Efficiently use high-quality environments for multiple renders?
I plan on trying this when I get home, but I was hoping to get some discussion on it going before then...
For example, I have "The Enchanted Forest" (beautiful scene, worth every penny even if it was a bit pricey). Unfortunately, rendering takes my machine around 30 minutes with all the shadows and ambient lights, etc.
How convincing would it be if I, say, rendered the scene with just the environment, then delete the environment, but keep the lights, and use the render I just created as a background? I feel like it would be "OK" at best.
Thoughts? Perhaps a gem I haven't heard about that will speed up the render speed?
