I am trying to render a large scene using the blender cycles render engine. The scene itself exceeds my gpu(s) ram limit. For this reason i am gonna try to split the scene up using either scenes or layers, so that i could render each element seperatelly.
My question is:
Which should i use layers or scenes?
I have created a test .blend file so that i could play around with compositing 3 different movie clips together. Sadly my attempts creates transparency issues, the composite also appears white washed.
How do I go about resolving this?
My actual project would be rendered in cycles, so far the renders produces out memory errors, i.e. my GTX 560 ti(448)+gtx 550 which are both only 1gig cards.
How would i go about optimizing my scenes for GPU rendering without spending a dime.
