Add ShaderGraph.IsSubgraph and add "Shader Sub-Graph" to the New Asset menu Shader Sub-Graphs are now saved with the `.shdrfunc` file extension despite being the same asset (just so it can be registered with a different icon and filtered against in the Asset Browser to reduce user confusion) Give .shader, .shdrgrph, and .shdrfunc assets different colours in the Asset Browser Don't include BlendMode, ShadingModel or Domain in Subgraphs Don't include "Material" ShaderNode in the Create Node/Palette menus of Subgraphs. Ensure proper extensions are used when opening the respective file types. Add PlugInfo and make BaseNode.Inputs and BaseNode.Ouputs virtual. Added FunctionResult ShaderNode, can only be created in Subgraphs and is created as the default node in newly created Subgraphs Fix Shader Graph wanting to save/load as sub-graphs Make sure [Title] attributes are still respected with PlugInfo FunctionResult can now have a variable amount of inputs of varying types defined by a Dictionary. These are to be used as the outputs of the eventual sub-graph node Use shader-specific types for FunctionResult Inputs https://files.facepunch.com/CarsonKompon/2025/January/16_16-02-HumiliatingMorayeel.png Rename "Inputs" -> "Outputs" on FunctionResult since that's technically more accurate Instantly update the Result node when Outputs are modified https://files.facepunch.com/CarsonKompon/2025/January/16_16-18-WarmIncatern.mp4 FunctionResult node will produce Errors preventing compilation https://files.facepunch.com/CarsonKompon/2025/January/16_16-48-VictoriousBrownbutterfly.png Fix NRE when attempting to save with unresolved errors Guarantee IsSubgraph is set properly from the ShaderGraph window Only Update FunctionResult.Inputs when necessary instead of when accessed. Add PlugInfo.GetInput() and serialize PlugInfo.Name as the property name instead of display name Fixed NRE when FunctionResult name is left null Subgraphs no longer attempt to generate a .shader file, and will run error checks in the graph on Save FunctionResult Inputs now maintain connections upon being regenerated FunctionResult node generates inputs before creating connections to ensure connections are always deserialized correctly PlugInfo correctly uses property name if no [Title] attribute Refactor Result node into an abstract BaseResult class which Result and now FunctionResult can both inherit You can now specify the preview type for certain Output variables on a Subgraph so changes can be reflected in the Preview window. https://files.facepunch.com/CarsonKompon/2025/January/21_12-51-DifferentAmericanbulldog.mp4 Can change Preview Blend Mode/Shading Model/Domain in Subgraphs Implemented all other preview types for FunctionResult Fix GraphCompiler failing when using Unlit in Subgraphs Subgraphs have Title, Description, Category, Icon and Add To Node Library properties. To be used for the created node Added SubgraphNode which references a .shdrfunc. Results in graph errors if the references graph cannot be found or the references graph has errors Dragging a .shdrfunc asset into a ShaderGraph will create a Subgraph Node referencing the dragged asset Fix error when deserializing SubgraphNodes SubgraphNode now uses the Title, Description, and Icon from the referenced Subgraph SubgraphNode now generates inputs from any Parameter nodes in the subgraph, with default names for any without. SubgraphNodes now generate output plugs from the FunctionResult node in the references Subgraph https://files.facepunch.com/CarsonKompon/2025/January/21_16-23-CoordinatedEastsiberianlaika.png Subgraph "Add To Node Library" adds the subgraph to the Create Node menu so they can be easily accessed. https://files.facepunch.com/CarsonKompon/2025/January/21_16-51-HardVampirebat.mp4 Double Clicking a Subgraph Node instantly opens the Subgraph Implemented the file history forward and back buttons when navigating through multiple ShaderGraphs in the same window https://files.facepunch.com/CarsonKompon/2025/January/21_18-29-MidnightblueSandbarshark.mp4 Add [Hide] to TextureCoord.Title override Minor MainWindow refactor so .shdrgrph files arent recognized as Sub-Graphs mistakenly Prompt to save current graph (if dirty) when pressing the Forward/Back/Home buttons Created ITextureParameterNode and started custom inpsector editor for when texture samplers are present
