[mild oxide]

went a little overboard with the post

fix it tomorrow

and some missing materials

any tips?

[tall sluice]

sharper shadows, they seem to be floating a bit

[mild oxide]

intentional

id like them to be a bit sharper around the edges

but i want that area shadow effect

apparently its one or the other

but yeah ik wym with the chair legs

bugging me too

[tall sluice]

hmm, can you make the object shadows slightly lighter?

I think that could fix it

[mild oxide]

You mean the light intensity?

Hmm alrihht ill try that

[honest temple]

@mild oxide maybe less roughness on the lamp. And maybe just me, but there is maybe a little to much specular on the wood desk!? Just a tiny bit

[amber tendon]

Most of you guys use GPU Lightmass + custom HDRI via Skylight and then if appropriate a directionalLight, right?

[forest depot]

Yep :)

[mild oxide]

anyone ever get this error?

pops up right after a datasmith import

tried importing in a new project

still happens

tried re exporting the datasmith file

and apparently only an issue with this specific scene

other datasmiths work as intended

Hmm i suppose its time to do some copy pasting

Oh well

[amber tendon]

Cheers, Electric

Looks quite nice, agent

Sharp shadows have been mentioned but you pointed out that was intentional

[mild oxide]

Yaya

This my first serious work so

Sure I'll get better with practice

Possibly raytracing

Thanks 😊

[digital wasp]

I am trying to create the material preview UI for selecting the material for the flooe at runtime. do yo guys have any idea how to create something like having some material preview spheres in the scene which will have the "OptionMaterial" applied to them and "OptionMaterial" is the array varible which can be selected for each actor blueprint while creating the level

I tried creating the preview for each material if option materials are available at event begin play using the scene capture 2d and setting their target texture to the dynamically created render targets but those scene capture components are rendering all black

[solemn hawk]

You can apply the material to a sphere and have it on a separate lighting channel so it’s only affected by the lights you want

[pearl maple]

Can you point to any doc or tut on sperate light channel? Not sure how that works.

[amber tendon]

https://docs.unrealengine.com/en-US/Engine/Rendering/LightingAndShadows/LightingChannels/index.html

basically each object and each light has a lighting channel

you can mix and match between them

[pearl maple]

How would one go about creating replaceable models with baked lighting for VR exp.

For example I have one scenario where all lighting is baked now I have to give an option to show different kinds of models at the same place. Can this be done with baked lighting? maybe pre baked using this https://docs.unrealengine.com/en-US/Engine/Content/Tools/RenderToTextureTools/Setup/index.html

[dusty gyro]

you can try lighting scenarios

https://docs.unrealengine.com/en-US/Engine/Rendering/LightingAndShadows/PrecomputedLightingScenarios/index.html

[pearl maple]

But those are for complete scenes, I only have to change one model with the same lighting.

[mild oxide]

One model also constitutes a scene

[dusty gyro]

you cant edit your scene lightmap at runtime

so you can either :
1 - Use lighting scenarios (swap the whole level lightmap)
2 - Use dynamic lighting (wont look as good)
3- Use Distance Field dynamic lighting on objects you want to change (will look at tad better)

Yay, archviz concept modelling

Showcased on the Quest, pretty cool stuff

[amber tendon]

stairs+wall looking cool!

[dusty gyro]

thanks ! Another perspective

I'm doing it for a friend who's restoring a farm barn into a massive house

that wall is intended to be used as a library

[dusty gyro]

And a video recording of it, straight out of the Quest

[solemn hawk]

@dusty gyro that Lightmap res looks pretty good, I’ve had issues porting to mobile with high quality light maps in the past they always got compressed pretty terribly , what settings did you use?

[amber tendon]

What's people's view on motion sickness with instant-teleportation in VR?

Also I wonder about performance with UE4

[dusty gyro]

@solemn hawk my default archviz settings, ie somewhere between 128 and 1024 I guess

I can check tomorrow

I'm baking with GPULM at insane quality

[marsh dragon]

@amber tendon Ive had the vive for a year and a half now, and teleportation is like 5 times more disorienting than traditional movement

i don't know why people think teleportation is better, you loose spatial awareness by teleporting

[amber tendon]

@marsh dragon IMO the "dashing" is already much better

it works quite well

[marsh dragon]

dashing sucks too honeslty

best to give players complete freedom in movement

just good ol' classic movement, with no added weird mechanics like dashing and teleportation is best

[cyan ether]

doesnt that cause nausea

[dusty gyro]

I really like Teleportation for that exact reason

every other movement (dash is a bit of a mix between solutions) brings up dissonance between the brain and the body (acceleration mostly)

[cyan ether]

im hoping 170+ hz is the key to solving all nausea

but im not sure if thats the root cause

[dusty gyro]

some way to negate internal ear problems would be the solution

stuff like micro impulsions in the internal ear to simulate movement

[marsh dragon]

Nah you really do get use to standard movement, you overcome any motion sickness fairly quickly

I cant even imagine pavlov or onward being fun with teleportation

[mild oxide]

@dusty gyro not unreal related but look at this madlad https://www.youtube.com/watch?v=oFzt-3sRExI

https://www.youtube.com/watch?v=JBP3uUkpNPs and a bts

19 days to render

[dusty gyro]

Damn

[mild oxide]

insane work tho

[dusty gyro]

damn

that tracking work to apply in the render

sweet stuff

[mild oxide]

yeah thats some interesting stuff

wanna try fstorm now

https://blogs.unity3d.com/2019/06/05/unity-reflect-bim-to-real-time-3d-in-one-click-for-better-design-decisions/

[mild oxide]

That one click language makes me think of enscape

Still think it's a scam

Also this is pretty cool

[dusty gyro]

haha yeah you will never get good results in one click

being able to live link at runtime is sweet tho

[mild oxide]

Yeah exactly

I wish ds did that

Time to learn unity ig

[dusty gyro]

gonna try to push live linking at epic once I'm there

but it comes with a lot of drawbacks imo

[mild oxide]

Hell ye

Oh

Like?

[dusty gyro]

well for once you need to make a massive database

if you want your materials, props and the likes to be replaced correctly

https://unity.com/aec/reflect

you cant optimize like you'd want since its all automatized

[mild oxide]

Oh yeah fair

[dusty gyro]

ie some assets might not be converted correctly and look like crap at runtime

[mild oxide]

Ig that's what the ds guys be working around now

[dusty gyro]

its good to see game engines work to make the simplest UX possible for architects tho

[mild oxide]

They gotta be looking at livelink at least

Yeah true but the unreal ui is kinda ass

[dusty gyro]

really ?

[mild oxide]

But then I saw zbrush

[dusty gyro]

I use Unity for VRChat

and damn I forgot Unity had this weak, small UI

with buttons that wont work unless you have the precision of a cyborg

[mild oxide]

Lmao

That's true they do have small buttons

Used to Unreal though

Those are kinda big

I like houdini and c4d ui

C4d primarily

Sweetspot between ease and functionality

Ig it's all subjective

[dusty gyro]

yeah

[mild oxide]

Lmao so i got this new game today

Yesterday*

And i just kept looking at the textures

"hmm nice walls"

[dusty gyro]

yep

working in the game industry and archviz

you're walking in the street

"damn thats a nice wall/puddle/reflection"

colleagues be like "wtf bruh"

happens all the time 😬

[mild oxide]

Hah

😭

I just wanna enjoy my games

I was working on this project once and got kinda into it. Came up after a few hours and saw some real life. First thought that pops into my head is hmm thats hella photoreal

Then i realised its just real

Lmao

[pearl maple]

anyone using vray for Unreal here? How do you think it compares to the default unreal path tracer?

[solemn hawk]

It’ll give you a better result than the unreal path tracer, because the ue4 path tracer isn’t setup to give final images yet

[mild oxide]

Mm its p good

V beta tho

[solemn hawk]

Last time I tried it it crashed on almost everyone of my scenes, has it gotten better?

[mild oxide]

Yeah the new one works

Fucks up materials sometimes but overall pretty good

[solemn hawk]

Have you tested it on large scenes?

[mild oxide]

Medium sized scenes

A house

[mystic lynx]

wtf @dusty gyro oculus quest is that smooth?

[dusty gyro]

Yeah @mystic lynx

Running at 72hz capped in both the tests I did

The new mesh renderer does wonders

[forest depot]

havnt had any success with vray for unreal

[hallow arrow]

meanwhile has anybody tried to use vray bake? how is it compared to my GPULightmass?

[forest depot]

same story for me, i think i need to spend more time with vray

pretty hard to beat gpulm atm

vray didnt work straight out of the box, which is a problem

compared to GPUlm you just swap it over and it just works

[dusk pelican]

I don't see any gpu option

[mild oxide]

It's wizardry

[sharp vessel]

hi guys! any tips on how to apply a "override material" to all the objects in the scene so I can adjust the lighting faster and more efficiently?

[mild oxide]

Change mode to lighting only (or detail lighting if you want reflections)

@sharp vessel

Its in the top left of your editor window

[sharp vessel]

oh its just that my light building is taking forever, even after I applied a clay material to all the objects, and set quality to preview

any tips on how to do fast drafts for lighting?

[mild oxide]

Set build quality to low or medium

And use gpu lightmass

[sharp vessel]

Thanks mate! I´m just downloading it and will do some tests later

[mild oxide]

Nw :D

[sharp vessel]

any documents related to how to set it up inside the UE editor?

or how do I confirm that it is using the gpu?

[mild oxide]

It's on the forums. Use the bat file installer

[tulip whale]

Hello there.
Not sure if this is the right place to ask but let me know if i should put this somewhere else. So, I'm working on a Third person perspective shooter project and I'm facing an issue of "Screen Tearing".

On "Full Screen Mode", Tearing is quite easily noticeable which is making this feel way weird.

On "Windowed Borderless Mode", Tearing is minimal but then the mouse sensitivity starts behaving awkwardly while aiming.

So here is the question - "Is there anyway to reduce screen tearing without using V-Sync?".

Here is my system configuration :-

Processor - i7-4770K
GPU - Nvidia GTX 1070
RAM - 16 GB
Monitor Refresh Rate - 60 Hz

Unreal Editor version is use - 4.22.2

[zinc siren]

Hi all, I'm having a strange issue with light build on large surfaces not generating full shadows. Right side is a scale of 1 with a 2048 res lightmap, left side is same geometry with scale .5 and with a 128 lightmap. I want to make it look like the left but with a scale of 1, and I cannot figure out why this is happening 😭

[brisk jewel]

@forest depot GPULM? is that the GPU based lightmass I've heard so much aboot?

@zinc siren presumably it's your lightmap size, I'm guessing at .5 scale a lightmap of 128 is equal to 256? however I have no idea if that's right, lightmaps might be affected by scale?

[zinc siren]

The lightmap for the surface that wasn’t working was 2048. But I didn’t realize my scene lighting scale was at 1. Brought it down and now it’s working

[forest depot]

Yes it is

[cyan ether]

whenwhenwhenwhen

[dusty gyro]

soon™

[cyan ether]

i hope for one day an xref equivalent for uassets, some of my assets could do with being pooled from a central location across projects

[forest depot]

Do you have the inside scoop now @dusty gyro

:D

[dusty gyro]

Nah

[brisk jewel]

am I right in thinking that the gpu lightmass only works on binary versions of the installation?

[mild oxide]

No

[brisk jewel]

oh lovely! so is there an installer for the launcher version? sorry I was looking at the forum post about it and not quite sure what to follow.

[mild oxide]

Yes there's a bat file. Should be mentioned in the forum post

[worthy loom]

hi, what is the best setting for glass in archviz. i have the advance glass pack on the marketplace. but when every i use it , it has very weird reflect like this,

i try to set fresnel falloff highest as i can, but seem like the effect stuck at 10.

i heard it has something to do with how UE4 caculator reflection and opacity ?

[dusty gyro]

@worthy loom most of the time I just use a very low reflexion/ioR value

[brisk jewel]

Hey all. I've just started using GPU lightmass, it's super fast but my scene looks very different from the old bakes, reflections seems much harsher

I did have two sided materials and emissives acting as static lights but I've turned them off now, they shouldn't have been doing much to the lighting anyway but any general pointers?

[lethal vigil]

https://www.youtube.com/watch?v=Jt2VEKlovs4

tested distance field indirect shadow on dynamic objects with raytraced reflection.

[dusty gyro]

:rubs hands: nice another video :)

some good stuff in here, new template refactor, HDRi backdrop actor

workflow improvements

lots of performance refactors too

[mild oxide]

hdri finally???

[dusty gyro]

yeah

I mean it was already doable

but you had to make your own actor and all

[mild oxide]

Yeah but it always feels like a workaround

Yeah

[dusty gyro]

New HDRI Backdrop Actor:
With the new HDRI Backdrop Actor, it’s faster and easier to create a realistic background and lighting environment for your Level from a single HDRI image
Simply drop the Actor into your Level and assign it the HDRI texture you want. You’ll get your texture projected onto a backdrop, a Sky Light automatically set up to provide ambient light drawn from the texture, and a floor surface that captures the shadows from your Level

sounds a lot easier

[mild oxide]

Yeee

Bless em

[dusty gyro]

😃

[mild oxide]

Did u do this

Bleas you

[dusty gyro]

I did not 😄

going to CAN end of the month

[mild oxide]

Bleas

Hella

Oh btw i wanted to ask

Wait ill dm

[dusty gyro]

sure thing

[lethal vigil]

hi guys just first try 4.23.0 p1

i think hdribackdrop must have brightness and contrast settings for hdr. The desired lighting mode seems difficult to capture without these settings.(compared with 4.22.3 level)

https://www.youtube.com/watch?v=kCxN1uGIBiI&feature=youtu.be

[cyan ether]

oh wow new preview
are you sertac @lethal vigil ?
absolute beast if yes

[dusty gyro]

yeah he is @cyan ether

[hallow arrow]

has anyone here tested 4.23 lightmass?

just want to know if my dark corner tricks & lightmap padding fixes have caused unexpected problems

[dusty gyro]

@hallow arrow I can give it a go what kind of mesh shape do I need to use ?

[hallow arrow]

you can use any

[dusty gyro]

will take a couple assets from packs then

[hallow arrow]

for lightmap padding fixes, there are some additional steps to activate them as we don't want to break existing lighting builds

1. select all the mesh assets you'd like to apply the fix (the meshes should have 'auto generate lightmap uvs' checked as this fix is for that)
2. bulk edit with property matrix
3. change 'lightmap resolution' to any value. this step will freeze the editor for a while as the lightmap uvs of all the selected meshes will be regenerated
4. press ctrl+z to revert the resolution number change. now the fix is applied.

[dusty gyro]

aight

bulk edit lightmap rez

brings back some bad memories of pre datasmith 😂

[hallow arrow]

or you can also reimport all the meshes you want to fix 😅

[dusty gyro]

nah I'll just user the matrix

woopsie

crashed @hallow arrow

while trying to use the edit property matrix on one asset

Assertion failed: SerializeNum >= 0 [File:D:\Build\++UE4\Sync\Engine\Source\Runtime\Core\Public\Containers/Array.h] [Line: 1082]

lots of MeshDescription and MeshBuilder references in the crash report

does editing in the mesh editor directly apply your fix for padding ?

holy hecc

getting loads of crashes just by opening the mesh editor/changing stuff in it

same error

[hallow arrow]

🤔 looks like our mesh editing code is bugged

[dusty gyro]

yeah

[hallow arrow]

does editing in the mesh editor directly apply your fix for padding ?
yes, so you can just try it on one mesh

and observe if the generated lightmap uvs has shifted a lil

[dusty gyro]

do you have access to the logs with client ids ?

I can PM you my IDs if you want to check the crash reports

before fix

[hallow arrow]

yes

[dusty gyro]

after fix (new res at 256 instead of 64)

hasnt changed a bit

(I did press apply changes)

[hallow arrow]

not that resolution

the one in the bottom

[dusty gyro]

oh the other one

[hallow arrow]

when you change the number the lightmap uv will be permanently modified

even if you change it back

[dusty gyro]

doesnt change anything

[hallow arrow]

this mesh wasnt using generated lightmap uvs 😃

[dusty gyro]

oh

right

[hallow arrow]

all newly generated lightmap uvs will use the new fixed algorithm

[dusty gyro]

another mesh

https://i.imgur.com/b4wTZ47.png

before

after

[hallow arrow]

so this one was using generated lightmap uvs?

[dusty gyro]

nope

I'll import some datasmith asset

should have generate lm uvs from the get go

[hallow arrow]

basically it will fix the dark corner problem that this guy was raging about 😄

[dusty gyro]

😄

[hallow arrow]

the problem was, our documentation was also bugged

so even if you follow it precisely, you're still going to get dark corners which is very frustrating

[dusty gyro]

yeah I bet

right so

ah wait a sec

if I import it with datasmith

[hallow arrow]

it is now fixed after i talked to them

[dusty gyro]

will it have the padding fix already ?

[hallow arrow]

yes, all newly imported meshes are generated using the fixed algo

[dusty gyro]

alright

dang need to do a 4.22 project and migrate it then

[hallow arrow]

for all existing content, you need to apply the bulk editing trick

[dusty gyro]

yeah

[cyan ether]

nice, seems this new hdribackdrop was modelled on vray's

[forest depot]

By any chance would the lm fix also be applied to gpulm

[hallow arrow]

@forest depot have you tested it ? does the lm fix indeed look better?

it is actually a reduced form of a new technique in the Prometheus fork of GPULightmass (which is frozen now): https://forums.unrealengine.com/development-discussion/rendering/1460002-luoshuang-s-gpulightmass?p=1595479#post1595479

[forest depot]

Nah haven't had the time yet :(

Super keen to try tho

[mild oxide]

@lethal vigil i was following your rtx setup tutorial

And i can't find the new dof algo in the project settings

They removed it or something?

Oh nvm its still available in 4.22

[frail bluff]

Is it good to use modular house sets for Archviz?

Wondering and analyzing for next project - I'm considering the benefit for optimization and the same scale for textures

[mild oxide]

You mean from the ue4 store?

Not really unless youre using them for far off/low lod purposes

Theyre optimized for games but most of them dont fit well in photorealistic settings

[frail bluff]

So how do you deal with the same texture size for each wall?

Let’s say we have a conocerte texture and we want to have the same size of it and our walls have different sizes. Good uv maps preparation for the same size?

@mild oxide I mean modular set of a house that you prepare in dcc before exporting to UE

[mild oxide]

Id say yeah just resize the uvs if thats the way you want to go. Or a procedural material from substance designer

Resizing uvs might be bad for your texture though

Also do you mean like a kitbash? That should be good yeah

[frail bluff]

Ok thanks @mild oxide

[mild oxide]

:D

[pearl maple]

@frail bluff You could also use world space UV's for static meshes.

[livid harness]

Do you guys use datasmith a lot?

[mild oxide]

Yup

[livid harness]

Are you using it from Revit and if so, how good is unreal at determine materials and mesh UVs

[mild oxide]

3ds

I believe life for life uses itbwith revit

From what ive seen though its pretty good with a basic setup regarding materials. But you always have to optimize/tweak them for realism

But it gives you a good starting point

And uvs is just enhhh. Generates good lightmap uvs. But the 0 channel it messes up 3 quarters of the time

For me anyway

[dusty gyro]

@livid harness Revit for datasmith will translate meshes, material IDs and texture UVs well

you definetly dont want to use Revit materials in your end product tho

there's tools available to swap materials corresponding to a string for example

.ie "replace original materials with 'glass' by this material I made within UE4"

the great thing is that once your equivalence tables or string lists are done, you can reuse the scripts for all your projects (granted you use the same material names in revit between projects)

[livid harness]

tools for revit or ue4?

[dusty gyro]

within UE4

Datasmith just has an exporter for Revit

[livid harness]

Yeah Im currently developing a plugin for UE4 that does exactly that but it can also replace static mesh actors

because some of our prop models in Revit are not the best looking models

[dusty gyro]

thats already doable in UE4 tbh (with the dataprep tools)

hehe yeah I see

[livid harness]

I remember in the ue4 stream showcasing revit and datasmith the presenter was using a python script to replace the revit materials with substance materials

[dusty gyro]

https://docs.unrealengine.com/en-US/BlueprintAPI/EditorScripting/DataPrep/index.html

[livid harness]

ah its blueprints

[dusty gyro]

either BPs

[livid harness]

that is very interesting

[dusty gyro]

or you can use Python

[livid harness]

yeah we are still getting used to ue4 and they haven't touched blueprints too much so they wanted me to just develop and easy to use tool that has the same functionality in only a couple clicks

hopefully I can showcase it here once its done since I think lots of people can benefit from it

but thanks for showing me that i didn't know it existed until now

[dusty gyro]

the dataprep tool is still in its infancy

but you can still do some pretty good preparation of your meshes

I used it a lot to generate LODs (to save performance), swap materials, adjust lightmap resolution

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

[livid harness]

[amber tendon]

Do people actually use the ambient occlusion from Lightmass? Or is it usually left disabled?

[dusty gyro]

Depends how you like your lights baked

sometimes it looks better with AO, sometimes good baked GI is enough

[amber tendon]

fair

[jovial coral]

how do I improve the quality of shadows on a moveable object?

[dusty gyro]

by adding more cascades in your casting light

or switching to raytracing

[jovial coral]

how do I add more cascades? does the light need to be stationary?

[inland viper]

Was wondering if anyone uses the manual exposure settings with real world lighting intensity values or do most use EV?

[jovial coral]

I use manual exposure settings

[inland viper]

Hi Chris do you have a workflow in 4.22+ for calculating intensity of directional light and skylight intensity? Ideally I would like a solid realistic result as a base and tweak from there .

here is the option to increase dynamic shadow cascades found by clicking on the light and searching in the details panel. I think it is scene wide though so quite expensive

[jovial coral]

@inland viper the workflow I use is generally: Add skylight using either a grey cubemap or HDRI map. I do a lightbuild and make sure that the global illumination is good enough, if its dark I increase the skylight intensity. Then Ill add a directional light, and do the same thing. I will then use a post process volume to control burn, contrast and color etc to get the right final look

[mild oxide]

Use the path tracer to get an idea of accurate lighting

[jovial coral]

Agent, thats an new RTX feature?

[mild oxide]

Yeah

[vernal pecan]

Gathering some feedback from Unreal Studio users : who here is using the HDRi Backdrop introduced in 4.23 preview ?

[vernal pecan]

@mild oxide have you used it yet ?

[mild oxide]

@vernal pecan yeah i have

Imo could use more controls

[forest depot]

Has anyone tried octane for unreal... It just came out

My mind is blown

[mild oxide]

Wait wait wait wait what

Well i know what im doing today

[forest depot]

Yeah I just paused in the middle of the day to play with it for a bit haha

[mild oxide]

Is it on the octane site or marketplace?

[forest depot]

Octane site

It's like the pathtracer... But better cause it doesn't use rtx

[mild oxide]

Oh rip i dont have a sub

[forest depot]

🏃

It's free

[mild oxide]

Nvm the rip then

😋

Time to have fun

Pretty sad that thats my definition of fun

[forest depot]

I'm the same haha

Went holy shit! And had the whole office crowd around for a bit

[mild oxide]

🤣

Understandable

[hallow arrow]

can it bake lightmaps?

[forest depot]

Looks like there's a baking camera

[mild oxide]

@forest depot dude this is way more refined than the vray plugin

Like

Waaaaaaay

Fucking love it

[forest depot]

Yeah its the real deal

[mild oxide]

You made anything yet?

Love how it just translates unreal mats

[forest depot]

Nah just played around with it

I'll probably just implement it as a small part of my next real project as freebies

It's not exactly stable atm

Tried to activate it on 2 live projects but it crashed

Worked fine when I just migrated a whole bunch of assets to a test project tho

[mild oxide]

Yeah i just tried it on an evermotion project

Works like a charm

[forest depot]

hm i wonder what is in my actual projects that are causing it to crash

it gets through most of the assets when activating, just not all of them

[mild oxide]

@forest depot it crashed when i used substance mats

[forest depot]

ah right

i could try disable them

[mild oxide]

Yeah works without them

Should work with megascans too bc those use unreal materials

[mild oxide]

@forest depot

not too bad considering those are the starter content materials

[solemn hawk]

Substance need to add a way to bake their texture maps directly to unreal

[mild oxide]

they already do that

its just controlled by the substance factory instance

you could take the textures and put them in your own material

never really needed to before this tbh

[solemn hawk]

Well they’re not true texture maps though, vray for unreal has the same issue that octane has

[forest depot]

haha i just opened the same scene

[mild oxide]

Hah

AI48_07

[vernal pecan]

@hallow arrow I might be coming to visit you earlier than I anticipated 😄

[lethal vigil]

https://youtu.be/JZJ6Cc3h1XE

hi guys just fast comparison. seems like material coversion fail on translucent shaders.( or i cant figure it out) and light intesity really different.

[forest depot]

can always trust you to be using the latest thing released 😉

yeah im having trouble also trying to get glass to work properly

[mild oxide]

In octane?

[forest depot]

yeah

it definitely refracts

but it looks foggy

[mild oxide]

Ah i didnt pay much attention to glass. Could be a beta bug

[vernal pecan]

Awesome @lethal vigil !

[honest temple]

@lethal vigil I have also issues with getting translucent materials, or reflective surfaces to show in PathTracing view..

Perhaps the path tracing is just not including this traces, or just don't visualize the results back in the view?!

[mild oxide]

Anyone use cgaxis/poliigon textures?

The poliigon normal maps need to have their normals flipped right

Is it the same for cgaxis?

[gilded pulsar]

Hey all, I am trying to convert this entire shop that I have made in 3ds max a few months back. It contains 68 spots - when I import it to Unreal, all spots are pointlights, then I replace them with spotlights, but they all point the wrong direction. If I rotate them all in local mode it is only local for one spot I seem to be missing something here. In 3ds max when I rotate many objects at once I use local axis combined with "use pivot point center" is there anything like this in Unreal, or is it even the solution?

[frail bluff]

@mild oxide the best option is just previewing - if sth looks odd - just invert and done : )

Guys, I'm having problem with custom tree export form blender to UE. I use mTree add-on and I created the whole tree. Now i want to join the leaves (they're instanced) and when I do that I have 16x more vertices. Anyone knows how can I properly export my tree?

Before joining/merging in Blender:

After merging (huge vert number)

[vernal pecan]

@gilded pulsar which max revision are you using and datasmith for max plugin versions ?

[gilded pulsar]

Max 2017 and newest datasmith

[worthy loom]

Hi veryone, can you help me out
how to make good subsurface light for object
every thing is fine with simple lantern or table lamp
but when it come to complex mesh like animal, the subsurface light look so bad in side view.

because of its bad look i had to move the light outside of the mesh, its good for 1 camera view. but not for multi

[vernal pecan]

@gilded pulsar do you have a datasmith revision number ?

when you install the plugin there's a rev number on the bottom left

if you can send me the file with just the lights that would be great too

[harsh oyster]

Hi, how to optimize VR rendering performance if I have a lot of video on the walls in my game ?

[gilded pulsar]

@vernal pecan Well now I have it installed and cant remember the number. But it says it supports Max 2016-2020 and engine version 4.19 to 4.23 and I have 4.22.3 installed.

@vernal pecan It is as if I can turn them all 90 degrees they line very well up to the original scene. But I cant seem to be able to do it to all of them at once. And In in scene I got 68 spots, in others I got a few hundred. So it could become alot of work.

[brisk jewel]

Hey all,

I've been toying around with Vray for Unreal, but there's part of me wondering if the lightbake method is rather pointless... Can't I just do that in 3Ds Max and render all the (presumably) Total Lighting passes there and use them in Unreal later?

We use non linear workflow and all our materials don't import because of plugin use, so the whole thing feels a bit superfilous to me.

superfluous*

[forest depot]

you cant import lightmaps afaik

or rather, you can import the textures but theres no way to apply them

[brisk jewel]

well I can import them as textures and apply them in the material.

have the material as unlit but reflections should still work and all

[forest depot]

would be very interested in seeing how it looks

[brisk jewel]

I was happy with the normal Unreal lightbaking but work is consumed with Vray thinking it's one click solution

[forest depot]

ah

[brisk jewel]

just sat here with two Vray for Unreal licenses, slowly baking away or a farm of 60 vray for Max licenses...

[brisk jewel]

in fact, has anybody used Vray for Unreal?

[forest depot]

i tried it for a few minutes and gave up

octane for unreal seemed way less temperamental

[brisk jewel]

heard great things about Octane but always been using Vray and a little Corona, love the idea of Redshift but outside of Unreal

general archvis question, should it take hours to do quick draft lightbuilds?

in a rather detailed lobby sized scene

[forest depot]

no

my draft lightbuilds take 5-10 minutes

but thats gpulm

octane doesnt bake

[mild oxide]

Yeah my work is also obsessed with vray

I can never get it to work right

Octane hella gucci

[brisk jewel]

I was using GPULM, got a 2080 here but was still taking a long time.

we do have a lot of lights in the scene and some lightmaps are 1024

but it is very slow still. We must be messing up right at the start

@mild oxide if only they'd look at other render engines but it's a VRay cult here, old hands and set in their ways, but obviously i'm doing things wrong too

[mild oxide]

Thankfully mine look at other engines. I showed them the octane render and they seem agreeable to buy me a sub

[brisk jewel]

my work place wants their Vray quality renders right in Unreal but they don't use linear workflow and 3rd party plugins like color correct and multitexture so nothing imports over

[mild oxide]

And good thing is it should work fine with datasmith translated vray mats

Yeah color correct is a bitch

Did you watch the latest webinar of vray for unreal?

Shows u a workaround

[forest depot]

most people here use vray

but it makes sense for traditional archviz

@brisk jewel i also us a 2080 annd dont shy away from 2k lightmaps at all

use*

how many 1k lightmaps are we talking?

[brisk jewel]

Not that many. About 10 or so at most?

some stuff tends to be high poly but I don't see that affecting the actual rendering

[forest depot]

yeah something is wrong

i can have easily 20+ 1k and 10 more 2k maps

and itll be fine

[brisk jewel]

and render fast for draft?

[forest depot]

i mean for gpulm

its still production quality

[brisk jewel]

think I'm stuck with VRay anyway, the company demands it

[forest depot]

ouch

is it a big company?

[brisk jewel]

yeah (Visualisation One) about 25 people

don't quite understand their obsession really, I did good scenes with the same old Unreal lightmass

also I just realised I was baking with high settings so that explains something

[forest depot]

high in engine?

[brisk jewel]

yeah, the vray lightbake has quality settings I'd set to high this morning without thinking

[forest depot]

ah right

i actually have no concept of how long vray bakes take

i just use gpulm

[brisk jewel]

2k atlass was rendering in 5 mins on draft, and 60mins on high...

I was having fun with GPULM

[mild oxide]

I think i follow u guys on ig lol

[brisk jewel]

IG?

[mild oxide]

Instagram

[brisk jewel]

ah, yeah we finally got one of those.

I don't do the nice scenes, I do the models

[mild oxide]

Part of the nice scenes

[brisk jewel]

for I am a lowly modeller and all the visualisers can't model

[forest depot]

ah right

not a fan of visualisers who cant model

[brisk jewel]

likewise man, and I'm stupid enough to sit here doing it getting paid about 4/6k less

but TBH I don't really like arch vis rendering, I like all the things around it ut not pressing F9 to render

[mild oxide]

If you don't mind me asking, how much is the median salary for archviz jobs there?

Like how much can one expect to make

[brisk jewel]

you start at 18K, get to around 22 when you start visualising and can make near 30K and then 35K if you are a senior and lucky

[forest depot]

is this gbp?

[brisk jewel]

GBP

V1 is in the north west though, not London prices

[mild oxide]

Is that good? Compared to thr cost of living and stuff

[forest depot]

whats the cost of living compared to london?

[brisk jewel]

I can own and run a house alone on 24K and I do make bonuses(total was 28K last year

[forest depot]

its a bit low compared to auckland

[brisk jewel]

3 bedroom semi detatched around 130K

[forest depot]

but cost of living in auckland is insane

to buy?

[brisk jewel]

I have a friend in DNeg NZ who is on 85K NZD and he's still in a tiny place

yeah to buy, it's not a great area but I can walk/cycle to work.

[forest depot]

that 3 bedroom would run you 500kgbp lol

in auckland

[mild oxide]

Wtf

[brisk jewel]

it's just the whole National Average is 25K or so and you get a bit bitter seeing people make so much when they need you to do really simple poly work

[mild oxide]

Yeah thats understandable

Job markets never been fair though

[brisk jewel]

but I also get it, any kid can model in their bedroom, we have two freelancers in Bulgaria that make 500USD a week modelling for us

on and off.

[mild oxide]

But ig if you can own a house thats still pretty good

Decent savings?

[brisk jewel]

yeah I don't think I know how lucky I am

I have cash but I am a tight arse

[mild oxide]

Best way to save lol

[forest depot]

auckland is pretty fucked for home owning

[mild oxide]

500k gbp

[forest depot]

median home is 9x higher than median salary

[mild oxide]

Id say

[brisk jewel]

need that bubble to burst

[forest depot]

i bit the bullet 3 years ago

so not really keen on that

haha

[mild oxide]

What does that mean

[brisk jewel]

yeah, sad to think the best you can get in life these days is a house lol

[forest depot]

bought 3 years ago

[mild oxide]

Bit the bullet

Oh ok

That's a good thing though right

Property is always a solid investment

Or so i hear

[forest depot]

for very long term yeah

[brisk jewel]

yeah it is, it'd just be nice to also be like... well off 😛

[forest depot]

haha

the dream

[mild oxide]

Still a faraway dream for me

[brisk jewel]

Arch Vis, All the architechture and none of the architech money

TBH I have been tempted to mode to Bulgaria, open up a modelling company or just myself and buy the country slowly

[mild oxide]

Architecture has money??? Ok maybe i should switch back

Design field is in the shiiter here

Any creative job and you get paid peanuts

[brisk jewel]

as in an architect has money

[mild oxide]

Oh yeah ok

Uk is good for architects

Tough to get a job though

[brisk jewel]

Brexit is looming remember

[mild oxide]

Truee

What happens to intl students

[brisk jewel]

well TBH if you can do a mean ass Unreal scene and other things then I think V1 would be stupid not to look at your portfolio as we really need someone who knows what they're doing in UE4 and we've got so many high end luxury jobs to work on

[forest depot]

i need to check out your guys portfolio

[brisk jewel]

please do, we do great work but nooooo linear workflow if that's your thing and you have to work to the companys style

[forest depot]

thats real strange...

wait your guys website is your IG?

is there a way to just see the unreal stuff?

[brisk jewel]

nah we don't have any Unreal up yet

clients are real interested in the virtual camera ipad thing, and have VR

hate vr*

[forest depot]

ah

so youre working on it but it aint public?

[brisk jewel]

yeah

a lot of what we do isn't public, must be some contract things

[forest depot]

i see

[mild oxide]

Its the same here

[forest depot]

our stuff 90% of the time goes public very quickly

[mild oxide]

Lots of old projects up on the website

[forest depot]

as we're rushing for our clients so they can get to the market

[mild oxide]

New ones just go into permanent backup

[brisk jewel]

yeah, things are so old on our public here that one of few images I did 9 years ago is still online

[forest depot]

oh damn

ours are on a much tighter rotation

[mild oxide]

Noice

[forest depot]

actually ill share one that just went live today

[mild oxide]

Do

[forest depot]

https://www.developwise.com.au/sanctuary/

we just finished it today and the website went live

its the clients website but all the content is ours

[brisk jewel]

that's some mad turn around

[forest depot]

its the largest unreal project we've done

[brisk jewel]

that on the website is it?

[forest depot]

?

[brisk jewel]

oh the video is unreal

[forest depot]

yeah

99% of hte content is unreal

[brisk jewel]

do you rely on unreal generating lightmaps?

[forest depot]

yep

[brisk jewel]

lol fuckin' Technogym

[forest depot]

but yeah the project isnt just for using unreal to spam video and stills content, we also setup 2 PCs that run the project with our product

yeah...

[mild oxide]

Hella nice

[forest depot]

i made gym assets then was told

you have to use these exact models from technogym

ahahah

[mild oxide]

Riperoni

[brisk jewel]

tbh I've had enough of doing Gym assets

I'm either not as good as I thought or just really hate it now

[forest depot]

thats weird its my first time haha

ive actually never done a gym at all in archviz before

[brisk jewel]

how long you been in the industry?

[forest depot]

also.. never heard of technogym before this project

3.5 years for archviz

9 years for 3d

[brisk jewel]

they're just everywhere because they have an "okay" model library

ah so same as me just 9 solid years in this shit

[forest depot]

ah right

wouldnt have used them if i wasnt forced to use exact gym models >_>

[brisk jewel]

quite lucky here, for a long time we have done the models the client wants and had the freedom to model them but now with 3D Sky my talents are worthless

[forest depot]

😦

yeah i was a bit surprised hwen you said you were a modeller, we dont have specific roles like that here

[brisk jewel]

scary really, not 9 years and my job is not so important, should have been a compositor

[forest depot]

and its pretty much the same size

20 people

[brisk jewel]

yeah we did have a bigger modelling team but they were told they'd not get paid more than 18K so they've all jumped to visualising and I'm letf here managing the shit storm

[forest depot]

ouch

[mild oxide]

Yikes

[brisk jewel]

tbh I should have been visualising years ago, I can do so much, camera tracking, compositing, etc but don't get to do it as a modeller

[forest depot]

i had a pretty different path

started 3d as a lighting artist at an animation studio

then worked on games

then archviz

[brisk jewel]

wouldn't they have paid well? I've been tempted by games

[forest depot]

it was ok

but both the animation studio and games studio was the largest in auckland at the time

150 people

the animation studio closed down

so i went to games

then that closed

and i was 25... so i was like fuck the entertainment industry

[mild oxide]

I'm still not 25

D:

[forest depot]

you got plenty of time : D

[mild oxide]

Yeah plenty of time to grind you mean 😔

[dusty gyro]

@gilded pulsar will try on my end with your file and report back on the problem as soon as I can today, thanks a lot !

[brisk jewel]

31 here

[mild oxide]

Ok i think my max crashed

Again

Just end me

And 24 here

[brisk jewel]

you on Max 2018?

[mild oxide]

2019

But theres soooo many plugins

Sooooooooooooo many

[brisk jewel]

yeah I have 2018 at home and that fucker crashes if I change edit poly too fast.

[mild oxide]

Hah 🤣

[vernal pecan]

@gilded pulsar getting these warnings on export btw

[gilded pulsar]

@vernal pecan Does Unreal not support VrayIES?

[vernal pecan]

hmm thats a very good question

I can check that with the team as soon as they arrive

[gilded pulsar]

Great

[vernal pecan]

there may have been an unwanted regression at some point

I cant get the lights in unreal on my end somehow

just the meshes and the target dummies

[gilded pulsar]

I get the lights in but they import as pointlightcomponent so i replace them with target spots

[vernal pecan]

alright

[vernal pecan]

yep thats intended

since they use IES profiles

[gilded pulsar]

ok

[vernal pecan]

you definetly can change em to spotlights tho

in fact this will give you a better quality on light bakes

[gilded pulsar]

I do that but as said, they point in the wrong direction

[vernal pecan]

can you send me a zipped project with that scene ?

[gilded pulsar]

sec

[vernal pecan]

I might need some plugin to get the lights working on my end

all I get in max are "Luminaires" instead of light entities

uh yeah I do need Vray 🤦

[gilded pulsar]

cant send you that 😃

[vernal pecan]

haha yeah I'm installing it right now

alright now I have the spots in max

Alright so good news @gilded pulsar

I'm getting what I imagine is a good export on my end ?

[gilded pulsar]

yes

cant see if they point in the right direction

[vernal pecan]

they do point to their respective targets

[gilded pulsar]

you get PointLightComponent at first right and then you replace them with spotlight right?

[vernal pecan]

yep

but tell you what

this is on 4.23pre

and I do remember having the same problem as you on 4.22

[gilded pulsar]

aaaah sounds really good

[vernal pecan]

hang on gonna check if it was part of the fixes in 4.23

[gilded pulsar]

installing right now to test

[vernal pecan]

@gilded pulsar yeah thats a fix done on 4.23

[gilded pulsar]

Great news, thanks alot for your help Antoine. I am 2/3 into installing to test it on my system.

[vernal pecan]

Do report back when you get your first result with 4.23 😃

[gilded pulsar]

will do

@vernal pecan not working

[vernal pecan]

have you updated the exporter too ?

thats very important

[gilded pulsar]

nope didnt think there was a new as the old one said it work until 4.23

[vernal pecan]

each time there is a new release of unreal, do reinstall the exporter too with the latest version from the studio website

[gilded pulsar]

ok

[vernal pecan]

yeah it works, but doesnt have the new fixes 😃

[vernal pecan]

nah the exporter

hang on

https://www.unrealengine.com/en-US/studio/downloads

here @gilded pulsar

[gilded pulsar]

gotta go now, but will look into it and let you know how it went. thanks for now 😃

[vernal pecan]

no probs 😃

[brisk jewel]

this Vray for Unreal is quite smart, you can rebuild only specific lightmaps,

[forest depot]

Ooo

[jovial coral]

anyone have experience with swarm distributed lightbuilds?

[forest depot]

Yep

Used to use a render farm before switching to gpulm

[jovial coral]

@forest depot on my setup at work, the stability of the remote connections seems to always be really weak, they tend to dissconnect and reconnect all the time, really slowing down the process. did u ever witness this?

[forest depot]

Never, we have a solid network so it wasn't a factor

[jovial coral]

damn, ok thanks

[dusty gyro]

Check for firewalls @jovial coral

[hallow arrow]

it could be Lightmass crashing repeatedly

especially on low ram machines

[jovial coral]

sometimes the remote computers connect and run no problem, can firewalls cause issues intermittently?

the remote comptuers have 128GB or ram

of*

[dusky marsh]

This isn't arch-viz but it's product-viz and it feels as if I'm almost seeing more artifacts in dynamic shadows in 4.23... 😦

there really should be a #datasmith channel....

arch-viz is all about baking, while product-viz is all about realtime

hey @dusty gyro or @vernal pecan you could do something about that now 😛

[vernal pecan]

@dusky marsh heya, do you mean the shadow acne ?

which one is 4.23 in these two shots ?

[worthy loom]

https://www.youtube.com/watch?v=82ZWrI7iZoQ
Hello, any recommend online course for leaning stuff like this ( not the modeling texturing part the but creating UI, function button for each apt, viewing with style ...... ) ?
thank alot

[vernal pecan]

@worthy loom you might be able to find what you want right here 😃 https://learn.unrealengine.com

its all about learning how blueprints work, then building your own tools

[dusky marsh]

@vernal pecan both are, the meshes are just different tesselation levels... but I'm seeing more diagonal lines in 4.23 than before

I submitted a bug report about the very visual grid on the lower tesselation object, and Epic told me to "just bake it"... but I can't

prod-viz is dynamic 😛

datasmith team hasn't really fully understood that yet, I think...

[vernal pecan]

what software is that data coming from @dusky marsh ?

I do think thats a core rendering issue btw, that shadow acne

[dusky marsh]

yes, I bet it is (so next answer is going to be "use rtx", but then VR) 😛

low tesselation is step import into max and then datasmith into unreal

high tesselation is rhino to max and then datasmith

rhino is currently the king of tesselation, imo

[vernal pecan]

have you tried the retesselate feature ?

[dusky marsh]

no

[vernal pecan]

thats new with 4.23

hang on lemme open a project with rhino models

[dusky marsh]

I don't think rhino is at fault, it's a core thing as you said

but I'll try the retesselate thing when I get back into the office

(although I'm extremely happy with the rhino tesselation... minimum edge length and polygon aspect ratio is amazing)

never seen any other app do that

[vernal pecan]

rhino does have a very good tesselator

[vernal pecan]

@dusky marsh can you send me the files for that flower vase ? (step/rhino)

looks like normals are wrong or something

that could be why your lighting isnt really good

also are you using MAX for your scene composition ?

[dusky marsh]

I can't give you CAD data for that, but I can give you a reference to some bug reports I attached files to.

[vernal pecan]

sure thing

[worthy loom]

hello. can you help me withthis crash. my mesh import from 3dsmax usign datasmith. and its has some strange invisible face which i cant add material into it. its crash every time i try.

when i exit edit mode,. the blank part gone. . but when ever i turn on edit mode, its happen again

some how. element 2 and 3 are the same face.

[mild oxide]

Did u try flipping the normals

[worthy loom]

no i havent. i reimport that mesh

and everything seems good.

i notice something wrong ưith my datas mith workflow

so normally, i model everything in 3dsmax, then i create face element 1 2 3 ... for the mesh, but i didnt add the final material , i simply put 1 multi sub material with 3-4 different material go from white to black. then i export import everything into UE4 via datasmith. and then add final material in UE4. ( because i get used to material editor in UE4 more than 3dsmax)
the thing is. everything is fine until some mesh i forgot to add that multisub material for it, then after importing into UE4. it has element with "worldgrid bla bla...." as material element slot. And that is when problem comes, if i draw material into those slot, worked, but if i select edit mode and asign selected material for the face i want, sometime it create blank and overlapping wierd element.

i know my workflow is not the most perfect way to do, but i just want to know what really cause the problem.

[mild oxide]

Worldgrid material is the default ue material thats placed on a mesh without a material. Best i can tell your mesh has overlapping polygons

Or you're trying to add two different materials in different places and theyre zfighting

Do it from only one place and should be fine

[deft schooner]

I've ran into trouble with rtx, changed all the settings so that it activates, it does noticeably change the scene however its telling me to build lighting?? Why

https://gyazo.com/ef3f13a3380f91794792ea90c5f99c98

[mild oxide]

Change lights to movable from static and stationary

[gilded pulsar]

@vernal pecan Hi Antoine, im back at work now and is testing the 4.23 preview. When I import and select the lights it seem to be working - but when I replace them with spot lights they point in every direction.

[vernal pecan]

@gilded pulsar you mean they point in a direction they should not be pointing at ?

[gilded pulsar]

yes its like this after https://cdn.discordapp.com/attachments/375019569804345347/606485883411103767/unknown.png

[vernal pecan]

hang on let me try it on my end

hmm no problem here

[gilded pulsar]

maybe I shouldnt convert them, because it keeps all the good settings just after import like power/IES/Temperature but not after I replace them with spots

strange I must be doing something wrong

[vernal pecan]

what workflow are you using ?

The Convert Actor drop down ?

[gilded pulsar]

maybe I should have cropped that 😉

[vernal pecan]

hmm lets see

huh you're right

looks like that workflow doesnt use the datasmith properties correctly

[gilded pulsar]

is there a different way to do it?

[vernal pecan]

yep

select your lights

and in the details panel

go to the Actor category

at the bottom

then use the drop down "convert actor"

and select your desired light type

this'll keep the right values

[gilded pulsar]

yes!

it works 😃

[vernal pecan]

😃

[gilded pulsar]

is it a bug that it doesent work in the right click menu?

[vernal pecan]

congratulations, you just found a bug, and an alternative solution 😄

probably

[gilded pulsar]

hehe

[vernal pecan]

need to check with the engine guys

[gilded pulsar]

Thanks alot, this saves me alot of workaround time

[vernal pecan]

pleasure 😃

you can batch select your lights and use that btw

[gilded pulsar]

I use "Select relevant lights" that works just fine.

[vernal pecan]

yep

👌

I'll report that bug to the team

[gilded pulsar]

super

[vernal pecan]

also somehow the 3Dicon disappears when you change from a point to a spotlight actor using the right click menu

weird

[gilded pulsar]

is that a way to select lights that is exactly alike? When I use "select relevant lights" it also choose the ones with different power.

[vernal pecan]

it should select the lights with the same type I think

[gilded pulsar]

wich makes convert actor grey

[vernal pecan]

hmm

[gilded pulsar]

instance from 3ds max does not work with lights right?

[vernal pecan]

not sure on that

[gilded pulsar]

I mean lights in unreal

[vernal pecan]

try with "select all type of object"

in the actor category of your contextual select menu

light translation to unreal is still wip with datasmith

its an ongoing work

[gilded pulsar]

Ok got it working

Dont know where you sit in the world but this is the end of my working hours 😃 Thanks again, cya.

[vernal pecan]

have a good evening !

its 10AM here 😄

[gilded pulsar]

4PM here in denmark

[vernal pecan]

😃

hang on @gilded pulsar , I think I found why its doing that behaviour

"Replace actor with" uses the default parameters to spawn a new actor

[gilded pulsar]

aaaah

[vernal pecan]

thats why all its parameters are not matching the datasmith light

soo I dont think thats a bug in the end

more like an unexpected behaviour :p

[gilded pulsar]

Sounds right

[vernal pecan]

but in some other situations spawning defaults is expected

in all cases, do use the Convert actor instead, and it should go as you wanted 😃

[gilded pulsar]

well I learned somethinw new today so its a good day 😃

[fallen geyser]

@deft schooner I had a similar problem today. I believe you'll have to turn off the other static features as well as if it were a dark scene without ray tracing

nevermind, I see you had your question answered in another topic

[feral field]

Any1 experienced Light Proagation ?

I cant get it to work..

[worthy loom]

Hi, how can i fix this problem

my mesh is gone, it doesnt link into staic mesh folder, if i draw the mesh into detail panel, its fine, but its too many mesh

when i open project. it go like this

it happen when i decide to change folder name in content folder.

[fallen geyser]

Looks like the references didn't change when you altered the name of the folder... or something

[worthy loom]

yes. i change the name again. and problem gone

so i should change folder name inside project, not by file explorer

[fallen geyser]

oh, yes!

otherwise UE won't know the difference

[dusty gyro]

never change the name of your folders outside of UE

[mild oxide]

Been there

[honest temple]

Speed level with modular cliff pack, and landfill pack in 4.22
First render! Test build

[mild oxide]

That's not really archviz tho

[worthy loom]

hello, how can i increase number of volumetric lightmap by using density volume, i set Mip min max 0 - 0 . but i dont see any change

[vernal pecan]

hey @gilded pulsar , your max is infected by this virus btw https://forums.autodesk.com/t5/3ds-max-programming/what-is-this-y-u-th-u/td-p/7991084

And you gave it to me with the spotlight MAX files 😄

not really a bad or dangerous virus, just annoying since it creates undeletable dummies in all your scenes

[vast wadi]

Today I learn that Max has its own virus

[static vapor]

@vast wadi Max IS a virus...sometimes

[amber tendon]

Any lightmass experts here by any chance :D?

[gilded pulsar]

@vernal pecan I dont get these dummies in my scenes and I dont work in 3ds max 2018 I use 2017 as said earlier.

[vernal pecan]

@gilded pulsar hmm alright, maybe it came from another file then... lesson learned, everyone should install that security tool anyways 😃

[little star]

Hello, can anyone help me with this problem? The ceiling is in my opinion way to bright. I've already placed LightmassPortals on the two right windws and the left one.

[hallow arrow]

@amber tendon 😄 what would you like to ask?

[amber tendon]

@hallow arrow I am blending static meshes with landscape via a shader (modifying albedo and normal).

It works perfectly fine with movable SMs.

However static SMs cause lightmaps to not respect the new normal and thus create shadowing, creating a seam.

Is there any way to fix this?

Looking perfect here with movable and no lightmass

Static Version does not blend

[hallow arrow]

unfortunately no :( lightmass does not respect most of the shader effects when exporting materials

[coarse kelp]

btw is there any good gpu baker for unreal yet? seen those posts about the intermediate but it says "do not run in your important projects" xD

[forest depot]

ive been using gpu lightmass for 'important projects' ever since it came out

and havnt gone back since

[coarse kelp]

xD

so i dont have to worry too much about it?

[mild oxide]

Nah its v good
