I’m excited to announce that we have recently activated a new feature in Roblox that provides 3 rendering levels of detail for CSG Parts. This improves rendering performance by displaying automatically generated lower resolution representations of CSG Parts depending on their distance from the camera. Currently it is set up to show the lowest resolution at 500 or more studs from the camera, medium resolution between 250 and 500 studs, and highest resolution for anything closer than 250 studs.
Usage of this capability is controlled in Roblox Studio with a new property for CSG Parts called RenderingFidelity. Set this to Automatic in order to activate the Level of Detail feature.
Please let us know if you have any questions.
