have better graphics

In general great game-like graphics requires lots of artist work. We could expose shaders or give more material control to enable better graphics but this will require lots of artist and programing work from a Flow user. If you want to develop code than there are game engines out there. Flow supports dynamic lighting, diffuse and specular maps, dynamic shadows, ambient lighting and ambient occlusion baked into lightmaps. This allows for good quality and still does not require lots of detailed knowledge about 3D graphics to have something working and looking nice. Its about showing your ideas in 3D and making it easy not about spending countless hours to make something look real life like.
