Max number of lights renderable per object. This is further limited by hardware support. Setting this low will slightly reduce memory usage, may decrease shader compile times, and may result in faster rendering on low-end, mobile, or web devices.
|

Max number of omnilights and spotlights renderable per object. At the default value of 8, this means that each surface can be affected by up to 8 omnilights and 8 spotlights. This is further limited by hardware support and [member rendering/limits/opengl/max_renderable_lights]. Setting this low will slightly reduce memory usage, may decrease shader compile times, and may result in faster rendering on low-end, mobile, or web devices.

|

Max amount of elements renderable in a frame. If more elements than this are visible per frame, they will not be drawn. Keep in mind elements refer to mesh surfaces and not meshes themselves. Setting this low will slightly reduce memory usage and may decrease shader compile times, particularly on web. For most uses, the default value is suitable, but consider lowering as much as possible on web export.
