16:25 Krock Any comments on #4330 ? A simple bugfix but I'm not sure if this belongs to verbosestream or not

17:27 paramat hmmmm nore sfan5 sofar Zeno` a simple PR with huge performance benefit #4336
17:27 ShadowBot https://github.com/minetest/minetest/issues/4336 -- Shaders: Disable by default by paramat
17:33 Krock it doesn't solve the source of this problem
17:34 paramat correct, the proper fix is difficult, see discussion
17:36 paramat as explained, this is hopefully temporary
17:39 VanessaE RBA and I have gone round and round over shaders in the past.
17:40 VanessaE fwiw, I usually won those arguments ;)
17:40 VanessaE he had plans to further separate-out the different "pieces" so that e.g. tangent space could be called for only when needed.  Not sure how far he actually got with that.
17:46 SloanOnLinux joined #minetest-dev
17:52 jin_xi this PR is palliative care
17:54 paramat yes, as explained *=S good grief
17:55 davisonio joined #minetest-dev
17:59 jin_xi well ffs change line 372 as well then. "...may increase performance on some..."
18:00 paramat the issue is the default, new players joining at a built-up spawn and getting 14 instead of 27 FPS
18:01 paramat the visual difference being barely noticeable
18:02 paramat "Eventually, once we only enable tangent space when it's needed, we can re-enable the basic nodes shader."
18:03 jin_xi i only use shaders for smooth day-night but thats a big one. still i don't thinks shaders can actually improve performance for anyone now that tangents are done regardless
18:04 paramat tangents are done only when shaders are enabled
18:04 paramat so essentially we've almost halved the performance of MT for no reason at all
18:05 paramat this is the simple temporary fix
18:05 paramat and players can always choose to turn shaders on
18:06 jin_xi it's ok im not even arguing that. just saying that the line in the conf example should be changed
18:06 jin_xi so it does not suggest shaders improve performance
18:06 paramat ok
18:07 paramat heh i can't believe it says that
18:07 paramat that was RBAs doing i'm sure
18:07 jin_xi it might have been the case before that tangent stuff was added
18:08 jin_xi i think its lighter to do day night in the shader than to update all the meshes
18:08 damiel_ joined #minetest-dev
18:08 jin_xi which is why it's really a double blow, that whole issue
18:08 paramat ok, that line is misleading, will change it

18:57 Krock Now I understand why map_generation_limit wasn't made world-specific
19:06 paramat ?
19:06 paramat some think it needs to be
19:10 Krock #4338/
19:10 ShadowBot https://github.com/minetest/minetest/issues/4338 -- Make map_generation_limit per-world specific by SmallJoker
19:11 Krock It wasn't easy to keep an eye on about 15 different files :<
19:11 paramat i see
19:15 earthrocker joined #minetest-dev
19:16 Krock there are a lot different connections between mapgen-environment-servermap and so on. Is there any document that would describe how they access eachother?
19:17 Krock it looks like an infinite spidernet - on 3 dimensions
19:31 Krock aagh. the unittest fails because the cardcoded hash does not equal the new settings :<
19:35 Fixer https://imgur.com/uYkS3Ko JUMPING LIKE A BOSS (yes, it is bug nobody fixes)
19:47 Fixer https://github.com/minetest/minetest/issues/329
19:58 Miner_48er joined #minetest-dev
20:02 hmmmm map_generation_limit is implemented in a crummy manner to begin with
20:03 hmmmm why is it so far overreaching?
20:03 hmmmm the map_generation_limit should limit map generation.  not everything else in the entire universe.
20:04 hmmmm instead what the guy did who implemented it first added a parameter to a fundamental function that just about everything uses to make sure objects or positions are not out-of-bounds and will cause bugs or errors
20:04 hmmmm when in reality it should simply... limit the map generation
20:04 hmmmm i could (and should) fix this by rolling back the majority of the map_generation_limit scope creep
20:05 paramat agreed
20:05 paramat so all outer mapchunks would be solid ignore
20:06 Krock currently they are solid ignore
20:08 paramat ok yes
20:09 Krock also would this now be a setting that shouldn't be changed, like the water level or chunksize
20:09 Krock so I think limiting the objects and players is fine
20:10 hmmmm i really hate to say this but
20:10 hmmmm your PR is a mess.
20:11 Krock \o/
20:11 hmmmm i would prefer if it's not implemented like that at all
20:11 Krock But then I'd like to see another way to solve this because I think this must be a per-world setting
20:12 Krock however, if it gets too complicated we could just drop that idea
20:12 hmmmm it's already kinda complicated...
20:12 Amaz joined #minetest-dev
20:12 Krock indeed
20:13 hmmmm also i saw your rawstream << (int)sha1_result[i] << " ";
20:13 hmmmm i can't accept that
20:13 hmmmm that's circumventing the purpose of the unit test
20:13 Krock yeah.. no idea how kwolekr generated that char array
20:13 hmmmm it's not a hurdle to jump over, it's a check to make sure the output is what you acutally want it to be.
20:14 Krock but I have no clue where it puts the space or even how the real output will look like
20:14 hmmmm maybe he made sure the file being output was 100% correct and then ran sha1sum on it
20:16 paramat heh

20:37 paramat saw that
20:37 paramat updateLighting has serious problems but it's nightmare code
20:39 paramat updated 4336
20:43 KaadmY celeron55: do you have a moddb account named "exmex"?
20:43 Tmanyo joined #minetest-dev
20:43 KaadmY because at http://www.moddb.com/games/minetest, the guy that put it up(exmex) is implying he made it
20:44 celeron55 he clearly is not implying that
20:45 celeron55 it's ridiculously outdated though
20:45 KaadmY yea
20:46 Krock paramat, updateLighting as a nightmare - I'd say that just fits perfectly :P
20:47 KaadmY the description seems to also be copied straight from a readme or such
20:48 Krock he copied it from the old minetest.net site and extended it a bit
20:48 KaadmY ah
20:49 Krock and it's completely outdated so why care about it?
20:49 KaadmY because it's outdated? ;?
20:49 KaadmY ;)
20:54 celeron55 well you have my permission to get it updated
20:54 celeron55 if that matters
