This is for if the avis turn pink either in unity or in game. Id download the separate files instead of the bundle to make this easier to do, cause if you get the bundle it will make it harder to find the specific shaders you need for each avi as well as make it easier to mix them up cause you kinda have to do different things for each avi. I did have unlit shaders and textures on when i tried to fix these, not sure if it really helped at all. Doesn't seem to fix it
For Fiz, you have to go into the materials list and find the ones that are pink and switch the shader to poiyomi toon(if you have it) or vrchats toon lite or toon standard. If your using vrchats ones you can usually use toon lite but if anything shows up black in game then id use standard cause that should fix it. If you use poiyomi you can just put on poiyomi toon and it should be fine. The pc version seemed to be the only issue. I don't think there was a problem with the quest version.

For Azzy, she doesn't show up as pink in unity but will show up pink in game for the quest version. That's if you get the popup when you go to upload her about shaders on her being not able to be used for quest, in other words just pc shaders. There'd be a list with it as well showing what shaders they are. So you cant use poiyomi toon with this cause its quest and it doesnt seem to like it. You just use vrchats toon lite and toon standard. So first you open the materials quest file when you look at the quest side of Azzy, then you find and delete the optimized shaders file in there. Then like fiz, you go into the materials list but instead you look for shaders saying Hidden/Locked when you inspect them. Then you switch the shader to toon lite or toon standard. Toon lite seems to work for all except the outfits and yellow pajamas. Use toon standard for those. That seems to work. You'll know you got all of them when you dont see the popup when you go to upload and no poiyomi related alert in the alerts tab in the SDK. The pc version seemed fine on this one. Otherwise they are nice avis. Atleast i like them :)
If you have any questions or issues with this or other issues entirely let me know. Dont be shy! Hope this helps!

GASPPPP OZZIE AS A WOMAN!!
There's only 1 other avi of her I'm so happy to add this version to my collection aswell <3
