That's what I said, it's not a render engine :P

Can you have custom light ? (planar, point, sphere, linear)
Surface description ? (glass, metal, SSS, emitter)
Do you have any GI solution ?
Can you do caustics ? Render hair of fur ?

I's not because there is a render button that you can actually say that 3DCoat is render engine.

Give to MoI a quick shadow pass and you have probably something similar.
