And also some quick tutorial would be nice
you must specified much more, than i will help. We havn´t time to write down a good tutorial (remember, we start at june 2008 and no track is done). Maybe at the end we worked fore waste, because we are not understand right the technique of softshadow (only wally can do). Some other parts are not complete clear, so we can only help for special questions. At the moment i help delu77, how i can. At some parts, i don´t remember complete, we test many things of it in autum last year. Maybe you can ask delu77, he test actualy something.
For good texture, you need a good base texture and many knowledge of Photoshop. there is wixi the crack
.
Much of the the good track are good textures (they are difference from others). We will not publish special objects (houses or so on). On inquiry we will give some more, but with condition to change the look. It makes no sense, if special german objects or other textures will be used for example a australian track. Please understand.
You can ask all here in the forum, i look many times daily in to it. But i can only help for RBR trackbuilding souroundings, 3dsmax,some about photoshop and some about wallaby. BTB is not my part (maybe in the future).
