I'd like to know what your technique for creating 2d scenes are? Because all I'm good at is pixel art but would like to turn my sketchup rooms and photoshop it to look cartoonish as iv seen some people do it. Yet I have no idea how and haven't found tutorials while searching the internet.
Cartoony? Well, I know that some cartoony games will exaggerate features, such as crazy doors that don't have straight lines.
And a brick wall would just have a few bricks in it, rather than a heavily detailed brick by brick texture.
That's all I have..
I think that what you're looking for is a toon shader or a cel-shader. You use them in a 3D modelling program to render a 3D modell to look like a 2D drawing. I don't really know that much about that, but maybe having a name for this function can help you to continue your search. :)
