Hi
my first post!, here goes, thought I would share some work we have been doing recently and that is currently under development, not gone mad with texturing yet, but if you have a read here it will explain what we are doing-

Just thought I would add, we currently have a 3.5 licence, this however was done in Unity 4 demo 
thanks
bad title perhaps, maybe I should have called it ‘7km square 1m resolution multibeam sonar and lidar data in a unity terrain’ !
