Create 3D extruded text

create_text_3d

Create a 3D text scene with adjustable depth, continuous spin, and custom color for title cards or lyric reveals. Outputs a preview and node paths.

Instructions

Build a self-contained 3D text scene: a Text SOP generates the glyph outlines, an Extrude SOP gives them depth (the depth parameter controls depthscale), and a Geometry COMP holds the pipeline with a Constant MAT for colour. A Camera, a Light, and a Render TOP complete the 3D render, output as a Null TOP. Optional continuous Y-axis spin (spin degrees/sec) is driven by a time expression on the Geometry COMP's ry parameter. Exposes Spin and Depth as live knobs. The classic signature look for title cards, lyric reveals, and 3D text drops — use create_kinetic_text instead for flat 2D animated text. Returns a summary plus a JSON block with the container path, created node paths, exposed controls, any node errors, warnings, and an inline preview image.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
nameNoBase name for the self-contained container COMP (default 'text_3d').text_3d
parent_pathNoParent COMP path where the text-3D container is created (default '/project1')./project1
textNoThe text to render in 3D. Use \n for multiple lines.HELLO
depthNoExtrusion depth in geometry units (controls the Extrude SOP's depthscale). 0 = flat polygons, 0.2 = typical title-card look.
spinNoContinuous Y-axis rotation in degrees per second (0 = static). Driven by an expression on the Geometry COMP's ry parameter.
colorNoText material colour as a hex string ('#ffffff' = white). Sets the Constant MAT's colorr/g/b.#ffffff
resolutionNoRender TOP output resolution as [width, height] in pixels (default [1280, 720]).
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=false, destructiveHint=false, openWorldHint=true. The description adds context: internal node creation, exposed knobs (Spin, Depth), and return format (summary + JSON with paths, errors, warnings, preview). This expands on the annotations without contradiction.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is efficient and well-structured. Each sentence contributes essential information, from node pipeline to return format. No redundancy or filler. The distinction from create_kinetic_text is a valuable, concise addition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (7 parameters, no output schema), the description thoroughly covers what nodes are created, which parameters are exposed as knobs, and the exact return structure (summary + JSON with preview). It leaves no significant gaps for an agent to understand invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with descriptions. The description enhances parameter understanding: depth controls 'Extrude SOP's depthscale' with typical values, spin is 'driven by expression on Geometry COMP's ry', and color is explained as setting 'Constant MAT's colorr/g/b'. This adds semantic value beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description precisely states the tool's action: 'Build a self-contained 3D text scene' with specific details on the node pipeline. It explicitly differentiates from the sibling tool create_kinetic_text for flat 2D animated text.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear use cases: 'title cards, lyric reveals, and 3D text drops' and directs to an alternative tool (create_kinetic_text) for flat 2D animated text. However, it does not explicitly state when not to use this tool, so it misses the full 'when-not' guideline.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
