SDK Bug & Feature Requests

This is kinda weird, but basically its kinda annoying because usually when I upload an avatar I hit the check box and click upload and when it's done, its done. It's been like that forever and it's pretty much just muscle memory. But now the checkbox in the beginning is gone and now it comes up as the "copyright ownership agreement" at the end of compiling, where you have to click "ok" before it actually uploads to vrc. I think this change should be reverted or have this agreement come up at the beginning instead of at the end.

SDK ver 3.8.1-beta.1 When setting platform overrides, which avatar you have selected when pressing build & publish still matters and it attempts to build & publish the avatar you have selected instead of what you specified in the platform overrides. I consider this to be a bug as the user already went out of their way to set a platform override, so I think that should take precedence. An easy way to get this is to be on the android build platform and have your PC avatar as the selected avatar, obviously with your android version set in the platform overrides, and then build and publish with just the android platform set as the build target. The build will fail with avatar validation failed.

When clicking Build & Test, SDK packs the world into a .vrcw file in c:\Users\[username]\AppData\LocalLow\VRChat\VRChat\Worlds\ When using VRC Quick Launcher, it reads the files inside of that folder and creates a list of worlds that you can run locally. Looks like since 3.7.6 the .vrcw file has its name lowercased, like scene-standalonewindows64-world_name.vrcw and for some reason VRCQL doesn't recognize that as a valid world name. If you rename it to scene-StandaloneWindows64-world_name.vrcw then it appears in VRCQL just fine. PS: world's name is lowercased too, while it wasn't before, although it works for VRCQL either way.

If we call IVRCSdkAvatarBuilderApi.BuildAndUpload just after changing visible avatars like changing scene or adding avatar to scene, IVRCSdkAvatarBuilderApi.BuildAndUpload may fails. This is because that in BuildAndUpload VRCSDK sets blueprint id and then awaits somewhere, but control panel may resets blueprint id with console log Loaded data for an avatar we do not own, clearing blueprint ID , after awaiting VRCApi.GetAvatar. If control panel reset blueprint id while IVRCSdkAvatarBuilderApi.BuildAndUpload is in progress, upload API call may fails. https://github.com/anatawa12/ContinuousAvatarUploader/issues/75

After upgrading to World SDK 3.4.0, when I entered play mode in ClientSim, I got the error "Destroying GameObjects immediately is not permitted during physics trigger/contact, animation event callbacks, rendering callbacks or OnValidate. You must use Destroy instead." The errors comes from internal SDK code, the IsBlacklisted function. Stack trace is linked in an image. I narrowed it down to a scene with two game objects: One or both objects have an UdonBehaviour (can be an empty script) Both objects have a collider (Box Collider in my case) One or both of the colliders need to be set to Trigger One or both objects need to have a Rigidbody The error occurs the first time the colliders intersect. The error shows up in the real game too, not just ClientSim. I was able to reproduce the error in a brand-new 3.4.0 project. As far as I can tell this error is not causing any problems, but it is annoying. Given it's related to IsBlacklist, I'm worried there might be a security concern here too.

VRChat is interested in allowing the VRChat SDK to be able to build & test content on mobile devices. Currently, only PC content can use the build & test feature. Other platforms must build & publish instead.

I tried to upload world on Linux . But, it's failing with the message "Last built VRChat scene could not be found. Please Test/Compile Full Scene (slow)". "Last Build" and "Build & Publish for Windows" button does not work with this message, but "Build & Test" can work and I can local test it.

VRChat is interested in allowing the VRChat SDK to build and publish on multiple platforms automatically. For example, you might be able to publish the Windows, Android, and iOS versions of your world without interacting with the SDK three times.

that's it.
