Can anyone tell me how much linking multiple project elements and/or having multiple layers affects render times? Basically, my scene starts outside a house; it’s fairly complex with lots of textures, trees, grass, etc. As the camera pulls back, it’s revealed to be a model/display inside a museum.
The “house display” is the most complex element of the scene as a whole. I’ve done as much instancing, material/texture linking, and decimating as I can. The only thing that allows me to even render without a crash is separating the grass/trees/road elements and the house itself into two separate projects, and linking them in another project.
What I’m wondering is whether, say, separating the scene into 5-10 separate projects and linking them together will help or hurt the render? Is there a point at which linking actually hurts the render? And additionally, would placing those linked sections into separate layers help? Is appending a better alternative?
Aside from grouping (which I’m doing to each project element), if I’m missing any render saving methods please let me know. I’m reluctant to do any baking, due to the complexity of the scene and how it looks with camera movement. Insight is much appreciated!
