but code flow and logic is the same

plush yew Sep 18, 2016, 4:20 AM

#

well for some things it is convinient to be on the C++ version if I am doing C++ such as on SuggestProjectileVelocity

#

on the blueprint version https://docs.unrealengine.com/latest/INT/BlueprintAPI/Game/Components/ProjectileMovement/SuggestProjectileVelocity/index.html

SuggestProjectileVelocity

#

It says Trace Option is an enum but doesn't say what the enum can be

#

on the C++ version
https://docs.unrealengine.com/latest/INT/API/Runtime/Engine/Kismet/UGameplayStatics/SuggestProjectileVelocity/index.html

Based on analytic solution to ballistic angle of launch http://en.wikipedia.org/wiki/Trajectory_of_a_projectile#Angle_required_to_hit_coordinate_.28x.2Cy.29.

#

I can click through and see what the choices are

#

well, its not really a problem with the docs, its just me trying to shortcut my way to the C++ versions that don't show up high on the search

#

so its really a personal problem

polar hawk Sep 18, 2016, 4:38 AM

#

Ah, the API docs

#

well, the issue with that is that 95% of those docs are auto generated and not hand made

#

And no one really uses it because of that

#

So not enough people complain about things like that

#

It really doesn't make sense that the blueprint api docs have links that do nothing

#

I'm pretty sure this is publicly accessible now

@hollow dune What were the assets you moved?

#

Well I guess it might have been too long pathways for the cooking to finish

hollow dune Sep 18, 2016, 4:46 AM

#

@plush yew I removed everything, still wouldn't compile, I added all the content to a fresh project, it works

#

something was wrong with that project file specifically

plush yew Sep 18, 2016, 4:46 AM

#

sometimes projects can get corrupted like that, good thing you got it solved though

cursive dirge Sep 18, 2016, 7:12 AM

#

@plush yew I'd actually like crosslinking between bp and cpp api

#

I've suggested that a long time ago too

#

Usually it is the other way around and how Allar said

#

BPs have almost always some description unless it is a enum or struct

#

Where cpp api is mostly generated and not useful for anything else but browsing the functions and class hierarchy

#

Almost every time I open cpp api page for a function it's like this "DoThis() - Does this"

#

Most descriptions are something you can figure out from function name already, so they are pretty much pointless

Hey, I have a question: Can I change the color of text in the output log?

#

Not all the text. Just specific things that I put there?

#

...and with blueprints?

distant needle Sep 18, 2016, 6:20 PM

@hybrid scroll Expand the Print node. there's a color option there

dapper granite Sep 18, 2016, 8:46 PM

#

really dumb question but for some reason my viewport resolution has gone way down, its super pixelated, I've tried a bunch of setting but it still stays pixely, is there a way to fix this?

kindred viper Sep 18, 2016, 8:47 PM

#

swcreen percentage probably

#

*screen percentage

#

try opening the console and typing r.screenpercentage 100

Isn't there docs up about it?

seems you can't just import them now. you have to reference them

@distant needle Lol. when was this added? Anyway, this doesn't work with output log, just on screen. And is per string, not per character, so not exactly what I was hoping for. But thx.

distant needle Sep 18, 2016, 11:23 PM

#

@hybrid scroll warnings are yellow, errors are red

#

ok I think I know

#

setting messages as warnings or errors colors them

#

plus you can explicitly set a color

#

but that's available through C++

nah, I have a base level, which has litterally nothing in it

I've made sure my game can ba modded, now I'm taking a look at the actual workflow for modders, and it looks bad

kindred viper Sep 19, 2016, 10:05 AM

#

have an idea how to set it up but I was kind of hoping there would be a standard way

cloud cobalt Sep 19, 2016, 10:06 AM

#

Basically the Epic-recommended way appears to be "ship the editor version of your game"

#

And then the modders can use the session frontend to launch a plugin build on top of your release

#

It produces a nice .pak file that works like a patch, which is cool for Steam etc

#

But I'm not very happy with having to distribute the game + editor + uncooked assets, basically anyone can rebuild the game as-is

#

(On top of being a pain)

kindred viper Sep 19, 2016, 10:07 AM

#

yeah im not into that idea although I did love getting UE3 games that came with an editor, like Ravenshield.

hollow dune Sep 19, 2016, 10:09 AM

Oh nice. maybe its ready when our game is also ready. We also want to ship a Editor with it. But we also want it only to be a level editor.

cloud cobalt Sep 19, 2016, 10:18 AM

#

I doubt it's coming anytime soon, modding looks very low priority for Epic

#

What they actually did this year is DLC support

#

Which is fine, mods work like DLC, but I can't shake the feeling that they don't really care about it

grand python Sep 19, 2016, 10:21 AM

#

Yep. i mean i'm fine with the current options. But its still UE4 with nearly all features when you just want to do a custom map.

#

and then getting that into the game itself. Sure that Modders will accomplish that. But i don't see newcomers that want to try out modding for the first time to get warm with that

I for myself started getting into modding and Developing trough Hammer Editor

I think before worrying about modding one needs to worry about game becoming a huge success with large number of active users. Even then most players will only mess with modifying skins and stuff like that.

I think it vastly depends on your game.

In our case, adding decent modding support took us only hours because of how the game works

So even if only 5 people try to add mods, it's not like anyone's time was wasted

Its just another headache for Devs lol but as a player its just another thing your game offers even if they never use it

I always wanted to make a hack game mode, where if the game detects a hacker there not banned there put in lobbies with only other hackers LMAO!

#

Hackers playing hackers can lead to them quitting there hacking ways lol or quit the game.

cerulean sequoia Sep 19, 2016, 12:54 PM

#

in general, mod support usually outweighs time and resources that had to be spend creating it. it increases the games lifespan, draws in potential new customers and has several other benefits, maybe it spawns another DayZ type of mod that popularizes the entire franchise. Even if you as a dev think your game is too complex for mod support (I'm looking at your Red Faction Guerilla and Battlefield 3!) people are smart, and modders can figure stuff out on their own.

@grand python How do you plan to have the modding? To extend the editor to some extent, to the players?

grand python Sep 19, 2016, 1:02 PM

#

No idea right now. Main priority is the game it self right now

#

But i guess since we mainly want it just for custom maps. Like Squad/ARK and VR Funhouse did it

plush yew Sep 19, 2016, 1:03 PM

#

Ok well if it comes to the point and you want to add modding, then extending the editor will require epics permission, as it would otherwise be illegal, so you need to do it in conjunction with Epic Games
@blissful reef If epic hasn't changed their policy that is

grand python Sep 19, 2016, 1:04 PM

#

Sure

blissful reef Sep 19, 2016, 1:04 PM

#

Policy hasn't changed

#

and you can modify the editor without our permissions

plush yew Sep 19, 2016, 1:04 PM

#

But not extend it to players for usage like in ARK

blissful reef Sep 19, 2016, 1:04 PM

#

it's the redistribution part that requires permission and to be distributed via our launcher if i recall

plush yew Sep 19, 2016, 1:04 PM

#

Yes exactly, that is what I was talking about 😃

#

Just don't want @grand python to dig their team into a legal ditch so better to infrom way ahead of time then that they do it without knowing the policy

#

😃

grand python Sep 19, 2016, 1:06 PM

#

I'm aware of that but thanks

cloud cobalt Sep 19, 2016, 1:06 PM

#

@blissful reef is there an official modding guide from Epic ? There is an Epic-authored modding guide on the wiki, but it only covers the purely technical aspects of it.

#

No mention of how the editor would actually be distributed to modders

blissful reef Sep 19, 2016, 1:07 PM

#

you'd talk to someone on the marketplace team and get slotted in the modding section like Ark

grand python Sep 19, 2016, 1:07 PM

#

Preferable would be (if the game is on steam) trough the "Tools" tab in steam. Otherwise like ARK and Squad did it via the Epic games launcher

cloud cobalt Sep 19, 2016, 1:11 PM

#

@blissful reef So basically you need Epic's permission to have mod support in your game ?

blissful reef Sep 19, 2016, 1:11 PM

#

yes / no, depending on how it's structured

#

If you need to redistribute a modified editor, yes.

#

if you just require a specific editor version, and have some plugins you provide, through some other means, but works on vanilla release, nope

cloud cobalt Sep 19, 2016, 1:13 PM

#

Okay, that makes sense.

blissful reef Sep 19, 2016, 1:13 PM

#

The license does not say 'you need our permission', i believe the actual text says, you must only redistribute modified editor / engine code to other licensees

#

the launcher happens to be a good way to do that

#

all of this information is not provided by a an epic lawyer, im not your lawyer, read the license...etc...etc...etc

plush yew Sep 19, 2016, 1:14 PM

#

Non editor mod tools = No permission,
Extending editor as mod tools = Permission

cloud cobalt Sep 19, 2016, 1:15 PM

#

@blissful reef So if you only need vanilla Unreal, you're only supposed to tell modders to get UE, then open a project you provide

blissful reef Sep 19, 2016, 1:15 PM

#

yup

cloud cobalt Sep 19, 2016, 1:15 PM

#

correct, they still need to get it via the launcher, sign up...etc

Last question, if I may abuse your patience : in this setup, you have to provide everyone with your source assets, correct ?

#

Assets won't be read-only like they were in UT3 for example ?

Still trying to understand exactly how people would mod our game 😃

grand python Sep 19, 2016, 1:28 PM

#

I don't know your game so i can't help you :P But in general. Custom maps are always a possibility

#

skins. and retextures

#

up to complete conversions

cloud cobalt Sep 19, 2016, 1:29 PM

#

The game side is done for us, to be clear. Mods could already add any content, replace materials, etc. The big unknown is the process modders will have to follow.

#

It's more a question of how to get the tools to the modder than a technical issue n the game

grand python Sep 19, 2016, 1:30 PM

#

oh. yea

cloud cobalt Sep 19, 2016, 1:30 PM

#

For example, we don't know if it's possible to generate a DLC with an arbitrary part of the contents

#

Unless you have the release artifacts from the latest build

#

We don't know if builds can be compatible with newest releases, assuming contents stay compatible

#

Basically we feel like no guidance is available on the process & release front

grand python Sep 19, 2016, 1:32 PM

#

Ah i see

#

That's stuff we also have to go trough (if we add modding). So its also relevant to us. @cerulean sequoia

plush yew Sep 19, 2016, 1:33 PM

No when releasing you will most likely be using the same version of unreal, won't be able to upgrade smoothly

you just have to provide updated modding tools then

#

Yeah, sure, but this is the sort of stuff I'd like to know

grand python Sep 19, 2016, 1:35 PM

#

sure. stuff like that happens but cou cant really do anything against it

#

Unless you restrict what can be modded.

cloud cobalt Sep 19, 2016, 1:36 PM

#

What ? i'm just trying to understand what would happen

#

I don't want to restrict anything

#

I want to know if I can provide modders with a decent path to mods

#

And what that path is

grand python Sep 19, 2016, 1:38 PM

#

Hm... I only can think of shipping the UE4 editor with your game. then modders would have to look up everything on thier own

cloud cobalt Sep 19, 2016, 1:38 PM

#

You can't do that.

grand python Sep 19, 2016, 1:39 PM

#

? i Thought you can do that if you get the permission

#

i'm confused

cloud cobalt Sep 19, 2016, 1:39 PM

#

Yeah if you release through Epic Launcher after being approved by Epic sales team

#

Like the 1 previous title that did it

cerulean sequoia Sep 19, 2016, 1:39 PM

#

you can't ship the editor with the game

cloud cobalt Sep 19, 2016, 1:40 PM

grand python Sep 19, 2016, 1:40 PM

#

Ah okay

#

So.. Then this would be the only way to do it right now ?

cerulean sequoia Sep 19, 2016, 1:40 PM

#

either you release a plugin that works with the default editor, or you talk with the marketplace team to get your mod kit in the launcher

grand python Sep 19, 2016, 1:40 PM

#

via the launcher ( mods tab )

cerulean sequoia Sep 19, 2016, 1:40 PM

#

or you give them the uproject :P

grand python Sep 19, 2016, 1:41 PM

#

Thats basically the same as the modding kit in the epic games launcher

cloud cobalt Sep 19, 2016, 1:42 PM

#

If you're shipping and Steam or other, according to @blissful reef the process is to distribute your .uproject and all sources, contents along with it. Then people get Visual, build the game & editor, do mods.

#

Q : Do modder require the release artifacts as well (stuff in /release/ folder) to be able to build a DLC ?

#

Q : Can this SDK still work if for example you add new content, unrelated to mods ? Or do modders always need the latest version ?

#

Q : Do game updates (say a minor texture tweak) break previous mods ?

grand python Sep 19, 2016, 1:44 PM

#

wait. dont you want to do mods as a .pak or something?

plush yew Sep 19, 2016, 1:44 PM

#

Ark doesn't use the Editor tab, they only have their game their but clicking the downlaod modding tools button only redirects you to instructions on how to install the modding tools, but it's great for exposure of the game

cerulean sequoia Sep 19, 2016, 1:44 PM

#

care to explain?

cloud cobalt Sep 19, 2016, 1:45 PM

#

I do want mods to be a patch-like .pak file, as explained by the wiki here : https://wiki.unrealengine.com/Modding:_Adding_mod-support_to_your_Unreal_Engine_4_project

Modding: Adding mod-support to your Unreal Engine 4 project

#

But this process requires the release artifacts from the latest published release

#

My first question is : do I have to provide this artifact or can DLC be built without it ?

#

It's really a question of what do modders need to be able to create mods

#

AFAIK the session profiles are user-specific and can't be distributed easily, for example

cerulean sequoia Sep 19, 2016, 1:48 PM

#

they are not stored in the project yes, but instead in appdata I think

cloud cobalt Sep 19, 2016, 1:49 PM

#

Yes

#

I mean, the overall process sucks, for the developer and the modder

cerulean sequoia Sep 19, 2016, 1:51 PM

#

yeah it sure isn't properly streamlined and requires unnecessary steps that shouldn't be there, session profiles and all that

cloud cobalt Sep 19, 2016, 1:52 PM

#

Another issue is that I can't redistribute some of my contents (marketplace assets)

#

So I would have to exclude them from the SDK

#

But then the DLC build would detect the discrepancy between the asset registry and contents

cerulean sequoia Sep 19, 2016, 1:53 PM

#

I would really love an option for cooking mods via the content browser, maybe you have to create a new folder for your mod stuff and you put all your custom content in there, then rightclick the base folder and click on something like "cook mod" and it does all the rest for you

#

yeah we would need a proper asset manifest that would work without marketplace assets

cloud cobalt Sep 19, 2016, 1:54 PM

#

Going to write a thorough thread on forums to ask all of this

cerulean sequoia Sep 19, 2016, 1:54 PM

#

you should be able to mark a folder as "do not include in manifest" or something

#

I would love if you pm me the link to it once you wrote it :)

grand python Sep 19, 2016, 1:55 PM

#

Send the link to the thread when you're done. Wanna see the outcome

blissful reef Sep 19, 2016, 2:30 PM

Hello,

After years of work, my game is nearing completion, and we've started taking a closer look at modding. Our title supports it on the technical side - we can detect and use mod content, assets can be replaced, etc. The game-specific part is all but done. The releasing and process issues appear to be much more complicated that anticipated, though. After much discussion on UnrealSlackers and this forum, some questions are still up in the air. Let's get to it :)

My game has a

@blissful reef I already did 😃

I am almost certain no one will mod your indie game (at least in the quantifiable numbers) unless your game gets as big as a handful of indie hits out there (Minecraft?!)

cloud cobalt Sep 19, 2016, 2:36 PM

#

It's not like we care how many people do it. People have been asking for it, we like it, it's trivially done in the game itself.

cerulean sequoia Sep 19, 2016, 2:42 PM

#

"no one" is a concept that doesn't exist in modding, there is always at least one who will try. There are freaking mods for obscure games that don't even have a modkit.

#

also comparing anything to minecraft is dumb, minecraft sold better than a lot of AAA games

vale silo Sep 19, 2016, 2:46 PM

#

I am simply pointing obvious out.. Indies have limited resources to make and maintain a game (and by indies I don't mean ex-AAA with large savings, connections and potential to ace Kickstarter)

#

if you put more effort making a better game, users will be more grateful. If you spend time making game modable, instead of making a better game, there is a good chance 3 people will be extremely happy, while potentially large userbase will be unhappy with the game itself, which will lead to a shorter lifespan and less monetary returns

#

again, talking from personal experience of lone developer

cloud cobalt Sep 19, 2016, 2:49 PM

#

We didn't spend any time on modding. Like I said, the game is moddable by design.

#

Like I said earlier, it depends on your game.

cerulean sequoia Sep 19, 2016, 2:51 PM

#

our game is build in a way that modding is basically just a click away, if the game is already supporting it, why not enable it?

vale silo Sep 19, 2016, 2:53 PM

#

UE4 isn't Quake... Quake was easy to mod. Nothing crazy about making sure users can access game data, package and distribute mods. UE4 is totally opposite. So, aren't you going to spend time figuring out how to make modding accessible ? It has nothing to do with your game moddable by design. It's about Engine not being modding friendly.

#

If UE4 was mod-friendly, I wouldn't even chime in 😃

cloud cobalt Sep 19, 2016, 2:54 PM

#

UE4 does have a modding pipeline, the difficulties seem to be licensing-related

#

Basically the "can't redistribute editor" thing

#

The only technical issue I outlined in my post is how DLC build will react to deleted content

#

Which is also a licensing issue

vale silo Sep 19, 2016, 2:56 PM

#

is there a clear and comprehensive docs about enabling UE4 game modding (and whatever needs to be accounted for when making UE4 game with modding in mind) ?

#

I recall asking about how to make sure released game and work with DLC and how to author DLC post-release, but I don't believe I ever got any response.

cloud cobalt Sep 19, 2016, 2:57 PM

#

Making a game with modding in mind has litte to do with Unreal, but we did it by using DataAssets extensively

#

So that any mod can override gameplay properties or add new content

#

Basically don't hardcode stuff in your code/Blueprint, use assets or external files to store data

#

Make the game modular so that one BP file can replace another

#

UT3 had extensive mod-specific logic in the code, for example

#

Every gameplay property was checked against 'mutators' objects

vale silo Sep 19, 2016, 3:02 PM

#

for example, in idTech based games, content is replaceable by simply providing pak file with higher number that the paks in original game. Let's say Doom 3 had assets007.pk4 as last number pak. If I make a replacement model for player and package it into assets008.pk4 (assuming folder structure and assets naming is identical inside virtual file system), player's model will automatically be replaced on load. How would that work in UE4 ?

#

Nowadays people don't give a damn about code. What they are more inclined to mod is visuals (skins, models, add new models/textures) and make new maps (using existing assets or mix of existing and new assets).

#

I recall none of these scenarios is documented officially

#

also there is a good chance one has to modify engine to allow such modding capacity

#

plz correct me if I am wrong

cloud cobalt Sep 19, 2016, 3:05 PM

#

Well my project is a space sim, which isn't a shooter, but I believe solutions would be similar

#

I'm pretty sure you can change a model in the editor and generate a patch that replaces the head in the base game

#

Or you can have a data asset like me, and at game start, list all PlayerHeadAssets so that the player can pick

#

Or you can iterate all blueprints with a name starting with PlayerHead

#

Just because the solution isn't a simple low-level file change doesn't mean it bad

#

And no, you don't need to modify the engine at all for this

#

The troubles lie with licensing, redistribution of content

#

btw I do give a damn about code, see my game's sources on Github 😃

vale silo Sep 19, 2016, 3:09 PM

#

well, it is bad if it's not obvious solution

#

nowadays it's all about convenience for users

#

if a users has to jump through hoops to get his/her model or textures into your game, it's not good

#

same goes for mapping

#

if a person can't launch editor and simply start mapping using your game's content, then it's a fail

cloud cobalt Sep 19, 2016, 3:11 PM

#

I agree about the mapping part, but like I said it's not a technical issue with the engine

vale silo Sep 19, 2016, 3:12 PM

#

so you are saying it's that easy to make maps for UE4-based games?

#

(assuming user signs up with Epic and gets Editor through launcher)

cloud cobalt Sep 19, 2016, 3:15 PM

#

it is easy

#

Assuming the developer provided the environment

#

Which is the root of my questions

vale silo Sep 19, 2016, 3:17 PM

#

what do you mean by "environment" in this case?

cloud cobalt Sep 19, 2016, 3:18 PM

#

In an ideal world, developers would be allowed to redistribute builds of UE4 editor

#

= what you are using right now (level editor, content browser etc)

#

UT3 did this, you just needed to start the editor executable, Steam even offered it at launch

#

When I say allowed, I'm really talking about legal fine print, not technical issues

#

You are not allowed to do it, so apparently you need to distribute your working directory (uproject file, sources, contents, config, etc)

#

Then people get UE, browse for your project, open it, and they have the same tools you do

#

Then they can generate a .pak file with all their modifications and release it

#

If you don't have marketplace assets or C++ source, that's it, nothing more

#

It's not complicated

#

If you do, see my forum post

vale silo Sep 19, 2016, 3:31 PM

#

well, but then users will have access to your BPs

#

sounds like a mess

#

what about replacing models, sounds, textures in UE4-based game ?

#

they don't really need your project

#

let's say you provide Content folder layout, specs and filenames for your assets you willing to allow to be replaceable

#

I assume end-user can sign in with Epic, get Ue4, create project with said Content folder layout, make a replacement model/sound/texture and author it into .ueasset

#

what's next ? how to actually package such mod, distribute it and how to use it with your game to see replacement in-game ?

#

how to make sure it can work with Steam Workshop ?

#

like I said earlier, idSoftware nailed it. It was extremely easy to distribute and use content mods (actually any mods) for Quake 1/2/3 and Doom 3

#

all that was required was downloading mod and dropping it into game's folder

cloud cobalt Sep 19, 2016, 3:39 PM

#

Are you sure you did modding with Unreal before ?

#

End user just needs to put MyMod.pak into GameDir/Mods

#

That's it

#

Steam Workshop does just that

vale silo Sep 19, 2016, 3:40 PM

#

for more elaborate mods (new content), mod content was placed into subfolder with distinct name and txt file (description.txt as I recall) containing mod's name. Engine would "see" that txt file, read mod's name from it and create menu item in the Mods menu. Bam!, that simple.

#

I never worked with UE until UE4

#

I am from opposite camp - idTech modder 😃

cloud cobalt Sep 19, 2016, 3:41 PM

#

You can do the same thing in Unreal

#

It's up to you as a developer

vale silo Sep 19, 2016, 3:42 PM

#

hmm.. sounds easy. Was it in UE3 only or is it how UE4 does it too ?

cloud cobalt Sep 19, 2016, 3:43 PM

#

UE3/UE4 provide a technical infrastructure to easily add or modify content, be it game logic, textures, models, behaviour trees, sound...

#

Some work is needed on it, as per my forum post about it

#

But I fail to see how you couldn't do the same thing

#

You can even hotload mods, apparently

vale silo Sep 19, 2016, 3:47 PM

#

so, is there comprehensive documentation about all that? tutorials ? (for devs - how to list mods in the game's Mod menu and load them; for end-users - how to author content mods for UE4 games)

cloud cobalt Sep 19, 2016, 3:48 PM

#

it doesn't works like that

#

There is a tutorial on how to generate DLC, you have to work from there

#

Listing stuff in your menus is highly game-specific

#

Mod authoring is even more game-specific

vale silo Sep 19, 2016, 3:49 PM

But there is no "the menu" in UE4. The menu is entirely up to the developer, some games don't even have one, some games do it with 3D widgets, some game use Scaleform, etc.

"Listing mods in the menu" is 100% outside UE4's responsibility as a game engine

#

simply saying modding capacity and support should be simple and documented, and bringing idTech as an example because that's what I worked with in the past, a lot.

#

Nowadays there is no competition when it comes to modding capacity, so there is no immediate incentive to improve.

#

and like I said earlier, only so many games benefit from offering modding capacity

#

I am sure Epic has a better grasp of the whole picture and if they aren't offering easy modding capacity, that simply means there isn't any benefit in it

#

if you are a large AAA-indie or AAA company, you have enough in-house resources to implement modding capacity on the low-level

cloud cobalt Sep 19, 2016, 5:23 PM

The low level side is absolutely not the issue in UE though.

vale silo Sep 19, 2016, 5:24 PM

If you are a lone indie or tiny indie team, chances that having modding will help to sell more copies or build massive following are low

well, when I get to it myself and find out it's really as easy as you say it it, then I will change my mind

right now it doesn't look like it's easy and worth investing time into

south ridge Sep 19, 2016, 9:56 PM

#

I have a general question

#

Hmm

#

It might be fitting to a different chat though

#

But I have a metro network - a large set of train tracks. There are signals on it

#

The signals work based on event system, so solving signals is very fast - the signals contribute zero tick time

#

But currently each signalling light is located in persistent level, while all actual visuals are in streamed levels

#

So outside of the levels, there's a large amount of floating signals

#

Should I change something about this?

#

Should I maybe separate the visual part of the signal & the logic part (so visual part is inside the level or something)? Though that would be pretty inconvenient

#

Do the actors floating outside of the level (when they are not inside the streamed chunk) contribute any considerable cost to stuff like occlusion culling etc

#

Should I possibly make them invisible when they are not in a loaded level

hollow dune Sep 19, 2016, 10:14 PM

not sure how you handle gamestate and all that, but since they are event driven (no tick time), and I don't know if they have to store values. I would honestly just keep them in the persistent and give them LOD2 that has 1 tris or something

frozen magnet Sep 19, 2016, 10:48 PM

#

@hollow dune if you rebuild the solution it does, if you just rebuild the project it will take longer than with non-source built engine, but not as long as recompiling the whole engine i think

hollow dune Sep 19, 2016, 10:51 PM

#

@frozen magnet Is there anything else I should be concerned with in regards to a source built engine? I do a build and despite I can see there are syntax errors, it's not identifying them and stating they are fine

frozen magnet Sep 19, 2016, 10:52 PM

#

is it causing it to fail to compile? which branch are you building?/

hollow dune Sep 19, 2016, 10:52 PM

#

I forked 4.13.0

#

the main one

#

Its not giving me a failure but I can see there are errors

#

the compiler just isn't complaining for some reason

#

which means I cant open the project because it fails to rebuild the .dll

frozen magnet Sep 19, 2016, 10:53 PM

#

main one as in release or master?

hollow dune Sep 19, 2016, 10:53 PM

#

master sorry

frozen magnet Sep 19, 2016, 10:53 PM

#

readme says master may not compile at any given time

#

try release

hollow dune Sep 19, 2016, 10:53 PM

#

ok, dammit

#

I don't even know if its worth it, the dam SQL support files it has look the dame same as this plugins, same name particularly gets me and the plugin won't run on droid

#

man UE4 should really work on mobile support, this is awful

When I unload a streamed level, a few actors are being left behind. How can I make sure my actors are going to be removed when my streamed level is unloaded?

hollow dune Sep 19, 2016, 10:58 PM

#

@agile wadi are the actors instantiated within the level that is unloaded?

agile wadi Sep 19, 2016, 10:58 PM

#

They're instantiated by other actors in that level.

hollow dune Sep 19, 2016, 10:59 PM

#

Im sure it will only unload the actors which are instantiated by that level

agile wadi Sep 19, 2016, 10:59 PM

#

As in actors that are actually in the level before runtime?

#

In that case I guess OnDestroy on those actors will need to cull anything they spawn.

hollow dune Sep 19, 2016, 11:00 PM

#

If you want to have a level that streams unload actors automatically you'll have to instantiate them through the level, if they're not the system will require you to manually remove them

agile wadi Sep 19, 2016, 11:00 PM

#

Right, cheers Null.

hollow dune Sep 19, 2016, 11:00 PM

#

All depends on how you build your system matey

south ridge Sep 19, 2016, 11:06 PM

#

@cerulean sequoia the signalling actors store some state related to signalling logic which AI trains read

#

(simply put, they store whether signal lights are lit or no)

#

So yeah, I'll just either make them invisible or give them a single triangle LOD so they are invisible in case an unthinkable happens and player manages to get a peek outside the level

#

hey guys, does anyone know how to possess a pre-placed character inside my level instead of spawning at the level start? Its always the default in the templates

marble lynx Sep 19, 2016, 11:53 PM

#

If you click on the character

#

type in possess in the details panel, there is an option to set a player to automatically possessi them on start and you just select which player to possess them

robust garnet Sep 19, 2016, 11:55 PM

#

ahhh found it. Strange, I was sure I searched for that last night, anyways thx!

agile wadi Sep 19, 2016, 11:58 PM

#

@robust garnet Another option is drag a reference to the actor placed in the level into the level blueprint and use player controller's posses node to posses that actor. Gives you a bit more control than the standard auto-posses.

robust garnet Sep 19, 2016, 11:59 PM

#

yeah that would be my second idea

agile wadi Sep 20, 2016, 12:12 AM

#

Does the Destroyed event not fire when a level unloads an actor? 😕

ashen brook Sep 20, 2016, 12:17 AM

#

probably not

#

you could use Event End Play for that

#

I think

agile wadi Sep 20, 2016, 12:17 AM

#

It doesn't seem to. Cheers will take a look.

is it automatic concat?

Since GameContentDir returns a FString

that's an operator override btw

For those interested I have a series of questions about modding here : https://forums.unrealengine.com/showthread.php?123419-How-can-I-release-a-modding-SDK-for-my-game

Hello,

After years of work, my game is nearing completion, and we've started taking a closer look at modding. Our title supports it on the technical side - we can detect and use mod content, assets can be replaced, etc. The game-specific part is all but done. The releasing and process issues appear to be much more complicated that anticipated, though. After much discussion on UnrealSlackers and this forum, some questions are still up in the air. Let's get to it :)

Not sure why the mod doesn't load though, that's probably an issue on my part

#

The world may never know ¯_(ツ)_/¯

cloud cobalt Sep 20, 2016, 9:20 AM

#

It will, when I get it to load

#

I mean the mod file looks OK

#

The game just forgot to load it ¯_(ツ)_/¯

#

The main issue is the near-complete lack of documentation, online discussions or tutorials

#

Sometimes it feels like no one has ever shipped a UE4 game, because you always find entry-level documentation, and precious little data on releasing, patching, etc

Hey guys! I'm sitting with one of those G25 Steering wheels, and I found a plugin earlier for it, but it's for UE 4.7 :/ What can I do?

according to your website the source code is included

Indeed it is included, @cerulean sequoia , didn't realise 😃

eager blade Sep 20, 2016, 9:57 AM

#

@tawny veldt There's also "Logitech Gaming SDKs" for free on the marketplace. It also contains support for Logitech's steering wheels.

If you don't need force feedback that UEJoystickPlugin might be good enough. Otherwise you're pretty much going to have to use Logitech's plugin.

@tawny veldt logitech SDK on marketplace is pretty much same thing as that old plugin that's around, with one key difference

it doesn't have any ue4 input mapping / bp support

so it's only usable from c++ directly as is

tawny veldt Sep 20, 2016, 1:40 PM

I read that earlier, and tried the joystick plugin instead

https://forums.unrealengine.com/showthread.php?70827-Logitech-G27-Plugin-available

Hi all,

i've made a Logitech G27 steering wheel plugin for UE 4.7.6, based on the one made by ENiKS (Thread).

It supports all buttons and input axes/sliders as input mappings and events in blueprints. All the force feedback functionality is exposed as well, programmable via Blueprints too.

You can find the source here: https://bitbucket.org/whiten01se/logitechg27plugin

One thing is worth noting: I didn't bother to implement a Win32 path for this plugin, but you can do that yourself

#

that's a better version of that 4.7 plugin

#

I've used these all on my g25

tawny veldt Sep 20, 2016, 1:41 PM

#

Hmmm..

cursive dirge Sep 20, 2016, 1:41 PM

#

currently just using the marketplace version but I've fixed it a bit

#

you get the source code with it too

tawny veldt Sep 20, 2016, 1:41 PM

#

So I should maybe try this one you linked

cursive dirge Sep 20, 2016, 1:42 PM

#

so you can manually keep it up with engine builds

#

basically since the implementations are so similar

tawny veldt Sep 20, 2016, 1:42 PM

#

the joystick plugin I just tried shows all the inputs, but they don't change when I do anything with the wheel

cursive dirge Sep 20, 2016, 1:42 PM

#

you could even take the marketplace plugin and merge the changes on that old plugin

#

they use same sdk after all

tawny veldt Sep 20, 2016, 1:43 PM

#

📎 unknown.png

cursive dirge Sep 20, 2016, 1:43 PM

#

yup, you won't get those with the marketplace asset alone

#

but it's just a wrapper

#

(that input mapipng thing)

#

you could also use the SDL based joystick plugin if you want

#

but you won't get as nice prebuild FFB things with it

tawny veldt Sep 20, 2016, 1:44 PM

#

That's the one I'm using

cursive dirge Sep 20, 2016, 1:44 PM

#

in fact, I'm not sure if it properly supports FFB even

#

does it do FFB?

tawny veldt Sep 20, 2016, 1:44 PM

#

FFB, is that force?

cursive dirge Sep 20, 2016, 1:44 PM

#

I know SDL itself implements that some way

#

yes, force feedback

tawny veldt Sep 20, 2016, 1:45 PM

#

It doesnt

#

That's what I read anyway

cursive dirge Sep 20, 2016, 1:45 PM

#

with logictech SDK you just give commands with functions that are selfexplanotary

#

it couldn't be much easier

#

(for forces)

tawny veldt Sep 20, 2016, 1:45 PM

#

Let's say I downloaded the one you linked me

cursive dirge Sep 20, 2016, 1:46 PM

#

it probably won't compile on 4.13 😄

tawny veldt Sep 20, 2016, 1:46 PM

#

.<

cursive dirge Sep 20, 2016, 1:46 PM

#

there's just been so many changes on c++ api

tawny veldt Sep 20, 2016, 1:46 PM

#

4.12 can do too

cursive dirge Sep 20, 2016, 1:46 PM

#

I think I've last used that on 4.9 myself

#

but I always update the api changes on my project so it's easier to maintain

#

this is the downside of not having proper joystick support built-in to ue4

#

someone still needs to keep the 3rd party plugins up-to-date

#

so you basically need to know some basic c++ stuff for it

tawny veldt Sep 20, 2016, 1:47 PM

#

Ok, then instead, let's say I just kept using this joystick plugin

#

would you know what I could do to make it actually grab these values properly? Because when I do a print string with any of these buttons, they never change

cursive dirge Sep 20, 2016, 2:09 PM

#

does any other input work?

#

on that same actor

#

like have you enabled the input for it

#

also possible that some plugins don't support hotreplugging controllers

#

so you could try to start the ue4 editor only after you've connected your wheel

#

I haven't used the SDL version of that joystick plugin

#

I initially tested the directinput version before someone ported it to sdl

grand python Sep 20, 2016, 2:22 PM

#

no. as actors

#

trees and stones

tawny veldt Sep 20, 2016, 2:22 PM

#

@cursive dirge I have just opened up a vehicle template project, and their inputs work fine, and I'm just adding the new ones in the same blueprint they're using. I have only started UE4 after the steering wheel was connected

grand python Sep 20, 2016, 2:24 PM

#

You could try adding the trees on the cunks and then save those chunks with the trees on it as a BP

#

and then spawn those BPs in your runner BP

#

like you do with the landscapes

humble lark Sep 20, 2016, 2:24 PM

#

@grand python Adding the trees on the chunks in the level editor?

grand python Sep 20, 2016, 2:24 PM

#

yep

#

then save that as a own BP

cursive dirge Sep 20, 2016, 2:25 PM

#

@tawny veldt yeah, I dunno, I'd check the plugins docs first

#

like how it should be setup

#

there could be some init somewhere

humble lark Sep 20, 2016, 2:25 PM

#

I can't seem to find the instance of the foliage that was generated with the tool

tawny veldt Sep 20, 2016, 2:26 PM

#

It only tells you how to install it, and then says.. "Now you can map Inputs to Joystick devices in Project Settings. (Engine->Input)"

grand python Sep 20, 2016, 2:26 PM

#

hm. Sorry cant help you with that then. i'm just a beginner too :P

humble lark Sep 20, 2016, 2:27 PM

#

@grand python Ah, well thanks for the help so far... I even tried making the trees in blender, but now I'm having so many problems with light UV mapping

grand python Sep 20, 2016, 2:28 PM

#

Yea best is to add them manually like you added the landscapes

tawny veldt Sep 20, 2016, 2:29 PM

#

@cursive dirge I'm starting to think maybe the solution is to just see if I can somehow get the plugin you linked to work >.>

grand python Sep 20, 2016, 2:29 PM

#

hm.. i'm thinking of a way that works with raycasts. and places trees on the hit points

humble lark Sep 20, 2016, 2:29 PM

#

That's pretty much impractical since I need lots and lots of foliage

#

It can't be any type of blueprint spawning. That would kill the performance 😦

#

Aside from the chunk spawning that is. They need to be complete as a whole for it to be playable on a mobile I think

tawny veldt Sep 20, 2016, 2:57 PM

#

@cursive dirge Okay, I think I figured it out. 4.13 doesn't like the plugin, but 4.12 is fine 😄 Except, it tries to normalize the values to -1 and 1, but they still jump around to -4 and 4 while turning the wheels

cursive dirge Sep 20, 2016, 3:00 PM

#

ah

#

I'd check the warning on 4.13

#

they may give hints why it doesn't work properly there

cerulean sequoia Sep 20, 2016, 4:02 PM

#

@tawny veldt you could just clamp the values to -1 +1 so that those spikes don't matter anymore xP

tawny veldt Sep 20, 2016, 4:02 PM

#

@cerulean sequoia <3 I'll try that first thing tomorrow :D

tough kayak Sep 20, 2016, 5:03 PM

#

Anyone know how I can change everything in my project to UV source channel 1 instead of 0

#

A bunch of the objects I imported have bad uv mapping and some of them keep going back to chanel 0

limpid phoenix Sep 20, 2016, 10:38 PM

#

So can you not make a spawnable level sequence that is in local space? I can't seem to find anything about this kind of usage

safe rose Sep 21, 2016, 12:19 AM

#

@tough kayak go into the mesh editor and change it

tough kayak Sep 21, 2016, 12:19 AM

#

Victor!

#

Thanks, I'll give it a go tomorrow at the office

safe rose Sep 21, 2016, 12:19 AM

#

np

cursive dirge Sep 21, 2016, 1:40 AM

#

@tough kayak you can also pick the UV source on "TextureCoordinate" node on individual materials

#

not a project wide setting though

plush yew Sep 21, 2016, 7:29 AM

#

Anybody knows if theres a way to get the scale for each instance from instnaced static mesh

#

in the material editor?

#

?

cerulean sequoia Sep 21, 2016, 7:52 AM

#

@tough kayak you can probably save you some time and change those uv channels via the property matrix, could be exposed there

hollow dune Sep 21, 2016, 10:23 AM

I can't find a c++ version of this delegate, does one even exist because I can't find one in the API docs. https://docs.unrealengine.com/latest/INT/BlueprintAPI/EventDispatchers/ApplicationWillEnterBackgroundDe-/index.html

with a 3 Param

Trying to fire up Steam, having fun trying to debug it

#

I wish they wouldn't change core engine features like the OnlineSubsystem without updating the docs

#

That just makes me sad 😦

plush yew Sep 21, 2016, 2:28 PM

#

Yeah, I've never understood the habit they have at epic of updating core features and updating documents months later.
Why not release the update some weeks later then planned if it would give them enough time to write and post docs

fossil socket Sep 21, 2016, 3:40 PM

#

also you'll learn very quickly that the steam online subsystem implementation sucks

#

and for some reason you can't use the ipnetdrv with it? i haven't found a way that works, right now we're using the steam net driver which uses steam's p2p networking lib and you can't join servers by direct IP

feral dirge Sep 21, 2016, 4:25 PM

#

Yeah but that's easy to get around

#

You can use a Master Server and an alt subsystem and all that shit

foggy valley Sep 22, 2016, 2:40 AM

not UE lightmass though, it all ends up in a parameter in the material

#

writing to the actual level lightmaps is in the future

candid smelt Sep 22, 2016, 2:42 AM

#

if i was buying/building a new PC for UE4 dev, am i better off looking at a faster quad core processor, or a "slower" hexcore or above? for example, a 6700K vs 6800K?

foggy valley Sep 22, 2016, 2:43 AM

#

go haswell, get 12 threads

#

I have found it to be real good

#

in general 8 threads is a bit limiting and 12 is fine

candid smelt Sep 22, 2016, 2:44 AM

#

i'm finding that at the moment, i'm running a i7-4770 with 16gb ram, ram isn't getting smashed too hard, but the processor is struggling a bit

#

the editor scales nicely with more cores tho?

upbeat fern Sep 22, 2016, 3:33 AM

@candid smelt seems fine on a i7-4930k not sure on the spec diff.

Hi there. I'm using the Profiler for the first time to optimize my project. How can I identify the big bugbears? Is it just the "Inc Time" in ms? Is this the correct spot to ask this question?

kindred viper Sep 22, 2016, 9:24 AM

#

I just usually follow the chain of the highest milliseconds, follow the red, identify the trouble function or line and go from there. It's all a bit of a mystery except for a few key parts. Kind of a specialised deal.

@dark pike concept art of some level prototype?

well try to stick to it, you wanted your cave to be giant ass

dark pike Sep 22, 2016, 9:45 AM

I see what you did there

foggy valley Sep 22, 2016, 9:45 AM

#

so what are you modelling in?

dark pike Sep 22, 2016, 9:46 AM

#

Blender.

cursive dirge Sep 22, 2016, 9:46 AM

#

why you want concept art?

#

like you want to become concept artist?

foggy valley Sep 22, 2016, 9:47 AM

#

I don;'t know blender at all

#

naw he wants to model one

#

he's having trouble with modelling concepts

#

the concepts of modelling

cursive dirge Sep 22, 2016, 9:47 AM

#

well, people still use real 3D models as part of concept art too

#

oh

#

well

#

step one

#

google for image references

#

find something that looks like what you want to do

#

to get the feel of the scale and shapes

foggy valley Sep 22, 2016, 9:48 AM

#

yeah I'd make a subdivided tube and distort the crap out of it

#

then add in ledges and shit

#

caves are unforgiving, there is no consistent scale to a cave

cursive dirge Sep 22, 2016, 9:48 AM

#

if you don't know what it should look like, it'll not look good

#

well, details still should have some believable scale

#

unless it's some low poly or artsy kinda environment

dark pike Sep 22, 2016, 9:49 AM

#

No.

#

I just... dont know if i should do it in parts then glue it together. Or do it in one big heap.

#

I tried foing one big heap, but then it got really irritating.

you could do the walls as bigger chunks if you want

But, thanks

I think i have the idea

cursive dirge Sep 22, 2016, 10:15 AM

#

well, simplest wall is just a plane you flat subdivide, curve it a bit and add noise to it

#

that takes like two minutes in modo, you'd think blender can do those things too

#

that'll not be modular though, but you get the idea

cursive dirge Sep 22, 2016, 10:35 AM

hmmmm

#

I'm looking at unreal c++ api docs

#

I was going to write a post on the forums about it

#

I took a peek on unity's camera docs

#

and unreals

#

https://docs.unrealengine.com/latest/INT/API/Runtime/Engine/Camera/UCameraComponent/index.html

#

for example, "GetCameraView" on that page has description "End of UObject interface."

#

like, what?

#

also 1/3 of listed items don't have any description

#

only the most obvious ones have been explained

#

or, well, I guess those rest are pretty obvious to most too

#

besides ResetProxyMeshTransform and RestoreFrustumColor :p

cloud cobalt Sep 22, 2016, 10:39 AM

#

Unreal has a big documentation issue

cursive dirge Sep 22, 2016, 10:39 AM

#

yeah

#

I've talked with Lauren about c++ api docs, she wanted me to point out some inidivdual places where the docs were bad

#

but it's not just individual place, it's basically the whole c++ api doc

#

most of the other docs are fine

cloud cobalt Sep 22, 2016, 10:40 AM

#

On some level it's understandable, it's hard to define when a class is an internal or public-facing

#

But the camera component -_-

cursive dirge Sep 22, 2016, 10:40 AM

#

also, they list some new things as DEPRECATED

#

not on that class

#

that's mainly some scripting issue when they parse these things

#

but the bottom line is, that these descriptions are not consistent

#

if you look the main level description

cloud cobalt Sep 22, 2016, 10:41 AM

#

OnComponentDestroyed
Called when a component is destroyed

cursive dirge Sep 22, 2016, 10:41 AM

#

and then open the function etc

cloud cobalt Sep 22, 2016, 10:41 AM

#

^ oO u dont say

cursive dirge Sep 22, 2016, 10:41 AM

#

it can have totally different text

#

heh

#

that's my favourite example when I describe why the api docs are bad

#

they usually just point out the obvious

#

at least on things that are not really basic

#

that camera component is bit bad example about it

#

as it's still better documented than most o the things I've seen

#

I also lol'd a bit at this page

#

https://docs.unrealengine.com/latest/INT/API/Runtime/Engine/Camera/index.html

#

on half of the items

cloud cobalt Sep 22, 2016, 10:44 AM

#

The latest thing I started in UE is modding support, and it's amazing how there is close to zero documentation & support.

cursive dirge Sep 22, 2016, 10:45 AM

#

well, have you checked docs how unreal implements physics or multiplayer prediction?

#

they only tell the higher level things on generic docs

cloud cobalt Sep 22, 2016, 10:45 AM

#

Multiplayer was extremely well documented on UDK, so that's surprising

cursive dirge Sep 22, 2016, 10:45 AM

#

I haven't seen a single page on official docs that tell that only character class has multiplayer prediction built in

#

and no page describing how the prediction even works

cloud cobalt Sep 22, 2016, 10:46 AM

#

Physics are done by third-party code so it's less shocking, plus Unreal generally sucks at physics (physics-based game dev here)

cursive dirge Sep 22, 2016, 10:46 AM

#

oh

#

I mainly meant, there's no docs that describe how unreal implements the physx integration

#

most of the ue4 devs I've talked with don't even know physics get calculated by default once per tick

#

nor understand why it's bad

#

on unreal that is

#

Unity actually ticks physics at fixed steps

#

with same physics engine

#

there's also hidden functionality on physics side, like ability to run custom physics code on substeps which isn't documented anywhere

#

substepping itself is mentioned on few pages though

cloud cobalt Sep 22, 2016, 10:49 AM

#

UE has substepping support though

cursive dirge Sep 22, 2016, 10:49 AM

#

yeah, but even that is still tied to framerates

#

it just adds extra physics steps if frame rates go low

#

the whole logic how it calculates it is also usually hard to explain, due to the way it's implemented

#

there are lots of conditions

#

btw

#

there used to be a good doc page how unreals character networking code worked

#

it was on the old site

#

many webpages actually link to it

#

but it doesn't exist anymore

cloud cobalt Sep 22, 2016, 10:53 AM

#

Yeah I know that page

#

Anyway, my general takeway is that UE4 is the best engine for large-scale games with classic technology

#

Like doing a shooter

#

Or a race game or...

cursive dirge Sep 22, 2016, 10:54 AM

#

well, racing game is hard

#

as it involves physics 😄

#

and that's pretty messed up on unreal

cloud cobalt Sep 22, 2016, 10:54 AM

#

Yeah but you can get away with it I think, it's not like realism is super essential in most race sims

cursive dirge Sep 22, 2016, 10:54 AM

#

if you do like single / local co-op game, it's ok

foggy valley Sep 22, 2016, 10:54 AM

#

it's a game framework. you can use as much or as little of it as you like

#

you can treat it like a graphics engine if you want

cursive dirge Sep 22, 2016, 10:54 AM

#

as you don't have to run the same simulation on other computers

#

@foggy valley that's pretty much what I do atm

foggy valley Sep 22, 2016, 10:55 AM

#

there you go then 😄

cursive dirge Sep 22, 2016, 10:55 AM

#

I replace unreals input system, physics calculations etc 😄

cloud cobalt Sep 22, 2016, 10:55 AM

#

UE starts to fail when you want to do something really out of the box

#

Because it's very much a rigid, monolithic system

cursive dirge Sep 22, 2016, 10:55 AM

#

I really wish they didn't hardcode some of the stuff in the engine

#

the input thing kinda pisses me off tbh

#

for example

foggy valley Sep 22, 2016, 10:56 AM

#

I want to say that it's not that monolithic

cursive dirge Sep 22, 2016, 10:56 AM

#

by design

foggy valley Sep 22, 2016, 10:56 AM

#

but I guess it is

#

input thing?

cursive dirge Sep 22, 2016, 10:56 AM

#

you can't do local splitscreen that would use keyboard + gamepad

#

as unreal hardcodes that keyboard and first controller is always player 1

foggy valley Sep 22, 2016, 10:56 AM

#

a non-monolithic game engine would be incredibly hard to debug

#

ah I see

#

yeah that's crap

cursive dirge Sep 22, 2016, 10:56 AM

#

you need to have two controllers to do local splitscreen

cloud cobalt Sep 22, 2016, 10:56 AM

#

The rendering pipeline is definitely an immovable, giant unhackable rock, and at some point it can be an issue

cursive dirge Sep 22, 2016, 10:56 AM

#

also

foggy valley Sep 22, 2016, 10:57 AM

#

fix it and make a pull request? 😄

cursive dirge Sep 22, 2016, 10:57 AM

#

builtin input system doesn't support anything but xinput and steam controller

foggy valley Sep 22, 2016, 10:57 AM

#

the RHI is getting heavily modified soon

cursive dirge Sep 22, 2016, 10:57 AM

#

so if you have directinput device

cloud cobalt Sep 22, 2016, 10:57 AM

#

You can't fix the architecture :/

foggy valley Sep 22, 2016, 10:57 AM

#

it won't be so bad then

cursive dirge Sep 22, 2016, 10:57 AM

#

like steering wheel, flight stick etc

#

you have to use 3rd party plugin

#

and then you'll get all kinda of mapping issues with the splitscreen thing to

#

I just replaced the whole thing myself

cloud cobalt Sep 22, 2016, 10:58 AM

#

@foggy valley One piece of example is how you can't exclude objects from AA in the scene

cursive dirge Sep 22, 2016, 10:58 AM

#

also

#

splitscreen is also hardcoded

#

you add a player

#

you get splitscreen

#

local player that is

#

you don't have much control over the viewports

#

3 player splitscreen is forced to have one bigger view and 2 smaller ones

#

you can't like split the screen in 3

foggy valley Sep 22, 2016, 10:59 AM

#

I don't know enough about deferred rendering in UE to know if the AA is unreasonable or not

#

but I would like to see MSAA

cursive dirge Sep 22, 2016, 11:00 AM

#

MSAA works on 4.14 and forward

cloud cobalt Sep 22, 2016, 11:00 AM

#

@cursive dirge You can probably use your own viewport subclass

cursive dirge Sep 22, 2016, 11:00 AM

#

I've used it

foggy valley Sep 22, 2016, 11:00 AM

#

hmm yeah this all sounds like shit

#

let's switch to unity and spend ten years writing the features we wanted from unreal 😉

#

it's a trade-off

cursive dirge Sep 22, 2016, 11:00 AM

#

@cloud cobalt sure you can mod the engine

cloud cobalt Sep 22, 2016, 11:00 AM

#

@foggy valley MSAA is only on forward, isn't it ?

foggy valley Sep 22, 2016, 11:00 AM
