As can be seen in the example above you can set a number of parameters to the sosstreamablemodel component:
The path to the streamable asset.
Enable semi-transparent materials
Use PBR shading. Can be set to false if you want flat shading for e.g. photogrammetry models.
Use occlusion culling. This will reduce the amount of rendered triangles and can speed up rendering significantly, but does not work well with shadows.
Path to an equirectangular environment map. Currently only the jpg format is supported. Can be left empty.
Will switch on double sided surfaces in materials.
A number for adjusting the quality level (and bandwidth requirement). Can be any number, but should normally be between 0 and 3. Reference: 0 = low quality 1 = medium quality
2 = high quality
>2 = extremely high quality.
This needs to be set to true if you wish the streamable asset to cast and receive threejs shadows.
