VisualShaderNodeCustom

public bool Initialized { get; set; }

Internal editor-element initialization flag. Do not use it as evidence of GPU compilation or material readiness. When true, ordinary custom-node input-default mutation methods are restricted.

public string Properties { get; set; }

Internal serialized dropdown-selection data. Declare choices through _GetProperty*() and read selections through GetOptionIndex(); do not construct this string manually.

public int GetOptionIndex(int option);

Read a stored dropdown selection for code generation. If no value is stored for that setting, the native implementation returns 0.

public virtual string _GetCategory();

Set the custom block category path, for example Reckfell/Color. The editor adds an Addons prefix; / separates subcategories. Do not apply block-name restrictions to the entire path.

public virtual string _GetCode(Reckfell.Collections.Array<string> inputVars, Reckfell.Collections.Array<string> outputVars, Shader.Mode mode, VisualShader.Type type);

Return Reckfell shader-language statements for one block instance. Use inputVars expressions and assign results to outputVars; port labels are not substitutes for these strings. Do not redeclare a shared function in every instance.

public virtual int _GetDefaultInputPort(VisualShaderNode.PortType type);

Choose an input when creating a block by dragging a connection into empty graph space. Return a suitable index for the supplied type. The 1.0.0 native fallback returns 0 when not overridden.

public virtual string _GetDescription();

Set the block description in the add dialog. Briefly state the operation, ranges and mode limitations.

public virtual string _GetFuncCode(Shader.Mode mode, VisualShader.Type type);

Add shared code at the beginning of shader functions for this block type. Insertion order across different custom types is unspecified; do not depend on that order.

public virtual string _GetGlobalCode(Shader.Mode mode);

Add shared declarations outside shader functions. The generator emits them once per used C# script, even with several instances. Use unique names and do not store instance-specific state here.

public virtual int _GetInputPortCount();

Declare the number of input ports. Name, type and default callbacks receive indices from 0 through this count minus one.

public virtual Variant _GetInputPortDefaultValue(int port);

Return an initial value for an unconnected input. The editor applies this callback when inserting through its UI. In 1.0.0, programmatic VisualShader.AddNode() does not write these defaults: explicitly call SetInputPortDefaultValue() after adding.

public virtual string _GetInputPortName(int port);

Set an input port label. This is not a ready-to-use GPU variable name: use the supplied inputVars[port] expression in _GetCode().

public virtual VisualShaderNode.PortType _GetInputPortType(int port);

Declare an input data type. Keep its default and shader expressions consistent; Vector3D corresponds to vec3 and Scalar to float.

public virtual string _GetName();

Set the block name in the add dialog and graph. Editor registration requires a valid ASCII identifier without spaces, such as BlendTint.

public virtual int _GetOutputPortCount();

Declare the number of output ports. Assign each calculated output in _GetCode().

public virtual string _GetOutputPortName(int port);

Set an output port label. Assign to outputVars[port] in _GetCode(), not to the label string.

public virtual VisualShaderNode.PortType _GetOutputPortType(int port);

Declare an output data type; its generated assignment must produce a compatible value.

public virtual int _GetPropertyCount();

Declare the number of dropdown settings on the custom block; this is not the input port count. Supply each setting name, option list and, when needed, default index.

public virtual int _GetPropertyDefaultIndex(int index);

Declare the initial selected index of a dropdown setting. It must match the array returned by _GetPropertyOptions().

public virtual string _GetPropertyName(int index);

Set a block dropdown setting label.

public virtual string[] _GetPropertyOptions(int index);

Declare the ordered choices of a dropdown setting. Read its selected index through GetOptionIndex().

public virtual VisualShaderNode.PortType _GetReturnIconType();

Choose the result-type icon in the add dialog. This is UI metadata; _GetOutputPortType() defines actual output types.

public virtual bool _IsAvailable(Shader.Mode mode, VisualShader.Type type);

Filter block availability by shader mode and graph stage; true by default. This does not translate shader code between modes or prove GPU compatibility.

public virtual bool _IsHighend();

Mark the block as requiring Forward+ or Mobile features in the add dialog. The default is false. This is editor guidance, not a renderer switch or a substitute for checking GPU code.
