The shot above is WIP so let me explane;
Dirt: Dirt is probably the last Detail I add to a scene. Once a scene/corridor is finished and I have the right texture for it I will add dirt either to the Texture itself or by decals.
Orange Light: This should be like an emergency light you know. Yes the model is still missing, all my tries to create one ended up pretty ugly

By now, the scene improved already a bit, maybe I will post a Screenshot today if you guys want

@PadMalcom: a month ago somewhere I found a more easy curve method than Bezier, where all the defining points are on the curve, so it handles better the endpoints. it is called as Catmull-Rom spline, and has functions in DirectX, available in 3DGS d3d9.h, as D3DXVec2CatmullRom, D3DXVec3CatmullRom, and D3DXVec4CatmullRom. (I planned to use it but finally made a more basic solution)

Hey sivan, great information, thank you! The advantage of catmull is, as you said, that it goes through ALL points on the track which is really useful to me.

@PadMalcom
You should think about finding points in your voronoi net that are close to each other and weld them to create intersections or roundabouts (for 5 or more connecting roads)

@Marius: Yes I know I already implemented a variable in my voronoi generator to define a minimal distance between intersections... but I didn't use it yet

EDIT: @Sivan: I found it quite difficult to calculate the position value of the Catmull. It is not only going from 0 to 1.0 but has to be set individually for all ways.

I'll try to get a more usable source in connection with catmull, I remember I read a good one somewhere, that might help...

It is okay, I found out how to use it

Thanks anyway!

Why is Lotti all of sudden so much AAA? ^^ Nice effects!

Last update (for now) on the Basement, hope you guys like it.
