Maya LT has the Turtle Renderer which is used to bake out maps. There’s no scene rendering per se, though with the viewport 2.0 that it ships with, the on-screen quality of a textured model is every bit as good as UE4 in-editor rendering. Here is an example of Maya LT 2015 using Substance Materials. Around the 0:30 mark you can see what the default viewport looks like.
And yes, Maya LT has scripting in the form of melscript. There’s a request on the Suggestions site to get Python enabled in LT (it’s there in regular Maya), but no word on that yet.
