Error: Unable to read image file "textures/sky.exr": Cannot read image file "textures/sky.exr". No such file or directory.

There are other textures in other directories which I could link to (or copy over) but they might be not the ones shipping with that particular scene:

find .. -name sky.exr -exec ls -lag {} \;
