 Description   

The bug

When 7 snow layers are stacked and if a snow block is placed behind, the layer will get darker, but when you replace the snow block with a stack of 8 layers, it's fine.

22w12a makes the extra darkness also be casted from 8 layers onto 7 layers, so that inconsistency is gone. However, the fact that 8 snow layers cast a shadow onto 7 layers is still present, which is itself an inconsistency since 7 doesn't darken 6 and so on.

I think this ticket should be resolved as Fixed, as the second issue is already covered by MC-64678 (8 casting onto 7), as well as MC-139621 (1-7 not casting onto the block below it).

Can confirm in 20w51a.

pulpetti only say what versions it currently affects not past versions all your doing is blowing up emails

Comment by pulpetti [ 06/Jul/20 ]

Affects 1.16.1

Comment by Connor Steppie [ 12/Dec/18 ]

This could actually be considered a duplicate of MC-139621, as I'm pretty sure snow layers are meant to have shadows casted on them by all blocks, including higher snow layers.

I can only reproduce this the other way round:

  • 7 layers of snow in front of 8 layers of snow = OK
  • 7 layers of snow in front of a full snow block = dark
    (See the fence post connecting to the full snow block)
Comment by Lexa Mink-Flacco [ 15/Mar/13 ]

I've reproduced this error in a newly-updated version: force 1.5 update, then manual .jar replacement with the snapshot. I used a newly created world. Mac OSx 10.6.8, running the MultiMC app.
Confirming: I placed a block of snow, then built up the snow on one side of it to one level below, and the glitch happened. Placed the nearly-full block then the block, and got the glitch. Placed the nearly-full block then the block made from 8 built-up layers, and no glitch. Hope this helps!
