The code to support these edge cases was becoming more and more unhinged and illegible. Can still tackle it later if we really need it.

Potential optimization in CreatePrefabObjectLookup This helps a bit when cloning larger prefabs, not sure how much it will reflect in our benchmarks, on my machine the gains were quite small.

Revert "Improve player spawn performance" so we can optimize for go clone/creation performance This reverts commit 318474ee16bf9e057c1e8fbc8e2ee7877cf4dcd2.

Fix scene hierarchy right click (context menu) delay

Always refresh PrefabCacheScenes PostLoad even if the prefab didn't change. Ensures types of older assemblies are refreshed. Should fix issue where TypeLibrary.GetType() would return null when reconnecting to a server. The root of the issue was that typelibrary got refreshed on reconnect while the prefabcachescenes were not.

Automatically break prefab instances if part of the instance is reparented to another game object. A warning is emitted when this happens.

Use engine spline class

Some minor spline tweaks I forgot to backport from scenestaging

Spline Class (#1817) General purpose spline class for 3D. Uses a composite 3D cubic Bezier curve under the hood. Shape and behavior of the spline are controlled through points and handles. Two consecutive points and their handles define one segment/curve of the spline. The spline can be turned into a loop (Beziergon), which combined with linear handles can also be used to create a polygon. Splines are useful for animations, camera movements, marking areas, or procedural geometry generation.

Added Object property to WrappedMethod<T> (Fixes Facepunch/sbox-issues#7497) Fixed Show Interpolation Debug not being able to be toggled in the UI. If a ConVar value is a boolean, use its integer form. Fixes Facepunch/sbox-issues#7503 ActionGraph: add warning frame for graphs that can't be saved Fix case where empty editor scene is opened Fixes Facepunch/sbox-issues#7026 Added Show Hitbox Debug option in Debugging Menu in the editor. debug_hitbox ConVar. Can debug hitboxes in the editor or in-game similar to Show Interpolation Debug. Fixes Facepunch/sbox-issues#7505 Update mouse capture position if we get new absolute pos while locked (eg when unfocused, tabbed) Keeps cursor position predictable/reliable, stops occasional out of date position being restored and yeeting my mouse across the screen Only SetCursorPosition while engine window's got mouse focus, prevents unwanted movement in editor Add bitmap loader for IES files, treat them as images Do InputRouter::OnWindowActive based on engine window (not app) focus, fixes click-to-focus going thru as an input and shooting or whatever IES should be using RgbaF16 to avoid banding Default WindowedLocalInstances preference to true Remove logic to migrate from old project cookie, editor layout locations Fix default layout raising cloud browser, do asset browser instead Invert Ladder climbing controls when looking down (just like half-life) Fixed previous Show Hitbox Debug displaying BBox hitboxes in the wrong place Standalone: projects that only have the VR control mode enabled should automatically launch in VR, otherwise default to using the `-vr` launch param Moved DirectoryMetadata from Project Cookies to Project Config folder.

Instead they have a "Result" node which has a variable amount of inputs defined by the user - You can change the preview type of a Function Output so the value can be previewed while working on it - Dragging a `.shdrfunc` file into a Shader Graph (or a subgraph) will create the subgraph node - When "Add To Node Library" is set to `true` on a Shader Function it will be added to the Right Click -> Create menu - Double Clicking on a Shader Function Node will open the Shader Function - GraphCompiler now keeps track of the current Subgraph stack when compiling the preview and the output code, fully supports subgraphs within subgraphs. - Constant nodes now have a "Preview" input when you're in a Shader Function - Can Right Click -> Create Custom Node with a bunch of nodes already selected to instantly create a Shader Function. Will automatically create all the input parameters and result outputs. - Texture Parameters/Attributes are fed the whole way up from each nested subgraph since you cannot define a default texture in the `.shader` file. - Subgraph Nodes are now colour-coded Green and Result nodes are now colour-coded Blue https://files.facepunch.com/CarsonKompon/2025/January/28_18-05-OddAsiantrumpetfish.mp4 Require DropOwnership() to clear owner instead, document exception Remove Parameter.GetDefaultValue() and grab the current value as the default value Fix Default Color Editor in Subgraph Node Properties Subgraph Node ColorEditors are now bound to the defaults properly Add [SkipHotload] to RcSortedQueue comparator Simple AssetPicker displays Cloud Assets in a separate tab by default (with the option to combine them like it used to be).

Optimize ComponentList.GetAll by getting rid of LINQ The combination of recursion and LINQ allocated a lot of garbage in GetAll, this would result in a heap reallocation during many GetAll calls. Removing LINQ yielded a nice performance improvement. Getting rid of the recursion gives another tiny performance improvement, but not big enough to justify the reduction in code readability. I can not show results directly for ComponentList.GetAll, because the function executes too fast after the optimization and is no longer captured by the sample profiler. But here are the improvements for PhysiscsWorld.OnIntersection, which makes heavy use of ComponentList.GetAll internally via InvokeListeners<T>().
