00:46 paramat testing #4745 seems to show not much reduction in mesh updates, so i'm feeling all 'meh' about this now
00:46 ShadowBot https://github.com/minetest/minetest/issues/4745 -- Digging crack animation: Make crack animation optional by paramat
00:55 paramat i'll let it sit for a while as low priority
00:56 garywhite I do think it'd be a good idea, reduce client resources a bit, but I don't think it's needed in 0.4.15
01:06 paramat surprisingly the reduction in mesh updates is almost insignificant
01:08 OldCoder <paramat> no need, we already always notify people
01:08 OldCoder Those announcements include API changes, paramat?
01:08 OldCoder If so, issue is addressed
01:09 paramat yes
01:10 est31 I think performance isn't a reason to be in favour of the PR
01:11 est31 I don't like it much
01:11 est31 but it doesn't change the default, so I'm not against it

11:44 celeron55 let's just add this new word to the english language: seguttion
11:44 celeron55 it's like a suggestion, but definitely bad

21:23 paramat sofar https://github.com/minetest/minetest_g​ame/issues/1397#issuecomment-261739872 i'll get to work on this suggestion if no objections
21:26 sofar weird though
21:26 sofar wasn't even auto converted, I just changed the mode in gimp
21:27 sofar indeed when I flatten aspen leaves the alpha pixels turn to a color, but it's black?
21:27 sofar sorry, green
21:32 sofar paramat: can you try this version?
21:32 sofar http://i.imgur.com/freXpXz.png
21:34 sofar I wonder if optipng can just fix it automatically
21:34 Brikooba joined #minetest-dev
21:37 paramat ok will try it
21:37 Brikooba paramat: I tried to clone your repository for swimsounds and I think something is wrong.
21:37 Brikooba --with my clone.
21:37 paramat it needs rebase
21:38 paramat so testing my PR may be problematic
21:40 paramat sofar yes that aspen texture has no bug
21:40 sofar so that's saved without the 'color for transparent pixels' option in gimp
21:41 sofar but, try just running optipng on them
21:41 sofar I think that does the same thing
21:41 sofar and may be easier
21:41 sofar tbh I can't see from the screenshots what the problem entirely is, rails?
21:42 paramat i can't see a problem with rails
21:42 WaterReflowBug i will explain
21:42 WaterReflowBug look at grass - it turns to red at far distance
21:42 Brikooba 1 problem is with my clone and i figured it out.
21:43 paramat red and blue
21:43 WaterReflowBug rails - turn to green or dirty - before index change it was turning to black
21:43 sofar ah
21:43 sofar heh, so it was wrong before as well
21:43 WaterReflowBug no
21:43 sofar WaterReflowBug: can you run optipng on them?
21:44 WaterReflowBug no
21:44 sofar see if that helps?
21:44 WaterReflowBug or
21:44 WaterReflowBug maybe yes
21:44 WaterReflowBug sofar: rails looked good before indexed change, now they look wrong
21:45 WaterReflowBug found optipng bins
21:45 paramat leaves have to be done manually, programs tend to set the opaque colour wrong
21:45 sofar they just happened to mipmap to the right color by chance
21:45 paramat yeah possibly
21:46 paramat i started using mimap a few weeks ago, and have noticed alpha textures looking odd in the distance
21:46 paramat but assumed that was expected
21:46 paramat they may have been bugging out but to a not so problematic colour
21:47 paramat so perhaps indeed all alpha textures must be RGBA
21:48 paramat anyway, lets not base our textures on these buggy ones, revert alpha textures first
21:48 Brikooba I got it now.  Sounds nice. It is a little low compared to footstep sound.
21:48 WaterReflowBug grass 3 4 5 and side optimised, will see
21:48 paramat yeah might need a little more gain
21:48 Brikooba It's good.  A touch louder would be better, i think.
21:48 WaterReflowBug 1 and 2 already optimised
21:50 WaterReflowBug sofar: won't help, still red
21:50 sofar ok, so optipng doesn't remove the alpha pixel color
21:50 sofar now we just need a list of files affected
21:50 WaterReflowBug https://i.imgur.com/NodChPv.png
21:51 WaterReflowBug i have no idea what is affected, could be everything
21:51 sofar my eyesight isn't bad, but can you make larger screenshots? lol
21:51 sofar I know how to fix it now
21:51 WaterReflowBug sofar: ctrl+scroll
21:51 sofar ctrl-scroll makes it fuzz :P
21:51 WaterReflowBug you will recognise
21:51 WaterReflowBug looks like alpha channel is red
21:51 sofar it's not actually, I think
21:52 WaterReflowBug or entirely
21:52 sofar it's light green actually
21:52 Brikooba Do you want to remove alpha channel on some images?  I've done that from command line.
21:53 Brikooba Level -o4 is good for optipng.  If you want to burn much CPU, sure go higher.
21:53 WaterReflowBug i did optifine -v *.png
21:54 Brikooba If you have a cloud computer and don't pay for CPU, you can go brute force all combinations.
21:54 Brikooba optifine, i don't know yet.
21:55 paramat so, it's 'save colour from transparent pixels' which is the issue?
21:55 sofar yup
21:55 Brikooba What does optifine do?  I see it is related to minecraft.
21:55 paramat the gaps in leaves need to change to the correct colour when 'opaque', be careful with that
21:55 sofar Brikooba: optipng
21:56 sofar Brikooba: optifine is a minecraft hack, unrelated
21:56 WaterReflowBug https://i.imgur.com/N2TYh3k.png when I zoom in, notice reddish part in the middle of grasses (put your glasses on)
21:56 sofar WaterReflowBug: optipng, not optifine
21:56 WaterReflowBug optipng
21:57 sofar paramat: so grasses, aspen leaves, rail?
21:57 paramat yes grass close up shows red if one of the planes is at a small angle to view
21:57 paramat sofar all alpha textures will need fixing
21:57 WaterReflowBug btw
21:58 WaterReflowBug i've noticed default rail takes longer to dig in creative
21:58 Brikooba WaterReflowBug: default level is -o2.  difference is o2 does filters 0,5 ; o4 tries filters 0-5.
21:58 WaterReflowBug i thought that was fixed
21:58 paramat leaves though may have to be RGBA due to the gaps needing a certain colour when 'opaque' is used
22:05 paramat actually, no, because your aspen leaves texture i tested was ok
22:06 paramat so to clarify. we can use indexed for all textures, but textures using alpha must not 'save colours from transparent pixels'
22:06 sofar opaque changes alpha pixels to black I think
22:06 paramat black is fine for the gaps in leaves in opaque mode
22:07 paramat i think most leaves do that already, apart from aspen
22:07 paramat thisis going to be a huge job
22:08 WaterReflowBug why not just reverting this textures back
22:08 WaterReflowBug those
22:08 paramat i suspect this bug has been present for a while, but was not noticed because the 'bug colour' was not red
22:10 paramat sofar shall we revert the alpha textures first, to partly fix this quickly?
22:10 paramat the non-alpha textures are ok afaik
22:18 paramat sofar it seems to me that all MT textures that use alpha will need to be resaved without 'save colour from transparent pixels', because it is impossible to tell if they were saved correclty originally, and because the bug may be present but visually unnoticeable
22:21 paramat for now i'll fix tool break gan
22:21 paramat (gain)
22:26 paramat ha i've just noticed the bug is present for dry grass, we just didn't notice it before
22:26 paramat dry grass has been buggy for a year
22:26 paramat with mipmap on
22:30 paramat hm resaving as i mentioned didn't fix them though
22:34 paramat resaving as RGBA does fix them
22:34 jin_xi joined #minetest-dev
22:37 paramat sofar ^ RGBA is necessary after all, it fixes the bug with or without 'save colours from transparent pixels'
22:37 paramat i just fixed dry grass this way
22:39 paramat so all indexed alpha textures must be converted to RGBA
22:40 paramat this can be partly done by reverting the alpha textures just changed (copy them into a PR from an older version)
22:41 paramat then we can change the others later
22:47 sofar paramat: I've been looking at auto converting them, but, kids...
22:47 paramat ugh auto ..
22:48 sofar reverting is fine, I'm ok with that
22:48 sofar I can re-fix the invalid srgba profile anyway on a case-by-case bassis
22:48 paramat i shall revert the alpha ones then
22:49 paramat within an hour or so
22:49 WaterReflowBug sofar: make kids do it
22:49 WaterReflowBug done
22:50 paramat lol
22:51 sofar I wish
22:52 sofar my 2yr old can barely properly use a tablet, so, not gonna happen any time soon
22:52 sofar the other 2 aren't into hacking stuff yet
