Area to cover is 20 sectors, a single 2k shadow map (orthographic top-down) has a sampling step size of 20*1024/2048=10 units, seems enough. General idea is to build an orthographic top-down depth texture only containing dynamic items. Rendering will probably need multisampling for blurring the shadow map.
Need to add CSM, because the shadow volume is quite large.
Modernize old bbox shadows.
