Free Trimsheet Builder Guide
Use the builder when you already have texture maps and want a fast browser-based way to assemble a trim sheet atlas.
- Draw your trim regions first in Layout mode, then switch to Materials mode once the structure is ready.
- Assign one material set per region and keep all maps aligned with shared Fit, Fill, Scale, Offset, and Repeat controls.
- Use the viewport toolbar to review the atlas in Lit mode or inspect each map individually.
- Export one current map or download the full BaseColor, Normal, Roughness, Metallic, AO, and Height pack as a zip.
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.
Free Trimsheet PlannerIs 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.
Free Trimsheet PlannerWhat is the difference between the planner and the builder?
The planner is for marking regions with color intent. The builder is for assigning actual texture maps to each trim region and exporting usable PBR atlas maps.
Free Trimsheet BuilderDo I need to upload all six maps for every region?
No. Missing maps are allowed. The builder fills missing channels with safe defaults so you can still export the whole atlas pack.
