.....

dusty gyro May 17, 2018, 11:23 AM

#

have you tried to reset xform ?

#

I've just done it on a mesh

#

and it now imports as a static mesh actor instead of actor

#

yep this is it

normal river May 17, 2018, 11:24 AM

#

No. But I reset, will I lost the map channel?

dusty gyro May 17, 2018, 11:25 AM

#

no non no

normal river May 17, 2018, 11:25 AM

#

No?!!!

#

Ok

dusty gyro May 17, 2018, 11:25 AM

#

you won't lose it

normal river May 17, 2018, 11:25 AM

#

Lets try

dusty gyro May 17, 2018, 11:25 AM

#

save a backup just in case

#

of your max file

#

reset xform tends to do weird stuff

normal river May 17, 2018, 11:25 AM

#

(If you fix my scene I will buy you a house or something like that xD)

dusty gyro May 17, 2018, 11:26 AM

#

rofl, just a thanks is enough 😉

normal river May 17, 2018, 11:26 AM

#

xD

#

.....LOADING

#

UUUUMMMMMMMM.....Almost. Now I have another problem xD

#

Look

#

📎 3.jpg

#

The mesh has darkened and looks transparent in some areas

dusty gyro May 17, 2018, 11:33 AM

#

looks like flipped faces

normal river May 17, 2018, 11:33 AM

#

But you fixed the first problem

#

Yes

dusty gyro May 17, 2018, 11:34 AM

#

are your polys facing the right direction in max ?

#

reset xform shouldn't do that

#

at worst its gonna change the pivot or transform

#

but not flip faces like this

#

and the mesh being dark/shadowed differently is probably due to the flipped faces

normal river May 17, 2018, 11:36 AM

#

....Let me check the direction poly

#

Fuck! You are rigth O_O

#

I have invert polys

dusty gyro May 17, 2018, 11:37 AM

#

hehe

#

xform can do weird stuff

#

but when it does, then something isn't right with the mesh in first place

normal river May 17, 2018, 11:38 AM

#

uumm

#

Maybe

#

Im goona try to fix this new problem

#

firist of all, Im goona try to fix one or two object.

#

I will write in a few minutes. Thanks a lot!

dusty gyro May 17, 2018, 11:40 AM

#

no problem, happy to help 😃

#

there's so few studio users in here

glossy creek May 17, 2018, 2:57 PM

#

I have a nice Unreal walk through scene and a idle Oculus Rift ready in my office. Client is visiting tomorrow, and I want to show a quick implementation of VR in the scene. What is the quickest way to get VR headset working in an unreal scene. Interactivity is not important. Thanks!

dusty gyro May 17, 2018, 2:59 PM

#

@glossy creek have you looked at the unreal studio product viewer template ?

#

you'll have both 2D and VR in one package

glossy creek May 17, 2018, 3:01 PM

#

Yes, but its a lot to dig through to just figure out the relevant part that I need. This client visit is a surprise, because I am taking a step one through one hundred approach to learning blueprints.

#

Oh wait, I have not LifeForLife, I was thinking about the VR template.

dusty gyro May 17, 2018, 3:01 PM

#

hehe

#

the Vr template is a bit bare bones

#

and it requires navmeshes

#

the studio one though doesn't

glossy creek May 17, 2018, 3:02 PM

#

Bare bones is fine, and navigation can be left out for now. Just need to "copy and paste" the relevant blue print classes I would assume.

dusty gyro May 17, 2018, 3:03 PM

#

I'm not even touching the blueprints when its just to view stuff

paper night May 17, 2018, 3:03 PM

#

Hi there! I have a quick question for you guys.

dusty gyro May 17, 2018, 3:03 PM

#

I remove a few actors from the template scene, then add a sublevel with the things I want to show

#

move a bit the player spawn and bam it works

paper night May 17, 2018, 3:03 PM

#

I'm working on the lighting for a scene in UE4 and i'm getting weird shadows whenver I bake the lighting.

Any clues?

dark oriole May 17, 2018, 3:04 PM

Lightmap resolution not high enough.

dusty gyro May 17, 2018, 3:04 PM

#

low resolution lightmap

paper night May 17, 2018, 3:04 PM

#

Aight. How can I raise that?

dusty gyro May 17, 2018, 3:04 PM

#

Okay. Thanks!

dusty gyro May 17, 2018, 3:04 PM

Cool, I

I'll try and grab the settings* from that and paste them into my Unreal Studio Project.

dusty gyro May 17, 2018, 3:10 PM

@paper night found the settings ?

paper night May 17, 2018, 3:11 PM

Yep I have!

#

Problem solved, muchachos.

📎 unknown.png

#

Here's another question though: see that thin line in the shadow of the pillar? That horizontal thin line?

#

Thing is, it's not in my mesh.

#

See? The thin line doesn't make sense. Any suggestions?

📎 unknown.png

dusty gyro May 17, 2018, 3:13 PM

#

your UV is probably the problem

#

oh wait

#

the line on the ground

paper night May 17, 2018, 3:13 PM

#

Yep!

dusty gyro May 17, 2018, 3:13 PM

#

are you sure your mesh has all its vertices welded ?

paper night May 17, 2018, 3:13 PM

#

Nope. I'll ask the 3D artists.

#

Is there any way to check that inside UE4?

dusty gyro May 17, 2018, 3:14 PM

#

it looks like there's another plane on top of the floor

paper night May 17, 2018, 3:14 PM

#

OH SHIT you're right. There IS a plane on top of the floor.

#

My bad.

dusty gyro May 17, 2018, 3:14 PM

#

:p

paper night May 17, 2018, 3:15 PM

disable its shadow casting. Thing's looking pretty now.

#

Thanks a bunch for your help!

dusty gyro May 17, 2018, 3:15 PM

glossy creek May 17, 2018, 3:15 PM

#

I have a shadows question. Despite having high resolution LightMaps, I will still often get shadows that I consider blochy, what else can be done outside of LM res?

paper night May 17, 2018, 3:16 PM

#

UVs?

#

Your mesh might need a new Lightmap UV set

dusty gyro May 17, 2018, 3:16 PM

#

can you show us your lightmap UVs @glossy creek ?

paper night May 17, 2018, 3:16 PM

#

chances are your lightmap UVs are messed up, resulting in low res for the segment of the mesh you're looking at

glossy creek May 17, 2018, 3:17 PM

#

Not at the moment, working on something else to get out the door. I can tell you its a wall, and I flattened the UVW's in max, simple wall, verts sealed, no missing faces, etc.

#

Shadows not terrible, just not on the level of vray or some of the top level Unreal ArchViz examples, like nutsnuts

dusty gyro May 17, 2018, 3:23 PM

#

@glossy creek What are your settings for lightmass ?

#

the defaults are pretty crappy for archviz

glossy creek May 17, 2018, 3:24 PM

#

They are messed up now, because I've been messing with the GPU lightmass beta thing. I did production and 10+ bounces, etc.

#

Pretty darn high, I had swarm agent pounding 10 or so machine slaves.

dusty gyro May 17, 2018, 3:24 PM

#

yeowch xD

#

https://gfycat.com/DiscreteScientificKouprey

Gfycat

#

One skylight with HDRI, 10 bounces, quality at 6 and smoothness at 0.8

#

Using Production quality and GPU lightmass

#

one machine to render, (GTX1080 oc), does it in a couple minutes

glossy creek May 17, 2018, 3:26 PM

#

Yeah, I have a GTX1080 at home, and a older Titan Black here at work. Works wonders.

dusty gyro May 17, 2018, 3:26 PM

#

oh and scale at 0.1

#

do you have a sample of your bad looking results ?

glossy creek May 17, 2018, 3:27 PM

#

ill load up

#

📎 unknown.png

dusty gyro May 17, 2018, 3:30 PM

#

Right

#

this may be caused by the GPU lightmass

#

other users had the spotchyness I think

glossy creek May 17, 2018, 3:31 PM

#

That was baked before that I belive

dusty gyro May 17, 2018, 3:31 PM

#

oh really ?

#

what is your resolution scale ?

#

should be the first lightmass parameter

#

"Static Lighting Level Scale"

#

I usually put it at 0.1 or lower

glossy creek May 17, 2018, 3:33 PM

#

Yeah, I'm aware of it, just loading the scene now

dusty gyro May 17, 2018, 3:33 PM

#

you can also try to switch off the lightmap compression

#

it'll take more VRAM, but can improve the looks

glossy creek May 17, 2018, 3:34 PM

#

I've messed with low settings on it, and at times had huge diminishing returns.

#

"low" as in .2,.3 etc

#

Okay, it is set to .35
Not 100% sure that is what I had it to when I did the bake above.

dusty gyro May 17, 2018, 3:35 PM

#

have you tried to bake the scene with the GPU lightmass ?

#

maybe it'll give better results with less noise, who knows

#

you're bound to have a little noise anyways

glossy creek May 17, 2018, 3:36 PM

#

I have, it was faster, but still shadows were not sharp

#

4096 is my lightmap res!!!

dusty gyro May 17, 2018, 3:36 PM

#

woh that's way too high

glossy creek May 17, 2018, 3:36 PM

#

Yeah. I went for broke

dusty gyro May 17, 2018, 3:36 PM

#

2048 should be the maximum

#

and in rare cases

#

maybe you should split the wall ?

glossy creek May 17, 2018, 3:36 PM

#

The GPU render HATES very high lighmap settings, found that out the hardway

dusty gyro May 17, 2018, 3:37 PM

#

yep, it clogs the GPU vram

#

unless you have a quadro with a lot of it you are bound to crash :p

glossy creek May 17, 2018, 3:38 PM

#

The problem I found with splitting the walls, is that it introduces problems where the walls meet, not to mention the shadows were still blochy, I have gone that route in test.

dusty gyro May 17, 2018, 3:38 PM

#

GPU lightmass should fix the first problem

#

what is your Indirect quality value ?

glossy creek May 17, 2018, 3:39 PM

#

📎 unknown.png

dusty gyro May 17, 2018, 3:39 PM

#

holy fuck

#

no wonder you have bad shadows

#

xD

glossy creek May 17, 2018, 3:39 PM

#

LOL

#

Bad unwrap?

dusty gyro May 17, 2018, 3:39 PM

#

you bet

#

there's way too much stuff in that UV

#

try to cut it into pieces

#

lots of assets with lower resolution is better than a massive one

glossy creek May 17, 2018, 3:40 PM

#

Okay, I'll have to re-approach from the start, with all that I have learned. I have done test where my walls where not attached, but I should go back and try that test again but do it better.

dusty gyro May 17, 2018, 3:41 PM

#

see for instance

#

the scene I posted earlier

#

with the flat colors

#

every cube is its own mesh

#

every wall side too

#

this is a bit overkill, but you get very clean light bakes that way

#

and for walls I'm not going higher than 1024

#

floors and ceilings, 2048

#

📎 HighresScreenshot00003.png

glossy creek May 17, 2018, 3:43 PM

#

I was under the assumption, referencing that scene animation above you posted, that walls should have all faces, to avoid light bleed.

dusty gyro May 17, 2018, 3:43 PM

#

And its well enough to get good looking results

#

well there's an external wall

#

I'm just hiding it to show the inside :p

glossy creek May 17, 2018, 3:44 PM

#

Oh okay

dusty gyro May 17, 2018, 3:44 PM

#

📎 HighresScreenshot00004.png

#

Looks like this from outside

glossy creek May 17, 2018, 3:44 PM

#

Yeah, nice results.

dusty gyro May 17, 2018, 3:45 PM

#

this is a one hour hackjob I made a few weeks ago

#

to test out GPU lightmass and lighting scenarios

#

when I told you about super simple UVs

#

https://i.imgur.com/3RLT1f1.jpg

Imgur

#

😂

#

even with 2048px max for lightmap resolution, my screen is bright red while in lightmap res debug

glossy creek May 17, 2018, 3:47 PM

#

Yeah, I need to pair back down to test scenes to work out these issues.

#

What I dont like about unreal lightmass, is that sometimes to reduce noise, it seems like adding light, is the nudged solution. For instance, the provided realistic lighting example scene of an apartment, looks nice and clean, take away a few lights, and the noise starts to show up.

dusty gyro May 17, 2018, 3:49 PM

#

well lightmass is a pretty old piece of kit

#

epic really needs to bump up the algorithms used

glossy creek May 17, 2018, 3:50 PM

#

Yeah, I'm grinding my teeth coming from Vray.

dusty gyro May 17, 2018, 3:50 PM

#

at least now it takes skylight bounces in account, you were limited to one bounce before

#

but you can't do realtime with Vray !

glossy creek May 17, 2018, 3:51 PM

#

No, exactly, everything is a trade off.

dusty gyro May 17, 2018, 3:51 PM

#

with how much epic is investing into studio

#

I'd be surprised if they don't look at better light baking stuff in the next year or two

glossy creek May 17, 2018, 3:53 PM

#

I have full confidence in Epic going into this direction, as well as plug-in support making it better. So much so I've really pushed our company to embrace Unreal, VR, and spend time on it. I'll be going down to reighley north carolina for their epic studio learning thing next month, so - I'm all in!

dusty gyro May 17, 2018, 3:56 PM

#

oh you're attending the studio formation, nice !

glossy creek May 17, 2018, 3:56 PM

#

"Unreal Academy"

dusty gyro May 17, 2018, 3:56 PM

#

I wish I could go, but a trip from France to the US is a bit difficult to justify 😅

#

yeah

#

I'm pretty hyped about the new datasmith features in UE4.20 aswell as the Revit compatibility they just started working on

glossy creek May 17, 2018, 3:57 PM

#

Datasmith is making this whole thing possible, or else I wouldn't have bothered.

dusty gyro May 17, 2018, 3:57 PM

#

yeah

#

I've been trying to import CAD stuff before datasmith

#

it was a horrible process, very time consuming and not giving really good results

#

plus performance for VR was horribad

#

with DS and python scripting, we were able to make a few tools to optimize everything in a few clicks

#

anyways, been greating talking to you, gotta bounce home !

#

I'm always lurking in this channel, so if you have any questions don't hesitate to ask 😃

glossy creek May 17, 2018, 3:59 PM

where is the problem?

paper night May 17, 2018, 5:52 PM

#

Yo, another question for you lot: why isn't Screen Space Reflection working for me?

#

The floor has high specularity and low roughness, it works fine with a reflection cube

#

but my SSR wont work.

dusty gyro May 18, 2018, 7:18 AM

#

@paper night using forward or deferred renderer ?

paper night May 18, 2018, 3:08 PM

#

Deferred

#

i got it to work but now its looking kinda odd

#

Sometimes it looks just right

📎 unknown.png

#

However, sometimes it gets a bit weird.

📎 unknown.png

#

then it just gives up.

📎 unknown.png

#

what gives?

royal osprey May 18, 2018, 3:22 PM

#

those are screen space reflections failing

#

and yeah it does that..

#

what you can do is add a reflection plane

#

much more stable reflections with it.

paper night May 18, 2018, 3:23 PM

#

Oh that did the trick!

#

Thanks a bunch, pal.

royal osprey May 18, 2018, 3:25 PM

#

up the "screen percentage" to get nicer reflections even

#

on the planar reflection

paper night May 18, 2018, 3:29 PM

#

Now, planar's doing the job just fine, however it's not reflecting my atmospheric fog properly!

📎 unknown.png

solemn hawk May 18, 2018, 3:32 PM

#

I believe the reflection planes don't reflect post process effects like fog? Not certain though

royal osprey May 18, 2018, 3:32 PM

#

hmm you could fake it by adding a sky or a large plane behind it

#

it's plain white anyway so I dunoo if your fog is really doig you any favors

solemn hawk May 18, 2018, 3:33 PM

#

I would put a sphere with an hdri outside, that will allow your skylight to get better lighting from its capture

paper night May 18, 2018, 3:39 PM

#

I have added a Sky Light and that did the trick!

solemn hawk May 18, 2018, 3:42 PM

#

make it stationary, that'll give the best result

pale prairie May 18, 2018, 4:31 PM

#

You really want to stay away from SSR for arch viz

#

There is a great evermotion tutorial on how to get good, clean, reflections in ue4 just google it

#

On a different note you probably want to stay away from super shiny reflective materials because they generally look artificial and are rarely seen irl

#

Your reflections should be subtle not blatant

gentle osprey May 20, 2018, 7:50 PM

#

Out of curiousity, is there a preference between bringing in lights from our original source (ie: revit - 3ds lights) or just using UE4 lights?

solemn hawk May 21, 2018, 6:26 AM

#

not really, depends on what you want to do. right now the auto exposure doesn’t work with correct camera exposures so the physically based lighting units are mostly useless for now

royal osprey May 21, 2018, 7:48 AM

#

it saves you from having to position them, that's about it

dusty gyro May 21, 2018, 9:24 AM

#

unless your project already has lights in the max file, doesn't serve any purpose

gentle osprey May 21, 2018, 1:54 PM

Do I have to have the debug part of the code?

royal osprey May 22, 2018, 11:27 AM

I had something like that happen to me, but only parts of my scene were black. Added a spherical reflection that covered the whole scene and it got rid of the black parts of my map, Unreal can be really strange like that.

But I had one of this big balls, and the result was the same. T_t But I will try again

dusty gyro May 22, 2018, 2:26 PM

@gentle osprey what is your glass material like ?

#

also, sometimes you need to use cube reflections instead of sphere to get more accurate results

#

transparent material master: https://i.imgur.com/DRMn1xp.png

#

even with a box reflection and the center being outside, it pulls the reflections from inside the space

dusty gyro May 22, 2018, 2:55 PM

#

hah, its the material from that tutorial !

#

I've found out that lowered refraction values work better

#

as for reflections, you'll have to align and scale the boxes/spheres correctly, it takes a bit of tinkering but you'll get the results you want @gentle osprey

gentle osprey May 22, 2018, 3:26 PM

#

I think the only lower increment I can go on refraction is 0 for this instance but I may have to

pale prairie May 22, 2018, 3:41 PM

#

@normal river use alt + 0 to check lightmap density

#

also if your UV maps are bugged it can give really wierd effects including black

normal river May 22, 2018, 3:53 PM

#

@pale prairie How can I Know it my UV Maps dosent work? Because, at the end of a render, I dont have any warning or mistake

gentle osprey May 22, 2018, 3:54 PM

If you edit the mesh, and look at your UV Maps, you should be able to tell

"rkitect: I think the only lower increment I can go on refraction is 0 for this instance but I may have to" To disable refraction you have to set it to 1

normal river May 22, 2018, 4:02 PM

But sometimes they use channel 2 (messy channel) and Unreal never give me a warning or error I dont know why

is BSP/CSG not supported by Lightmass?

pale prairie May 22, 2018, 4:08 PM

are you using SSR for reflections?

paper night May 22, 2018, 4:08 PM

#

nope

#

planar reflections

pale prairie May 22, 2018, 4:08 PM

#

ah

#

makes sense since SSR is always to noisy for me

paper night May 22, 2018, 4:08 PM

#

im not using SSR because my target platform is VR and SSR is kinda screwy with VR

#

and that

pale prairie May 22, 2018, 4:08 PM

#

they look amazing btw

#

really clean indirect lighting as well\

paper night May 22, 2018, 4:08 PM

Thank you!

After working with lighting for 3 years in Unity and jumping to UE4, i'm pretty shocked: thing's fucking powerful

royal osprey May 22, 2018, 4:09 PM

planar reflections do work in VR, just limit yourself to one.

pale prairie May 22, 2018, 4:09 PM

#

yeah lol

paper night May 22, 2018, 4:09 PM

#

Yeah, that's what I'm using, dann

#

I said that SSR doesn't work well with VR, not planar

royal osprey May 22, 2018, 4:10 PM

#

Last time I did a lightmap in Unity it came out fantastic, I used octane to bake it. it took a while tho.

paper night May 22, 2018, 4:10 PM

#

yeah, octane does wonders

#

the progressive lightmapper has some serious issues tho

#

Now now, important question: does UE4's BSP/CSG work with Lightmass?

pale prairie May 22, 2018, 4:11 PM

#

this is just a subjective opinion on my part, but I would recommend adding some sort of grunge or non-uniform noise to the floors specular

ye i will, Alexius

a normal map will do wonders, too

might be your 1024 value is wrong value

paper night May 22, 2018, 4:21 PM

#

huh

#

what the fuck

#

lower.. is higher?

#

LMAO lower resolution values yield maps with higher resolution

#

what the shit.

#

Thanks a bunch for the heads up, @median mural ! You saved me from going nuts here, man.

median mural May 22, 2018, 4:42 PM

#

clearly it's some math stuff we don't know they need to calculate it somehow

#

but texel density would be easier to understand

paper night May 22, 2018, 4:44 PM

#

yeah, that makes more sense

#

BTW, quick question: is there any way to change the resolution of all brushes currently in my map?

pale prairie May 22, 2018, 4:55 PM

#

Ive never heard of CSG before, but its generally better to replace your bsp's with static meshes

median mural May 22, 2018, 4:56 PM

#

there is ¯_(ツ)_/¯

📎 unknown.png

#

and I have no idea how to use it

last time I tried it was a mess

I wish there was simple 2x button

paper night May 22, 2018, 4:58 PM

#

uhhh

#

what's that ratio for?
what are the min max values for?

#

how do I just like

#

"assign all brushes to resolution 4"

median mural May 22, 2018, 5:15 PM

#

I wish it was x2 and /2 button

paper night May 22, 2018, 5:17 PM

#

Also, I just realized that my BSP brushes aren't receiving indirect lighting

#

why is that? :r

median mural May 22, 2018, 5:24 PM

#

well they meant to be replaced by static meshes after you done with your level design

paper night May 22, 2018, 5:25 PM

#

I see.

#

Is there any way to exclude these BSP brushes from the lightmapping process?

median mural May 22, 2018, 5:26 PM

#

make then static or movable?

paper night May 22, 2018, 5:26 PM

#

I decided to transform them into a static mesh but I don't want to delete them incase I feel like subtracting a door or a window.

#

I cant. BSP brushes dont have that option

median mural May 22, 2018, 5:26 PM

well. I not sure I don't use them

Hey, is it viable to use emissive meshes as area lights?

mellow crater May 22, 2018, 6:11 PM

i usually add light actors to control the light-sim more of the emitting material

here for example the emissive search light have 2 point lights to throw light onto their close surroundings.

solemn hawk May 23, 2018, 3:54 PM

What are you using for light baking? A quad core?

#

It should take like 2 minutes to bake that scene

#

I use a i7-4770

#

Iis this a lower configuration?

solemn hawk May 23, 2018, 3:57 PM

#

The more cores you have, the faster light baking will go, something like an AMD threadripper (or intel i9* if you’re made of money) will greatly increase your build speeds, what did you set your lightmass settings?

normal river May 23, 2018, 3:58 PM

@solemn hawk

There is

solemn hawk May 23, 2018, 4:00 PM

Set static lighting level scale (the first one) to one, num indirect light bounces and num sky bounces to 10, and then reset the fourth option down.

normal river May 23, 2018, 4:00 PM

#

The thing its I made other test and I spent 12 minutes max and I dont know why I f I use this geometry the time increase a lot

solemn hawk May 23, 2018, 4:01 PM

#

I’d switch your skylight to stationary, this will help your scene look much brighter.

If you have very high res lightmaps it will increase your bake time

#

@median mural Nothing too tricky here, but the warp looks to be coming from corner to corner so I think you're right

median mural May 26, 2018, 6:47 AM

you can subdivide the mesh to add some support topology

for example this like doesn't look too straight

@stuck crypt https://blenderartists.org/t/addon-uvsquares-v1-4-updated-any-shape-supported/613111 or this
https://github.com/Radivarig/UvSquares git link

stuck crypt May 26, 2018, 6:57 AM

#

Alright I'll look into it further. Perfectly placed pixels doesn't seem to help but it's good practice anyways.
If I subdivide a few cuts it minimizes the effect, but I don't think that's the ideal route

median mural May 26, 2018, 6:58 AM

#

you can also triangulate

#

also try to remove doubles but it's probably not this

stuck crypt May 26, 2018, 7:00 AM

#

How do I triangulate?

#

That plugin looks like it'd do the trick

#

Haha the triangulate just swapped the distortion to the other diagonal. I'll get the plugin thanks!

#

It's probably because the whole surface is at a slight angle as well

median mural May 26, 2018, 8:06 AM

#

@stuck crypt triangulate might help because it's more controllable distortion. Like you can't have unexpected distortion in 3 points. Polygon is divided into 2 triangles and you just don't know exactly there you will have your distortion
it's just something you have to deal with then you have 4 points

#

it's like a chair with uneven legs height. If your chair have 3 legs it's not going to wobble

you have to set the LOD mip gen settings to "NoMipmaps" though or it'll be very low resolution

You can make it higher

The max resolution thing that normally makes it lower? Type in 4096 or 2048 and it'll actually increase the resolution for an HDRI

Well you don't want to use 8k panos for lighting anyway, right? And you can just use 4k plates for the backdrop

dusty gyro May 28, 2018, 12:17 PM

#

yeah ofc

#

it looks good enough with the current resolution too, since its for VR viewing

#

@median mural you might want to check zero's solution for your sky texture resolution

median mural May 28, 2018, 12:43 PM

#

@dark oriole you know that SP resolution independent? You can work in 1k if it's too slow and then export in 4k

dark oriole May 28, 2018, 12:43 PM

#

I did.

#

I'm exporting 38 full texture sets at 8k. That's what's slow.

dusty gyro May 29, 2018, 1:22 PM

#

color variation ?

#

not strand wise, more like some areas around trees or walls where the grass is a bit different

cinder remnant May 29, 2018, 1:32 PM

#

Depending on the climate/season, grass may be brown where the sun shines longer during the day

dusty gyro May 29, 2018, 1:34 PM

#

and your grass may be of a different height around trees/walls

#

maybe some grass patches here and there

#

flowers

gentle osprey May 29, 2018, 2:33 PM

#

my grass looked like the face of a 12 year old trying to grow a goatie, so that image looked pretty good to me.

#

also, @dusty gyro , everything in the dentist scene is interactible and movable, right?

#

xD

dusty gyro May 29, 2018, 2:33 PM

#

uuuuuuh

#

nope 😂

#

all static and baked

#

made in revit, ported to UE with datasmith

gentle osprey May 29, 2018, 2:34 PM

#

Someone gave me a demo hospital room model one time. Everything was movable, so you could throw the opertaing table and equipment out the window.

dusty gyro May 29, 2018, 2:34 PM

#

hehe

#

I thought about making a chair with pivot points you can move around

#

but that would break the baked lighting

median mural May 29, 2018, 2:41 PM

#

I wish we could just move baked lighting

#

I wonder what going to happen if you do.

#

I think it's probably something people going to notice less then quality of movable objects

#

oh shadows from the objects

#

that's the thing you will notice

gentle osprey May 29, 2018, 2:47 PM

#

you can spoof it in baked lighting if you put the work into it

#

it won't be very realistic though

#

it will be video game realistic

#

which in a VR environment....?

dusty gyro May 29, 2018, 2:57 PM

#

the solution that kinda worked, with decent results, was to bake lighting but let the interactive stuff movable

#

and then change the type of lighting sampler for the movable meshes

#

to not use point but another setting

#

that way it'll smooth the lighting based on baked data

#

still looked kinda crap compared to static though

pale prairie May 29, 2018, 7:13 PM

#

@dusty gyro try VXGI

#

It definetly needs some optimization but it provides almost bake quality lighting real time

#

Your going to need at least a GTX 980 for VRz tho

dusty gyro May 29, 2018, 7:30 PM

#

VXGI doesn't give as nice results though

#

this is why I've deleted the VXGI branches and went for lightmass :p

did those show up on lower settings too?

#

can you show how you ctrl+0 looks?

@median mural

dusty gyro Jun 3, 2018, 1:36 PM

#

@dreamy sonnet this isn't a normal result at all

#

is your UV tilted by any chance ?

#

ie the pixels are not aligned horizontally

dreamy sonnet Jun 3, 2018, 1:37 PM

#

uh

#

could be

#

but even if we ignore those white dots the whole wall is really noisy

dusty gyro Jun 3, 2018, 1:39 PM

#

yeah absolutely

#

built on production quality ?

#

try lowering the level scale to 0.1

#

I'd be curious too see how your UVs are btw

#

and how much merged meshes are in this scene for your walls

dreamy sonnet Jun 3, 2018, 1:41 PM

#

I think the whole wall around the room is one mesh 😅

dusty gyro Jun 3, 2018, 1:41 PM

#

well

#

there is your problem :v

#

split it into parts

#

and lower the resolution for each

#

a wall shouldn't have more than 1024px res

dreamy sonnet Jun 3, 2018, 1:42 PM

#

it should have enough rolution tho, everything shows up as green / slight yellow in the density view

dusty gyro Jun 3, 2018, 1:43 PM

#

hmm

#

that ain't enough for archviz

#

this is values for games

#

all my debug view is red on small scenes

dreamy sonnet Jun 3, 2018, 1:52 PM

#

well it is meant for a game, but you walk around this room as a really tiny player so every artifact in the lighting is instantly obvious lol

royal osprey Jun 3, 2018, 1:58 PM

#

@dreamy sonnet The most important thing for quick + clean lightmass in unreal is good UVs. But in your case that noise on the wall looks like it's either a compression issue or a shadow issue. First thing I'd try is to use non compressed lightmaps. (look for it in world settings)

dreamy sonnet Jun 3, 2018, 2:04 PM

#

@median mural so I pressed ctrl 0 and nothing happened

#

gonna try the non compressed lightmaps later

dusty gyro Jun 3, 2018, 2:07 PM

#

have you tried purging your swarm too ?

dreamy sonnet Jun 3, 2018, 2:09 PM

#

what does that mean?

dusty gyro Jun 3, 2018, 2:11 PM

#

in the swarm agent (the window that opens up when baking a lightmap) you can clean the temp data

#

sometimes it fixes weird behaviours

dreamy sonnet Jun 3, 2018, 2:11 PM

#

interesting

dusty gyro Jun 3, 2018, 2:11 PM

#

I'm pretty sure youre problem is UV related though :p

#

problems with lighting here are 90% UV related 😂

each wall, floor, ceiling of each room is a different part

#

Can archviz ue4 project (interactive scene) be opened on a web browser but without losing quality?

dusty gyro Jun 6, 2018, 12:09 PM

#

not sure, shader model with webgl/html5 is a bit more limited than the desktop versions

nova seal Jun 6, 2018, 12:12 PM

#

So it would be difficult to achieve this, right?

dusty gyro Jun 6, 2018, 12:17 PM

Would require a lot of tinkering I guess

Never used the web side of ue4

nova seal Jun 6, 2018, 12:21 PM

Is there an alternative option to pack a project that can be opened in all platforms? Not only windows or mac? And also, one scene is around 2GB can this be reduced?

well you can open a project on any platform

about the scene size, you an reduce it by using lower resolution textures and lightmaps

median mural Jun 6, 2018, 8:45 PM

#

it's looks to me that light bounces very poorly if there is no way to use skylight

#

Now I have strange workaround to add some

dusk pelican Jun 6, 2018, 8:46 PM

#

an indoor skylight would make no sense

#

you could try having mesh 'lights' that actually just let skylight light into the mesh by effectively poking holes in the room

#

hidden windows

hard oar Jun 7, 2018, 2:17 PM

#

are they resolving the point light (used with a source radius and source lenght) thing with 4.20? i remember that i had to turn the light shape 90degrees to build it correctly

dusty gyro Jun 7, 2018, 2:18 PM

#

good question @hard oar I can test this out rn

hard oar Jun 7, 2018, 2:33 PM

#

@dusty gyro oh nice it would be awesome if u already have 4.20

dusty gyro Jun 7, 2018, 2:34 PM

#

so the point light length goes upwards

#

but it matches the debug cylinder

#

so I guess they fixed it ? 🤔

but this thing doesn't work with gpu baker so I jsut used emissive lights that work better with gpu baker

the gpu lightmass plugin doesn't work on 4.20 does it

it's not compiled for it yet since 4.20 hasn't come out

dusk pelican Jun 7, 2018, 4:39 PM

he doesn't do previews?

solemn hawk Jun 7, 2018, 6:40 PM

#

I'm not going to speak for luoshang, but I wouldn't if I was developing it, previews change quickly and are buggy

vast wadi Jun 7, 2018, 7:14 PM

#

does the GPU baker produce the volumetric lighting samples for dynamic objects?

dusty gyro Jun 7, 2018, 7:20 PM

#

@solemn hawk in all cases luoshuang is now working directly with epic on lightmass, so he probably dropped the current implementation to focus on the now official stuff

median mural Jun 8, 2018, 4:38 AM

well this will make me stuck on 4.19 then

once the revit plugin is released

we're gonna get reaaaally close to a one button workflow

and help construction managers to visualize the site

dusty gyro Jun 8, 2018, 1:54 PM

exactly

#

I'm excited to see what kind of improvements they made with the LOD stuff

#

since our projects are very, very complex from a model perspective

our engineers dont care about realtime rendering performance

they care about getting all the needed details to build the project

doesnt look really sexy in max either

I am confused then I should say lightmap, lightmass or baked lighting. Wonder what is correct usage of those words 😃

dusty gyro Jun 8, 2018, 6:21 PM

lightmap = texture generated by the engine with baked lighting

#

lightmass = rendering engine to calculate lightmaps

median mural Jun 8, 2018, 6:22 PM

#

isn't it swarm?

dusty gyro Jun 8, 2018, 6:22 PM

baked lighting = process of baking lights with lightmass to create a lightmap 😄

#

swarm is the coordinator

solid oxide Jun 8, 2018, 6:22 PM

or is baked lighting the final result

lightmass is most confusing one because it could be just called baker or something

#

and you want to say things like "how to calculate my lightmass"

#

but you actually calculate lightmaps with lightmass

#

this is what confusing for me

#

lightmass != lightmap but word actually doesn't sound wrong

well planar reflection trick I thought I can do not going to work

how that works? You can access it via blueprints?

dusty gyro Jun 12, 2018, 11:54 AM

#

yep @median mural

#

still missing some stuff though imo, like accessing the references in the "datasmith scene actor" which acts as the coordinator for your datasmith import

median mural Jun 12, 2018, 11:56 AM

#

So you can show data like amount of light in the room?

dusty gyro Jun 12, 2018, 11:56 AM

#

if you had it in revit yep

median mural Jun 12, 2018, 11:56 AM

#

and air

dusty gyro Jun 12, 2018, 11:56 AM

#

yeah volumes for example

#

just a matter of filtering the right kind of data

#

heck I even have the heat transfer for some models

median mural Jun 12, 2018, 11:57 AM

#

well it makes me want to do some stuff like you do

#

big and industrial 😃

dusty gyro Jun 12, 2018, 11:57 AM

#

:p

median mural Jun 12, 2018, 11:58 AM

#

you can do some fancy presentations with that

dusty gyro Jun 12, 2018, 11:59 AM

#

even with just the base product viewer you can do some nice stuff with the xray mode

#

could imagine doing a widget to display info on highlighted object

median mural Jun 12, 2018, 12:02 PM

#

or quickly create cinematics with updatable information in a living project

dusty gyro Jun 12, 2018, 12:03 PM

#

yeah

I see how it's good for your use case 😃

dusty gyro Jun 12, 2018, 12:08 PM

#

thats the tip of what we want :p

median mural Jun 12, 2018, 12:09 PM

#

I need to learn how to match video to ue4 3d stuff

#

like overlay things

dusty gyro Jun 12, 2018, 12:09 PM

#

as in mixed reality ?

median mural Jun 12, 2018, 12:10 PM

#

oh yeah it's basically AR

#

huh

dusty gyro Jun 12, 2018, 12:10 PM

#

epic released a template for this specifically

median mural Jun 12, 2018, 12:10 PM

#

for studio or everything?

dusty gyro Jun 12, 2018, 12:10 PM

#

nah everything

median mural Jun 12, 2018, 12:11 PM

#

cool got to find project for that

dusty gyro Jun 12, 2018, 12:11 PM

#

go in the learn tab in your launcher

#

scroll a bit down

#

should be the first one in "Engine Feature Samples"

Does someone know why some objects wont throw shadows all of a sudden? They are set to szatic, lights too, tried to import them to new scene. They even got “cast shadows“ activated and the lightmap resolution is high enough. I tried almost everything and i cant figure out whats wrong, for the life of me :(

cinder remnant Jun 12, 2018, 1:09 PM

#

Did you bake light?

marsh widget Jun 12, 2018, 1:12 PM

#

Yes ofc

#

Im still experimenting while we are talking what the cause might be

#

I have an older project where everything worked. Somewhere aling the way it broke or i just changed sth idont remember that is causing thid

median mural Jun 12, 2018, 1:46 PM

#

@marsh widget are one sided objects?

marsh widget Jun 12, 2018, 1:49 PM

#

No

#

Its a meshe, closed

median mural Jun 12, 2018, 2:05 PM

#

it's some sort of strange material?

marsh widget Jun 12, 2018, 2:45 PM

#

No

#

Its alrighr ty, i just went back to my old project, because i tried all and dont know what causes it. Thx anyway alex 😊

Unreal is weird like that.. I have spent 5 hours today trying to remove a black spot, like a shadow, from a chair and I just gave up. I have 15 clones of that chair, and all of them look great, just this one.. I have tried upping the lightmap res, tweaking the UV, moving lights, replace it with another clone, move it and rotate it a little.. the black spot refuses to go away.

gentle osprey Jun 12, 2018, 8:30 PM

#

have you moved your change from your left pocket to your right pocket?

royal osprey Jun 12, 2018, 8:30 PM

#

That must be it

median mural Jun 13, 2018, 2:17 PM

#

I love arch viz process in ue4. It's naturally support that thing there you assemble everything for render in one file and create stuff and assets in another. Makes managing everything a lot easier

#

like sharing stuff between project was a bit of pain before for me

dusty gyro Jun 13, 2018, 2:33 PM

#

yeah the migrate option is really nice

gentle osprey Jun 13, 2018, 3:06 PM

#

@dusty gyro , seen this while using 4.20? https://i.imgur.com/w6D0lk6.png

Imgur

dusty gyro Jun 13, 2018, 3:08 PM

#

have you updated datasmith ?

gentle osprey Jun 13, 2018, 3:08 PM

#

@median mural can you clarify that comment a bit? I still find it a pain to move assets from one project to another. I actually wish there was a way to make a shared asset between projects so that if I modify a material for the better, I can go back and easily use it in a previous project underway without having to migrate it from another project

#

@dusty gyro yes, I updated datasmith exporter in 3ds to the preview exporter also

median mural Jun 13, 2018, 3:08 PM

#

well I am totally doing a bad thing and using one project for all my arch viz

dusty gyro Jun 13, 2018, 3:08 PM

#

I'm not sure you can do crosslinking with unreal

gentle osprey Jun 13, 2018, 3:09 PM

#

verified that 4.19 can still build a project succesfully with datasmith files

#

maybe I need to reinstall 4.20?

dusty gyro Jun 13, 2018, 3:09 PM

#

this what you have ?

gentle osprey Jun 13, 2018, 3:09 PM

#

I'm pretty sure you cannot crosslink with unreal, and I can understand why as well.

dusty gyro Jun 13, 2018, 3:09 PM

#

4.20.0 datasmith plugin version

gentle osprey Jun 13, 2018, 3:09 PM

#

that's jsut what I wish

dusty gyro Jun 13, 2018, 3:10 PM

#

ooh you want to compile 4.20 stuff ?

#

hmm haven't done it yet

median mural Jun 13, 2018, 3:10 PM

#

shared asset between projects
but apparently content plugins is exactly this

gentle osprey Jun 13, 2018, 3:10 PM

#

oh, is that my problem, that I'm building the packages?

dusty gyro Jun 13, 2018, 3:11 PM

#

your exporter looks like is has the right version

#

well I have no clue if they changed stuff with the packager

gentle osprey Jun 13, 2018, 3:11 PM

#

@median mural true, but I'm not going to author a plugin just to connect to a shared network folder containing assets :]

median mural Jun 13, 2018, 3:12 PM

#

yes this is why I just use one project called Arch Viz and there is folders for every project I am doing now

dusty gyro Jun 13, 2018, 3:12 PM

#

yeah this is what I have for the material library too right now

#

I just migrate it to new projects if needed

median mural Jun 13, 2018, 3:12 PM

#

📎 unknown.png

#

So Arch viz is main thing
colored folders is projects

gentle osprey Jun 13, 2018, 3:13 PM

#

are you packaging EXEs for clients or just generating raw images to process and send to clients?

median mural Jun 13, 2018, 3:13 PM

#

I don't have any reason to create separate project atm

dusty gyro Jun 13, 2018, 3:13 PM

#

wait you have just ONE project @median mural ?

#

dem load times 😐

median mural Jun 13, 2018, 3:13 PM

#

idk it's fast enough

dusty gyro Jun 13, 2018, 3:14 PM

#

well you have a lot less stuff in your projects than we do I guess

#

since you do small scale interiors

median mural Jun 13, 2018, 3:14 PM

#

I assume that working on a big game is the same if I put all the arch viz in one folder

gentle osprey Jun 13, 2018, 3:14 PM

#

fair point

median mural Jun 13, 2018, 3:15 PM

#

yeah with packages you can just export folder of project if you need to

#

📎 unknown.png

#

like that

#

to a new project for packaging

#

it should export everything with dependences

#

so every folder is basically a project but they are combined together for ease of use

#

as I understand plugin is the same but you open separate ue4 instance and that might work good too. not sure if you need to restart if you change stuff

gentle osprey Jun 13, 2018, 3:32 PM

#

Coming from the world of worksharing in AEC it's hard to imagine a team of game developers working in this environment

#

how do multiple people work on one project?

#

I'm interested in that

median mural Jun 13, 2018, 3:38 PM

#

we have level streaming for that

#

problem is that files are binary so most of the thing require one user to work on it
so if you use source control you block this file from editing by other people

#

so you need to create things in small level chunks that can be worked by several people. So someone doing lights in the level going to use specific level that loads lights in the scene so this peroson only edit lights level in streaming levels

#

gentle osprey Jun 13, 2018, 3:56 PM

#

interesting. thanks!

#

oh man.. if our network were so rediculously slow I would be trying this out!

#

I have an intern who desperately wants to get into this VR development, but it's tought o supervise AND get work done at the same time without something like this

median mural Jun 13, 2018, 4:14 PM

#

I am not sure if it possible to see changes in real time

#

at least with git you will need to download changes and then reload level

#

and it will not lock files for you so there might be issues

I want to make a 360 panoramic video of my archviz scene so it will be able to open on YouTube. I did some research and I found that the way to do this is to enable the MovieCapture plugin. Is this the only way to do this, because the documentation is from version 4.13 and it seems a bit complicated, or there is some easier way?

gentle osprey Jun 13, 2018, 9:28 PM

#

photo or video?

cinder oriole Jun 14, 2018, 6:55 AM

hey folks

#

so i do archviz, but i'd like to discuss bp issues i am having, a bit of dilemma here or #blueprint channel 😛

#

or both

#

i lean to bp, but just came to check anyway

glossy creek Jun 18, 2018, 2:34 AM

#

I'm looking for the best way to change the materials on multiple static mesh walls. So far, my solution was to select all the walls I want to effect, and drag it into my BP. Not very effective. Is there a way to group a set of SM so I can refer on them in the BP. Or is there a whole 'nother way to go about it?

#

I should clarify my question. This is for a interactive walk through, so white wall, blue wall, etc. Looking for the best way go reference a "group" of SM.

dusty gyro Jun 18, 2018, 6:50 AM

#

@glossy creek there's multiple ways to do this ! 😃 My method was to store these groups of meshes into an array via a structure (the STR was made of a name, an array of mesh actors/components references, and an array of materials). When you raycast your mesh, you can get the group name associated with it, as well as all the available materials for that group !

glossy creek Jun 18, 2018, 1:01 PM

#

@dusty gyro Thank you! I'll look into that!

gentle osprey Jun 18, 2018, 1:32 PM

#

This is the problem I was trying to resolve by continuing to use DAE files which groups meshes by material from the revit export
