I can't find info on how to achieve this. I'd like to make n64 style graphics and imitating the way models and environments are "lit" is the part I'm very lost on. I've heard it's a kind of vertex shading but I'm not sure how to do this, in blender specifically and accurately to how it looks on n64.
One example of what I mean is seen very well in pokemon stadium:
And a more dramatic(and nice looking) example is bongo bongo from Ocarina of Time:
This is not how the actual model looks obviously, as there is lighting effects added for the game. How can this style of shading and lighting be imitated in blender?
Edit: In addition to manually painting vertexes for certain lighting effects, I also found some sources that say that the N64 used gouraud shading, but I can't for the life of me find any information on how to render something in blender with such shading. Any help?
