Foundation Kit - Sci-fi modular building system Version 3.0

The Greeble Foundation Kit is an efficient and low-impact modular sci-fi kit designed to be easily modifiable for use in various futuristic builds as gantries, catwalks, scaffolding & platforms.
A number of ready-to-use pre-built structures are also included to both demonstrate what the kit is capable of, and to save time.
The Foundation Kit is designed around a 4x4x4 metre cubic grid. This size was chosen due to several factors, including Second Life's parcel sizes, and the need for flexibility of rotation.

PLEASE NOTE that this product is also included bundled inside some Greeble products.
Some familiarity and understanding with building and modding is recommended to make full use of Greeble products.

FAQ/Notes

Modding
Most of the components in the Foundation kit have been designed to be easily modifiable inworld. The textures are typically pale and neutral-toned in order to be best tinted inworld. The faces of most of the meshes have also been UVed in such a way that the textures can be replaced and adjusted by users inworld without too much issue.

Technical Specs:

Permissions: ✅Modify, ✅Copy, ❎Transfer (The scripts are no modify)
Shading Model: Physically Based Rendering, with Blinn Phong fallbacks
Linkset Accounting Model: Current (Land Impact)

Version Notes:

Aug2025 - 3.0 Release
- Complete overhaul of all textures from Blinn Phong to PBR. The PBR materials are now included (mod/copy/no-transfer). All objects should have correct fallback materials.
- New components, including rooms, corridors, plates, gantries, lights.
- All objects now have inventory thumbnails. This should allow for easier browsing when trying to find that specific component.
- Rebuilt pre-built structures with new components, materials & reflection probes.
- With PBR materials being included, some redundant components have been removed as they were simple retextures which should now be possible by the user.
- The Gantry & Pre-assembled components categories have been merged. Some redundant individual objects have been removed, these still exist in the f-kit, but as part of pre-assembled component linksets.
- The adjustable script in some components has been removed, as it does not currently work with PBR materials, we hope to reintroduce this at a future date if it becomes functional again.
Nov2023 - 1.1 Release.
- Rebranded from Gantry System to Foundation Kit (F-Kit).
- Added numerous components, including rooms, corridors, plates & doors.
