I am making a Nintendo 64/ PS1 inspired game in Unity. I know that those consoles did not have lighting and instead used vertex colors on textured models to add variations in light and in color to save on space. Like Banjo-Kazooie, TLOZ: Ocarina of Time, Spyro, etc.
Here is another example: https://twitter.com/JasperRLZ/status/1094624131012714498
I would like to use this technique in my level models and then export them to Unity, but I can't find a way of doing it. The best I could find is this video, but it doesn't work for me when I do it, and it does not explain much of what they are doing: https://www.youtube.com/watch?v=0VEdMQIF_sU If anyone knows how to do this, please do tell. Thanks!
