This is my first game scene in Unity with the intention of exporting it to Sketchfab.
The scene has two point fill lights, a sky portal, and one main directional light with a cookie that casts shadows like light breaking through trees.
The simple diorama of models were made in Blender then assembled in Unity. I did it this way because of a comment I read here by Glenotron on the creation of his pirate ship - "... lighting/baking in Unity (I prefer the tools), then saving out the .exr lightmap as a .png, so I can use it elsewhere".
The unity scene screen shots (below) show simple Unity materials on all objects (some unfinished) except the backdrop (and ceiling) which uses an 'Unlit' shader so that it doesn't recieve shadows from the trees.
All advice welcome. Thanks.
