Control (UI) Default Value Function

exrCompression Scanline ZIP Defines the exr compression method to use. All methods are

lossless (with the exception of Pixar24, which is lossless but

quantisizes 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).

exrOptimize Yes When enabled, the exr file is written out in an a manner

optimized for efficient random tile-access. These optimizations

greatly improve memory usage and performance for programs

which process images in tiles.

exrType Tiled Sets whether the exr file is written to support:

• Tiled - random tile access.

• Scanline - random scanline access.

clampOutput No When set to Yes, post-render clamp negative rgb values to 0,

and clamp alpha values to 0-1.

Note: clampOutout has no effect on NaN and inf values.

colorConvert Yes When set to Yes, post-render convert rendered image data

from linear to the output colorspace specified in the filename.

The default value of Yes is suitable for nearly every situation,

since the linear output of the render will be converted to the

colorspace in the filename. A case where you would want to set

this to No is if you know the data being rendered is in a

colorspace other than linear, such as the reprojection of a log

plate, and you want to name the output file log without a linear

to log conversion.
