To enable this build you need to select Blockscape->Properties->Betas->unstable in you Steam client.
This build gives you a working fluids tool. You can now edit water and fire. So go ahead and make your own waterfalls.
There are two versions of water in Blockscape: Inifinte water and finite water. In "just build" mode you can edit both. In survival mode you can "mine" infinite water but you can only edit finite water.
If you accidentally put something on fire you can now delete fire with the fluid tool. Works in survival mode too.
I plan to add many more fluids in the future.
Castles now works ok in the realistic world.
The realistic world now has its own set of shaders that are more realistic than the Blockscape world.
Here is the complete list but it probably makes no sense to anyone but me:
[x] Removed old fluid tool
[x] Convert block type 32 to fluids on add
[x] Fix water simulation chunk update
[x] Fluid tool should hit fluid blocks
[x] You can now delete fire with the fluid tool
[x] Convert fluids into block type 32 on delete
[x] Fix vertical water flow simulation (infinite water)
[x] Make sure the top most block is half full when _adding_ waters
[x] Fix water simulation lod border crash
[x] Fix vertical water flow simulation (finite water)
[x] Fire should not spread to water!
[x] Handle inventory when "mining" fluids
[x] Mining infinite water should give you finite water
[x] Fluids tool should be available from start in survival mode
[x] Should not be able to delete infinite water in survival mode
[x] Infinite water should absorb finite water
[x] Finite water should not overwrite infinte water levels on add
[x] Fix mesh errors near lod borders in realistic world
[x] Split some shader paths into a realistic and a blocky version.
[x] Post effects like ssao are now more realistic in the realistic world.
[x] Realistic world castles are working correctly again.
[x] Saplings should not be available in realistic world (we use seeds for trees here)
[x] Make sure the top most block is half full when _deleting_ waters
[x] Show induvidual water drops that are not part of the continuos surface
[x] Water drops should snap to surface below
[x] Fix horizontal water flow simulation
[x] Water drops should only be generated for blocks inside the current chunk!
[x] Fix fluid surface discontinues near chunk borders
[x] Water drop size should be proportional to the level in that cell
[x] If no surface below then water drops should snap to any surface on its side
[x] Remove water drops logic. It didn't work so well.
[x] Water surface level errors between lods in realistic world
[x] Change fluid surface extraction so that it only looks at fluid corners
[x] Handle vertical fluid simulation at voxel corners instead (did not work!)
[x] Holes in fluid mesh near vertical walls?
[x] Cursor should be visible through water
[x] Fluid tool default mode should only hit water blocks that are full (all corners set) (did no work!)
[x] Undo fluid simulation at voxel corners
[x] Fix water mesh overlap render errors (cut faces at chunk borders)
