For example, when I run "oiiotool -help", I get something like this at the
end:
Known color spaces: "lnf" (linear), "lnh", "lnzf", "ln16", "lnz16",
"lg16", "lg10", "lg8", "lgf", "gn16", "gn10", "gn8", "gnf", "rclg16",
"rclg10", "rclg8", "rclgf", "lgc10", "vd16", "vd10", "vd8", "telecine8",
"vdf", "hd10", "dt8", "dt16", "cpf", "nc8", "nc10", "nc16", "nch",
"ncf",
"qt8", "srgb8", "p3dci8", "xyz16"
Known looks: "cc", "di"
Known displays: "DLP" (views: "Raw", "Log", "Film"*, "Film CC", "Film
DI"), "sRGB"* (views: "Raw", "Log", "Film"*, "Film CC", "Film DI") (* =
default)
It's behaving as if it is not seeing your OCIO configuration. So maybe your
$OCIO environment variable is not set to point to the config.ocio file?
