The courses look great Sage! I'm still amazed at how fast you can paint a terrain with the course textures!
I agree with Ian, seam blends are what cause the save times to be so long. It doesn't take many to cause a 5 min wait at saving. With the courses I am working on now, my plan is to get the seam blend areas ready and textured but wait until planted is finished before mapping the seam blends. The high number of verts does not impact save times, only the BSP tree calculation the APCD does when switching to planting after the terrain has been altered (or at V&S after terrain edits). Like many added APCD 1.5 features, seam blending seems to be poorly implemented within the program. It is almost as if the APCD has to recalculate everything for the path mappings when saving.
Sage, something I have noticed with your courses for a long time is the geometry for the seam blends. I can only get simple "cart path" geometry for seam blends to map properly. I have tried mapping a seam blend to areas with internal verts and I ended up with a corrupted course file. If it was me I couldn't get the geometry pictured below to even path map, and yet your courses always contain seam blends with this sort of geometry. My assumption is that the seam blends with "non standard" geometry are causing the extra long save times. Anyone have any thoughts on this?

Danny D - Sage wanted more clarity of the bunker detail to get all those edges done properly so I tried breaking the plot into 4 quadrants and provided a 4096x4096 texture for each. It is more work but looks like it is well worth it. I started doing some of my plots with multiple textures and for courses with jagged bunker edges it helps a lot! Only issue I have noticed is that APCD can only handle 1 4096 texture active on the terrain. I think some of my crashes were attributed to having a couple 4096 textures on the terrain.
