There is pretty much only one place you can put a 64x64 lot in the ocean in UC. To place a dive lot from IP here, you can use the following steps:
- Enter the following cheats:
testingcheatsenabled true
enablelotlocking true
SetImportedTerrainOffset -15 (or thereabouts depending on your placement, you can experiment a little, but 15 worked close enough for me)
- Copy a dive lot from IP to the lot bin.
- In UC, use the edit town world editor to place a 64x64 lot in the sea.
- Change the lot type to 'diving spot'
- Go into build/buy on this lot, and flatten terrain to sink it below the water
- Return to edit town and place the lot from the bin.
- Enter the cheat constrainfloorelevation false
- Enter the lot and soften/level the terrain so that it is even around the edges and throughout so that sims can access it
- Drag the hammer tool across the entire lot, then undo. This places objects back on the ground instead of floating/sinking.
- Return to edit town. Make sure the lot is still zoned a diving spot, then save and return to the main menu.
- Open the saved world, and test - you should now (hopefully) have a working EA diving spot!
- To turn off all the cheats
enablelotlocking false
SetImportedTerrainOffset 0
constrainfloorelevation true
testingcheatsenabled false
Note: because of the use of TCE this is not viable for challenges.
