A library for ESD addons and freeware developers containing over 400 Models, Environmentally-Dynamic SimObjects, Visual Effects, Wwise Sounds, and Materials.
Emerald Object Library is a collection of static and dynamic models, materials, Wwise sounds, and VFX produced by Emerald Scenery Design. It allows us to push fixes for common assets across multiple products at once, as well as keep the required space of our addons to a minimum by eliminating duplicates in each project. This library is a dependency of all Emerald Scenery Design addons and must be installed for them to function correctly!
This library may also be used by other developers in their freeware addons. If you are interested in using it as a dependency in your project, please see the Developer Terms of Use section below! Libraries can be found in the scenery editor under Scenery, SimObjects, WorldScripts, and Materials by searching:
Dynamic Features are found under SimObjects and WorldScripts. Please see the included documentation for more information!
Make sure that Microsoft Flight Simulator is not running! Once unzipped, the included "esd-modellib-eolib" folder should be placed into your MSFS "Packages\Community" folder. The library will load the next time you start MSFS!
Always do a clean install to ensure no old files are left behind after each update!
As of June 10, 2021, Emerald Scenery Design authorizes groups and individuals to reference this library package in their freeware creations. The following terms of use apply:
The end-user must obtain this package from an official download source (At emeraldscenerydesign.com, flightsim.to, ORBX, Marketplace, or here on Hangar Addons). Please refrain from packaging it with your add-on or de-compiling it to include partial files for any reason, as it can result in outdated, broken, or conflicting add-ons. Please credit Emerald Scenery Design in your description/documentation by either providing a direct link to the libraries on our site or the URL of our homepage (emeraldscenerydesign.com).
Emerald Object Library is primarily built for and intended to be used with Emerald Scenery Design products. I will add models as I create or acquire them for my projects. Additionally, please be aware that objects may be updated or, in the worst-case scenario, removed altogether. I try to make these changes as seamless as possible by usually replacing objects rather than removing them. However, no notification of these changes will be published, except in the release change log. So, please give it a quick read after each update!
