Recommended test
Generate a textured building and check each sheathing category before and after reopening.
- Confirm Textures is on in the Build Generator header, then select OSB roof sheathing and a chipboard floor.
- Generate, use a textured display style, and hide roofing and wall siding to expose the sheathing.
- Check OSB on roof panels, Asfaltplate on wall panels, Chipboard Light on the floor and Spruce Light on framing.
- Add a door or window with Opening Framer and confirm its new timber uses Spruce Light while the sheathing retains its own textures.
- Save the .strek file and reopen it in a fresh session to confirm the generated assignments return.
- Generate a separate example with Textures disabled and confirm these defaults are not applied.
- Check a hip-roof garage: the roof and drainage keep their grey finishes, foundation walls use concrete, and timber bottom plates use spruce.

Use generated textures
Textures starts enabled for new visual-builder designs and Default building. Saved designs and presets keep their own choice. Use the header button to turn textures on or off, and select OSB in the roof’s Advanced settings. Choose Generate building, review the design, then Build now. In a textured display style, hide roof covering or wall siding to see the panels beneath them.
| Generated part | Default texture |
|---|---|
| OSB roof sheathing | OSB image |
| Wall sheathing | Asfaltplate image |
| Chipboard subfloor | Chipboard Light |
| Timber framing | Spruce Light |
| Foundation walls, including pieces beside doors | Concrete texture |
Timber bottom plates above the foundation remain spruce, including plates cut around doors. Hip roofing, flashing, gutters, hooks and downpipes keep the same grey finishes as the other roof types. Fascia and other timber trim retain wood. Regenerate an older affected design to apply these assignments; loading existing geometry does not rebuild its finishes.
OSB selection applies to gable, skillion and hip roof sheathing. Generated dormer wall and roof sheathing use the same corresponding assignments. Other roof sheathing materials keep their existing defaults.
Appearance and project saving
Textures change appearance, not material labels, dimensions or quantities. The OSB and Asfaltplate images are optimized JPEGs for faster loading. With Textures disabled, these generated defaults are not applied.
Save and reopen a textured Build Generator project to retain its generated assignments. The applied model base texture is restored before the sheathing-specific textures, so an OSB or wall-sheet selection does not spread over all the framing.
To apply the new defaults to an older design, save a baseline and regenerate it. For painting individual parts and adjusting scale, see Apply and paint model textures.
New opening framing
New timber created by Opening Framer uses the building’s base texture, Spruce Light by default. Automatic OSB and Asfaltplate assignments leave the selected paint texture alone. Choosing a brush for painting individual parts does not change the texture of newly created opening framing. With generated textures off, new framing stays untextured.
