FAQ

What is a trim sheet?

A trim sheet (or texture atlas) is a single texture that contains multiple tileable material strips. 3D artists UV-map different parts of a model to different strips, reusing one texture across many surfaces for efficient rendering.

Is this tool really free?

Yes. The planner runs entirely in your browser with no signup, no upload, and no API calls. Download your trimsheet PNG for free.

Can I generate AI textures from this layout?

Yes. Use the same workflow in the full TrimSheetFast texturing tool to add descriptions per marker and generate PBR-ready textures with AI.
