I'm not vary good at modding, so I was wondering is there a premade height map of Cyrodiil out for Skyrim. Also Does anyone have some meshes from Oblivion. I wanted to make a hybrid Skyrim/Oblivion achitecture Island mod.(with an Ayleid ruin. Sorry but I'm but I'm new to the modding scene and didn't understand how to convert Height maps/meshes to Skyrim. Any information on how to do this will also help me.
I'm not sure about the heightmap. If you want the Oblivion meshes, just go to your /Oblivion/Data/ and there will be a Oblivion-meshes.bsa file and use a bsa archive extractor to extract it. Those won't work with Skyrim, just Oblivion. It sounds like you want to make the island for Skyrim but in the Oblivion landscape? I'm not entirely sure how to do that, or if it's possible.
If as unknownone has stated,you want your island in the skyrim engine,but with oblivion meshes,?,you would have to create your island in the skyrim CK,then convert the oblivion meshes to skyrim format etc.
The other way around you would need to use the oblivion CS to make your island,but I think you want an oblivion height map in skrim,? [not possible].
And you would need a lot of time on your hands as it could take a while.
