Rendering a 3D volume I'm playing around with ways to visualize an MRI image of my head. I've extracted my brain, so there are non-zero brain voxels in the center, and zeros to the edge of the image.

I'm imagining having a corner cut out of my brain to expose its interior voxels like this: 

Additionally, I've also got voxel-wise statistical data that I'd like to use as a semi-transparent overlay on the anatomical.

Is this setup possible?
Here's my BI setup:

material:



textures:



The first texture is a nice dense whole brain object, almost making the voxel data appear like a surface. The second texture makes the voxel values affect reflection color, which is important for inside the object.

I used a simple boolean modified to cut away the corner chunk:
