I'll give it a try again, I remember the feature set wasn't really there yet last time I checked

[past echo]

Yeah, I just tried msaa, looks horrible even with the samples maxed out. Way too noisy.

[dusty gyro]

[ancient pasture]

I need to ask again in this channel 😦 I already shared my problem yesterday but because I rlly need to finish this scene I´m pretty dependent on you.. I still have these weird shading errors that are probably caused by the lightmaps in UE4. In my scene there are 5 objects that give me the overlapping lightmap error after building lights. what I´ve tried so far is:

• unwrapping every object at least 4 times with different applications such as 3ds max or rizomUV + checking the padding between the UV islands
• increasing the lightmap resolution to 1024 just to check if that might cause it; didn´t help either

another thing is that I still wasn´t able (even though I googled for at least an hour) how to visualize the overlapping... I enabled "use error coloring" in the build options but where should I see the errors now? I can´t see them neither in the viewport nor in the lightmap

[wraith hare]

Hi, I was wondering, have any of you worked extensively in photogrammetry before

[dusty gyro]

@dark oriole has

[wraith hare]

I started out looking into Photogrammetry for environment work, but am becoming increasingly interested in it for archvis

Would love to have a chat to someone who can perhaps mentor me a bit within the area (perhaps beyond what i can gleam from youtube tutorials)

[sweet fossil]

What do you mean by use it for archvis?

[marsh dragon]

Im guessing for prop creation. you'll need an area with really even lighting at multiple angles, any single obvious light source (for example, a light thats way too bright, or un even lighting that the sun, and ceiling lights with no lighting come in at the sides can cause) will mess with the render and most likely make it useless for UE4. Because that obvious light that's baked into the textures wont match the lights you have ue4

oh you asked for beyond what you can learn from YouTube vids, ^ thats pretty general info sorry

[wraith hare]

I'm considering attaching a diffuse light to my camera and taking photographs at night from all angles, do you think this set-up would be good for an interior, or not?

[pearl maple]

Hey all, I have been working on this project which is replication of a irl project in VR. I can't change materials and models but can rearrange them, What do you guys think of the lighting here? What could be improved?
https://imgur.com/a/0G91V7U

[dusty gyro]

@pearl maple looks pretty fine already !

[pearl maple]

Yeah, but I have been looking at other projects and it doesn't feel its finished. Could be because of the materials and lack of models.

[dusty gyro]

definetly lack of props

the bedrooms are quite empty

[pearl maple]

I know, But I can't add anything else to it.,

[dusty gyro]

living room looks nice, not too crowded

care to post a shot of the kitchen ?

[pearl maple]

https://www.youtube.com/watch?v=8wHD54C6gEA

Take a look at that one, I think the reflections could use more work.

Or maybe post processing could use more work to create a better mood?

[dusty gyro]

PP can add quite a lot yeah

be it color grading, bloom, dof (not for VR)

[pearl maple]

Yeah no dof, What would you suggest color grading wise, I have mot a lot of exp there.

[dusty gyro]

I dont have any sadly :/

that video you posted

its using a lot of closeup shots

DOF abuse

and very detailed materials

[pearl maple]

Yeah I know, Just an example though and materials - I only got a 512px image from vendor's site so that's the best I could do.

They can be better

[dusty gyro]

argh

do you have substance designer ?

you could try to recreate that image procedurally

or something close to it

[pearl maple]

Yeah I thought of that but Imagine doing that for 100+ materials not really feasible.

[dusty gyro]

nah, takes a lot of time

have you got roughness / metallic / normal maps ?

or is it just diffuse/basecolor textures

[pearl maple]

Most of them have diffuse/roughness/normal

I used bitmap2mat

[dusty gyro]

alright

better than nothing 😃

[pearl maple]

Yeah

Its still looks good - Like the client is happy and all. I am just wondering if it can be improved further.

[dusty gyro]

hmm

you could use a low resolution planar reflection for the TV screen

instead of a sphere cubemap

or at least use a box reflection instead of a spheremap

that'll correct the slightly curved window reflection

you could also try to use lighting scenarios

and light up these ceiling spots

be it in the living room or the bedrooms

[pearl maple]

Yeah I can't add any artificial lights, I will try to do the box reflections, One thing I was stuck at that when looked from afar sphere refs looks better - It merges well with the rest of them,.

[dusty gyro]

yeah box can look a bit weird sometimes

I like planar reflections, but the performance impact can be quite big

[pearl maple]

How do you do reflections for mirrors?

[dusty gyro]

on a small scene like that it shouldnt be too heavy though

Planar Refs

[pearl maple]

and planar might not be the best idea its for VR after all.

[dusty gyro]

well if you stick with a slightly rough material and a planar ref with a 30% resolution

it might be good enough

just dont abuse it (or toggle them on/off depending which room the user is in)

[pearl maple]

I will try to set it up, Never used that before. Right now I have box ref for mirrors and it looks weird because it fades in when you walk to it xD

[dusty gyro]

ah

your lighting natural lighting setup looks pretty good already

so reflections, materials and PP will be your best bet to improve the scene

[pearl maple]

Yeah, Thanks! 😃

[dusty gyro]

some props here and there can add quite a bit to a scene

[pearl maple]

I see what you mean.

[dusty gyro]

it makes it a little more lively

[pearl maple]

This is actual apartment and they wanted exactly that.

[dusty gyro]

ah well

the client is king

are the tiles you used for the kitchen the same as the ones in the photo ?

doesnt look like it

photo tiles are a lot less rough, and smaller with a white seam

[pearl maple]

Yeah I have those as well, You can change materials in VR.

[dusty gyro]

nice

[lucid orbit]

if im understanding correctly, theres no way to get non-opaque shadows casted from glass-type materials, while keeping ray-traced reflections on them?

im thinking about the glass floor kind of, in skyscrappers or on top of giant well

glass paths as well, like ones on some chinese mountain 😛

https://i.dailymail.co.uk/i/pix/2011/11/10/article-2060023-0EBEF4C000000578-970_634x416.jpg

[digital wasp]

can someone explain why is that mesh getting illuminated like that? I dont have any lights in the scene except one skylight with hdri plugged in. those spotlights have zero intensity. it feels like light is passing through the walls and illuminating objects

[lucid orbit]

maybe light is leaking through roof into this wall?

you could test it by putting scaled ue4 cubes to block

@digital wasp

[digital wasp]

I will try it. thank you

[digital wasp]

after inspecting for hours, turns out ue4 was recomputing wrong normals for the mesh. and hence incorrect shading on some faces 🤦

[pearl maple]

well atleast you figured it out! 😂

[sleek cove]

Hello everybody!

[pearl maple]

Does anyone know how to save static meshes with baked lighting so they can be replaced at runtime?

[digital wasp]

@pearl maple I dont think you can save the static meshes with the lighting information baked on it because UE4 overlays the encoded lightmaps on top of the meshes and those lightmaps are saved with the level. if you want to swap the meshes in runtime, then you can prebake the lighting with some other renderer like cycles in blender and then export out the light textures and then apply them to the swappable objects in UE4. you will have to use unlit material. but this is a lot of work just to swap meshes in runtime

[pearl maple]

Yeah no, UE let's you save light maps for unwrapped objects, found it later.
https://docs.unrealengine.com/en-US/Engine/Content/Tools/RenderToTextureTools/2

[sleek cove]

Got Google's Text To Speech cloud API working in our project. Now it is easy to type anything you want user to hear. For example in virtual exhibitions inside arch viz buildings 🤓

[digital wasp]

Wow! this is soo cool 👍

[dusty gyro]

@pearl maple is that a real foto or render!? if its a render damn! if its a foto, it makes sense it looks real 😄

[pearl maple]

Lol yeah the last one is a picture, Imagine making something like that though 😃

[solemn prawn]

So how does the Unreal and TwinMotion integrate? It appears TwinMotion is a separate program. Opening up the Unreal engine doesn't reveal any type of component connectivity.

[solemn hawk]

There isn’t any yet, it’s a standalone program

I remember the datasmith guys talking about making a bridge between twinmotion and unreal though

[solemn prawn]

Twinmotion needs a 3D Max import option.

[dusty gyro]

I guess down the line Twinmotion will have datasmith support @solemn prawn

Would be missing out if it doesn't

[uncut jolt]

did Unreal not bought Twinmotion?

[dusty gyro]

They did

But it takes more than a finger snap to add features ;)

[uncut jolt]

yeah takes more that 😛

[blazing furnace]

Hi, I have tried to use Landscape Grass to get my lanscape to spawn grass based on the landscape material layer. It works technically but I cannot get it to perform. I use Quixel Megascans assets that have lods and seem to be made for this purpose ( preview rendering of the asset from quixel shows the asset rendering in UE4). I have tried to use it as regular foliage as well but I get the same problems, It seems to be related to overdraw since most of the screen is colored "white" in the quad overdraw visualizer mode. Anyone have tips on how to get this to be performant while still looking like grass?

[gusty urchin]

Hi everyone, soory a noob question.
I textured a picture frame prop and when I apply the textures into a material with the opacity alpha channel, the whole prop is transparent

I have no idea what type of material I should use

This is what I get, I'm a noob at UE4 material editor

[dusty gyro]

blend mode "opaque"

in your detail window

do you even need your material to have an alpha

[gusty urchin]

I have a glass frame plane on top, it should have it right ?

[dusty gyro]

if you have a glass frame, assign it to a different material

[gusty urchin]

this is what it looks like in Painter

Oh so separate them

I see

Thanks 😃

[dusty gyro]

yeah

[gusty urchin]

Will do

[dusty gyro]

keep it a single mesh, but use two material slots

even cheaper

use opaque

but instead of using a separate material for the glass frame

just use a low roughness value on the framed pic

[gusty urchin]

great! thanks 😃

[past echo]

does anyone know how to get the new mesh instancing to work with a movable direct light, it only seems to work with a static light

[solemn hawk]

has anyone else had issues packaging with the substance plugin in 4.22?

[blazing furnace]

Here is an image of the current state of my Landscape Grass:

way to sparse and at the limit of what my gpu can handle. Quite far from what I have seen others do.

Material is very simple Landscape material for test:

and the Landscape Grass types:

this is one of the Quixel grass meshes:

and finally the material for the grass:

Sorry for spamming with all this info, but if anyone has some input on how to make this look nice, I would greatly appriciate it!

[dusty gyro]

you should defo be able to get much better results @blazing furnace

[blazing furnace]

Yes, I think so, don't get what I do wrong here. been at it for two days with lots of issues. I have searched this forum and saw that you made some quite nice scenes.

yesm like that!

[dusty gyro]

this is what i get with the Photorealistic Bagrounds package that was free a few months ago on the MP

the grass is reactive to the player even

I'm also using the OpenWorldFoliage package

for the grass assets and logic

[blazing furnace]

Cannot find these packages on the MP.

[dusty gyro]

hang on

"interactive Open World Foliage"

is the pack you want to look at

[blazing furnace]

this: Open World Foliage

[dusty gyro]

yup

the screen I posted is my Landscape Grass Type asset for the furnished grass type

(I've got three, one of em is for rock scattering)

[blazing furnace]

Ok, will buy and test this

[dusty gyro]

what GPU are you running ?

[blazing furnace]

Just hoped that the assets from quixel would work

this is on both a Mac with Vega64 and a PC with rtx 2080 ti

similar performance

[dusty gyro]

hmm yeah defo not normal then

I'm running an RTX Titan

but the 2080ti should give similar results

[blazing furnace]

yeah. I better try this out and report back.

[dusty gyro]

👌 ping me when you've got your firsr results

[blazing furnace]

sure, I will! thanks for the helkp

[blazing furnace]

painted in the most simple way

@dusty gyro seems that the foliage pack you suggested works fine. now I have to try to understand why

[dusty gyro]

😃

hang on

are you using translucent/masked ?

on your quixel mesh

[blazing furnace]

masked yes

[dusty gyro]

thats the issue

overdraw

[blazing furnace]

overdraw

[dusty gyro]

haha

that package I've redirected you to is using meshes

[blazing furnace]

hehe, yeah but quixel sets up the whole thing for you so one expect it to work out of the box

[dusty gyro]

like, grass meshes, instead of planes

true

[blazing furnace]

maybe there will be less overdraw using the highest (0) megascan lod since I believe it is just a mesh

[dusty gyro]

surely

[blazing furnace]

sadly it is at 5000 triangles or so :/

I guess it is made for offline rendering mainly

in clarisse or so

[dusty gyro]

ah

yeah, the open world foliage is ~230 triangles for a grass patch

[blazing furnace]

Overdraw viz shows that this maxes out at "green" while the quixel one paints almost the whoel screen white . I guess one could make good use of the quixel assets but it will take a lot of tweaking to have very little of the shape be masked out

[dusty gyro]

you could use the quixel meshes

and run the decimation tool on it

(ie mesh reduction percentage to something like 10% or even 1%)

[blazing furnace]

True, will probably look into it but it is not really top prio for now since then I have to set up everything myself for each asset and that will take quite some time

[digital wasp]

Static skylight or stationary skylight for lighting interior with overcast lighting situation(no direct sun)?

[tidal skiff]

@digital wasp do you need to change the light properties at any point

if yes, stationary

if no, static

[digital wasp]

I dont need to change any light properties. but I heard that stationary lights produce better quality

[tidal skiff]

not if you get the lightmass/lightmap setting right

also does performance matter

sky lights i think i'd put stationary for them though since you get bent normal occlusion

but all other lights static

https://docs.unrealengine.com/en-us/Engine/Rendering/LightingAndShadows/Lightmass

also if you're using IES profiles they dont work well with static

[digital wasp]

I have a long room with one big window. I want to light the room such that it is filled with soft lighting. I have lightmaps for wall and floor set to 2048 resolution, lighting scale of 0.6, skylight bounce of 10, indirect lighting quality of 2 and smoothness of 0.7. I baked with production quality but I cant get the whole room to light properly. its not bad but its not realistic enough. the part of room which is close to the window is very bright but the parts away from the window are very dark. and if I increase exposure settings, the part close to window are just blown white

[tidal skiff]

put a lightmass portal that fits perfectly into the window

see how that affects it

[digital wasp]

yeah I tried that too. while lightmass portal does makes the quality better and reduces splotches, it doesnt make the scene any brighter

[tidal skiff]

you could use a tonemapper

or skylight

[digital wasp]

didnt try the tonemapper. willgive it a shot too

[tidal skiff]

its hard to say exactly what to do without having seen it as well

[digital wasp]

I will post some screenshots soon. currently building lights again using stationary skylight

is there any noticable effect if I crank the number of skylight bounces to something like 70-80? I am using 10 right now

I read a blog post on 80.lv about realistic lighting study in ue4 where the guy said that he set the number of indirect bounces to 100

[dusty gyro]

10 is more than enough

Most of the time

[gusty urchin]

Hi everyone. Sorry again with my noob questions. is there a way to export a complete scene in UE4 and import it into an existing level ?

[cyan ether]

https://i.imgur.com/ppLQa42.gifv

[tidal skiff]

What are the differences between unreal studio and normal ue4?

[blazing furnace]

seems to be a plugin for importing things from 3ds and revit and a few extra bundled materials mostly. you can download regulat ue4 first and the install the studio plugins afterward

[cyan ether]

datasmith convertors and an in engine mesh editor which imo should be in vanilla ue4 by now

[blazing furnace]

anyone understnad the Grasstype scalings? X seems to be a "universal scaling in all directions" while Y and Z doesn't change anything. note per axis scale as I would have assumed

at x= y = 1.0 :

and at 10.0:

but changing X scaling slightly:

[warm slate]

hi iam new wanna share what iam working on with u awesome people 😄 O/ sci fi env wip more update soon

really nice @warm slate 😄

[warm slate]

hi yehoo 😄 thx u

[blazing furnace]

this is a real mixed forest close to where I live:

I wonder how close we can get in real time with current tech

[spice sapphire]

ive seen some pretty good workflows with photogrammetry

that could work with that forest, pretty much involves "scanning" the area and then decimating/simplifying a mesh

[strange stream]

Hi ... Do you know how can I use hdri image in twinmotion ?

[dusty gyro]

@strange stream you cant... yet, hopefully 😬

[strange stream]

@dusty gyro but I have found a youtube video for someone used a TIM file as an hdri image , so How can I convert an hdri to TIM (honestly I never heard about this type of file before today ) , I searched in google for that with no success

[dusty gyro]

TIM ? Never heard of that either

[strange stream]

ah TMI files, not TIM

ToneMapped Images

yeah, no clue how to convert hdris to TMI

yeah sorry typing mistake 😅

I cant even see where can I download such an images

[dusty gyro]

nah I'm good @forest depot 😃

which one were you on the webinar ?

[forest depot]

im jason : D

[dusty gyro]

Hi Jason o7 I was Antoine G

super good stuff you guys have done btw

the projector idea was great

[forest depot]

[dusty gyro]

I did something similar with light functions a while ago

[forest depot]

oh i loved that room, really showed off how RT can do a lot without pushing performance

[dusty gyro]

absolutely

[forest depot]

you guys use rtx cards for archviz?

[dusty gyro]

we do have one Titan RTX

but uuh, IT doesnt want to update windows to 1809

so we're stuck with baked lighting 😦

[forest depot]

ahhh do you work in a big company?

[dusty gyro]

decently size I'd say

gonna leave soon tho

to join the datasmith team 😃

[forest depot]

we're like... 15 people

so

[dusty gyro]

haha

I'm 1

[forest depot]

yeah i am IT

lol

I'm the single VR/realtime guy at the current company

[forest depot]

out of how many?

[dusty gyro]

1200 or something ?

[forest depot]

:0

[dusty gyro]

lemme check the numbers

its a Building Engineering and construction company

https://www.groupe-legendre.com/en/

[forest depot]

thats a lot of weight on your shoulders

[dusty gyro]

yeah

part of why I wanted to leave too

[forest depot]

i see

[dusty gyro]

being able to work at Epic is an awesome opportunity

cannot wait

[forest depot]

buildmedia isnt just realtime so for a while i was the only realtime artist

yeah that is amazing

[dusty gyro]

so how many people worked on the showcases you streamed ?

[forest depot]

mostly just tim and myself

[dusty gyro]

damn

makes it even more awesome 👌

[forest depot]

yeah most projects i just start from scratch

from architects plans to baked with all the visuals done

then i just pass it to tim to do the UI stuff

[dusty gyro]

aight

thats how I worked too

get the plans, maybe a BIM model or two

and then build over it

[forest depot]

receiving client models is no fun

[dusty gyro]

no kiddin 😂

[forest depot]

just best to redo it lol

[dusty gyro]

datasmith is a huge lifesaver

[forest depot]

yeah i remember asking here before if people found it helpful

[forest depot]

but i really havnt been using it

dont tell tehm i said that 😉

[dusty gyro]

thats the latest I've used

hehe

no worries

its still in beta after all

this is the article where we showcased our stuff

as you can see we have some pretty big models

[forest depot]

so pretty much all of the article's highlights is your work

[dusty gyro]

yup

I mean

the modelling of the projects (ie the buildings) are from architects

[forest depot]

ah yeah

[dusty gyro]

I'm doing the integration in UE, coding, artist stuff

[forest depot]

oh wow

[dusty gyro]

lighting, materials, etc...

[forest depot]

i dont do any coding, practically zero codiing skills

thats impressive

@dusty gyro u were Antoine G? 😛 i remember u from the webinair with the large urbain project in dubai XD

[dusty gyro]

haha yeah thats me 😃

thanks @forest depot

its a blessing and a curse

[forest depot]

i can see that

[dusty gyro]

because companies want you to do everything 😂

[forest depot]

i just go 'i dont do code'

[dusty gyro]

in impossible deadlines sometimes

yeah 😄

[forest depot]

would be interesting to try datasmith for some larger archi projects

we seem to be getting mostly apartment interiors though

[dusty gyro]

it works really well for massive projects

even more with the dataprep tools

hang on I should have a couple screenshots of big projects

[forest depot]

yeah have you tried optim?

[dusty gyro]

once

and it crashed

[forest depot]

ha

[dusty gyro]

so I removed it 😅

I'm much more proeficient with the UE tools

[forest depot]

well the idea of optim is what i want datasmith to do

[dusty gyro]

ie autolod, lightmap generation etc...

it'll get there

dataprep is pretty much wip, and can change a lot

[forest depot]

most of the time i do lightmaps by hand >_>

but again, interior details

kinda different job

[dusty gyro]

ohno

😄

[forest depot]

once RTGI is better we can say bye to unwrapping : D

[dusty gyro]

eeh

I'll be good with just GPU progressive lightmapping 😄

[forest depot]

[dusty gyro]

actually I've got a two slide showcase to post

https://i.imgur.com/y43WNSY.png

https://i.imgur.com/FQzrTmW.png

well

it depends a lot

either its really good

lots of details, very good base to work on

or its disastrous

and you have to cut corners all the time

[forest depot]

cause would you go straight from their model to datasmith

we do all prep in max

so even the best model we receive id still be prepping in max

[dusty gyro]

if its all well done (ie they did their part of the work well in Revit for instance) I'll straight up import a datasmith export

I used to do a max pass

[forest depot]

: o

[dusty gyro]

but honestly, I had so much shit models even max wouldnt open them

[forest depot]

this is receiving models from inside your company though?

[dusty gyro]

inside the company nah, we have good CAD modelers

outside

eeh

[forest depot]

ah right

[dusty gyro]

50/50 chance of it being done right

[forest depot]

sounds about right

[dusty gyro]

https://i.imgur.com/WddUARx.png

this one was a good model for example

oh dear

[dusty gyro]

I had to abuse the lodding and mesh reduction tools

[forest depot]

id just take that into max and delete it

[dusty gyro]

thats the problem

we cant

😬

because every part of every model has precious BIM information tied to it

[forest depot]

oh no......

[dusty gyro]

:p

[forest depot]

im so glad i dont have to deal with that at all

[dusty gyro]

thats why datasmith helped us a lot

https://i.imgur.com/IcmONND.jpg

that was the prototype of the bim information display tool

[forest depot]

this is beyond my understanding of architecture : P

[dusty gyro]

its pretty deep stuff

I still cant quite wrap my head around most of these concepts

I'm a gamedev at heart, so it was a weird step into realtime archviz 😅

hi guys iam new here what you guys working on looking really interesting

haha yeah

my last job was gamedev as well

Hey Elitetech 😃

[forest depot]

hey 😃

[dusty gyro]

nice shot you've posted

[warm slate]

hi thanks 😄

what are you guys working on looks really neat 😄

[dusty gyro]

Building Information Modelling

[warm slate]

?

😄

[dusty gyro]

long for BIM 😄

[forest depot]

if youre awake for another few hours... i have presentation to show you haha

[warm slate]

iam here 😄 are you going to post it here 😄

[dusty gyro]

well its like 5PM here

[forest depot]

its 3am now 😦

[warm slate]

5 pm here too 😄

[dusty gyro]

gonna head home soon, but I'm still around on discord if you ping

[forest depot]

https://ue.unrealengine.com/ON24WebinarProgram2019__LPPromoPage.html

[warm slate]

so are you still up in a few hours @forest depot 😄

[dusty gyro]

3am ? damn go to bed 😄

[forest depot]

sign up to this elitetech 😃

[warm slate]

uhh whats this 😄

[forest depot]

cant tho cause of the live Q&A

[dusty gyro]

part 2 of the webinar

https://i.imgur.com/yWLeauU.png

fix for datasmith with unreal 4.22.2 got released

[warm slate]

ohh yes

[dusty gyro]

mostly small fixes and support for Revit and Max 2020

[warm slate]

are you all using datasmith to transfer informations too unreal ?

[dusty gyro]

yup

[warm slate]

😄 nice

[forest depot]

im not hehe

depends on what kind archviz you do

[warm slate]

i did it once and i dont know feels like too much automatic 😄 maby is just me 😄

[dusty gyro]

UE-71942 Light Intensity Resets to Default Value after Reimporting CAD Asset thats a good fix, was annoying

well, it all depends on the size of the project and what tools your model was made in

[forest depot]

yeah basically

[dusty gyro]

max I'd understand you would use the FBX workflow

[warm slate]

doing mostly in 3dsmax 😄

[dusty gyro]

but with Revit 🤢

Revit itself is such a weird modelling tool

[warm slate]

haha yea 😄

[forest depot]

i dont even have revit : /

[dusty gyro]

at least its not as crash happy as max

[forest depot]

what about when you get sketchup models from clients

[warm slate]

hearing people say that revit is the best tools for archviz

happy to see other people 😄 doing cool stuff 😄 looking forward to see the update post 😄 need to run 😄 take care awesome people O/

[dusty gyro]

god sketchup

revit is a very good CAD tool

just that CAD modelling can be pretty stupid sometimes

and wait till you work with IFC files

god

these are the worst

[warm slate]

yea using inventor and fusion 360 if i need some precision/cad work 😄

or els 3dsmax zbrush 😄

here is some interior WIP for the office real time with interactions sorry for spam but there was alot of good picture enjoy

[dusty gyro]

are you using dynamic lighting only @warm slate ?

[ripe island]

And those shadows look very strong

[honest temple]

Looks very good..
You could perhaps add some Ambient Occlusion to get better shadows..

And perhaps also just a TINY hint of volumetric fog to scatter the light a bit

Done trough post prosses effect

[forest depot]

if anyone missed the previous link we're about to do the webinar again very soon 😃

https://ue.unrealengine.com/ON24WebinarProgram2019__LPPromoPage.html

[warm slate]

@dusty gyro yea is has dynamic day and night cycle 😄 has no other choice with my knowledge 😄

sadly dont have RTX really wanna try that 😄

@limpid cobalt yes i try that but was not looking great with day and night cycle

[forest depot]

still might be interesting if you wanna check out some of our work 😃

[warm slate]

oh what 😄

@forest depot is this you 😄 in the webinar 😄

[forest depot]

yeah im one of the presenters

[warm slate]

ohh wow 😄 you amazing 😄 mann

it looks super awesome 😄

[forest depot]

thanks 😃

[warm slate]

have u try to work with dynamic day and night cycle.. for me ..still having problem to make shadow soft and sexy 😛

[forest depot]

its pretty challenging

[warm slate]

😄

iam pretty new does this cost any money :S and do u need to have RTX :S

@forest depot the webinar ?

[forest depot]

no its free

[warm slate]

it looks like its today 😃

[forest depot]

theres a chance to win a quadro rtx card by joining 😉

[warm slate]

but it says it has all ready started ?

@forest depot sry agian do i need to have a company name ?

[forest depot]

just did yeah

nope

[warm slate]

ok registered now 😄

@forest depot thanks iam in there now 😄 many thx 2 you

@honest temple hello thanks alot yes sadly i cant do. the office have day and night. but i going to try to soft some of them to make it look better hopefully 😛

[honest temple]

Only som AO would make the roof and wall corners darker... but your scene looks really awesome dude! 👍😄

[warm slate]

thanks @honest temple 😄

[lucid orbit]

has anyone watched webinar about rt for archviz?

[forest depot]

yeah i worked on it 😃

[lucid orbit]

well, i wanted to ask what were the most key infos @forest depot

on side, will webinar be uploaded to youtube?

[forest depot]

Yep

Prob won't be long so I guess you could just check out the YouTube

[lucid orbit]

ue4 channel?

[forest depot]

Hm not sure tbh

I dont have anything to do with epic :)

I'll drop a link here when I get it

[past echo]

Does anyone know why using WASD Only When a Mouse Button is Pressed is causing my camera movement to stutter really badly? If I use WASD without the mouse button it is fine.

Thx.

[warm slate]

here we go a little video of the office 😄 sry for my broking english 😛

https://www.youtube.com/watch?v=HUBXiAkxrvk

[warm slate]

@forest depot thanks for the invite and info about the webinar that was really cool and alot of insperation thanks you

[dusty gyro]

You'll get a link by mail with a "videocast" (?) in a few days if you were attending it.

[warm slate]

😄 nice thanks for the cast really awesome 😄 hope u guys doing some more like that

[cyan salmon]

Some easily digestible daylighting information

@dusty gyro dit you see this? https://forums.unrealengine.com/unreal-engine/unreal-studio/1620873-revit-optimization-feedback-needed

[dusty gyro]

yeah I was in the mailing list before this message was posted here 😉

[uncut jolt]

oh lol

@dusty gyro how do you get in the mailing?

[dusty gyro]

@uncut jolt very early tester, also I'll be working in the team in a couple months 😅

[uncut jolt]

@dusty gyro lol u going to epic?

[dusty gyro]

yep

part of the datasmith AEC team

[uncut jolt]

gratzz man!

[dusty gyro]

👌

[uncut jolt]

still trying to get UE4 here -.-

[dusty gyro]

😬

[lucid orbit]

you guys talking about revit, while i remembered how i checked sketchup recently

man, they did a huge turn in direction, fully online from what i remember

i feel sorry for plugin devs

fully online, as in a webtool you use in browser

so i started learning blender recently, 2.8 is pretty 👌

[dusty gyro]

@lucid orbit you sure ? Isnt Sketchup online only for the basic version ?

The Pro licencees have a much more complex editor as a desktop software

[digital wasp]

@warm slate wow I really like the idea of showcasing stuff. its like a virtual art gallery. keep it up 👍

[warm slate]

@digital wasp thanks you i will 😄

[lucid orbit]

@dusty gyro hm, i guess my memory did fail me

[honest temple]

First room done of my HQ_Residential_House pack makeover 😃

[hard current]

hi guys i have a scene on unreal but when i put on vr mobile then i tried cubemap but the quality its very low

sobut with 3d models the mobile vr is very slow

but*

[honest temple]

when you open the cubemap texture, you will see a max resolution

It should be 0 at default i think. Set it to 512 or 1024 (could try 2048 also)

I think this is it..
But i believe it would drain the performance even more

[honest temple]

The stairs and hallway also got a makeover 😃
Free HQ_Residential_House pack from UE market

[hard current]

thanks dude i will try it

thanks

[honest temple]

np m8 😃

[hard current]

@honest temple now i modified it and now im looking it black

[honest temple]

hmm, then i'm afraid i can't help you..
Just set it back to 0 ( or the same as it was )

guess the texture is just low res

[hard current]

but the texture is 6500*3250

@honest temple

[honest temple]

ah, then im not sure

[solemn hawk]

@hard current try increasing the screen percentage, it’ll make it render at a higher resolution

[hard current]

@solemn hawk im triying to find that

but i do not find it

[dusty gyro]

@hard current is that PP blur or are you rendering at very low quality ?

[hard current]

nop high

[dusty gyro]

looks like PP blur then, be sure its disabled in your Post Process volume

could be a cinematic camera with wrong settings too

[dusty gyro]

what am I supposed to see here ?

[mild oxide]

pp blur lmao

Pls dont ban me

[uncut jolt]

@mild oxide pp= post processing

[mild oxide]

y aik

first time ive achieved lighting this good

feelsgoodman.jpg

[dusty gyro]

looking smooth @mild oxide

[mild oxide]

😄

[forest depot]

Looks clean :)

[mild oxide]

i want the shadows a bit harder nearer the edges and softer as they move away

cant seem to hit that right

[dusty gyro]

there's a variable for that

[mild oxide]

messing with exponent and source angle for the directional

[dusty gyro]

light angle I think ?

yeah source angle

[mild oxide]

yeah light source angle

each build takes like one hour

hah

[dusty gyro]

not using GPU LM ?

[mild oxide]

dont think its availabke for 22.2

[dusty gyro]

it is

[mild oxide]

checked like 3 days ago

oh hella

imma get

[dusty gyro]

just force it through the bat launcher

minor engine revisions wont break it

you need the new dlls only for major engine revisions

[mild oxide]

is ee

alright ill get it

[honest temple]

Even with light and sky bounces on 25, and GI on 3.
There is still very dark behind the curtains and stuff...
Anyone have any tips to how to get more light in the room without using exposure?!

[dusty gyro]

@honest temple using RT or LM ?

[honest temple]

Standard raster

Lightmass

[dusty gyro]

aight

whats your HDRi like ?

if you use one

[honest temple]

will have a look at the lightUV's later

None atm!
Only default sky, and a backround

Maybe if will help to add a HDRI sky?!

[dusty gyro]

yeah absolutely

https://hdrihaven.com/

get your fill here

[honest temple]

will create a hdri sky later! 😄 NICE MAN tnx

really need some new HDRI's

[dusty gyro]

these are mostly very good quality HDRis

its my goto resource

[honest temple]

👍 👌 🤤 looks like good hdri quality yeah

[dusty gyro]

😉

[mild oxide]

cpu lm

gpu lm

cpu lm has like ~2k lightmaps on the visible objects

4k on the wall and floor

gpu has like 256/512

[dusty gyro]

build time ?

[mild oxide]

i didnt record it but felt similar

let me check the logs

[dusty gyro]

you must have one heck of a CPU and weak GPU then

[mild oxide]

i7 4790k

1050ti

should i tinker with the gpu lm settings?

i just put it on the insane mode

wanted to compare renders since the cpu one was maxed out too

[dusty gyro]

ah

well if its in insane no wonder it takes a lot of time

the 1050ti isnt a beast either

[forest depot]

pretty sure a 1050ti should still be 10x faster than the 4790k

in my experience a single 1080 was faster than 30 CPUs on swarm

[dusty gyro]

what are your lightmass settings @mild oxide ?

true

[forest depot]

if there isnt much else in that scene outside of the visible shot, that should take 1-5 minutes

[dusty gyro]

oh, do put in a lightmass importance volume too

[mild oxide]

scenes pretty empty but my lm settings are cranked up

and yeah

[forest depot]

how cranked?

[mild oxide]

ive got the imp volume in

wait

[dusty gyro]

I've had good enough results with 10 bounces on the skylight

yo

[mild oxide]

i tried 10

[dusty gyro]

100

[forest depot]

100 bounces!?

[mild oxide]

ya i tried 10

[dusty gyro]

dafuq

no wonder it takes ages

[mild oxide]

i didnt want to do this trust me

[dusty gyro]

0.1
10
10
10

is what I use

[forest depot]

thats exactly what i use lol

[dusty gyro]

and my bakes arent taking longer than an hour

[mild oxide]

yeah usually thats what i go for

[dusty gyro]

on full industrial/office/lodging buildings

[mild oxide]

no no

listen

ive tried

i didnt wanna do 100

i kept getting issues

[dusty gyro]

what issues ?

[mild oxide]

splotches

missing ao

[forest depot]

thats not the number of bounces

[mild oxide]

jagged shadows

[forest depot]

thats samples

[dusty gyro]

yup

going lower than insane will give you splotches and dots

lower bounces

[mild oxide]

oh

[dusty gyro]

will just give less light

because the light will bounce less

10 is the right value imo for archviz

[mild oxide]

usually what i use

this was an exception

[dusty gyro]

keep it on insane

be sure to bake in production

but lower that bounce count

[mild oxide]

any other tweaks?

[dusty gyro]

good UVs

dont go higher than 1024px

[mild oxide]

yeah obvs

ok

[dusty gyro]

that 1050ti wont be able to fit it in its VRAM

[mild oxide]

wait do uvs matter for the gpu lm too

[dusty gyro]

yep

although it gives better results regarding island leaks

[mild oxide]

i see

[dusty gyro]

compared to CPULM

[mild oxide]

hmm aight

[dusty gyro]

Prometheus is even better

but its not really ready

[mild oxide]

whats that

[dusty gyro]

@hallow arrow hey luoshuang ! Do you know if you're gonna keep working on Prometheus btw ?

experimental GPULM

with a different approach

[mild oxide]

ah

[dusty gyro]

but from what I understand luoshuang has shifted his ressources to lightmass 2.0

[mild oxide]

still gpu?

[dusty gyro]

will be both afaik

[mild oxide]

i see

[dusty gyro]

cpu legacy

[mild oxide]

wait is it being officially incoporated?

[dusty gyro]

yeah to some extent

[mild oxide]

niice

[dusty gyro]

luoshuang works for epic now

[mild oxide]

so do you

[forest depot]

i imagine hed be taking his learnings and applying to a new lightmass from scratch

[mild oxide]

i hear

[dusty gyro]

in a couple months I'll be yep

[mild oxide]

hella

[dusty gyro]

on Datasmith for AEC

[mild oxide]

congrats

[dusty gyro]

🙏

[mild oxide]

whats aec

[dusty gyro]

[mild oxide]

ah i see

[mild oxide]

pls

organics gives me ptsd

[dusty gyro]

haha

[mild oxide]

i barely passed

[dusty gyro]

so did I

[mild oxide]

now for those shadows

one more q

hold up

is the jagged shadow from the lightmap res?

[forest depot]

no

[mild oxide]

not on the book but the ones on the table

[forest depot]

its from geo being too close to another, its a flaw of current LM

[dusty gyro]

is that GPU or CPU ?

[forest depot]

thats pretty bold trying to do baked lighting on a feather haha

whats the UV on that like

[dusty gyro]

anyways yeah, current LM uses pixels to bounce the light right ?

[mild oxide]

this is gpu

[dusty gyro]

instead of rays

hence the jaggies

[mild oxide]

cpu one is fine

i see

[forest depot]

im not actually sure..

[dusty gyro]

I remember luoshuang talking about it a while ago on #graphics

[mild oxide]

wait ill send again for comparison

[forest depot]

i thought it was rays

[dusty gyro]

also

luoshuang brought us Virtual Textures in lightmaps

@dark oriole is bananas about it

[forest depot]

thats in 4.23?

[dusty gyro]

yeah

[forest depot]

so my understanding is.......

texture streaming will be amazing

but workflow doesnt change

[dusty gyro]

holy F

https://github.com/AlanIWBFT/GPULightmass

its open source now 😐

[forest depot]

yeah haha

[dusty gyro]

man

I missed so much stuff

[forest depot]

luoshang linked that to me when i tried to show him a bug

[dusty gyro]

haha

[mild oxide]

gpu

ik the cpu one is fixed with texel size

cpu

[dusty gyro]

have you unchecked compress lightmaps ?

[mild oxide]

ya

[dusty gyro]

GPULM shadow looks a lot softer

it might just be that

[mild oxide]

hmm i see

[forest depot]

yeah GPULM is not perfect

but the performance is just too good to pass up

for me its something like 30-50x faster

[dusty gyro]

its godly

[mild oxide]

yeah no ofc. i was just wondering if there was a fix for this

[forest depot]

not that i know of

[mild oxide]

i see

[dusty gyro]

went from not even thinking about using lightmaps on our projects to

use em everywhere

became even better since we have a Titan RTX

[forest depot]

and i went from using our company CPU renderfarm which is supposed to render vray projects

[mild oxide]

he;;a

[forest depot]

to baking on my own workstation faster

: D

[dusty gyro]

😄

[mild oxide]

i want a quadro rtx

D:

[dusty gyro]

eh

for unreal

[mild oxide]

raytracing

[dusty gyro]

if you do small scale archviz

dont need it really

get a titan or 2080ti

[forest depot]

i only have a 2080

[dusty gyro]

quadros are about driver stability for CAD softwares

and precision calculus

[forest depot]

the vram does help

[mild oxide]

ah

not just small scale though

do everything

[dusty gyro]

Titan RTX has the same amount of VRAM as the quadro 5000

or 6000

24gb

[mild oxide]

exteriors and all

[dusty gyro]

while costing twice less

[forest depot]

true

[dusty gyro]

https://i.imgur.com/WwLRkRd.png

this project (not pictured, big building on the left, bigger than these two) was baked in

I dunno

30/45mn ?

its got basic furniture in every room or so

[forest depot]

yeah its stupid fast

i cant wait for what is coming officially

itll be mental

[mild oxide]

sweet

[dusty gyro]

defo

@mild oxide https://i.imgur.com/ejOeaee.png

you had this kind of stuff right ?

on lower quality settings

[forest depot]

ive never seen that

[dusty gyro]

this is what it gives you sometimes

on low quality

[mild oxide]

cant say i have

[honest temple]

WOW! that is a diff between CPU and GPU render

[mild oxide]

looks like noise central out here lol

i gotta say tho i like the way gpu handled the gap between the wall and the floor

[honest temple]

@dusty gyro Have you adjusted the SUN soft shadow angle (or what its called)

[dusty gyro]

on what ?

[honest temple]

The sunb

[dusty gyro]

that last screen ?

[honest temple]

yeah, for the shadows

[dusty gyro]

ah

nah dont worry

it was just a bug

[honest temple]

ah hehe

nice lighting btw! 😃
Good to see it's not just me playing with that shitt hehehe

[mild oxide]

glitch in the matrix boyos

[honest temple]

@mild oxide Your interior lighting is really AWESOME!

[mild oxide]

hm?

oh thanks man

its gi tho

[honest temple]

Like the GI you use... Are you using Light propagation btw??

[mild oxide]

no

just a basic setup

sun, skylight with hdri

[dusty gyro]

HDRi + GPULM = godly results without too much tinkering

[mild oxide]

skysphere and a liv

[honest temple]

true

[mild oxide]

yeah i discovered hdri lights up waaay better way too late

hah

[honest temple]

I'm testing to get best results with GI and LVP.
I bump up the LVP to about 2 / 3... Then set the distance to max so there is not much bleeding

[dusty gyro]

dont use it too much

LVP is kinda dead now

[honest temple]

i know

But it still gives darker areas much more bouncing light from the sun... And takes with it the HUE from the surfaces it bounces from.
So that why i like it 😃

[dusty gyro]

true

you wont need that once RT will be optimized enough 😄

[mild oxide]

no rt in navi sadly

wouldnt that be something

rt but cheap

[honest temple]

Well, RT is what Arch-viz project need....
When i upgrade to RTX or at least GTX 1080TI.
It's bye bye Raster, and welcome RT 😄 hehehe

[dusty gyro]

well...

half raster half tracing 😄

[mild oxide]

@forest depot

[dusty gyro]

urk

[forest depot]

ummmmmmm

[mild oxide]

you wanted to see the uvs

[forest depot]

i did

im glad i asked though

[mild oxide]

its like rain

hah

[dusty gyro]

hang on I've got worse

https://imgur.com/UTMEz8U

marketplace asset

D:

[forest depot]

just wanted to see if you found a magic way

but there isnt

whats wrong with that

thats perfect

[mild oxide]

marvelous asset im betting

[dusty gyro]

prolly

[mild oxide]

curtain would be single rectangle lol

[dusty gyro]

moar UV horror

https://i.imgur.com/PA5pli3.png

https://i.imgur.com/xFisKeo.png

[mild oxide]

is this modern art

ive got a uv that makes my editor lag when i open it

so uh

[honest temple]

Woow

Thats heavy uv

[upper root]

Its beautiful....in the "how can you mess up this hard" sort of way, but still breathtaking nonetheless

I suppose if you're using substance painter or something you can sort of get away with this?

[mild oxide]

Just use triplanar ezpz hehe

[mild oxide]

@dusty gyro what software do you use for uvs

3ds?

[dusty gyro]

whats an UV ? @mild oxide 😄

nah I dont use any

models straight out of revit, use UE for lightmap unwrapping

and triplanar materials for textures

[mild oxide]

I see

Its what i do too but the material uvs are a mess

Almost always

[dusty gyro]

thats why triplanar > all

[mild oxide]

Ya of

[dusty gyro]

in some cases it looks a bit odd

but most of the time you're gucci

[mild oxide]

ya

Aight
