With RFTools Dimensions disabled, and Nether being a void, are there any exploration options?
No it's a traditional skyblock. The idea is that you build in an almost void world.
However I think you know that and this question is probably rehtorical.
The exploration aspect of skyblocks tends to be seriously lacking.
I'd like to one day see a skyblock that isn't so void. More of a sky island pack. None of this sifting nonsense. But actual world gen woth ore and maybe even dungeons
You'd have your start island with the tree, the water and your lava source. But you'd have in the distance sparce but sizeable chunks of ore gen and mini floating forests with animal spawners every 250-500 blocks (what ever distance that will make it feel expansive).
The ore deposits would be rather large, sizeable enough to warrant quarrieing. I'd say the smallest will have dimensions of 5x5x5 the chunks may or may not be just pure ore, maybe a mix of richness.
Not sure what mods could do a sky dungeon well though, was thinking maybe RogueLike Dungeons could do it but they generate rather unpredictably and might look like a hot mess.
I would make sure open block gliders and that spring board mod where added for some neat early mid game aerial travel. Perhaps controlling the use of jetpacks (removeing them or making their energy cost prohibitive for long distance) and requireing the use of Archemedies Airships for propper long distance air travel. Of course that mod's been known to be a buggy mess so it might be better to just allow jetpacks. But if that's no longer true bring on the air ships.
But a Skyblock that was more then 'sift to success'. I'd consider doing myself but it feels like quite a time investment. Agrarian skies 2 tried to add exploration but it kinda fell flat.
