Landscape area - plant filling / numbers mystery

[DSmith2300]

Hello,

 

I seem to have having a mystery issue with landscape areas not filling with plants.

See attached screengrab. This blank areas varies as to plant spacing.  If I show plants in 2D and hit 'random plant placement' then it fills up. 

But what If I don't want to show the graphics? And how can I be sure that the count is correct? 

 

OK Well two things.

The other is I do not seem to understand the logic of how the plant numbers are calculated within landscape areas.

 

For instance if I want 2 species at 5pm² then they spread out ok and evenly. If I wish a third larger species to be placed within that mix at say .25pm² (1 per 4m² ) then it decides that there's no room and I'll only get 2 plants of that third species even though there's 182m² to play with.

I guess that I could just overlay loose plant symbols onto the landscape area, but that seems to defeat the purpose of the system.

 

Currently reviewing VW university videos to try and understand spacing logic.

 

Thanks for any help.
