Start from a completed asset
Open a ready model in your workspace. In its edit field, describe the difference you want: “Make the horns shorter and change the eyes to green.” Focus on a small number of specific, visible changes rather than rewriting the whole original prompt.
Compare the new result
Submitting an edit starts a new asynchronous generation task. When it completes, you get a separate asset; your source model remains available. Preview both before choosing which one to download. Edits use the existing model as input, but are not guaranteed to preserve every cube or material exactly.
Know the boundary
This edits static model geometry and appearance. It does not create or save animation keyframes. Each edit counts as a generation request for rate and concurrent-task limits. For precise cube or texture adjustments, download the .bbmodel and refine it in Blockbench.
