Honey has a strange behavior with blocks that have the same density #119

Open DianaTavares opened 2 months ago

A teacher during the Buoyancy feedback identified the next:

dropped object of same density as honey into honey and the top of the totally submerged object remained flush with fluid surface (no matter the drop height). dropped object (of same density) into a custom fluid having the same density as honey and the totally submerged object could be observed suspended some distance below the surface of the fluid (final distance below surface affected by drop height)

object with the same density of honey dropped in honey at any height: image

same object in a fluid with the same density of honey, just by changing honey to custom: Buoyancy

same object dropped from a height in a custom fluid with the same density as honey:

I wonder if this is just a drawing error? Could changing the material cause this to go away? @AgustinVallejo also mentioned that this may just be working as expected. I feel like the main bug is in seeing "100% submerged" when there is still a layer of block showing without liquid on top. We will get to this bug after we are feature complete though.
