I haven't made a "worldbuilder for atmospheres" yet, so you have to write the lua code by yourself. The 3D objects are drawn by using :
- draw_sphere(x, y, z, size)
- draw_box(x, y, z, size_x, size_y, size_z, rot_x, rot_y, rot_z)
- draw_capsule( x, y, z, size_w, size_h, rot_x, rot_y, rot_z)
It sometimes takes very long time to make an atmosphere, and sometimes, you need some skills in maths (example : the dojo ring in Dojo ones, or the fireflies trajectory in Dark Forest). But it's not technically very difficult.
With atmospheres 3.0 it will be a lot easier.
BTW, thanks for your interest !
