Create 3D models from text prompts

When you do not have an image yet, start with text. Generate a concept fast, then refine with image or multi-view later.

Generate from Text

Sample 3D Showcase: Ice Dragon

Use this sample

Reference Image

Sample 3D Preview

Write one clear prompt with a single subject and style.

Use prompts when the image does not exist yet

This page is built for ideation, not final art direction. Start from a short object-focused prompt, then decide whether the concept is worth pushing further.

Good for internal concept review

Text to 3D helps teams block out a rough object or creature before committing time to a stronger reference workflow.

Continue in the Same 3D Workflow

Text to 3D is a useful starting point when you do not have a reference image yet. Preview the concept, then move to Image to 3D or Texture Generator when you need more visual control.

How it works

Use the tool, preview the output, export only when it looks right

Step 01

Describe one object clearly

Write one clear prompt with a single subject and style.

Step 02

Pick quality and texture

Test with Fast first, then raise quality for better details.

Step 03

Use the output as a draft

Preview and export the result when the concept looks right.

creature ideation

This workflow is useful for creature ideation when you want a faster first 3D draft before manual cleanup or downstream production work.

hard-surface concept drafts

This workflow is useful for hard-surface concept drafts when you want a faster first 3D draft before manual cleanup or downstream production work.

worldbuilding props

This workflow is useful for worldbuilding props when you want a faster first 3D draft before manual cleanup or downstream production work.

quick internal review

This workflow is useful for quick internal review when you want a faster first 3D draft before manual cleanup or downstream production work.

Questions users ask before they spend credits

When should I use Text to 3D instead of Image to 3D?

Use Text to 3D when you do not have a source image yet. Use Image to 3D for tighter control.

What kind of prompt works best?

Short object-focused prompts work best. Avoid long story-like prompts.

Is Text to 3D as controllable as Multi-view?

No. Multi-view gives better shape control when accuracy matters.
