This was one of my favourite pieces to make, really viscous, wet, fleshy and odd sense of scale, which is the resulting manifestation of Josh's mind. He was messed up! and all his fears appear in front of him through this horrific womb like scene.
I used a vein detail map inc Base Colour, Normal and Roughness on top of the zbrush sculpt to get the extra veiny detail on top.
Once again all in Killzone Engine in the custom Maya deferred renderer.
