TGD:

http://www.bigben.id.au/terragen/files/terrains/nz/While preparing this file I had some unexpected behaviour that I hadn't seen before. Added all of the terrains, and a masking clip for each. While connecting the masks, each connection took longer and longer to complete. Dragging an output connection to an input until it turned green, then releasing the connection.... the line would stay green for a long time (minute or more) before allowing anything else to be done.
Restarting TG would load the TGD OK but after a few edits things slowed right down again. Possibly related to "undo" ? Checked the task manager and CPU usage was maxed out and GDI objects were relatively high (2600+) and slowly climbing. CPU usage and GDI objects would drop occasionally before going back up again. After several cycles of this the line connection would be completed.
Originally had two keyframes with different views (one in orbit, one close to the terrain). Switching between frames would simply stall completely. I was going to run some more tests on this before reporting until others were also experiencing the same problems. My current system has only 1Gb of RAM, and RAM usage of TG was at around the maximum available, although VM was not too high.
Opening the file takes a while with CPU usage maxing out and GDI objects climbing from 250 to 2500, RAM usage aftre preview render completes is only 275Mb.
Tested with my Grand Canyon terrain set and it exhibits similar behaviour. Also has two keyframes, and switching between frames results in the same CPU/GDI objects behaviour.
