# Line 1975 | Line 1975 | Added default specular lobe to BSDF interpolation.

1978 +
1979 + ****** COMPATIBILITY CHANGE ********
1980 + Made header input and output the default behavior for dctimestep and
1981 + genskyvec.
1982 +
1983 + ****** COMPATIBILITY CHANGE ********
1984 + Changed pabopto2bsdf default behavior to add 90-degree rotation
1985 + to bring pgII's definition of "up" in line with Klems axis
1986 + conventions.  Introduced a new header variable "upphi" to
1987 + control this added rotation.  Using "#upphi 90" in each
1988 + BSDF input file gets back the original behavior, where it
1989 + assumes that the up direction is 90-degrees from the X-axis.
1990 + The default value of 0 corresponds to PAB's definition of
1991 + the X-axis as being "up".
