You may have longer load times as result though.
Using scripts to create textures doesn't necessarily mean slow. if we are able to create a texture from a script then we could save that texture same as any. we can create and save textures as they are needed and dispose of them when they are no longer needed. because they are scripts they can be influenced by the game that uses them.
