This shows my latest planet view with preliminary path finding that shows the connection between complexes. Eventually, this will be replaced by a smooth animation showing a transport flying over the surface, or possibly just some particles.
Each line flows from red to green, identifying which transports are connected. The info on the left shows 5 major inputs, but each input, referred to as a "Transport In Hub" can have many sources, and those sources is what produces all the lines. Looks like this:
Right now the system supports dividing up resources, but does not do load balancing; nor is this planned. If you have a raw material site that produces 375 units, such as the example above, and elsewhere, need silicon, the system evenly divides the available resources up between users. So now, this new complex can get a maximum of 187 units:
Until the player actually makes it a source, the number identified is an estimate based on current information. If they don't select the complex, the other complex still receives 375/hour. If the new complex starts receiving silicon, then the original complex only gets 175; and are furthermore wasting transports.
