Lava uses the water texture on multiplayer

Hi there,

A moment ago when the latest Snapshot of Minecraft came out, I immediately started up my Minecraft server. But then I noticed something like lava used the texture of water. I was taking a look in the same map but then in Singleplayer and then it had the normal texture.

Could this be a bug in the latest snapshot? (18w19a)

The title should be changed to "Lava uses the Water Texture"
Description:

The bug

Lava is not looking at all like Lava: its the water texture. It still has its behavior: Burns you. Can confuse players in the Overworld due to texture share.

Likely a bug with your graphics card, i still have lava.

@Cobalt MM.exe Thanks for the tip of the title! 😃

But did you try the bug in Singleplayer or did you joined a server? Because i did not have it in Singleplayer but in Multiplayer though

Ditto on multiplayer - zooming through the underdark in spectator mode is amusing.

They better fix this bug because it is game breaking for servers.

This bug is not fixed. Affects 18w21a as shown in attached screenshots.

Reopened because multiple users reported that the problem persists, but I'm not able to reproduce this in 18w21b.

To all who are experiencing this issue, can you check whether the vanilla datapack is enabled? There's another bug (MC-129838) that's causing lava to show as water when the vanilla datapack is disabled.

Alright, I finally got around to testing in the latest snapshot. As of 1.13 pre-release 1 The problem persists only as long as the vanilla datapack isn't loaded. Loading it and then relogging fixes the issue.

That matches the symptoms of MC-129838

The previous fix is valid.

 

The issue you are reporting now, which is specific to not loading vanilla datapack, is working as intended. If you do not provide a definition of what lava is, the client will not know and that is undefined behaviour. If you intend to replace vanilla datapack you must make your own definitions of things instead.

This should not be the case, lava should maintain it's lava texture regardless of the tag existing. Behavior should be removed (as well as it's ability to damage/hurt players and it's particles - the jumping particles) but the texture should remain intact. Otherwise, why is water still the water texture when the Vanilla data pack is removed? I understand "lava" doesn't exist - but neither does water if Vanilla is disabled - so why are the textures still water? Unless data packs incorporate resource packs, this just seems inconsistent with server's not meant to control client's resources. Either disabling the Vanilla pack should result in an error texture or lava should keep its own textures with just a loss of behavior. (Same for water). It's especially inconsistent considering the fact that the item for lava bucket maintains the lava texture when the fluid itself does not.
