exrCompression Wavelet Defines the exr compression method to use. All
methods are lossless (with the exception of Pixar 24,
which is lossless but restricts the pixels to 24-bit
float). Wavelet is generally preferable as it offers
~2:1 compression even on grainy data.
exrBitDepth 16 Sets the floating point precision of the rendered exr
file:
• 16 - half float. This is recommended for all color
passes.
• 32 - full float. This is recommended for all ncf data
arbitrary output variables (AOVs).
