Broken Shader Replacement
With Cubed once being one of the majorly supported shaders for a very large time period, a lot of creators of avatars and worlds used it. with it no longer being supported in the new VRC update, it would be useful for Cubed and other decrepit shaders to be replaced with a standard or another fitting toon shader if possible. This is especially important because certain versions of cubed are currently so broken in the beta that they flicker rapidly, in world and on avatars. something that comes to mind immediately is the risk of causing epileptic attacks if someone is sensitive to the flickering. It can also appear in worlds, not just avatars, which given how long it takes to update content for some people, there is a moderate window of time where things will likely remain broken like this. simply suggesting people to update their avatars and worlds is not enough as people have their own lives, and some of the shaders in question have been in use for over a year I can safely say. that means there is years of content to fix.
Whitelist ParticleSystemForceField component for avatar/world interaction.
The ParticleSystemForceField component new to Unity 2018, combined with "external forces" module can open up a whole new breadth of avatar/world interactions not seen since Ik controlled GPU Particles. Mimi made an example showing what this component can do: https://i.imgur.com/yglb74H.gifv For the module to be useful, it must be allowed on avatars so that (combined with IKFollower) leg and arm positions can emit forces. Doing so can enable new types of 30dof interactions not seen before between avatars or between avatars and particle systems in worlds. Worlds that wish to block avatar particle interactions must only uncheck avatar layers including Player, MirrorReflection etc. For this reason it should be safe to allow avatars to carry this component without impeding world creation. https://docs.unity3d.com/2018.4/Documentation/Manual/class-ParticleSystemForceField.html
https://docs.unity3d.com/Manual/Constraints.html This system seems to be far better suited to perform a lot of task previously accomplished with other comments, while providing additional options for avatar creators Allows limb copying without fixed joints (allowing avatars with multiple arms or legs) Allows using world particles in situations that IKFollower doesn’t allow (Attach to non-IK-following bone) that previously required fixed joints I believe these allow you to Animate holstering / unholstering weapons without needing to duplicate the mesh (IIRC, FinalIK supported this) Aim/LookAt constraints can be used to replicate hydraulics pistons or other mechanical joints for robotic avatars (previously this could be achieved with dynamic bones any maybe FinalIK) These components likely can be used to achieve other effects. These components hopefully won’t have the disadvantages of the systems they replace, such as; IKFollower: only allowed on IK-following bones (As per documentation) Rigid Bodies: Known to break in Combat enabled worlds (https://vrchat.canny.io/bug-reports/p/avatar-rigid-bodies-break-in-combat-enabled-worlds) Rigid Bodies: Some configurations of joints can drift out of place over time or during teleports.
 Client Hang on Exit
When closing the client (tested closing from in-game menu) VRChat seems to go through the motions of a proper shutdown (avatars despawn for a few frames and then I'm kicked back to SteamVR) but the app remains unresponsive on the desktop. It requires a manual task kill to fully exit. Probably a known issue but just adding it here for issue tracking.
Particles cause game breaking local lag
Why hello there. Since the past two months we animators had to endure a game breaking bug for us. We did very very very much testing and it seems like particles, which are on bones that are disabled and triggered on using a gesture nearly always cause incredible lag. from 90 to 11-30 FPS Which reaches 1 fps with people around. BUT THE PROBLEM IS, this is not always the cause. Sometimes it works without any problems all, sometimes just one particle system brings incredible lag, as tested by a friend. Sometimes triggering a sword causes lag, only a sword. This sword always caused lag, tested on many different avatars. But another sword never lags. We just don't know what exactly causes those lags. BUT THEY STARTED WHEN YOU MADE CHANGES TO THE IK. Please check your IK again and what you changed, something in there destroys everything for us, acting is not possible anymore and we are all demotivated to even keep animating. Please Vrchat Staff, hear and help us. - Your Animation Community
Crashing within joining any world within certain id's
the only solid example we have of this is within the clover bar zero map ( https://www.vrchat.com/home/world/wrld_cd1cfd81-6101-4830-9884-056d1621a7ad ) where when exiting to any world at all we crash instantly not even hitting the load screen. i tried 5.6 worlds and several other worlds that i thought may contain the issue, i have had no luck with any kind of instance in several rooms to replicate the issue. all i know is that its perfectly repeatable in the clover bar. if it is there then that means it can be on other maps that use whatever asset got corrupted there causing this issue. here is the example that madvicius brought. he was the finder of the bug. https://youtu.be/YJfaN3maiMI?t=32 thanks for reading and i hope 2018 comes out great! im excited to see this beta develop!
Worlds using Substance Designer materials causes scene to fail to load (Only happens in VRChat)
This involves any world updated to 2018 using substance designer materials and would get this error: ERROR: Built-in support for Substance Designer materials has been removed from Unity. To continue using Substance Designer materials, you will need to install Allegorithmic's external importer from the Asset Store Should be fixable on VRChat's end as for my projects files is using the importer and loads the scene no problem and i am sure its fixable on VRChat's End.
 Player isn't loaded into instance for them but others can see them
2019-09-15 Cyan's stream: https://youtu.be/aTFYWDQcsRM?t=2278 He is still in the Initializing screen, and talking to his stream chat. He then gets kicked to a new instance. I see him in the instance and can see his IK and hear him. My stream: https://clips.twitch.tv/TemperedTangibleCookieVoteYea
 Changing the animation with slider don't work
the problem is that in vrchat that does not work now, the utilities of this are many, such as changing the weight of the postprocessed with a slider, or rotating objects with slider, this only occurs in vrchat, in unity it works correctly. expected: https://gyazo.com/1156dbd8803fd302ee1ae2d8fa2dc7f4 in vrchat: https://gyazo.com/281a4fdec21cbca6d205829dffe4774b id of the testing world: https://vrchat.com/home/world/wrld_f6c2e33f-9552-4949-82e3-fc5b02197290 How does the system work: https://drive.google.com/file/d/1nPdNMcuvgysUgCvxxrxXfrhpao1l268F/view?usp=sharing
 Some shaders on non-2018 content do not appear correctly
Avatars with standard unity shaders uploaded from previous versions are now invisible. Avatars with poimoi and certain other custom shaders are now invisible as well. But certain other shaders such as a custom matcap shader I bought from the unity store still works. It might be the shaders themselves not being designed for this version of unity, but I am not sure.
