Ultra-compressed cobble, either a single octuple-compressed, or a mix of I think triple and quadruple-compressed and, in the case of the latter, a diamond block. The former needs to be smelted in order to make a bedrockium block. Even with the ultra-fast cobble generation you can get with XU, it takes a LONG time to get bedrockium.
The former recipe is very acceptable; the latter feels wrong, partly because of the diamond ingredient and partly because it is insufficiently compressed. Is the recipe in ExU configurable?
Is treu but requires minetweaker and some people (like me) prefer only to use if it is absolutely necessary and this would save some time to packsmakers to implement this into a skyblock map
I don't think so, but would putting 8x compressed cobble into a blast furnace for the same effect be acceptable? If so, you could do that (maybe making it configurable for people that might not like the idea) with the bonus of it providing a nice little bit of compatibility with XU.
You mean to make vanilla bedrock? I am fine with that, but it does not solve @Lethosos's original issue.
The grinder idea would do exactly that as well.
Would that be so you grind it away a bit at a time? i.e. it starts at metadata 0 with a full block and gets... "thinner" as you grind it?
The bedrock slice already does that. I am just suggesting making the slice itself obtainable and placeable, and since its metadata zero is a full block, it would be visually indistinguishable from bedrock.
