[MC-105292] falling_block Lighting Inconsistency with Smooth Lighting on

Inconsistent lighting on falling_block entities vs blocks. Lighting glitch specific to falling blocks.

Falling Block command I used

summon falling_block ~ ~3.5 ~ {BlockState:{Name:"minecraft:quartz_block"},NoGravity:true,Tags:["FallingSandX"],Time:-2147483648}

Seems to darken falling_block left of solid blocks. Not certain positive/negative coordinates affect this.

See screenshots. Shaded blocks are the entities.

@unknown, could you check if this is still an issue in the latest 1.13 development snapshot?

Meri Diana 2018-05-24T19:34:40Z

I quickly tested with

/summon falling_block ~ ~3.5 ~ {NoGravity:1b,Time:-2147483648,DropItem:0b,BlockState:{Name:"minecraft:quartz_block"}}

and I also tried different directions and also tested to encase them, I don't see it occurring, but I'll keep it in my test world, in case anything would change again.

Thank you. I'll resolve this as fixed for now.

Yes. Still very much an issue. I had forgotten about this report. Added pics for current snapshot. It happens when blocks are placed beside the falling_block entities

Meri Diana 2018-05-24T20:33:02Z

Strange, why do I not see it on mine?

Because it happens when you place the stone in front of the falling quartz blocks, not on the same axis. Move the stone closer one block and the false shadow should appear.

Notice in the new pics I posted, the quartz blocks with command blocks below are falling_blocks the ones beside are regular blocks. See the contrast?

Meri Diana 2018-05-24T20:44:48Z

Yes I can see it on your pics. I tested different setups, but I still can't see it; e.g. in this pic, Quartz and Lapis Blocks are all falling sand, blocks behind them are stone/clay. - Maybe I'm just too exhausted, been a rough day 🙂 Sorry for reporting false then, but I'll find out what I did wrong in my setup eventually 😛

I'll post a test world, see if you can notice the difference

Meri Diana 2018-05-24T20:47:43Z

NBT file (structure blocks) would also be possible, if you like.

Thanks, I'll check and quickly get back here then 🙂

qmagnet 2018-05-24T20:50:04Z

I posted the world "Falling Block Lighting" to show the issue

That's odd. Now I'm very confused.

Meri Diana 2018-05-24T21:26:52Z

Tell me about it! On the other hand I feel better, I already thought my brain was completely gone for today.

I just asked Panda(4994) to download and check it. Maybe it's something in your or my settings, I need to check, as I tested a pack I had particles disabled for before, maybe I got some other settings changes, hold on.

Meri Diana 2018-05-24T21:29:53Z

Panda found it, it's the Smooth Lighting setting!

I had mine turned off, the shadows appear if Smooth Lighting is at least on "Minimal" 🙂

Well, at least it wasn't me being derpy or dumb, so that's a relied, and now we know 😉

Next time I'll test it, I'll remember.

Sorry for the confusion!

Panda4994 2018-05-24T21:37:09Z

It would probably be a good idea to add to the description that it only happens with smooth lighting enabled, so the devs know more exactly where to look 🙂

qmagnet 2018-05-24T21:49:44Z

Meri, do you have smooth lighting on or off?

EDIT: Ah Panda, didn't see your comment. I think that is the issue.

Meri Diana 2018-05-24T21:54:33Z

These were my settings.

And yeah, it'd help the Devs to pinpoint the issue better, inconsistencies due to some settings really shouldn't happen 🙂

Thanks Panda for helping 🙂

Meri Diana 2018-06-15T17:49:06Z

Confirmed for 1.13 pre-2.

Meri Diana 2018-11-07T09:14:32Z

Still present in 18w44a (again, only if Smooth Lighting is enabled).

Meri Diana 2018-11-08T19:35:08Z

Also confirmed for 18w45a.

Meri Diana 2018-11-25T10:36:05Z

Confirmed for 18w47b.

Meri Diana 2018-12-09T10:27:33Z

Confirmed for 18w49a (with Smooth Lighting on, which is still not mentioned in the bug description).

Meri Diana 2019-02-07T19:21:57Z

Confirmed for 19w06a.

Meri Diana 2019-02-15T17:59:31Z

Confirmed for 19w07a.

Meri Diana 2019-03-31T14:03:53Z

Confirmed for 19w13b.

Meri Diana 2019-05-22T15:10:05Z

Confirmed for 1.14.2 pre-3.

Meri Diana 2019-10-10T17:51:45Z

Can't reproduce it in current 19w41a, possibly due to the big changes regarding rendering.

As there are many bugs currently, related to rendering, I will continue to observe falling block's lighting, as they are part of one of my bugtestworlds anyway, in future MC snapshot as well as release versions.

I've tested all lighting settings, off, minimum and maximum, and on the two latter there is no darkened shading of any sorts anymore. With smooth lighting off, if you e.g. place a block above another block, it will create a shadow, however, this is not solely true for falling blocks, but also for regular, solid blocks.

wobst.michael 2020-04-12T08:41:37Z

Any news on this? Can this still be reproduced in the latest 1.16 development snapshot?

qmagnet 2020-04-12T11:42:50Z

It appears to be fixed in 20w15a
