Steps to Reproduce:
1. Turn on RTX.
2. Place TNT above water 1 or more blocks of water.
3. Light the tnt and have it all into the water
Observed Results:
The tnt turns invisible
Expected Results:
The tnt should be visible through the water
If I dunk my head into the water, then the tnt becomes visible again, so it's only when the player is in air, but the tnt is in water. This also occurs if the water is flowing water.
Affects myself as well in beta 1.17.40.21, I've attached a screenshot. Here is the PBR resource pack I was using: https://www.mediafire.com/file/ngisqn3mkjn4c44/Defined_PBR_v1.1.5.mcpack/file
