S3ctor	One thing I would personally like to get into soon is doing groundcover records natively.	09:53:31

anyoldname3	The MGE XE groundcover was only accepted on the grounds that it was purely for legacy mod support (and a little bit because some people misunderstood and thought you might have a chicken before an egg even though you can't change species after being born, so the first chicken came from a chicken egg laid by an asain jungle fowl or something between one of those and a chicken, so thought that there would be usable data in exising MGE XE grass mods that we could feed into a modern groundcover system).	01:46:06
anyoldname3	I wouldn't necessarily object to supporting a common better-way-of-representing-MGE-XE-groundcover-mods system with MGE XE, but if we copy the system from Skyrim (which we'll have to for Skyrim support) or Horizon: Zero Dawn etc. (which should allow lots and lots of pretty groundcover and be relatively cheap to render), then that won't be something MGE XE can do, too.	01:48:52
zackhasacat	I want to get this mod working in OpenMW(lua): https://www.nexusmods.com/morrowind/mods/46680 Got a working way to do it in c++, but it is the hackiest code ever: objectT["nodeTest"] = [lua = context.mLua](const GObject& object) { SceneUtil::PositionAttitudeTransform* pat = object.ptr().getRefData().getBaseNode(); if (pat) { osg::Node* node = dynamic_cast<osg::Node>(pat); if (node) { // Function to recursively search for the node named "BookSwitch" std::function<osg::Switch(osg::Node)> findSwitchNode = [&](osg::Node currentNode) -> osg::Switch* { if (!currentNode) return nullptr; // Check if the current node is the "BookSwitch" switch node if (currentNode->getName() == "BookSwitch") { return dynamic_cast<osg::Switch>(currentNode); } osg::Group group = currentNode->asGroup(); if (group) { for (unsigned int i = 0; i < group->getNumChildren(); ++i) { osg::Switch* foundNode = findSwitchNode(group->getChild(i)); if (foundNode) return foundNode; } } return nullptr; }; osg::Switch* switchNode = findSwitchNode(node); if (switchNode) { // Toggle switch index or perform other operations if (switchNode->getValue(0)) { switchNode->setSingleChildOn(1); } else { switchNode->setSingleChildOn(0); } } } } }; I'm guessing this pretty much needs to wait for wazabear 's scenegraph API?	04:15:40

zackhasacat	Actual function could be something like "findSwitchNode("BookSwitch")" or nodes["bookSwitch"] = 0	04:17:07
wazabear	ya you could do this with my MR	04:18:37
wazabear	sorry I've not had time to finish it up	04:19:05
zackhasacat	Take your time, as long as you can get it merged by the end of 2023 I'll be happy	04:19:25
wazabear	Oh for sure	04:19:32
wazabear	The original goal was 0.49	04:19:41
zackhasacat	I still believe it can be there for it	04:19:56
zackhasacat	Maybe break it up and add smaller bits of it?	04:20:04
wazabear	wait	04:20:05
wazabear	it's 2024	04:20:11
zackhasacat	Yes	04:20:26
wazabear	I don't know I'm afraid if I do it the functionality will remain useless. I'd rather make it somewhat powerful otherwise I doubt I extend	04:20:56
zackhasacat	There are only 3 unresolved threads	04:20:59
zackhasacat	I can write the docs for you	04:21:10
wazabear	let me catch up on where I left off, lol	04:22:58
wazabear	okkk, so I rebased on master. fixed some bugs with inserting/removing...	04:23:37
zackhasacat	uhhhhhh	04:24:21
zackhasacat	I thought this was the #development channel	04:24:28
zackhasacat	oops	04:24:28
wazabear	what's left is to add the bindings for mesh internals. of course there's the docs, but that honestly is no big deal, will take 20 minutes even with examples	04:25:10
wazabear	mesh internals being able to access things like switch nodes --- maybe I just add switch nodes only for now	04:25:39
wazabear	that could be good compromise	04:25:43
zackhasacat	It would be nice	04:31:55
zackhasacat	If not, I'll have to make new items for all these books, and that'd be a pain	04:32:08
