Hi there! Excellent tutorial. It took me forever to get through (seriously, multiple days), but all the problems I had inevitably stemmed from me simply not reading the directions closely enough.
Now that I've come to the next step in the process for me, importing the snowman I made into Unity, I'm having a small but frustrating problem with light and shading. Obviously this isn't within the scope of the tutorial, but I thought someone might be able to help with the issue.
I exported the model as a .fbx, and imported into Unity. At first, the entire model was inside out (that is, the textures were only rendering on the inside of the model, giving it a weird concave look). After some looking around, I discovered that the normals of the mesh needed to be reversed. I did this in Blender and reimported it into Unity ... problem solved!
Except, the lighting was wrong. The model is showing light on the opposite side from where the light source is. As I move the directional light in Unity around, the problem persists - horizontally and vertically.
I've searched around quite a bit for solutions to this online, and I've not found a solution. I have made sure to play with the model import settings in Unity, setting the normals and tangents to import, but no luck so far.
Any help is appreciated! Thank you!
