I am looking for a high overview of the process for texturing levels (or some links to good tutorials). For models I am familiar with UV Mapping and editing to create excellent results (I'm working in Maya). However, with levels the areas textured may be huge. Do quality level designs need to make use of Decals? I have also been researching layered texture shaders to say mix dirt and grass in and out, to create more natural and varied results than one repeating texture. Say for instance I make a detailed flat parking lot. Every parking space has parking lines associated, but I'm confused how I would go about texturing these in, via a decal? Thanks allot for any workflow input.
