Because I am unable to properly get an advanced rig I've created in Maya into Marmoset 1.10 for showcasing the animation of my creature, I am looking at alternative real-time engines for showcasing my work. Does Keyshot qualify as a real-time render engine ideal for game artist in the same way as Marmoset? Any opinions and…
No, Keyshot isn't a real time renderer. Its offline. Marmoset TB2 is one of the best quality engines you get for realtime currently (not least because it doesnt compress textures) but I dont think it supports animation yet. Having said that you could use CE3 or UE4 too, which do support animation.
