When I invoke mkillum either via rad, or directly, I receive path errors:
mkillum -ab 0 -ad 1024 -av 10 10 10 testrad2.oct “<” glass1.rad glass2.rad > glass.rad
mkillum: system - cannot find function file “~matthews/materials/wobbly_tile.cal”
At first it was looking for ‘oakfloor.pic’, when I copied ‘oakfloor.hdr’ to ‘oakfloor.pic’ that error went away to be replaced by the new one above. All else is working fine. I’m running Radiance 5R2 on a Mac running Catalina. I compiled Radiance using Xcode, and run it under XQuartz.
Sorry for asking what I hope is a silly question.
