[SDK][862] "Offline Test" option is broken with multiple clients

Please fix multi-client "Offline Testing" or provide a better way to test networking without a full world upload. The SDK provides two buttons for testing. One is for local testing and the other is for full uploads. Local testing, or "Offline Testing", still requires a network connection and also provides an option for the number of clients. While some things appear to work with only one client, when using more than one client, local testing breaks and behavior is unreliable. Since this is built right into the SDK, people believe that it is correct functionality and think that their world is broken, wasting many hours of debugging and more bad testing. Known issues: -Network IK only sends for master -OnPlayerJoined/OnPlayerLeft triggers do not fire -Sitting in stations force all clients to the same position -Object ownership does not act properly between clients -Sometimes only the master can execute ANY triggers -Some clients do not make it to the same instance -Some clients are kicked to home Previous canny relating to multi-client local testing was closed with the response that using the same account for the same instance is not supported. Users are required to log into different accounts. This is not a solution. The general user does not know they are required to have multiple accounts to test their own worlds properly. Multiple accounts can only enter the same world if the world has been fully uploaded. Some users also have a very slow or limited connection and uploading a full world is impractical. https://vrchat.canny.io/bug-reports/p/multi-client-bugs

VRC_Trigger SecurityException with VRC_AudioBank

player audio override broken for late joiners

When someone has been in the trigger for the audio override and leaves it he is still loud for people that join the world later as if still standing inside the trigger until he goes back into the trigger and leaves it again.

VRC_Midi Note In component multiple selection issue

The trigger object settings are broken when select multiple VRC_Midi Note In components. https://twitter.com/VoxelKei/status/1144270143255535617?s=20

VRC_DataStorage component breaks networked triggers

Observed as of Beta Build 743 Adding a VRC_DataStorage component to a spawned prefab will break networked triggers for that object. Either the receiving client will be unable to process the trigger, or they will be able to process the trigger, but it will be on the wrong instance of the spawned object. The effect is limited only to the object with the VRC_DataStorage attached to it. Objects up or down the spawned hierarchy work as expected. Repro: wrld_cb727742-a84c-4544-a749-4c9b70184e4d https://www.dropbox.com/s/bbe766rpzsgvxh4/DataStorageTest.unitypackage?dl=0 - Launch into the world with 2 or more clients - Using one client, Press each blue button to spawn some instanced data storage objects - Using the other client, attempt to interact with each spawned object. - Observe how interacting will either fail to elicit an effect on the first client, or cause the effect to occur on the wrong object.

SetMaterial action use wrong material named similarly

in progress

SetMaterial action use wrong material in some cases. It depends on how materials named. * Reproduce 100% if scene data is so * You can see at wrld_2d141628-bab5-461d-b0ff-7c81e1a0ebb0 * Tested with client 2018.3.2 built636, SDK VRCSDK-2018.10.02.10.29_Public REPRODUCE STEPS: -------------------- 1. Create new world (Create new project, make floor, add VRC_SceneDescriptor, assign Spawns point). 2. Create materials 2-1. Create two materials in diffrent folder. 2-2. Name these equal name. (Ex. "f1/Mat.mat", "f2/Mat.mat") 2-3. Change albedo color as visually identifiable. (Ex. Red to "f1/Mat.mat", Blue to "f2/Mat.mat") 2-4. Create two objects and assign each materials. (This step is for ensuring materials available in DynamicMaterials of VRC_SceneDescriptor. I used spheres in following screenshot.) 3. Setup SetMatrial action 3-1. Create two objects. Name t1 and t2. (I used cubes in screenshots.) 3-2. Setup VRC_Trigger > OnInteract > SetMatrial to self. And use each created material for material parameter of the action 4. Test Expected behaviour: Interaction with t1 changes t1 material to "f1/Mat.mat". And, Interaction with t2 changes t2 material to "f2/Mat.mat". Actual result: t1 and t2 change to identical material. 5. Additional test 5-1. Change material name of that is not appeared actually in privious test. Add characters to the tail of original name. (ex. "Mat111.mat") 5-2. Setup VRC_Trigger again. (This step need because VRC_Trigger doesn't follow material renaming.) 5-3. Test. The result doen't change. This means equal name is not true source of this issue. (If it is not reproduced. Try exchange materials name. It depends on reordering DynamicMaterials when SDK builds world. I couldn't get ordering rule enabling 100% reproduce.) MY ANALYSIS: -------------------- I guess the runtime behavior of Set Material action as follows: 1. Extract parameter string from SetMaterial action. Check it begins with "Assets/". If so, continue. 2. Remove charcters from beginning to last "/" . 3. Iterate DynamicMaterials of VRC_SceneDescriptor from head, and check if its material name (not include path and ".mat" extension) matches head of the string of step 2. If it matches, use that material. I think it should also use folder names section of specified asset path string. And of course, it should compare entire string. SCREENSHOTS AND LOG: -------------------- This is result of additional test. 1. f1/Mat.mat is actually red. 2. f2/Mat111.mat is actually bule. 3. Both SetMaterial use f1/Mat.mat Triggers actually use f1/Mat.mat and f2/Mat111.mat. > 2018.10.03 12:19:54 Log - [VRC_TriggerInternal] 15.12996 t1 via OnInteract executing [SetMaterial (False, 0.000, 0, "t1", Assets/iwsd_vrc/Issues/set-material-to-unexpected/Reproset/f1/Mat.mat, 0)] > 2018.10.03 12:19:55 Log - [VRC_TriggerInternal] 15.6973 t2 via OnInteract executing [SetMaterial (False, 0.000, 0, "t2", Assets/iwsd_vrc/Issues/set-material-to-unexpected/Reproset/f2/Mat111.mat, 0)] (Recently we had software version up. So this screenshots aren't taken with latest software. But I could reproduce with latest. It's same.) WORKAROUND -------------------- Name materials uniquely with long name. Don't use a name which matches the head of another material name. ABSTRACT IN JAPANESE -------------------- 概要 SetMaterial アクションが間違ったマテリアルを使う事がある。起こるかどうかはマテリアルの名前の付け方に依存している。マテリアル選択のアルゴリズムはおそらく次のようになっている。 1. SetMaterial の文字列を取り出す。先頭が「Assets/」であることを確認する 2. 文字列の先頭から最後の「/」までを捨てる 3. DynamicMaterials を先頭から見ていき、そのアセットの名前（パスと「.mat」は含まれない）が前述文字列の先頭部分に一致したら、それを使用する。これにより同名のマテリアルが別のフォルダに入っているとどちらか一方しか使う事が出来ない。そうでない方を使っている SetMaterial は間違ったマテリアルを使用することになる。この現象を起こすのに名前は完全に同じである必要は無く、使われる方のマテリアルの名前と先頭部分でさえあれば良い。

Unity Terrain grass shaders broken in VRChat

The hidden shaders Unity uses for Unity terrain grass detail patches falls back in VRChat to shaders that are not affected by fog settings and have cutout rendermode, forcing world builders to use the tree mesh part of terrain to render grass patches and that impacts performance a lot. The two hidden shaders in question are "Hidden/TerrainEngine/Details/BillboardWavingDoublePass" and "Hidden/TerrainEngine/Details/WavingDoublePass" causing all the grass in a scene to stick out of the fog. Dropping in this replacement shader that adds alpha transparency doesn't get picked up in VRC and gets reverted to the cutout shader without fog: https://github.com/Nition/UnityTerrainGrass Screenshots from Unity 2017 and VRC 2017 build showing no alpha transparency and fogging in VRC but working fine in Unity

Male/Female setting looks opposite

Version: SDK 2019.04.01.10.09 Description of the bug: Male/Female setting (Default Animation Set in the VRC Avatar Descriptor) seems to be opposite. When I choose "Male", the avatar becomes pigeon-toed, while when I choose "Female" the avatar becomes duck-footed. This behavior looks opposite.

[862] Teleport Player with align room to destination false can rotate the player

Using TeleportPlayer triggers and math, we can get the location of the player base. Doing this requires two teleports. When using align room to destination set to false, this will cause the player to rotate in unexpected ways. Setting align room to destination to true does not have the same issue. https://gyazo.com/1ffa2e007d07fed5eae86cabd464e043 Sample world using 2 teleports per frame that will cause the unexpected rotation on certain head angles. wrld_1c962617-81ff-4d14-926e-8408404176da

VRC_ObjectSync.TeleportTo by non-owner may cause location desync

If non-owner player calls VRC_ObjectSync.TeleportTo, the object change position and rotation only in his world. Other players (include owner of the object) still see it at previous position. In short, location desynchronization will happen. If the object is moving by physics (not in sleep state), this TeleportTo caller sees it at teleport target location at the instant, but it goes back to previous position. (I think it is because the object basically moves along owner's world physics calcuration.) I tested with SynchronizePhysics enabled, SendRPC Targets is All, client version 2018.3.1. Workaround: Call TakeOwnership before calling TeleportTo.
