It's for university coursework, we have to make a game and a quick level using BSPs. We're not being graded on models / textures

#

The coursework is to create a game in C++ but just quickly make a level in BSP to give it life

plush yew Oct 7, 2016, 9:27 PM

#

Ok well remeber to convert the BSPs to meshes if you want to save on performance costs later

worn merlin Oct 7, 2016, 9:27 PM

#

Yeah will do

#

just using them for now so I can do rooms easily

#

subtract boxes inside boxes etc.

#

Do you know how to make the bsp brushes update in realtime?

#

actually

#

nevermind

#

BSP brushes don't update my NavMesh

#

Back to static meshes

plush yew Oct 7, 2016, 9:32 PM

#

what kind of static meshes do you need?

worn merlin Oct 7, 2016, 9:44 PM

#

Just basic buildings that I can walk in, some with upstairs

#

Can be any static mesh really, to populate an outdoor scene

plush yew Oct 7, 2016, 9:54 PM

#

You could use hammer level editor and import it into unreal

#

or you could use the "Architecture" meshes in the contentbrowser and build a scene, wall after wall/floortile after floortile

worn merlin Oct 7, 2016, 9:58 PM

#

Where about are the Architecture meshes

plush yew Oct 7, 2016, 10:20 PM

Still here?

#

They should be in a subfolder of the Startcontent folder

As you can see, it's quite versatile, and you can merge a set of meshes together to become a single mesh using teh merge mesh tool also

worn merlin Oct 7, 2016, 10:25 PM

#

Oh sweet

#

I've never used starter content before, always used plain C++ no starter

#

I can just create a new blank BP project and migrate the architechture folder over, right?

plush yew Oct 8, 2016, 5:26 PM

#

@keen pine I would check if your surface is horizontal. Maybe it isn't and the engine thinks therefore that the falling doesn't have to stop yet?

half basalt Oct 9, 2016, 2:29 PM

#

Hi guys, hows it going?

#

I need a bit of help. Ive googled and it seems people have probably asked this question a bunch but a lot of the topics were from a year ago or more. Hoping somethings been done and im just stupid.

So, Unity has a function in the camera to allow you to set the viewport rect. Basically to allow you to choose where the game renders within the relative window, what aspect ratio etc. It also now allows you to pick which display each camera renders to.

In Unity, this allows me to create 4 cameras, set them all to display one and set each cameras position and size.

The reason I need this is because the project im working on is outputting one image and then using a video mixer of sorts, taking parts of the image and outputting it to different monitors or projectors. It's not a full game we are doing, just something small, and as such we are actually outputting one 3840 x 2160 image, and dividing the image into 4 parts.
One is 3840 x 1180, the rest are other sizes. In total it basically uses the entire 4K image and outputs each bit to the desired screen.

Is there any way to do this right now? The closest i could get, but it seems REALLY heavy and like a shitty workaround is to make a widget blueprint, set the screen size to 3840 x 2160, place a bunch of images, do targer renders, convert to a material and place the material on the images inside the widget.

#

So ill have 1 scene, 4 characters, one background and the characters move around on this stage. 4 target render cameras each with the image resolution set correctly

#

(rebuilt the engine to allow for larger resolution render targets)

#

Be really good if there was a way or an engine mod that allowed me to do this.

Watched Carmack's OC3 closing keynote and he asserted that long loading times is a very bad thing for Gear VR apps (long loading time can be a big turn off for users and I bet Oculus can even not let the app on the store due to loading times).

UE4 is notoriously slow when it comes to loading on Gear VR (development builds for sure) :(

What tricks are available to ensure shorter loading times? (project settings, etc.)

@half basalt Yes

For now, look up render targets and render textures. Then create a UMG grid and put them up as a UMG

half basalt Oct 9, 2016, 4:30 PM

#

Yeah thats what I've done!

#

so far

#

4 render targets with 4 render textures

#

and set up a UMG grid

#

each render texture is set to its resolution (for example 3840 x 1180), put in the correct position. Seems to work but wasnt sure how heavy it is

#

ill take a screenshot...

@feral dirge is that what you meant? 😃

feral dirge Oct 9, 2016, 5:21 PM

3840 x 4 is mental lol

half basalt Oct 9, 2016, 5:27 PM

#

its not 3840x4 😛

#

its one 3840 image

#

Top part with the 4 girls is 3840 x 1152
left vertical is 1150 x 567 (blond girl)
right vertical is 1150 x 567 (other girl)
bottom right is 2540 x 1008 (shadows)

#

total amount of pixels will fit within a 3840 x 2160 image

#

Only going to be having a maximum of 4-6 characters on stage, with a medium density performance stage

#

Anyway, how performance intensive is going this way? Going through unity I can get about 100 fps with the same setup... Toon shader, 4 lights, same resolution

#

maybe 160 but our setup isnt fixed yet

#

Planning to add an outline post processing effect, hope that will be possible

feral dirge Oct 9, 2016, 5:36 PM

#

Yes, it's performance intensive, no idea how intensive, that are various things you can do obviously to aleviate some of the issues

unity cameras are much better than ue4

#

unity doesn't have to go through render targets as much

#

ue4 does

best bet: rewrite ue4 renderer

For best performance

@half basalt 4 separate render targets and composition into single image using post-process would be the easiest

#

basically what you do already

#

but I think some post-processes didn't work on render-targets and you can sample only non HDR

#

at least it worked only with LDR for me in 4.12

half basalt Oct 10, 2016, 5:15 AM

#

In doing that though, am I rendering the same scene 5 times?

#

also yeah, we need outlines too for the anime look

vale osprey Oct 10, 2016, 5:16 AM

#

you would do that anyway with multiple cameras

half basalt Oct 10, 2016, 5:16 AM

Well obviously if i had 4 cameras i would be rendering it 4 times i thought, not 5 times

if you place a box in front of camera and place camera somewhere out of bounds of the level it should be fine

fallen schooner Oct 10, 2016, 5:18 AM

vale osprey Oct 10, 2016, 5:19 AM

#

@half basalt the best would be to actually change rendering pipeline and render all separate cameras into the same main g-buffer

#

yeah, RHI - rendering hardware interface

#

it's a part of the engine where you can define pipeline yourselve, but I don't think it's easy to do, plus most likely there is a ton of optimization in regards to specifi camera bounds. Like where the light are and etc

half basalt Oct 10, 2016, 5:21 AM

#

cool! Thank you! any idea how long it would take a small team of programmers (3 or 4 people) to go in and make these sorts of adjustments?

Although UE4 is great in many ways I feel like it is lacking for stylized/non-photo real rendering. To remedy this (and to better learn how UE4's deferred shading system works internally) I have been working on a toon shading model that should allow for a greater range of visual styles while seamlessly integrating with the rest of the rendering system.

Here's a screenshot of some of the features that work

Ever since UE4 was released over two years ago, people have been complaining about the shader extensibility problem. The material editor is very limited and should never have completely replaced HLSL shader coding like it does now. There are too many things it can't do:

It can't do new shading models that react to UE4's lights
It can't do geometry shaders
It can't do multi-pass shaders
It can't do compute shaders

Normally you do a raytrace from the muzzle to the crosshairs but with a shotgun you add some arbitrary spread to the trace. The problem is that spread is the same at all distances.

Hi y'all: Quick question about moving shadows with animated trees: I have a scene with a directional light (for the sun), a static building and animated trees. When I bake the lighting, the shadows from the moving trees are also baked. What should I change so that the tree shadows are always animated? (light is set to 'Stationary' atm)

iirc, UE blends between static and dynamic shadows in this cases depending on distance from the camera

@shell nimbus - send me the max file if you like and I'll take a look here

shell nimbus Oct 10, 2016, 11:19 AM

#

ok

sleek leaf Oct 10, 2016, 11:19 AM

#

out of curiosity, is your MultiSub applied to the whole mesh?

#

you've not accidentally applied the mulitsub to SOME of it, and the individual materials to the rest, have you?

shell nimbus Oct 10, 2016, 11:20 AM

#

no material created yet. max 2016

unhide all to see all scene. only curved glass ( on video ) mesh has this problem

looking at it now

#

were you using Material ID's?

shell nimbus Oct 10, 2016, 11:23 AM

#

yes

sleek leaf Oct 10, 2016, 11:23 AM

#

its all using MatID 1 on my end

shell nimbus Oct 10, 2016, 11:23 AM

#

i create them for each try

#

so its raw version

#

1- just give material id 2 - 3 for some polygons.
2- assign multy sub with some colors like in video
3- import to ue4 ( tested 4.12 and 4.13 = same bug )

sleek leaf Oct 10, 2016, 11:24 AM

#

mmmm :S that's how i do my MultiSub stuff

#

should work

shell nimbus Oct 10, 2016, 11:25 AM

#

if it works for you i will break my pc

sleek leaf Oct 10, 2016, 11:25 AM

#

see if @fresh merlin comes back with the same issue, all your polys came out as MatID 1 to me matey

#

sorry 😦

#

nah its broke here too

shell nimbus Oct 10, 2016, 11:25 AM

no dude look at the top polygons

#

i show in video

i've had worse issues with work, once spent 3 hours fixing bugs in a java code (we wernt allowed to use an IDE at the time, all notepad)

any other tool for reset ?

ok - you are using Corona. I need to convert to a vray scene first

shell nimbus Oct 10, 2016, 11:30 AM

#

true but its still a global polygon modellinmg

#

am i wrong?

vale osprey Oct 10, 2016, 11:30 AM

#

@shell nimbus how did you mapped it in max?

fresh merlin Oct 10, 2016, 11:30 AM

#

Font and back faces, bottom edge and side edges are all ID 1

#

Top endge is ID 2

shell nimbus Oct 10, 2016, 11:31 AM

#

111x111x111 uvw mapping for all arcviz meshes

#

i think its not related with material id ( elemets )

vale osprey Oct 10, 2016, 11:31 AM

#

ok, and then you assigned materials by IDs?

#

maybe you get a double polyogon there during import

shell nimbus Oct 10, 2016, 11:32 AM

#

hmm.. interesting ideas

vale osprey Oct 10, 2016, 11:33 AM

#

sometime mapping didn't worked for me until I collapse stack and turn in into editable poly or editable mesh

#

can you count triangles in editor in UE4?

#

just to be sure

shell nimbus Oct 10, 2016, 11:33 AM

#

on it

fresh merlin Oct 10, 2016, 11:34 AM

#

When I open your scene in Max, there isn't a material assigned to the geometry. It could be because I don't use Corona (only VRay), but I would have expected to see different IDs to the different colours you want.

shell nimbus Oct 10, 2016, 11:34 AM

#

152 polygons on max and 204 tris on ue4

create a multy sub

Who uses editable mesh these days???

dude i gonna cry

#

and only this mesh effected for no reason

fresh merlin Oct 10, 2016, 11:46 AM

#

I just converted to mesh then back to poly and it works just fine. How did you create the geometry? Was it imported from somewhere?

vale osprey Oct 10, 2016, 11:46 AM

#

it must be "baking" material ID

#

I had to do this sometimes to fix other bugs

fresh merlin Oct 10, 2016, 11:47 AM

#

@shell nimbus where did you create the 3d model in the first place?

shell nimbus Oct 10, 2016, 11:47 AM

#

convert to edit mesh and convert back to edit poly and everything is ok

#

extrude the spline

I get a lot of warning about degenerate tangents but in 99,9% cases everything works fine

#

it just doesn't like Cap operation on outlines

#

but sometime, it inverts polygons

cursive dirge Oct 10, 2016, 4:19 PM

#

@BoredEngineer#0100 I think you get that warning sometimes when your uv's are messed up or missing too

#

@BoredEngineer#0100

#

@leaden harness do you know what's up with the tagging?

#

it breaks really often

#

and when it breaks, it just breaks for specific users

#

I haven't figured out what's the core issue

#

like for example, @vale osprey seem to be offline atm, but can't tell anything else that would be out of ordinary

#

and...

#

it works now again

#

doesn't matter if I use "Mention" or just type @ and use autocomplete

leaden harness Oct 10, 2016, 4:26 PM

#

@cursive dirge nope, not sure what might be wrong

#

Maybe typing it like @cursive dirge is broken?

#

nope

#

I dunno ¯_(ツ)_/¯

#

Works on my machine :-p

cursive dirge Oct 10, 2016, 4:29 PM

#

yeah, it seems to work now again

#

but it's occasionally just totally broken for some users

#

it then starts working again a while later

leaden harness Oct 10, 2016, 4:30 PM

#

Maybe something is broken with mentioning offline users

cursive dirge Oct 10, 2016, 4:30 PM

#

@vale osprey just testing, sorry about this ;D

#

well

#

boredengineer is still offline

#

so I dunno

#

I literally did the tagging same way and different way and it just didn't work initially

#

you can see the test I wrote there

#

there's nothing wrong with the text form

#

it just fails to capture the user sometimes

#

it can also break on desktop client and mobile client so it's not client specific thing

vale osprey Oct 10, 2016, 4:33 PM

#

@cursive dirge no worries 😃

cursive dirge Oct 10, 2016, 4:34 PM

#

since you are here though, does the tagging ever break for you?

vale osprey Oct 10, 2016, 4:34 PM

#

You are right, I don't think I've even mapped most of those meshes

#

Seen it ones I think

cursive dirge Oct 10, 2016, 4:35 PM

#

it happens like once a week for me

#

and it keeps missing the tags for the same user

#

if I tag some other user it still works

bleak copper Oct 11, 2016, 1:47 AM

#

Hmm... so is there a way to allow PlayerStarts to overlap with collidable objects, to spawn pawns (ie: free-floating cameras) that themselves have no collision?

#

Like, a flag that says "don't check collision, I guarantee that I'll only be spawning noclip pawns".

#

If no-one knows off-hand, I could check the source later.

keen pine Oct 11, 2016, 4:30 AM

#

@bleak copper just make a blueprint and make yur own spawner that has colliders etc

#

if I read what you're asking correctly

bleak copper Oct 11, 2016, 4:31 AM

#

Not sure what you're saying.

I'm talking about surpressing "Bad Size".

#

does anyone know how to make exponential height fog get darker the deeper you go?

bleak copper Oct 11, 2016, 6:02 AM

#

Don't think you can vary the color of Exponential Height Fog

#

Could it be done in a postprocess material by using the scene depth buffer?

fresh merlin Oct 11, 2016, 7:52 AM

#

Good morning all. I just watched a UE training video on material instancing where the presenter showed how instances of materials are essentially 'free' when it comes to compiling. He ended up using a metallic material as the parent, but creating 2 completely different instance materials from this: one was brick and one was copper.
If you can create such different instanced mats from a parent, why isn't EVERY material an instance regardless if they are 'free'?

frank escarp Oct 11, 2016, 7:53 AM

#

the node graph has to be compiled

#

while the instance variables are just variables that are tweaked

#

the graph is like a program

#

while the instance variables are just the default properties of that program

#

and they are not free lol

fresh merlin Oct 11, 2016, 7:54 AM

#

But he seemed to suggest that you get far more interactivity with the viewport if you tweek instances rather than main materials all the time

frank escarp Oct 11, 2016, 7:54 AM

#

the main purpose its to have "supershaders"

#

yes, that is true

#

the system is made so you can have your tech artist do shaders with cool FX and stuff

#

and then the artist just has to come, plug the texture maps, and tweak one or 2 variables

cloud cobalt Oct 11, 2016, 7:55 AM

#

At some point the graph needs to be compiled as a binary program that runs on the GPU

#

That takes a few seconds / minuteq

#

Then, every program can have parameters

#

Material instances are just a set of presets to this program

#

Setting a variable is obviously pretty much free

#

To answer the question : you can definitely do one material for your entire game and just use material instances

fresh merlin Oct 11, 2016, 7:56 AM

#

I see...I think.

frank escarp Oct 11, 2016, 7:57 AM

#

materials with static switches do have to be recompiled in instances

fresh merlin Oct 11, 2016, 7:57 AM

#

Thanks guys

cloud cobalt Oct 11, 2016, 7:57 AM

#

It's just not usually worth it

#

If you're going to have 50 rock meshes, one master rock material makes a lot of sense

frank escarp Oct 11, 2016, 7:57 AM

#

learning a bit about opengl/directX shaders goes a really long way to understand how the engine works

fresh merlin Oct 11, 2016, 7:58 AM

#

I'm very familiar with creating materials in 3dsmax/vray. UE4 is quite different. I could do with a basic library to look at/study/use/copy ideally.

#

(just architectural type stuff really)

frank escarp Oct 11, 2016, 7:59 AM

#

becouse 3dsmax is using "prebuilt" materials

#

just edits some variables

#

they also have a nodal system now, no?

#

main difference is that those run on CPU, while ue4 ones are GPU

fresh merlin Oct 11, 2016, 7:59 AM

#

Yes, they do. I'm pretty old skool, but the slate editer is node based.

cloud cobalt Oct 11, 2016, 8:01 AM

#

Rendering in classic 3D vs real-time is usually quite different

frank escarp Oct 11, 2016, 8:01 AM

#

classic 3d uses "true" PBR

#

as its a pathtracer and things like that

#

ue4 is an aproximation of that

#

a pathtracer works on a BRDF, wich, simplified, its a probability function for where is the ray going to bounce

cloud cobalt Oct 11, 2016, 8:02 AM

#

Yes, but more than that, classic 3D usually uses "automatic" materials

fresh merlin Oct 11, 2016, 8:02 AM

#

Its pretty amazing and I'm enjoying the learning. Quite a lot to take in!

cloud cobalt Oct 11, 2016, 8:02 AM

#

Real-time relies on custom textures for each object

frank escarp Oct 11, 2016, 8:03 AM

#

classic 3d also depends

#

on Cycles, blender, you have a nodal editor that works directly on the brdf

#

you merge different shaders, like a gloss shader with a diffuse shader, or with a fresnel

fresh merlin Oct 11, 2016, 8:04 AM

#

Here's a very basic question: in order to use a StarterContent material in my own project, do I first need to create a new project with the starter content included in order to migrate particular mats that I like, or can I 'import' materials directly into my own project by navigating to somewhere specific?

frank escarp Oct 11, 2016, 8:05 AM

#

you can migrate

#

go to another project wich has the pack

#

click the assets you want

#

select "asset actions -> Migrate"

#

careful, that uses the dependencies

#

so it can bring a ton of stuff

fresh merlin Oct 11, 2016, 8:06 AM

#

So I do need to create a project with the pack first? It seems a bit weird/wasteful.

#

(a separate project I mean: one purely for 'harvesting' assets)

bleak copper Oct 11, 2016, 8:14 AM

#

But yeah

fresh merlin Oct 11, 2016, 8:14 AM

#

Scenario: say I've found a nice cobble material in the StarterContent, and I want to use it in my own scene on a large floor surface. If I apply this material to my large floor surface, the scaling of the texture is wrong - each of the cobbles is enormous!
In 3dsmax, I would edit the UVW Map on the geometry.
What is the best procedure in UE4?

bleak copper Oct 11, 2016, 8:14 AM

#

I mean, you can have every PBR shader be an ubershader with dynamic nodes.

#

But that is inefficient for several reasons lol

#

Well, as long as it uses the same shading model.

fresh merlin Oct 11, 2016, 8:17 AM

#

(would I just but a 'master' TexCoord on all the various texture nodes?

bleak copper Oct 11, 2016, 8:21 AM

#

Sorry, thought you were responding to me. If the material seamlessly tiles, and your model doesn't have any weird UV mapping things, then you would need to modify the material to make it tile.

fresh merlin Oct 11, 2016, 8:22 AM

#

So a master texoord would be the way to go?

bleak copper Oct 11, 2016, 8:22 AM

#

I can't remember if I duplicated the material then made a static instance of that duplicate per tile or not...

#

It's actually been since 4.9 that I needed to do that specific thing.

#

Since then I've always used solid shading, or custom UVs in Blender... just happened to work out that way.

fresh merlin Oct 11, 2016, 8:25 AM

#

ok - thanks

bleak copper Oct 11, 2016, 8:28 AM

#

On the TexCoord nodes, click them, then adjust the UTiling and VTiling

#

Higher number means more tiles.

#

I should not be doing this at 4:30 am lol

fresh merlin Oct 11, 2016, 8:35 AM

#

haha

dense ravine Oct 11, 2016, 10:55 AM

#

Can someone tell me which one of them is more efficient? A and B are doing the same. Increasing NM strength.

📎 Normal_Strength_Performance.PNG

cloud cobalt Oct 11, 2016, 11:07 AM

#

B is what I would write in shader code

#

You should try both and see the instruction count in the stats pane

#

To be honest, you're never going to measure a real difference in actual use

#

Unreal does billions of operations at every frame, you can get pretty wild with materials before it goes out of hand

dense ravine Oct 11, 2016, 11:16 AM

#

i am encountering problems with the instruction count atm. values not displaying correctly. Need to close the window and reopen it again to get the real values >.< UE3.11 github version

cursive dirge Oct 11, 2016, 11:17 AM

#

that's some ancient UE alright

#

(sorry, had to)

dense ravine Oct 11, 2016, 11:18 AM

#

was meant to say 4.13 dunno why I worte 4.11 >.<

foggy valley Oct 11, 2016, 11:41 AM

#

both of those are one instruction count each I think

#

so incredibly negligible

#

it'll use code folding to reduce them to that single instruction

dense ravine Oct 11, 2016, 11:47 AM

#

thanks for the answers 😃

vale osprey Oct 11, 2016, 12:13 PM

#

@cloud cobalt you might go further than that, like single master material for all non-metals without masks or translucency

#

@dense ravine Append should be free, as it just constructs a vector or does swizzling operation

cursive dirge Oct 11, 2016, 12:16 PM

#

@dense ravine sorry, I just woke up when I wrote that (and you wrote you use 3.11)

cloud cobalt Oct 11, 2016, 12:18 PM

#

@vale osprey I did, actually. My game has around a dozen materials for the entire thing

#

Just pointing out the basic concept

vale osprey Oct 11, 2016, 12:20 PM

#

then apologies for pointing obvious 😃

cloud cobalt Oct 11, 2016, 12:22 PM

#

I think we've already talked about material instances extensively, back when we trolled about whether LOD materials should have options to automatically remove SSS, etc

#

😄

vale osprey Oct 11, 2016, 12:23 PM

#

yeeee, now I remember 😄

sleek leaf Oct 11, 2016, 12:30 PM

#

just noticed, was Translucency fixed in 4.13?

cloud cobalt Oct 11, 2016, 12:31 PM

#

What kind of fixing did it need ?

sleek leaf Oct 11, 2016, 12:31 PM

#

i could be mistaken, but in 4.12, it didnt render in the correct order

#

so translucent surfaces FAR BEHIND the closest one would get rendered first

#

just made a set of sliding doors and the rendering seems to be working as you'd expect 😄

dense ravine Oct 11, 2016, 12:33 PM

#

An other question^^
Which one of them is more efficient. B is saving on texture samplers but is there a cost to using the same texture several times with different UV scales?

📎 TextureReuseUVScale.PNG

sleek leaf Oct 11, 2016, 12:34 PM

#

B

#

takes up less room in memory

dense ravine Oct 11, 2016, 12:36 PM

#

yeah that is what I figured but I am more interested in some possible costs that maybe arent obvious

cloud cobalt Oct 11, 2016, 12:36 PM

#

Like I said earlier, simple materials like that are never going to be really expensive

#

You should go for the easiest workflow rather than trying to optimize it

#

I mean, the most minute lighting change will have more impact on performance than this

#

(Still happy to answer, just saying, don't focus too much on it)

dense ravine Oct 11, 2016, 12:52 PM

#

thank you. Was checking some materials and looking for optimizations. So will just pack the mask textures into one and call it a day since there is nothing else to do.

cloud cobalt Oct 11, 2016, 12:59 PM

#

Did you try the gpu profiler,?

#

It gives great insights into what is actually slow in your scene

#

Run your game in the editor and type "profilegpu" in the console

#

I was super surprised by the results, like SSR and AA costing 2-3ms each

dense ravine Oct 11, 2016, 1:01 PM

#

its all turned off already^^ most of the game is running smoothly at 60 fps on console have just some places still causing troubles

vale osprey Oct 11, 2016, 1:02 PM

#

@dense ravine one texture sample takes something similar to 16 instructions, so if you can pack as much as possible into a single texture the better. Even better is to calculate what you read from texture when possible

#

so A and B will be more or less equal in performance

#

it's still 3 samplers and that matters more than what ever you sample 4 channels or 3 channels

dense ravine Oct 11, 2016, 1:06 PM

#

so reusing the same texture still adds to texture sampler count?

vale osprey Oct 11, 2016, 1:06 PM

#

you still read 3 textures in B right?

dense ravine Oct 11, 2016, 1:07 PM

#

because in B its the same texture but i use different scaling and the according R,G,B channels only. Sorry that wasnt explained properly

vale osprey Oct 11, 2016, 1:07 PM

#

so B is the same texture sampled 3 times?

dense ravine Oct 11, 2016, 1:08 PM

#

yes i think so, but i dont know what counts as sampled or not^^

vale osprey Oct 11, 2016, 1:08 PM

#

it will be faster than sampling 3 other textures, but it still very slow operation comparing to doing math

dense ravine Oct 11, 2016, 1:09 PM

#

I see

vale osprey Oct 11, 2016, 1:09 PM

#

but it will be faster only if you sampling is cache coherent

#

like all 3 samples taken from 32x32 square of texels

#

not from opposite parts of the texture

#

@dense ravine by "sampled" I mean shader instruction which reads from texture

dense ravine Oct 11, 2016, 1:11 PM

#

is UV scaling happening before or after sampling? From my naive understanding i think its before

#

so if I use the same texture with 3 different UV scales, are they cache coherent or not?

vale osprey Oct 11, 2016, 1:15 PM

#

it's happening before, they will be cache coherent only if texels that you sample are close to each other

#

even that doesn't guarantee it 😄

dense ravine Oct 11, 2016, 1:17 PM

#

thanks, so the only real saving you get is the reduced memory footprint by packing. You can't really count on the other things being faster?

plush yew Oct 11, 2016, 1:29 PM

#

This might be a dumb question, but is there a way to get textures back out of Unreal? e.g. you lose the original PNG and want to export a texture asset to get the PNG.
I've tried exporting, but it seems to give me an alpha-less TGA, which isn't much use.

dense ravine Oct 11, 2016, 1:36 PM

#

works here, just tested

#

UE4.13.1

#

@plush yew

vale osprey Oct 11, 2016, 1:44 PM

#

@dense ravine well even that is questionable, there are different storage formats. Like only 3 channel or 4 channels, or 3 channels + alpha, or normal map

#

UE4 uses BC5 format for normal maps, for the rest I don't know

dense ravine Oct 11, 2016, 1:45 PM

#

maybe it converted the transparency to an alpha channel? have you checked it @plush yew

vale osprey Oct 11, 2016, 1:46 PM

#

but if you have 1 texture for alpha or metallness it obviously makes sense to pack it into 4 channel texture

plush yew Oct 11, 2016, 1:46 PM

#

Whoops, OK I checked with Pupp. Alpha is exported correctly, it's just Photoshop is stupid when reading TGAs

#

Yeah it's a 4-channel texture, it was a UI texture

dense ravine Oct 11, 2016, 1:48 PM

#

is there a difference between 4 channels and 3 channels+alpha in ue4. I know that 3 channels + alpha is the same size as two 3channel textures of the same size.

#

@vale osprey

vale osprey Oct 11, 2016, 1:55 PM

depends on used format, some of them have compression

but these are not all, I don't see BC5

vale osprey Oct 11, 2016, 2:32 PM

#

found it, it's in a separate category, compressed surfaces
https://msdn.microsoft.com/en-us/library/windows/desktop/hh308955(v=vs.85).aspx

#

anyway, this is just for reference, I don't know which of them UE4 uses besides BC5 for normal maps

dense ravine Oct 11, 2016, 2:38 PM

#

will check them out👍

plush yew Oct 11, 2016, 3:05 PM

#

@dense ravine That's surprising to me, is there a way I can tell which of those two my texture is? 4-channel vs 3-ch+A ?

dense ravine Oct 11, 2016, 3:07 PM

#

Ahh, sorry for the confusion. I was talking about 3 channel vs 4 channel texture.

#

But you should be able to test it yourself inside of unreal since the size is dispayed besides the used compression in UE @plush yew

did someone already try 4.14 preview (promoted branch)?

kindred viper Oct 11, 2016, 3:31 PM

#

a few people have I guess. I hear better things than 4.13 so i'm optimistic 😃

patent ibex Oct 11, 2016, 3:34 PM

#

for some reason it keep crashing for me (and whole team) when i try to load map. fatal crash with no information at all
log's call stack blames MapBuildDataRegistry asset i suppose

anybody got the same problem with their maps?

cursive dirge Oct 11, 2016, 3:55 PM

#

I've tried 4.14 promoted on 3 different builds

#

no map loading issues

#

but then again, it's not mean to be stable

#

so things could just break on individual builds

#

kinda curious though when they'll branch of the 4.14

#

would see what feats get locked there

craggy nymph Oct 11, 2016, 4:21 PM

#

I'm working in BP and I've set a break point. When I play and hit the breakpoint, the game pauses. I would like to check the world outliner and see if certain actors are attached to another actor, or not. How can I check that? The outliner is greyed out and paused as well. Anybody got an idea?

are you creating multiple spline instances rather than using a single spline?

#

@keen pine

keen pine Oct 11, 2016, 6:55 PM

#

I was under the impression that it was all one spline, i just started clicking with ctrl + left mouse

vale osprey Oct 11, 2016, 6:55 PM

#

Or your texture has something on edges

#

(Checking on the phone)

keen pine Oct 11, 2016, 6:56 PM

#

hmm

#

Im having a real arse ache with these splines

#

they go crazy

kindred viper Oct 11, 2016, 6:56 PM

#

it looks like the two spline points in the foreground are showing it as two splines

keen pine Oct 11, 2016, 6:57 PM

#

do you name sockets in spline segments ?

kindred viper Oct 11, 2016, 6:57 PM

ive never done that

I get a lot of issues like this

kindred viper Oct 11, 2016, 6:59 PM

#

See landscape splines are slightly different than what I use. I build with regular splines and apply them to the landscape later. Just because I learned to do that before I learned landscape's had splines :p

keen pine Oct 11, 2016, 6:59 PM

#

there is a better way to use splines to make roads?

kindred viper Oct 11, 2016, 7:00 PM

#

I really cant say about landscape splines for sure. I have had no real issues with regular splines for roads though.

keen pine Oct 11, 2016, 7:01 PM

#

May, I ask one more question mate and thank you for the help, where do you find splines to do that since i've got no experience

#

ah wait, actors

kindred viper Oct 11, 2016, 7:02 PM

#

its an actor component

keen pine Oct 11, 2016, 7:02 PM

#

i see it now, thanks

kindred viper Oct 11, 2016, 7:02 PM

#

there is a function for apply spline to landscape that you can use. It essentially digs itself into the landscape as you would expect.

keen pine Oct 11, 2016, 7:03 PM

#

any special manner to connect them to each other ?

kindred viper Oct 11, 2016, 7:04 PM

#

Well with multiple splines you wouldn't connect them. You would either use a single spline and adjust the spline meshes along the way to suit, or if you did have multiple, you would just get the world location of the last spline point and set the new spline's location to that one. Maybe a slight adjust if the mesh overlap causes any z-fighting

keen pine Oct 11, 2016, 7:05 PM

#

I see it now, thanks, I'll try and learn it fast so thank you

kindred viper Oct 11, 2016, 7:05 PM

#

I can highly recommend the tutorial that zak parrish did on the UE Road Tool. It got me off to a flying start and I even got it done in C++ from that video when I had no c++ experience

#

thanks man

keen pine Oct 11, 2016, 7:40 PM

#

@kindred viper do you have any idea why the spline ends up going like this?

#

http://i.imgur.com/RPLvFm4.png

#

doesnt matter, it's local/world rotation setting

vale osprey Oct 11, 2016, 7:51 PM

#

You've rotated node

vale osprey Oct 11, 2016, 8:22 PM

#

I had bug like this but it was rotating 90 degrees and I couldn't rotate it back. Had to redo it, this is since 4.12

#

So unless you've rotated it yourself you might have caught it

keen pine Oct 11, 2016, 8:32 PM

#

I just did height blending manually when I was still working on this jam

#

basically I had to as I wanted to use splatmap driven from materials instead of the built-in layering system

#

I could have just imported the masks for layers though but would have lost some of the control there

#

also

#

to the spline thing

#

landscape splines tend to deform way better than spline meshes

#

also, Zak totally redid just this tutorial https://www.youtube.com/playlist?list=PLHadbgEqCTxDgj-RwPQGkaUypb05NJYN6 with small additions like banking etc

Should an unwrap UV modifier be created for every single piece of 3dsmax geometry, even for objects that will only have 'colour' materials on them (i.e. no bitmaps), or do I just need to create this map channel if I want to apply textures?

#

anyone know if there is a console command that does what eject does in the editor?

foggy valley Oct 12, 2016, 10:25 PM

#

you'd have to make a custom pawn for that I suspect

#

shouldn't be hard though

#

I doubt a console command exists, it'd be too easy to use it to cheat

#

@fresh merlin: if you're doing flat colour you can ignore the UVs - UNLESS you want them to receive static lighting. In which case you need to unwrap just to get the polygons in the index.

#

good unwrapping always pays off down the road

upper heart Oct 12, 2016, 10:29 PM

#

aren't console commands blocked in real games anyways?

#

I mean there are a lot of them that would make cheating easy

foggy valley Oct 12, 2016, 10:29 PM

#

not sure

vale osprey Oct 12, 2016, 10:54 PM

#

@upper heart console works in non shipping builds if you need this for test

#

Maybe even for shipping you can enable it with a set of allowed command

#

Did you find "eject" in console?

upper heart Oct 12, 2016, 10:57 PM

#

yeah that's what I figured

#

@vale osprey no I can't find an eject in the console

#

or anything like it

vale osprey Oct 12, 2016, 10:57 PM

#

probably just an editor thing

#

you can make pawn like that as antidamage suggested

#

I think default pawn can just fly around

Anyone here got experience with morph targets and transforms?

#

I'm trying to figure out a way to transfer morph targets off my character and onto a shirt.

#

without an artist revolt

cursive dirge Oct 15, 2016, 1:03 PM

#

@timber relic you might want to tell what modeling too you are using as well

#

I dunno if there's any direct transfer thing for such case, shirts shape doesn't even match bodys shape 1:1

#

but for example, in Modo, you could probably first store initial morph position for shirt, then use background constraints on body and adjust the morph value on body to max, turn off background constraint, fix the issues on shirt and then store the new morph value on shirts max, repeat for other morphs if there are any

#

the logic there is that background constraint would force the shirt to grow size too as background (body) kept pushing the shirt outwards while it grew in size

timber relic Oct 15, 2016, 1:16 PM

#

Modo. Hm.

#

Hey! @cursive dirge Good to see you!

#

Modo is a thought. A painful one, but a thought.

cursive dirge Oct 15, 2016, 1:16 PM

#

well

#

if you use zbrush

#

you could just use lower subdivision level there and it's projection tool

#

with the same idea I just described

#

zbrush has layer system that allows you to store morphs

timber relic Oct 15, 2016, 1:17 PM

#

We have max, maya, c4d, zbrush, substance... had not tried mod yet

#

Hmmm

cursive dirge Oct 15, 2016, 1:17 PM

#

but for that to work properly, you'd need to have lower level subdivision mesh of the same mesh there

#

as if you project higher poly, it tends to just snap the verts to the body verts

timber relic Oct 15, 2016, 1:18 PM

#

I was actually wondering about transform(bone) or other variants for simpler objects. Like... okay, I'm working with superheroes, right?

Now, superheros wear the fancy gloves with cuffs and bat-spikes and that stuff.

cursive dirge Oct 15, 2016, 1:18 PM

#

anyway, I'm not any expert on modeling tools though, it's possible that there's some better way of solving that

#

that's just the only thing I could initially think of

timber relic Oct 15, 2016, 1:19 PM

#

Most of the glove, I can just do with texture, then stick the spikes on the side - the trick is, a morph target may make the arm bulkier. I'm trying to find some way to increase the diameter of a band or the distance from center of a attached mesh.

#

nods.

#

It doesn't have to track one-to-one, just close to it, if that makes sense - I haven't messed with transforms much but I was thinking about dynamic scaling as being an option

I think usually people would just skin the cloths with the char and that would solve the problem automatically

Swappable clothes

cursive dirge Oct 15, 2016, 1:22 PM

#

unless you need to do like ton of them, but if you look at games that do that, most of the outfits are usually some sort of hardsurface armors that don't need to use any skinning

timber relic Oct 15, 2016, 1:23 PM

#

Superheroes. Pain in the neckl.

#

Hm. Good thing is Modo is british. Price keeps going down

cursive dirge Oct 15, 2016, 1:24 PM

#

well, you can do similar things surely on max too

#

if it doesn't have constraint thing built in, I'm pretty sure there's some 3rd party script for it

#

also

#

it's more like "wrap this mesh on top of other mesh" kinda thing, so it'll not give you perfect results

#

zbrush'es projection tool can do similar things, it just does it in single step so you might need to do few steps for each morph value to make it deform nicely

#

but now that I think about it

#

artist would probably just fix the cloth morphs manually :p

#

like use inflate, move etc brushes on zbrush to make the cloth match body shape on different morphs

#

shouldn't take that long and will give better results

timber relic Oct 15, 2016, 1:28 PM

#

Yeah, artist is saying 'no, 10 morph targets are too many, find a way to automate'. He's got a point.

cursive dirge Oct 15, 2016, 1:28 PM

#

heh

#

does there even need to be mesh inside the cloth? is the cloth transparent/masked so you can see the arms etc under cloth?

#

it seems like lots of work for something that doesn't even need to happen

#

like if you want to morph the hand, but underneath the cloth, why?

#

oh right, it's probably more about using the body to make the morph and then plan is to just mirror it into all cloths?

#

you'd think someone would have created some scripts for that

timber relic Oct 15, 2016, 1:32 PM

#

eah

#

Yeah

#

Surprisingly, can't find a darn thing that isn't a corporate proprietary tool that is rumored but not done.

#

Tried Creative Crash... not sure where to look.

#

#

Nothin

feral dirge Oct 15, 2016, 1:37 PM

#

I wake up to read "Modo is a painful thought" - God damn it man, MODO is THR BEST thought

#

Modo is love, Modo is life

#

Also to the guy bitching about 10 morphs targets for the cloth...

#

Batman arkham asylum had approx 100 bones in the cape with 700 animations

#

So you can tell him from me that it's more than doable :P

#

Also have you looked at marvellous designer? It's marvellous for clothing

#

For game reference MGSV is the most recent one of note to use it

timber relic Oct 15, 2016, 1:42 PM

#

It is. There's some weird stuff with the licensing and textures - apparently you can't repoly the mesh and use it.

feral dirge Oct 15, 2016, 1:42 PM

#

You can just import your own mesh

#

Easy as Pi

timber relic Oct 15, 2016, 1:43 PM

#

Yes, but then you can't use the generated textures according to their license.

#

Makes no sense to me.

feral dirge Oct 15, 2016, 1:43 PM

#

That is strange but wouldn't be hard to work around surely

timber relic Oct 15, 2016, 1:54 PM

#

Modo is a painful thought just because 'aw damn it another piece of software'

#

And 'moneys'

#

It is, however, something I had heard good things about. Modo can do this, you think?

#

Does Modo call it morph targets or blendspaces?

How fast is Blueprint compared to c++?

cursive dirge Oct 15, 2016, 9:18 PM

"depends"

#

also, speed is irrelevant for most gameplay code

#

unless you do something silly and do all the work on ticks

#

but you shouldn't do that on c++ either unless it's a thing that has to be done on tick

rapid pawn Oct 15, 2016, 9:27 PM

#

I did something similar to test this: a ineffective bullet drop mechanic on tick

#

after some "shots" on blueprints: stuttering
in c++ though: stuttering(bad cpu) but less

#

I also try to avoid using tick

@rapid pawn so far I haven't see more than 2-3 performance boost from@moving code to c++

Will I have to take into consideration the angle of the camera when I use DeprojectMousePositionToWorld()

#

Just that it seems to be slightly off on the yaw when aimed towards a southern angle, since the camera is slightly back, raised high and angled towards the players I though that maybe the mouse position/direction would translate a little off

I wanted to check before I do something stupid, when I load a new level, gameMode remains as it was, right?

#

I mean, it's not destroyed and recreated?

static coyote Oct 18, 2016, 5:56 PM

#

I'm hardly an expert, but afaik Game Mode and Game State are the same in that they both exist only on the server, and therefore should be persistant while the program is running.

there is a comment saying
" * A GameMode actor is instantiated when the level is initialized for gameplay in

C++ UGameEngine::LoadMap(). "

#

that made me wonder

static coyote Oct 18, 2016, 5:59 PM

#

Can you link that documentation?

plush yew Oct 18, 2016, 6:04 PM

#

its on gamemode.h

static coyote Oct 18, 2016, 6:04 PM

#

Oh I see, an actual code comment.

#

Anyway, I'm mostly certain that it persists. Based on the wording of that comment, I would say that it is instantiated the first time LoadMap() is called, and whenever that function is called again the new instance deletes itself (singleton pattern). I haven't actually looked at it though, so this is conjecture based on a common programming pettern.

plush yew Oct 18, 2016, 6:13 PM

#

sorry it isnt persistent

#

it is created anew every time a new map is created

static coyote Oct 18, 2016, 6:16 PM

#

Really? That's interesting. I suppose logically that does make sense, the game state is changing when the level is changing. Maybe what you're trying to have persist doesn't actually belong in game state?

knotty brook Oct 18, 2016, 6:33 PM

GameInstance is persistance GameMode is not

if you want something to cross levels or from menu to levels, etc, use a GameInstance

How can you prevent Unreal from putting Data on your C Drive if you installed it on another drive? Wanted to package a project and UE4 just busted my SSDs Capacity with its "DerivedDataCache" Folder

#

And no I don't want to use my 128GB SSD for that....

#

And can I delete this "DerivedDataCache" without worries?

sand escarp Oct 18, 2016, 8:42 PM

#

@plush yew in BaseEngine.ini you need to change the Paths in [DerivedDataBackendGraph] and [InstalledDerivedDataBackendGraph]

#

deleting the folder is abolutely save, once you fire up the engine again they will be regenerated though

plush yew Oct 18, 2016, 8:45 PM

#

But if I do this correct then UE4 should put it back into my SSD, right?

sand escarp Oct 18, 2016, 8:46 PM

#

if you change the variables in BaseEngine first it will be generated in the new directory, yes

#

and you can then get rid of the folder on C:

plush yew Oct 18, 2016, 8:47 PM

#

There are also other folders like "4.10" to "4.14" can I delete them as well?

sand escarp Oct 18, 2016, 8:49 PM

those would be the derived data caches for these engine versions. the change I suggested is per engine version (and it will be ovveridden by any engine update btw)

Nobody is familiar with my issue mentioned above? Custom functions in packaging can't be cooked because "some" package" is missing.

So first question, is cloning a ue fork off github acceptable or should I use strictly perforce mercurial?

#

I want to save all my assets also

#

Like the project files for art and models

#

Unless I can use a gimp project file directly in UE material, would need to access each channel, last save is what would update in UE
