In Blender it's possible to obtain IBL both in BI and in Cycles, although with different modalities.

Getting ready

Start Blender and load the previously saved Gidiosaurus_3D_layout.blend file; save it as Gidiosaurus_IBL.blend.

How to do it…

We can divide this recipe into two parts: IBL in Cycles and in Blender Internal.
