This scene was created mainly in 3dsmax and rendered with VRay. All textures are 3DTotal textures without exception, and just to show you how good they are, I decided not to modify any of them, but used each one of them as they came off the discs.
This making of is split into two sections. The first section is a tutorial about making the walls with splines and extrusion, and the second part is the making of The Building scene.
Part 1: Making the walls
This tutorial is for those that are new to spline modeling. What vertices, segments, or a spline can do is fantastic. I start just about every building this way and once the spline is complete, I convert it to a polygon model and I work from there. But, before doing so, I save a copy of the spline/extrusion model, in case something goes wrong later, I can go back quickly and rebuild the wall..
Let's get started, I hope you will not have difficulties to follow this tutorial.
1 - First, turn on the snap toggle (both 2D/3D will do it) and from the Shapes tab select the square tool and draw a rectangle like in the pic below.
2 - Right-click on the line while selected and convert the rectangle to an Editable Spline.
3 - On the right under "Start new shape" uncheck the little box.
4 - Make sure your first large rectangle is still selected and draw a smaller shape inside of it.
5 - Now go to the Edit panel and select Segment mode.
