Level design was one of my core module in Ngee Ann Polytechnic. Hence, I have design both indoor and outdoor environments in Unity. Most of the environmental assets for the levels were modelled in Autodesk Maya. The first level is medieval roundtable chambers. Hence, the lighting was baked into the environment and most of the environmental effects such as flames were done with Unity's Particle Effects system. The second level is an waterfall environment. Likewise, most the environmental effects were modelled with Autodesk Maya. The waterfall drop and ripples were done Unity's VFX. Here are some of my  videos walkthrough below:
