Iam using Windows, I-5 processor, 8GB RAM. (BTW I rented this computer to finish this job). These all are I know.
Iam using 3DS MAX, Iam rendering the 3D objects in TGA seq in 4K.
So obviosly all the passes like AO, Reflection, Lighting, ZDepth will be in TGA.
I’d to create some Backgrounds in After effects itself. I render the BGS also first in 4K.
THen I composit all the Shots together, to get final output.
I am not sure if I am giving you enough info to answer my queries.
SO do you say, it is best to use a QT for a proxy and NOT TGA Seq?
