very Poor... So I followed all the steps of your D4rk's Avatar Optimizer section, and it showed like it was gonna fix all the problems... Reduce the skinned meshes from 2 back to 1, poly bones from 16 back to 4, something about atlases... Only, it didn't do any of that. I've ended up with an Opti version of the avatar that reports all the same problems when I try to upload it. Still 2 skinned meshes, still 16 poly bones, etc... I even deleted the original avatar from the Hierarchy completely, just to make sure it wasn't getting picked up by mistake, but no dice. Trying to get one beard to work has given me 5 days worth of headaches and frustration so far...

[@DynamicPudding]

The upload page should tell you what is causing it to be rated as VERY POOR. Is the beard too many polygons? As soon as the model is over 70,000 polygons total, it is automatically reduced to very poor.

[@epiquewenqa]

okay so, my overall performance is still Very Poor. How do I get it to Good?

[@A_D_Forevers]

im in the same boat. This is a tutorial im trying to find/look for. I want my avatar to at least be poor or below

[@kassixo]

Interesting, but can it optimize an avatar with high poly to a green one? : /

[@Freezorgium]

Nothing you can do with a high poly count except maybe delete unnecessary parts of the avatar (like alternate clothes you don't use), or, if you're feeling brave, going to Blender and decimating stuff.

[@KimeraJin]

The ''create optmized copy'' don't get on for me, stay gray and i can't use.. not sure why tho.. but despite great guide!

[@tenshik3769]

Did you find a solution for this? I am getting the same problem. ;-;

Same issue here :[

@@mimimeow2833 If I remember correctly, when I got this to work, it was the object for GoLoco on my avi that stopped it from running. I could be misremembering though

Fun fact i have a acer nitro 5 that as a rtx 3060 and it can run Minecraft and any other games at a solid 60 fps but vrchat A game with very simple graphics somehow get my fps to on average 30 to 45 fps when there are a lot of people in a world and when i mean a lot i just mean 15 to 30 people :d Btw I'm not playing in vr

[@stranger.granger]

I can has more tutorials? =3

[@techiesimmer]

how would one obtain the avi file if you picked up a public avi ?

[@XIxR3DEEM3RxIX]

Interesting tutorial! I think I'll memorize the one and the other. I also like your avatar in the corner. What's also interesting for me is your voice. If you allow me this personal question: Are were you born as a woman? Or are you a transgender? If yes, you worked very good on your voice! I'm curious how you exactly worked on it. If the question is too personal for you, feel free to just ignore my message. ;P

[@KBLola]

You are sooo cute, tysm for the tutorial 🥺

[@YuriHonakoVr]

ty baby girl love ur voice but girl ty
