This repository hosts the specification for Scene Layers which are containers for arbitrarily large amounts of geographic data. The delivery and persistence model for Scene Layers, referred to as Indexed 3d Scene Layer (I3S) and Scene Layer Package (SLPK) respectively, are specified.
Like the last issue, there is only one materialDefinitions in a slpk file.
In glTF there is name of every material, but I didn't see that in materialDefinitions.cmn.md, I really can't see how to control each and every node's material and texture.
The materialDefinitions in 3DSceneLayer.json can have more than one materialDefinition object. By adjusting the material property within the nodepage, you can control the material and texture for every node.
