I've tried playing the pack in skyblock mode. In the mode I reached stone and next step is getting copper.
I've found the way to it, but can't reach it due to this problem :

• Using tinkers' Hammer on crushed diorite/andesite/granite doesn't give related sand as suggested in the JEI tab. In place of it, it drops back the crushed stone used.
  Didn't try for vanilla stone up to now. Might take a look when needed

Okey, i'll try this.
But to to that I need to find a way to get water other than waiting the rain, that is an unproductive way.
Because I don't see any other way to get the Clay needed to do the Seared components of a Smeltery.

find a way to get water

Just squeeze it from Cactus or Sugar cane

Perfect, thanks

We just create a branch on Minecraft Pack Development server for Skyblock mode: https://discord.com/channels/362322551684464641/895728152188420107

You can use this channel to ask how to craft stuff.

If current issue is resolved, please close it.

I would investigate this as soon as i can!

Skyblock currently is not fully supported, but everything until midgame should be reachable.

I just checked this recipes in game and everything working.
Pipeline is:

1. + ->
2. + ->
3. + ->

Try to pour with Blood to get red sand. Hammering it wont give red sand.
