Camera position, Lighting and More

We have custom template files with among other things camera position and lighting specs preset available for (software) Blender, 3ds Max 3D Studio Max and 3D Lightwave. Ben Robbins has made a 3DSMax template and Aracirion a Lightwave template. You can pm them for details on each. For Blender, download version F, the new contrast version. Before using them, please read through the short blurbs below.

Sizes

In maximum zoom level one square equals 12,5 m x 12,5 m equals 64px across. This is the basic unit for railway tracks and roads. As the buildings in the original Transport Tycoon look as if they are about 25 m x 25 m per square, many new buildings will occupy 2 x 2 new 12,5 m squares. For scale comparison Ben Robbins modelled Ottis, a real-size human.

Materials

For every material you create, in the shaders tab, you are advised to change the Amb parameter (0.5 by default) to match the Ref parameter (1 by default). You always have to modify Ref and Amb together. It has been decided that Amb should always have the same value as Ref, because a material should reflect light from the sun or other light sources the same way it reflects light from the environment (ambient light). Hence, for maximum realism, the values should be the same. Naturally this is not a strict rule, you do have artistic freedom to deviate from this.
