1.5.3 - 2026-06-06

Material Preview

• Added the DreamShaderLang: Show Material Preview command, active only for a .dsm material file.
• Added a VSCode Webview preview panel with sphere, plane and cube mesh selection.
• Sends previewMaterial requests to Unreal over the local WebSocket on 127.0.0.1:17864 by default, and receives preview results and continuous frames.
• Falls back to the file bridge when the WebSocket is unavailable: it writes the request JSON and reads Saved/DreamShader/Bridge/preview.json plus Preview/*.png.
• Added the dreamshader.previewWebSocketPort, dreamshader.previewAutoRefreshDelayMs, dreamshader.previewTransport and dreamshader.previewLiveFrameRate settings.

1.5.2 - 2026-06-06

Callable Hover

• Hover on DreamShader functions, UE builtins and Substrate helpers shows return-value and output-pin metadata.
• Added output-pin hover for helpers such as Substrate.ThinFilm, keeping a fallback for older bridge manifests.

1.5.1 - 2026-06-06

Bridge, Packages and Templates

• Added parsing, completion, formatting, semantic tokens and syntax highlighting for the Template block.
• Added DreamShader bridge commands, status bar and diagnostics panel integration.
• Added package install, browse, update, remove and scaffold commands.
• Added command-palette authoring templates: material, function file, header file, texture sampling and noise material.
• Restored CodeLens and Inlay Hint registration after the extension activation modules were split.
• Bridge diagnostics refresh when Unreal updates Saved/DreamShader/Bridge/diagnostics.json.

1.4.9 - 2026-05-29

Function Builtins

• Added unified Function builtin metadata covering HLSL intrinsics, GLSL-style aliases and Unreal texture-sampling helpers.
• Completion, hover, signature help, inlay hints, semantic highlighting and the local diagnostic allowlist share one builtin list.
• The README and the Chinese README list the supported Function builtins.

1.4.8 - 2026-05-29

Layout and Region

• Added language support for the Layout = { Node(...); Comment(...); } section.
• Added parsing, diagnostics, folding, snippets and highlighting for Graph #Region / #EndRegion.
• Snippets, templates, README, formatter, document symbols and semantic tokens all understand the layout metadata.

1.4.6 - 2026-05-22

Volume Texture

• Added VolumeTexture / Texture3D language support, highlighting, completion, snippets and diagnostic coverage.

1.4.5 - 2026-05-18

MaterialExpression Fallback

• Built-in MaterialExpression completions are loaded from the language core as a strong fallback, so UE. suggestions include material-expressions.json entries even when the VSCode adapter services provide no project manifest.

1.4.4 - 2026-05-18

Reflected Expressions

• Reflected UE. MaterialExpression completion inserts a UE.Expression(Class="...", ...) snippet while keeping short labels such as Abs and TextureSampleParameter2D.

1.4.3 - 2026-05-18

Manifest Configuration

• The extension bundles a fallback material-expressions.json manifest, so reflected UE.Expression(Class="...") completion works even when no Unreal project is detected automatically.
• Added dreamshader.materialExpressionManifestPath, pointing explicitly at a generated Saved/DreamShader/Bridge/material-expressions.json.
• Added a language smoke test for manifest-backed reflected MaterialExpression class completion.

1.4.2 - 2026-05-10

MaterialExpression Metadata

• Language metadata synchronized with the reflected MaterialExpression support in the current DreamShader release.
• Added completion, hover, formatting and diagnostics for reflected texture sampler metadata such as SAMPLERTYPE_*, SSM_*, TMVM_* and TGM_*.
• Added UE.StaticComponentMaskParameter(...), UE.CurveAtlasRowParameter(...) and reflected TextureSample helper snippets.
• Fixed the inlay hint signature lookup for the document-specific reflected UE expression manifest.

1.4.1 - 2026-05-10

Dream Shader Function Files

• Added .dsf file association, command-palette template creation, import completion, clickable imports and workspace indexing.
• .dsf diagnostics allow ShaderFunction, Function, GraphFunction, Namespace and VirtualFunction, and reject material and layer asset blocks.
• Added local diagnostics for statement-style multi-output ShaderFunction / VirtualFunction calls.
• Explicit import extensions are preserved: import "Functions/F_Tint.dsf"; resolves as a function file and is not rewritten to .dsh.

1.4.0 - 2026-05-10

Parser-based Language Service

• Extension version updated to 1.4.0.
• Rewrote the DreamShaderLang language service core around scanner, parser, context, symbol, completion, diagnostic and provider modules.
• Completion, diagnostics, semantic tokens, folding and document symbols all route through the new language core.
• Fixed broad completion-scope leakage between the Inputs, Graph, Function, Settings, Outputs and metadata contexts.
• Fixed Base. output completion so applying BaseColor no longer inserts Base.BaseColor.
• Added parser-based formatting, cross-file import indexing and function cycle detection.
• Restored deeper local diagnostics covering ShaderLayer / ShaderLayerBlend shape, VirtualFunction options, Graph callable argument counts, Graph out variables and MaterialAttributes member writes.
• Added Substrate / Strata types, syntax, completion and diagnostic hints.
• Added language smoke tests for section-aware completion and diagnostics.
• The README became the English primary document, with a new README.zh-CN.md.

1.3.4 - 2026-05-10

Templates and Material Layer Keywords

• Updated the built-in templates and snippets to produce more usable project-level DreamShader skeletons.
• Material Layer language support and templates moved to the recommended ShaderLayer / ShaderLayerBlend keywords.

1.3.1 - 1.3.2 - 2026-05-09

GraphFunction

• Added GraphFunction language support for reusable graph-node helpers that call UE.* nodes and expand at the call site.
• Single-output Function and GraphFunction calls participate in local diagnostics as Graph value expressions.
• Multi-output Function and GraphFunction calls still use the explicit out-variable syntax.
• Top-level block templates moved into templates.js; keyword completion inserts only the keyword, while entries such as ShaderFunctionTemplate and GraphFunctionTemplate expand the full template.
• Added GraphFunction snippets, completion, hover, signature help, symbols, folding and local diagnostics.
• Added a local diagnostic suggesting GraphFunction when a plain HLSL Function block calls a UE.* graph node.

1.3.0 - 2026-05-08

Material Layer

• Added MaterialLayer and MaterialLayerBlend language support, snippets, semantic tokens, folding, symbols, CodeLens, completion, hover, signature help and local diagnostics.
• Added Material Layer output-shape and Material Layer Blend MaterialAttributes input validation.
• .dsm / .dsh diagnostics recognize generated Material Layer assets.
• Material Layer snippets use explicit .rgb access, so alpha stays readable through .a.

1.2.27 - 2026-05-08

Dynamic MaterialExpression Metadata

• Expression diagnostics accept the Path(...) helper inside UE.CollectionParam(Collection=Path(...), ...) instead of reporting it as an unknown function.

1.2.25 - 2026-04-30

ShaderFunction Properties

• Added completion, diagnostics, symbol listing and visible-variable collection for the ShaderFunction.Properties section.
• Added hover, completion and the constprop snippet for the const property keyword.
• The ShaderFunction snippet now uses the Properties plus opt Texture2D Input = PreviewTex preview-default form.

1.2.24 - 2026-04-30

MaterialAttributes

• Added MaterialAttributes graph type completion, hover and snippets.
• Material Attributes members such as Attrs.BaseColor and Attrs.Roughness are completed.
• Local diagnostics treat Attrs.Member = ... as a member write rather than a new variable name.
• Added Base.MaterialAttributes output binding support in Outputs.

1.2.23 - 2026-04-30

Swizzle

• Supported swizzle diagnostics after a chained call, such as DebugFunction(...).rg.
• Swizzle completion and hover cover 1 to 4 channel combinations, including repeats such as .rrr, .ggg, .aaa, .rgaa and .rgbb.

1.2.20 - 2026-04-29

Language Service

• Added semantic tokens, giving types, variables, parameters, material outputs and UE builtin calls more stable semantic highlighting.
• Added parameter inlay hints for DreamShader Function, ShaderFunction, VirtualFunction and UE.* calls.
• Import paths carry clickable document links; top-level blocks and sections support folding ranges.

• Plugin.MoonToon and Plugins.MoonToon resolve to the same project plugin content root.

1.2.16 - 2026-04-28

Root Completion

• After Root="Plugin.", completes the names of plugins with a Content directory under the current Unreal project's Plugins folder.
• Completion prefers dreamshader.projectRoot from the extension settings, otherwise it detects the project root from the current .dsm / .dsh file and the workspace.

1.2.15 - 2026-04-28

Root Documentation

• Clarified that Root="Plugin.PluginName" points at the project plugin content directory [Project]/Plugins/PluginName/Content.

• Top-level block recognition accepts Name appearing after Root.

1.2.13 - 2026-04-26

Automatic Publishing

• Added an automatic GitHub Actions release workflow.
• On a push to main, the workflow reads the version from package.json and runs npm ci, node --check extension.js and npm run package.
• The workflow creates or reuses the vX.Y.Z tag and uploads the resulting dreamshaderlang-language-support-X.Y.Z.vsix to the matching GitHub Release.
• Manual workflow dispatch is supported, for regenerating a release package for a given version.

1.2.12 - 2026-04-26

Widgets and the Bridge Panel

• DreamShader Bridge moved from the Explorer sidebar to the VSCode bottom panel, so it behaves like the Problems and Output windows.
