I have a 3D frog model that I'm trying to properly light up. I have not applied any lighting effects to the model in Blender. In my project, I'm using a BakedLightMap node to light the scene. When I have frog models in my game, the lighting seems to be only applied to some triangles, and not to the whole model. Here's a screenshot of the model:
I used the better COLLADA plugin to export it, and I used mostly default options (used the "export animations" option), so I don't entirely know what could be causing this.
