Texture: As substance has power to generate texture when needed, its size isn't fixed, you can set it.
With substance you can have enormous variations of custom materials.
You can set different values for different materials: overlay textures and color values for body, roughness values for metal, body, wheels.
You can control dirt level, contrast, height, opacity, roughness and generate random dirt pattern too.
Each bike part is separated and pivots are set at correct position, so it's ready for ride.
Can be used for both mobile and desktop devices, but note that currently for platforms: consoles, WSA/WP8, WebGL, Tizen, Unity will pre-render (“bake”) them into ordinary Materials during the build. Although this negates the runtime generation, it is still useful to create variations in the editor.
