Trellis 2 stands out for beginners primarily because of its animation pipeline and lower entry price, but any of these tools can serve as a starting point depending on your specific needs.

Step 1: Visit Trellis 2 and Sign Up

Navigate to https://www.trellis2.art using any modern web browser. The platform works on Chrome, Firefox, Safari, and Edge without requiring any software installation or plugin.

Click the sign-up button and register using your email address or a connected Google account. Trellis 2 runs entirely in the cloud, so there are no hardware requirements on your end. All processing happens on Trellis 2's servers, and your browser handles the interface and 3D preview rendering.

After signing in, you will land on the main dashboard. The interface is divided into three primary areas: the input panel on the left, the preview window in the center, and the settings panel on the right. Take a moment to familiarize yourself with this layout before proceeding.

Step 2: Choose Your Input Method

Trellis 2 offers two primary input methods: text-to-3D and image-to-3D.

Text-to-3D

Click the "Text to 3D" button in the input panel. Enter a descriptive text prompt in the input field. The more specific your prompt, the better the results. Instead of "a chair," try "a wooden dining chair with carved legs and a padded velvet seat cushion in dark green." Include material details, structural information, and stylistic cues where possible.

Example prompts for beginners:

• "A medieval knight helmet with gold trim and a red feather plume, photorealistic style"
• "A low-poly spaceship with blue engine glow and metallic panels"
• "A cartoon cat wearing a wizard hat and holding a wand, anime style"

Image-to-3D

Click the "Image to 3D" button and upload a reference image. Supported formats include JPG and PNG. The image should show the subject from a clear, unobstructed angle. Avoid images with heavy occlusion, extreme perspectives, or poor lighting. Concept art, product photographs, and AI-generated images all work well as references.

Trellis 2 will analyze the image to infer depth, material properties, and back-face geometry. The results are best when the reference image clearly defines the subject's silhouette and surface details.

Step 3: Configure Quality and Style Settings

Once you have entered your prompt or uploaded an image, configure the generation parameters.

Quality Tier Selection

Trellis 2 offers three quality tiers that affect polygon count, texture resolution, and generation time:

Tier	Polygon Count	Texture Resolution	Best Use Case	Credit Cost
Standard	Lower	1K	Prototyping, quick iterations	Low
Pro	Moderate	2K	Portfolio pieces, indie games	Medium
Ultra	High	4K	Production, close-up rendering	High

For beginners, start with Standard or Pro quality. Upgrade to Ultra only when you need high-resolution output for a specific project.

Visual Style Preset

Select from 16 visual style presets. Each preset adjusts the generation pipeline's material shader, texture filtering, and geometric detail parameters. As a beginner, start with "Photorealistic" for realistic outputs, "Anime" for stylized characters, or "Low Poly" for game-ready assets with a deliberate faceted look. You can experiment with other styles like Cyberpunk, Oil Painting, and Cartoon as you become more comfortable.

Step 4: Generate and Preview in 360 Degrees

Click the generate button and wait for Trellis 2 to process your request. Generation time varies by quality tier and model complexity:

• Standard: Typically 30-60 seconds
• Pro: Typically 1-2 minutes
• Ultra: Typically 2-4 minutes

When generation completes, the model appears in the central preview window. Use your mouse or touch input to rotate the view in 360 degrees. Inspect the model from all angles. Check for:

• Overall shape and proportion accuracy
• Texture quality and material appearance
• Any geometry artifacts or unexpected deformations
• Back-face completeness (especially for single-image inputs)

If the result is unsatisfactory, refine your prompt or adjust your settings and try again. Iterative refinement is normal and expected with AI 3D generation.

Step 5: Export Your Model

When you are satisfied with the result, click the export button. Trellis 2 offers four export formats:

Format	Best For
OBJ	Universal compatibility, Blender, Maya
FBX	Game engines (Unity, Unreal), animation pipelines
GLB	Web applications, AR/VR, Three.js
STL	3D printing

Choose OBJ or FBX for most game development and 3D software workflows. Choose GLB for web-based applications. Choose STL if you intend to 3D print the model.

The exported file will be a ZIP archive containing the mesh file, texture maps, and any associated material files. Unzip the archive to access the individual components.

Step 6 (Bonus): Character Animation Workflow

Trellis 2's character animation pipeline is its standout feature. To animate a character:

1. Generate a character model using text-to-3D or image-to-3D.
2. Switch to the "Animation" tab in the interface.
3. Trellis 2 will analyze the model and suggest rigging points based on its topology.
4. Configure basic animation parameters such as walk cycle, idle pose, or custom motion.
5. Preview the animated result in the 360-degree viewer.
6. Export the animated model in FBX format (FBX retains rig and animation data best).

The animation pipeline works best on humanoid and bipedal characters. Quadrupedal or non-standard body shapes may produce less reliable rigging results. For indie game developers, this feature alone can save days of manual rigging work per character.

FAQ

How long does Trellis 2 take to generate a model?
Standard quality takes 30-60 seconds, Pro takes 1-2 minutes, and Ultra takes 2-4 minutes. Generation time also depends on server load and model complexity.

Can I use Trellis 2 on a low-end computer?
Yes. Trellis 2 runs entirely in the cloud through your browser. Any computer with a modern web browser and internet connection can use the platform. No GPU or specialized hardware is needed.

What types of prompts work best for text-to-3D?
Detailed prompts specifying material, structure, style, and color produce the best results. For example, "a ceramic coffee mug with a matte black finish and a wooden handle" works better than "a mug."

Does Trellis 2 support multi-language input?
Yes, Trellis 2 includes multi-language support in the interface. However, English prompts tend to produce the most reliable 3D generation results, particularly for the current version.

Can I iterate on an existing generation?
Yes. You can modify your prompt, adjust quality settings, or change the style preset and regenerate. Trellis 2 supports iterative refinement workflows. Note that each generation consumes credits from your plan.

What is the difference between Standard, Pro, and Ultra quality?
Standard uses lower polygon counts and 1K textures for fast prototyping. Pro uses moderate polygon counts and 2K textures for portfolio-quality work. Ultra uses high polygon counts and 4K textures for production-ready output.

Can I export models for 3D printing?
Yes. STL export format is available for 3D printing workflows. Keep in mind that AI-generated models may require mesh repair or simplification before printing, especially at Standard quality tier. The Ultra tier produces better base geometry for printing.

Do I need 3D modeling experience to use Trellis 2?
No. Trellis 2 is designed for beginners. Text-to-3D generation requires only a written description. Image-to-3D requires only an uploaded image. The animation pipeline is the only feature that benefits from some understanding of 3D rigging concepts.
