I have a few questions about World Partitioning and Data Layers. To give some context, I have an indoor scene with approximately 4200 items in it. The level has 5 different floors. I currently have the entire level set using world partitioning. My question has to do with performance. Would it make sense to make each floor a data layer in addition to World Partitioning? My understanding is that using data layers reduces memory footprint, is this ram or vram? And finally, can data layers work with world partitioning and not conflict with each other?
Yes you can set up the items on different floors in different data layers. This will make you able to load in and out the layers to save memory.
You could also set up something that is called Cull Distance Volumes. By adding parameters to them you can basically unload really small objects that you wont see from for example a five meters away.
Thanks for the response. Is this memory system ram, vram or both? I ask because I am running low on vram and I am trying to create more of a buffer zone without having compress the textures too much.
