01 January 2011, 05:21 AM
I guys i am working in new production house and we are into our first Product.. I have few questions and i hope to find answers here...

1. Which is the best format to render out files... open EXR or Tiff?
2. What is the added advantage of rendering in 32bit flot compared to normal 8Bit?
3. What are the general passes u need to take for Composition? For Better Composting in Post?

1) OpenEXR. Aside from the 16-bit half float format, it has better compression and is quickly becoming as pervasive as (if not more than) float tiff.

2) It allows you to do more manipulation on the image without introducing artefacts such as banding. Also you can easily represent super-bright values (i.e. values above 1).

3) Depends on what you want to do really. You might want to output individual lights, id mattes to control individual elements in comp, shader sub-passes like diffuse and specular to rebalance the look of your materials etc.
