Here I will show you how to take further steps in lowering draw calls in Unity3d Game engine by collapsing multiple materials your models may contain into a single material. We will use 3d Studio Max’s UVW tools and render to texture tools to produce and collapse to our models single material.
Here I will be expanding my first tutorial “Unity3d External Lightmap Tool” and show you how to cast object’s shadows onto your terrain. We will setup a 3d studio max that will be your master scene to bake either your terrain light maps or objects light maps.
In this outdoor environment I will be showing you how to both prepare your 3d models for use of the “External Lightmap Tool” and how exactly to use the lightmap tool and achieve almost photo realistic lighting and shadows for your unity3d models.
