When IBL is disabled, materials using KHR_materials_transmission don't do any texture lookup in the opaque pass. So, all transmissive materials appear pitch black when IBL is off.

Spotted in #544 (comment)

To reproduce this, turn off image-based lighting and view any of the transmission samples: AttenuationTest, TransmissionTest, MosquitoInAmber, DragonAttenuation, etc.
