[Radiance-general] mirror material ignoring modifier in virtual source calculations

[Greg Ward]

You are both correct.  Applying the original modifier to the alias works, as does using the "inherit" tag.  One of the purposes of alias'es is to "pull out" a material (or modifier) definition to use with (or within) a different modifier chain.  The "inherit" tag was added later on to simplify alias management when all you wanted to do was essentially reassign materials.  If that's what you want alias'es for, then just get in the habit of using "inherit" in your work.

Cheers,

It now makes sense, but I wonder if it would just be easier if aliases could inherit modifiers, unless Greg thinks it is not appropriate. I would personally think it would be more intuitive.
