The raytracer does not support derivatives for filtering through reflections, so normal maps do not work.

This is so frustrating! It's holding my project back... if I knew code, I'd be fixing this right now...

Basically, you simply can't see a bump map through a transparent raytraced object.

Hi brecht,

I gave ton some code to fix this. Have you guys tried it yet?
I think ton was saying it's on his list of things to look into soon.

Morten: I didn't see any patch for this yet.
