@dusty gyro, okay, I'm stuck - looking for how to go about making an array of static meshes, where do I start?

glossy creek
dusty gyro
never done some blueprint coding before @glossy creek ?
glossy creek
I've just started. I went down to the Unreal Academy last week, and began my education. The concepts are not alien to me, I have some history in programming, etc.
But yeah, I'm a newbie!
dusty gyro
basically when you create a new variable, ou have a little button next to the type
you can click on it and change the storage
as shown in the link you've sent me
glossy creek
Is that something that would be created in the level blueprint, or a new class?
glossy creek
Is there a quick way to add all my static meshes to an array, instead of clicking the "+" and typing in the number of the mesh?
dusty gyro
you can place a Get All Actors with Tag node
and tag your objects with something like "group1"
glossy creek
Thats pretty cool!
Okay, so what does the "Out Actors" feed into? Add items to array?
dusty gyro
you can add your actors to the array with a forloop
or just play copy the out array into your array
with a set node
glossy creek
Sigh, still stuck. Sorry for all the questions. I understand the concepts, just the execution is all new to me.
So I understand what I am doing better, this get all actors with tag, what exactly is it outputting? Is it an auto index array of each actor nodes ID?
And I'm going to avoid forLoops for now, so I would rather go with the "set node" route.
Maybe this can do it - https://answers.unrealengine.com/questions/52091/how-to-add-selected-actors-to-an-array.html
vivid moss
You need to make one array variable that references Static mesh actors. After the GetAllActorsWithTag put a ForEachLoop. Connect the newly generated array variable you created to the Add node and the result from the ForEachLoop to the singe input of the array.
Oh now I read that you want to avoid for loops...
You are outputing the actors that has the tag.
I dont know what you are trying to do...
dusty gyro
well if you want to avoid loops... you can use map arrays I guess ? And use the find by key node
vivid moss
But why not using for loops? You will only execute this once at BeginPlay.
@glossy creek
And btw you tagged the actors on the wrong place. Make sure you make the tag on ActorTag not ComponentTag.

hey, i am using 3ds max with turbosmooth and mesh smooth but when i export to ue4 it becomes low poly
anyone @ me if they know how to slove it
royal osprey
If you want to keep the base geometry as is in max you could use tesselation in Unreal, not sure if it will smooth it or just subdivide it, I haven't played with tesselation much. The other alternative is to freeze your geometry in max, I am not familiar with max but in other software you can "apply" the modifier so it's no longer a modifier and it alters the geometry itself.
bitter pine
i cant see an option called apply modifier
royal osprey
it's called collapse in max I'm told by a co-worker
right click on modifier and select collaps
bitter pine
ok

pure sinew
Hello everyone! I was wondering if anyone has looked into building lighting from several levels in one go? I.e. queuing up the workload on network Swarm. Thanks in advance 🌞
dusty gyro
@pure sinew try to look into sublevels 😉
if you have a main level, and multiple sublevels, you can bake all the sublevels by baking the main one
pure sinew
hm.. that might be a solution, but we already have loads of levels with sub-levels, I think we did it that way originally because of some issues with packaging the project. Might be worth looking into more though, thanks 😃
any idea if a queue system works for Swarm agent?
dusty gyro
no idea :/
I know you can bake levels with a console command
but never really looked into it
pure sinew
ok, thanks anyway though 😃
deft oasis
Are there any limitations to using sublevels?
native perch
Just Trying to make stack game 😃
how can i rid of flickering?
simply every block of this static meshes have 10x100x100 dimensions
every next block placed just +10 by Z axis
and some kinda weird flickering appears
deft oasis
^might be overlapping meshes
Try adding each new block by 10.1?
native perch
yep
no difference
if i pick 10.5 its gone away, but distance between meshes already visible
i googled , some say to change bound scale in Rendering tab, but no difference
deft oasis
If you're using the UE4 cubes then I might suggest trying to make the cubes in blender to fit UE4's scale, via this tutorial
https://youtu.be/3TqQH1fZAtM

i created Cube in blender , but after watching this video , im not sure about lightmap i created
Thanks , @deft oasis for video
can you please check lightmap and uv unwrapping, am i done it correctly?

Unfortunately I can't check it for you as I don't have an internet connection at home right now
If you did it as they did it in the video then it should be fine

anyone know how to get granular bp access to archviz character? i've been struggling with this for a long time, i love its smooth movement, but it has some settings i want access to to change, such as walk movement slowing down when camera pitch reach peak + or -
sharp sorrel
Re-lighting of a scene by epic games + added shield and other stuff to make scene my own. Unreal Engine. Thoughts?
solemn hawk
@cyan ether you can access the movement component of the pawn
cyan ether
yes can access the entries to change things, but seeminly not any bp level control
i'd be happy to scrap it if i knew how to replicate the smoothed out controls
solemn hawk
I know they're exposed on the first person pawn, not sure about archviz pawn though
cyan ether
ya, i think i'll persist with trying to mod the first person pawn over time
to get dampened rotation and movement
its less compromised and most tutorials and documentation assume you're using that
feral cradle
Hey guys im interested in making some artviz models to sell what do you guys need or want most?
solemn hawk
so I imported an fbx scene into unreal because I need my items named in the content browser (not just numbers from datasmith) but I also want those assets placed directly in the level instead of in a blueprint.
However, you can't just copy items in a blueprint and paste them in a level. Anyone know of a workaround for this?
gentle osprey
Are the items nested below the BP in the hierarchy?
Also, did you mention this in the datasmith forum? That's a good idea for future development.
It seems too that you may be able to use the datasmith information to work with the asset metadata for identification instead of the import value if that is something valuable to your workflow.
dusty gyro
@solemn hawk have you updated to 4.20 studio/datasmith ? You can now dragndrop your imports and it places them directly in the level with the proper hierarchy. Also it uses mesh actors attached to dummies, and no blueprints.
solemn hawk
Omg that’s so cool!

Thoughts and feelings? Lighting done in Unreal. Not Arch viz but im sure you people have something to say about it.

@tribal sluice thanks
sharp sorrel
@tribal sluice Thanks. I am still changing it up.
Some more changes. Thoughts? Lighting in Unreal Engine.
hard oar
@sharp sorrel well congrats! what i think is that you need to give your image a better shadow play. watching the second image you sent, shadows are way too light in some points (as in the columns on the left side). saying this cause you could give your image more effect and meaning by giving importance to the light beam and the "altar"
sharp sorrel
@hard oar Thank you, will see if I know how to do that technically speaking
hard oar
in short words. i would give a "light importance" to the light beam and altar and a "dark importance" to the rocks. this does not mean that rocks have to be black, but bit darker, just to give a good line to the image
sharp sorrel
Some more tweaks, and hopefully improvements. Lighting in Unreal still.
@hard oar something like this?
dusty gyro
@sharp sorrel This is really neat and all but... Is it really archviz ? 🙄
sharp sorrel
@dusty gyro not per say, but in arch viz there is a lot of lighting, thus relevant to get opinion and feedback.
dusty gyro
hmmm
dark oriole
That's really stretching it
dusty gyro
feels a bit weird to see fantasy stuff in a channel where we mostly talk about architecture
dark oriole
#work-in-progress would be the most appropriate unless there was a specific technical question, just getting feedback should stay in #work-in-progress
sharp sorrel
@dusty gyro Maybe, I will post my lighting for arch viz then if it has to be specifically real 3d model of interior and such. The process is still the same.
still adder
Hi peeps! This seems the most relevant place to ask. I've barely used stationary or static lights so far due to the nature of the scenes and projects I've been working on. However now that I do have to use them, I'm running into an issue. I've got a Scene with a nice reflective polished floor, and I have a few cabinets that have glass surfaces. These cabinets are scattered across the place. I've placed one big sphere reflection capture. It catches the reflections on the ground really nicely, but on the cabinets, the sky is reflected in a way that it's incredibly bright, we cannot see through the glass anymore.
Any ideas to work around this issue?
royal osprey
I came across a video explaning reflection capture spheres and they recommend using one with a large influence radius for the whole scene, and smaller ones for different rooms of your level. if you want more realistic reflections on flat surfaces you can use a planar reflection (and enable it in prferences) This is very resource hungry, so for a realtime application it has to be used sparingly.
still adder
The one big reflection capture provides just fine for the mentioned parts, it's only screwing up the glass cabinets. Planar reflections are pretty much out of the question, since they render the whole frame twice. We are working for VR and due to the density of objects and the required visual quality, we cannot afford that.
royal osprey
One trick I have used in a similar situation was to use geometry outside of my room to reflect that instead of the sky, won't work if you are also stepping out. To get better glass materials it's a good idea to use a fresnel node to control the reflection. so it's more reflective at a steeper angle and less reflective looking at it straight ahead.
still adder
Thank you, I'll delve more into the material then 😃
royal osprey
also, for panes of glass don't use refraction
in real life it's hardly noticeable on flat glass and it causes all kinds of headaches in Unreal.
royal osprey
all right just making sure
still adder
Placing small reflection captures around the cabinets does make them better, however there are still some strong reflections from certain objects, and the only thing I could do to make it better is to exclude said objects from being captured by reflection at all
royal osprey
Reflections is the biggest hurdle right now for me in Unreal, multiple reflective surfaces like in a fancy bathroom, are a challenge.

Alright, I'm going to architectural design classes this fall and I want to have some cad expirience before hand, you guys know some good (and free) cad programs that will work well with ue4?
royal osprey
Epic came out with a tool called DataSmith that is geared towards getting CAD data into Unreal, but I'm unsure if it works with any free packages. We have a time tested workflow that was stablished way before DataSmith came out. We use Draftsight (free) to convert the 2d CAD drawings that we get from clients to .dxf Then we take the dxf to our 3d software of choice and extude the walls up and prepare it for Unreal. Our 3d software is not free, but you can use Blender, wich is great and free.

can anyone clarify what datasmith is is it a way of taking an architects 2d auto cad or Revit plans directly into ue4 or something else I'm trying to score a job at an architects and looking for a simple solution to transfer their work into ue4 cheers guys
dusty gyro
@hearty rock so far you have to get your Revit model through 3dsMax then export it to datasmith to get it in unreal (or go FBX, by that's a lot more work)
at some point they will release a native Revit addin to send it directly to unreal 😃
about 2D plans, this is not supported
I'm not sure how they would do it, and why you would want to import 2D stuff in a 3D rendering engine 🤔
hearty rock
i can see that i can take a model from Revit to unreal as a fbx which puts all the separate walls etc. into unreal at the right scale and as a full building and also a 2d model from revit can be put into 3ds max for further manipulation so I'm not really sure what data smith is for
dusty gyro
datasmith is a workflow tool
that allows you to import meta data, customize how your import your models, etc...
- lots of substance materials for archviz
- custom support
python scripting
hearty rock
ahh ok thank you quick question i have a b.a. in games design but i am leaning more towards architecture how difficult would it be to do my masters in architecture would it be impossible at the mo I'm just getting used to Revit but i know nothing about load bearing /engineering etc.. i have always worked with 3ds max for modelling so Revit seems bit easier but I'm just playing with Revit at the mo
lucid orbit
so what 4.20 actually helped for archviz besides dof/studio?
gentle osprey
@hearty rock TO GET YOUR MASTERS IN Architecture you would need to take structures classes, history classes, design theory classes all specific to architecture. I would be highly suspect of any architecture schools which would transfer your game design credits in for architectural studio credits.
feel free to DM me with any questions about arch school, as I don't think that would be part of #aec-visualization scope.
dusty gyro
@lucid orbit afaik they improved performance for translucency with VR ? 🤔 Havent tested it yet though, still deep in the new Studio stuff.
hard oar
Anyone know if the solved the Lumen issue on 4.20?
dusty gyro
@hard oar what kind of problem was it ?
hard oar
Lumens intensity was out of control in 4.19. I mean that it wasn't corresponding to real Lumen intensity
royal osprey
For me the best addition to 4.20 is the area light, and fixing the camera rotation bug when working with cinematics. (that was technically fixed in 4.19 but I skipped it)
hard oar
I am designing a cloth shop and I need many spotlights.so I need precision and can't work with area lights into that
dusty gyro
can you give me some values @hard oar ?
I'll do some screenshots for you if you want
just noticed I had some nasty rendering artifacts when moving around lights with IES O_o
@dark oriole had this kind of stuff already ?
dark oriole
Yes, confirmed fix for 4.21
dusty gyro
ah nice
dark oriole
And nobody noticed it, somehow, until I randomly decided to turn on forward rendering and spawn a single light
Somehow I suspect forward is not the most popular feature
dusty gyro
:/
hard oar
I have 50 static spotlights in my shop and in real life the are all between 14-20 W. So it will be around 1300-1900lumens each. If I set my spots with real Lumen intensity, I got a whole white build
Now I am scaling them down checking for the right intensity
dark oriole
The difficulty with using real world values for lights right now is you also need to decrypt the nightmare of exposure settings
dusty gyro
exposure in UE is such a hit and miss
dark oriole
And got a total redesign in 4.19
So all we knew to be true is up in the air now
Daedelus made an hour long rant video about how hard it was to use properly
hard oar
I am trying again scaling lights by 0,01
hard oar
Ok so with 50 spotlights, set them to 20lumens (instead of real 2000) looks good
I didn't touch Exposure for now
dusty gyro
best would be to change the exposure values in your PP volume to 1min 1 max
do your lighting tests, then tweak exposure
god I already miss GPU lightmass on 4.20
@hard oar https://i.imgur.com/yo0rzUe.png
this is the result with baked lights
I used different IES on each, but the intensity is set as 1300 lumens on all of them
attenuation radius is 500, lights are placed 300 units (3meters) above ground
hard oar
It looks too bright to me
dusty gyro
values still fucked then
do you have any IES profiles ?
you could use the intensity of these instead
although it might still not work 😅
dusty gyro
yeah static works
but well, you cant power them off after the bake, gotta use lighting scenarios
wait you use stationaries with that much lights ?
how about overlapping ? O_o
hard oar
Nope I use stationary on other scenes. Not in this kind of archviz
dusty gyro
ah right
shame IES wont work on movable lights
you can still use stuff like light functions to fake IES profiles I guess
hard oar
Looks decent now
dusty gyro
woo looks overbright as fuck
hard oar
Can't take screenshots sorry. Just pick from camera cause it's not my pc
dusty gyro
rofl
hard oar
I can work with exposure now I guess
dusty gyro
exposure makes a lot of difference
I've had better results going for lower light intensity then tweaking it with exposure though
rather that going from too bright lights
you loose a lot of shadows
hard oar
Well in there is all white except for the floor. I still have to import materials
dusty gyro
keep in mind if your walls arent white your lights will bounce differently
hard oar
Aye true. I'll try to lower intensity down a bit too
hard oar
Ye but still waiting for the material list from the client 😂
dusty gyro
😅
exposure compensation at 2 on the first screen, 1 on the second
min/max brightness of the exposure at 1 instead of .1 and 2
makes a world of difference
this scene has no light other than the skylight HDRI btw

either use dynamic lighting for your foliage

gilded pulsar
Hey ppl. I have imorted a scene with datasmith from 3ds max. I got about 800 material ID's in max. But in unreal when I look at an object it gives me the "original imported material name" which seem to be the ID from max but only with a 2 digit number -1 so 722 becomes 21 and 357 becomes 56 and 473 becomes 72. Can I only have 99 materials in unreal? is there any way to get the correct ID number from unreal so I can find the correct counterpart.
gilded pulsar
dusty gyro
@royal osprey already geeking out at the idea of getting a geforce RTX at home and quadro RTX for work
@gilded pulsar I think its actually a limit of max
wait no
it could be a limit of unreal
either way its a really bad practice in realtime to have that much materials on a single mesh
gilded pulsar
It is very good for Archicad -> Max use to have that many materials. We have a good workflow, and have had it for years. But Unreal have some problems with it. Was hoping to just throw it directly into Unreal without too much work and be part of our 3D package for our customers. Doing a few hundred shops a year, could be nice to offer VR too if it could be done without too much work.
dusty gyro
What I'm doing is splitting per material. You could then fuse them by material type or something
Also it looks like some materials didn't even get through the conversion (the "WorldGridMaterial" slots)
But then most of our projects don't have more than 4/5 materials per object (since it's mostly structural stuff)
small spruce
Oh wow... @gilded pulsar am I understanding that right? Did you import a mesh with >99 materials? That's super interesting to me. I've never seen that before. Although I'm relatively new to ArchViz
In the course of gamedev I've never had a need to push that. I'd be interested to know for sure if that is a hard limit of the engine.
But...on a different note. I came here because I had a question for you guys here.... Does this bedding look WAYY too glossy to anyone else?
left flare
Looks pretty glossy.. maybe even inverted roughness?
You could try slapping a one minus between the roughness texture sample and the input on the material node
small spruce
Well see...
That's what I thought... but. That doesn't seem to help much either... The roughness is derived from a Gloss Map -> (1-X)
left flare
What's the gloss map made by? There's some older specularity related maps like that that don't translate well to PBR
left flare
That looks really wierd
small spruce
This is basically what my material looks like. This is a direct import from Datasmith
left flare
The multiply by 1 -x is interesting
small spruce
I'm trying out datasmith and it looks like Datasmith's material conversion does not like my source scenes
left flare
makes me wonder what the gloss map actually is
Try using the G channel plugged directly into roughness
small spruce
In my roughness thing, (circled yellow) I'm wondering why on earth datasmith squares this value
left flare
assuming the texture isn't HDR, that's gonna effectively sharpen the texture
WHich is also wierd
small spruce
doesn't appear to, but honestly I'm learning ATM. So, why did you suggest using just green channel?
left flare
Looking at the texture, it's primarily yellwo, which is red + green
just assumed that since roughness would be near 1 on the bedding, that the g channel was the most likely channel
it's either that or red, but that had some AO looking artifacts on it
so maybe plug red into AO?
small spruce
Red into AO doesn't appear to have any noticable impact
small spruce
lol. So it appears I have a diffuse, gloss, normal, and reflection map for each of my materials like this
I assume that the insane glossiness has something to do with a combination of that crazy complicated specular path, and the fact that the roughness gets squared.
But honestly, I have no idea what's going on. Imma have to open this in max and look at it. I didn't make these meshes, textures or mats. So I'm not sure what's going on. All I know is that datasmith did a lot of UE4 Mat work to try to mimic the Vray textures.
Silly me. Thought things would work perfect out of box. 😆

Datasmith material conversion is a bit hit and miss 😅
We have our own material library made directly in unreal (but then we use Revit materials, which are 🤢 )
royal osprey
We have made an ever evolving collection of master materials that we use on all projects here. The idea is to make material instances of those and teak them instead of making new materials for everything. The masters are crystal, glossy, masked, metal, gold, wood, mirror, cloth, rug, velvet, water and emisive. There are always special materials that need to be made but for the most part that coves it.

@small spruce when I have glossinees map and I need roughness I do not multiply, just 1 - themap, for the pow 2/power .5 it's just a gamma thing IMHO: linear workflow/gamma 2.2 sort of thing it's to gain more controle in the near 0 values
also roughness is (in my workflow) NEVER close to 1
barely never above .5
I use diffuse if I need more than 0.5
small spruce
Yea guys. Thanks for the tips. That all makes a lot of sense.
I definitely come from the game side of things, but and really trying to get better with ArchVIz. Really appreciate the input.
royal osprey
I'd like to now if we'll need to upgrade to an RTX GPU or will raytracing be available (even if it's not realtime) without them.
dark oriole
They had performance numbers during the presentation indicating that it did run on pascal cards, but around 10x slower. So we may see it as an option without RTX GPUs in Unreal, but too soon to tell until we actually just have it.
dusty gyro
Yeah it's just gonna be much slower
But still available for older cards
For archviz videos or rendering purposes it might be alright
For real-time or vr though
agile star
Hey guys, I've just started using datasmith & unreal studio and i'm having issues with my light intensity being crazy high when imported with datasmith to unreal
I can't figure out what's causing this and can't find any people with the same issue but it is happening with multiple imported scenes
I've been dividing the light intensity in max by 5000 before datasmith import & export but it doesn't seem like a very reliable solution
Could there be a setting unreal doesn't like that's converting incorrectly?
This is the best help i've found so far but is it still the recommended solution?
https://forums.unrealengine.com/unreal-engine/unreal-studio/1456695-3dsmax-vray-to-ue4-via-datasmith-lights-too-bright
if anyone can help please @ me so I don't miss it, cheers 😃
pale prairie
royal osprey
it depends.. there are many surfaces that don't need much definition in the lightmap (reflective woods, stones, glass, chorome, colorful rugs and drapes etc etc) But white walls will need a ton of resolution to look right. To avoid long rendertimes start low rez and improve on the things that you see need it.
agile reef
@royal osprey Yes, it is for white walls
What I don't understand is, if the uv lightmap created inside the 3d software (Blender in my case) has anything to do with the Lightmap resolution inside Unreal
royal osprey
@agile reef it does to some extent. The larger your piece is in the UV the more pixels it will receive in the lightmap image. But the total resolution of the lightmap is defined in Unreal.
gilded pulsar
Hey all, im having problems with blurry/low setting textures in my editor viewport. And the engine scaleability settings seem to have no effect. Anyone who can help?
If i open a single actor in static mesh and exit the window, it updates to full resolution textures on that specific object, but thats alot of work to do on every single object every single time I open up the project.
royal osprey
sounds like a "texture streaming" issue, you can turn it off, but your performance might degrade (if it even fits in your graphics memory)
gilded pulsar
thank you I will look into that possibility 😃
gilded pulsar
where do I set my texture streaming`?
royal osprey

Late answer, but... That was the solution, thank you!!
acoustic fog
I too have a shadow issue but its Low poly self shadowing... is this fixable other than just increasing poly counts?
dusty gyro
@acoustic fog this looks a lot like a bad unwrap to me
for the lightmap UV that is
all these triangles are separated islands right ?
acoustic fog
all the models do come out of sketchup, and for the most part the unreal lightmapper does a decent job but for this, it cant work it out...
dusty gyro
urf
yeah that's defo an UV problem
see your model has a lot of "islands" that are separated faces
problem is, your lightmap has a limited number of pixels in your UV space
if you dont attach these small faces together to form a common island
you'll have half pixels on your faces
resulting in these weird bakes
you're using datasmith right ?
you can try to tweak the lightmap UV settings in the object properties
acoustic fog
uh no, whats datasmith?
dusty gyro
oh
datasmith is a workflow suite for CAD and AEC
basically a bridge between softwares and Unreal
could be worth trying their sketchup pro exporter (if you have sketchup pro)
acoustic fog
yeah i use pro, just having a look now
dusty gyro
can you share that chair model ?
I can have a look at how to fix it in unreal, or in max/datasmith
but that UV is 100% the problem here
acoustic fog
dusty gyro
right lets have a look
acoustic fog
yeah its just a simple chair and table set... the untextured section did used to have a material on it, but it was still an issue, hence why atm there is nothing on it
acoustic fog
yeah the downside of a simple editing program is its full of bad practices...
dusty gyro
what file version is that chair on ?
acoustic fog
2018
acoustic fog
acoustic fog
haha yeah although what we have accomplished so far has all come from sketchup so its not all bad... just in places it can be very annoying
dusty gyro
sketchup tends to do a lot of weird stuff that doesn't bode well with unreal
like separating each face from eachother
acoustic fog
woops
dusty gyro
:p
left is after the edge merges
looks a lot better
right gotta grub, bbl, I'll show you how it looks like in engine
acoustic fog
be careful not to show me something that looks awsum, otherwise ill end up needing everything going over so far... and there is a lot of stuff hah
but thanks for doing at least this bit 😃
dusty gyro
Haha well making stuff look awesome is kinda my job, can't really stop me now !
acoustic fog
oh and iv set up all of datasmith into the project too,
incase that solves other issues later
dusty gyro
You should be able to install the exporter plugin for SketchUp then
acoustic fog
already have done
acoustic fog
it might help other uv stuff later, im sure theres plenty that can be redone
dusty gyro
:)
dusty gyro
right back on it
dusty gyro
@acoustic fog https://i.imgur.com/q4vMYjZ.png
corrected smoothing groops, corrected UVs
each part of the chair has its own UV/mesh here though : the backrest is composed of two parts
with 128x128 lightmaps
acoustic fog
oooo
nice
yeah the inner part is the striped white leather, then the rest is red leather and chrome legs, white trim... but that looks good
dusty gyro
I'm finishing the first welding pass on the rest of the chair and I'll send it to you
acoustic fog
thanks for that, its certainly one of the more jarring errors

lost island
hey, general modeling questions:
i'm working on a small house scene with multiple rooms
do i want each and every wall, floor and ceiling to be it's own mesh so i can give it it's own lightmap?
currently i have grouped the walls in each room as a single mesh
dusty gyro
yeah you want them to be separated
unless your scene is very big it won't cause much performance/culling problems, and your lightmaps will benefit from it @lost island
lost island
awesome, thanks
other 2 questions i had: my room geometry is all made of planes, that shouldn't matter should it?
as opposed to boxes or something with a thickness to it
finally, i modeled the rooms in sketchup, in feet on a quarter foot grid. when i export it and convert it to centimeters, it definitely doesn't line up with the grid in Unreal. will that pose any issues?
modest bough
Hey, so I'm looking for advice on how to make this look better. I'm using Luoshuang's GPULightmass, customized to NumPrimaryGISamples=128 and NumSecondaryGISamples=32. I'm also using the new Rect Lights on the windows.
Right now, the only parts I know need work are the chair's quality (looks very jagged) and the floor (it looks wet).
quasi kernel
the dark wood to the left blends in too much with the chair. you need a rim light to show the outline of it a little. Your trees also need to reflect onto the floor tiles. from what i can tell, that looks like a photo wallpaper for like a desktop or something similar (if its not, then you're doing damn good)
rug texture too low, and you're gonna want to shape the rug so you can see some AOC below it. that way it looks like its resting on top of the floor, instead of clipping through it.
aside from that, your mattress looks damn real, the cushions on the chair are real nice looking, while the side table is basic, i think its neat. everything looks real nice, man. composition's pretty damn clean.
dusty gyro
@lost island it wont pose an issue unless you want to use a VR headset (in that case the scale will be off). For the planes, if you bake your lights it should not cause any problem, but don't be surprised if you see some small leaks.
@modest bough I'd put a little higher roughness on the floor, its a bit too reflective here, looks like someone sprayed water all over it 😃
lost island
@dusty gyro yeah my initial concerns were some leaks where the walls/ceilings meet
are there other solutions to that besides not using planes?
dusty gyro
you can use GPU lightmass @lost island
since it bruteforces rays your chances of leaks will be minimal
lost island
oh, i haven't even heard of that possibility
where can i learn more about setting that up?
is that it? there is no official epic support for that yet?
dusty gyro
yup !
luoshuang joined epic a few months ago 😃
this is a temporary solution, but next year we'll probably see it in engine
lost island
wow that's awesome, thanks!
modest bough
Alright, I took some advice and improved my scene, here she is:

@gentle osprey what kind of fails ?
gentle osprey
ID:107 fails. You helped me through them this weekend. Thanks again
Although, I'm still not entirely sure why the build was failing from a previously fine project.
hearty rock
Can anyone explain why epic are making unreal studio an annual fee rather than monthly it seems like they will be cutting out a market of people who can’t find cash up front and how is this any different from just straight up importing also it seems an odd move to go for sketch up pro native rather than revit 🙄
dusty gyro
@hearty rock revit support is coming at some point
this year, early next year, no idea though

Ahh ok thanks for the reply

Hey everyone. I recently got commissioned to create a 3D render of a set of modern flats in a fairly standard arch-viz style and one interior scene. Its a first for me and I'm having a hard time coming up with a price estimate. Anyone got any advice on the price range of these kinda jobs?

@latent orbit I count my days of work and multiply by my rate. It's the only good way I know
latent orbit
@olive pebble Yeah thats what I was thinking, the client just wants a price estimate up front and I really have no idea how long its going to take
olive pebble
hum ...
does he want picture or VR or movie ?
if it's pictures forget unreal if you are not really confident and fast with it
how defined is the briefing .....
how many time he will ask you to change the sofa ?
latent orbit
He just wants some renders, and he said maybe a small amount of movement. Its basically a set location that needs to be reconstructed. Fairly simple modern flats with some surrounding foliage.
I think its the first time hes commissioned something like this so its also prob quite new to him.
I'd feel a lot more confident working in Ue4 than rhino or maya or something haha. I think I might just have to treat this one as a trial by fire if I get it
barren crest
@latent orbit just so you know, measure your time that you can do it. I charge per hour. I do an entire project based on that hourly rate. I also add another 15% to the hourly for improvisions, and all the other things I would need for taxes.

signal narwhal
Hello Guys , My shadows are coming pixelated after building the light in production settings. Lightmass resolution is "Green" 512-1024. I tried that "Static Lighting level Scale" to lowest which is 0.01. But nothing working . Also the lights are static . How can i make my shadows more sharper without increasing the resolution that much.
Thanks
dusty gyro
@signal narwhal you can disable compression of the lightmaps, improve your lightmap UVs, augment further the resolution to orange/red debug color
green is a bit too low for archviz
hard oar
Anyone tested the new lighting physics on 4.21?
dusty gyro
@hard oar got the editor open right now, what do you want to know ?
hard oar
I'm setting a spot light to 1300lumens like real life ones but it looks way too powerful in ue
I don't get how to set it up correctly
hard oar
Ye I don't understand why they don't make them with correct parameters
Or it's me missing something
dusty gyro
also, be sure to disable eye adaptation
/auto exposure
do you have a ref pic of your 1300 lm lamp ?
hard oar
NOt renderend tho
dusty gyro
seems very bright for sure
dusty gyro
getting the same results when baked, way too bright
try 130 instead @hard oar
looks a lot better

Does unreal studio have the same lightmass settings as unreal ?

@feral field yep, Studio has the same tools than UE4 + The Datasmith Workflow, more templates and a bunch of nice tools like free Substance Materials, a dedicated support and a whole lot of tutorials on how to integrate AEC and CAD data to unreal

Relevant to all Datasmith users who struggle with drawcalls and optimization of your scenes ! https://theia.io/optim/
basically an Interface to make rules (like python scripting in UE), but with a User Interface

this looks like what i need
having trouble with datasmith flexibility
with it not quite putting powerful enough lightmap res into each mesh stuff like that
dusty gyro
Yeah it looks like a good prep/manager for datasmith stuff
ancient pasture
does anyone have problems with using datasmith from max to unreal? it feels as if the scene in unreal is huge cause I can barely zoom on any object
cyan ether
cause of viewport clipping?
cant say i've had problems, scale wise it gets things right and does conversion, ensure your max scene is built to correct scales
dusty gyro
@ancient pasture place a mannequin or a player start entity in your scene to compare :)
Or a default cube, which is 1m*1m
ancient pasture
Oh ty! :)
dusty gyro
If the scale is off in unreal, it probably is too in max :p
torn vine
Had a scale problem before and really wished there was a way to scale multiple objects together in Unreal while keeping the relative distance the same.
strange stream
hi there... I am about to kill myself ...how can I get the real size world material to match my asset ?!
to make myself clear ... if I have a cube 1 11 m and add a material with texture 20 cm it should tiles 5 times in each side ... am I right or what ?
gritty summit
set tiling to match the size in material options
dusty gyro
@strange stream can you show us your UV ?
you might have a slight offset in your unwrap
dusty gyro
what is your material setup ?
dusty gyro
hmm yeah
and you say it is perfect in max ?
can you screenshot the UV in unreal ? in your mesh properties
strange stream
dusty gyro
well
your UV is fucked 😉
UV0 is your texture UV
UV1 is your lightmap UV
UV0 should look like this (roughly) https://i.imgur.com/rkatYBB.png
strange stream
this is a texture uv it is not important to be inside the uvs square
I know that I have to arrange a light map channel but I am taking about texturing now
dusty gyro
oh I see what you mean
you used a box UV or a face UV
not an actual Unwrap
can you upload your mesh here ?
strange stream
it is an actual unwrap but it is non normalized to take the world size of it
dusty gyro
don't know what to say then 😦
are you using datasmith ?
have you checked the other UV channels in unreal ?
strange stream
I am not using datasmith ... to tell the truth I still think that datasmith needs to be more developed < I love its idea but I doubt if they can export things the way it should be < I mean it is not about the datasmith it is about the way you create your mesh inside max
dusty gyro
there's always gonna be a data loss of some sort for sure
when you import your mesh, what settings do you use in your import window in unreal ?
also, do check other UV channels in unreal
your good UV might be here, but maybe unreal moved it to another channel
lucid orbit
hey guys, two quick questions, is gpu lightmass implemented and is sketchup datasmith plugin extended to free version of sketchup?
dusty gyro
@lucid orbit if you mean implemented in the main branch, nope and nope for the free version of sketchup, you need sketchup pro
lucid orbit
oh well, thanks
dusty gyro
no probs 😬
lucid orbit
but does it mean that gpu lightmass is on non-live branch or? I know luoshang got hired some time ago to work on native gpu lightmass @dusty gyro
dusty gyro
@lucid orbit means you have to update it on your own, and its not gonna be available directly with each new major UE4 revision
yep luoshuang is now working on the lightmass 2.0 project
along with a very strong team of talented raytracing devs
lucid orbit
and this 2.0 is going to be implemented in ue4?
dusty gyro
yeah at some point
sometime early next year I think
we've been speculating for months about the features of the new lightmass
but I'm pretty sure it will be progressive GPU baking using techs like RTX when available
and a strong realtime GI too
lucid orbit
ouch, i really hope they can pull out production ready gpu baker for non-rtx gpus
dusty gyro
surely it'll fall back to CPU (and be slower)
lucid orbit
I would be sad to hear my 1080 is useless 😦
dusty gyro
I'm sure we'll have fallback a GPU lightmapper for all type of GPUs, not exclusively RTX or Nvidia
RTX lightmapping is going to be a bonus feature
gilded pulsar
Hey all, I am using Datasmith to my 3ds max scenes. My scenes has materials above ID 99. I can clean up my multisub material and have less than 60 materials but the ID tags remain as 212, 377, 583, etc. If I change theese to ID 1,2,3,4,5,etc... it will not fit my scene. Do you guys know a way to handle this?
dusty gyro
@gilded pulsar first off wtf why is your multimaterial fitted with that much stuff
Secundo, try to split it in smaller multimaterials :)
Very bad practice to have so much material slots in one mesh in real-time engines
gilded pulsar
That my friend is a very good question :)
You see, the architechts in my company is using ArchiCad. In fact all the brands in the company is using the same template in Archicad so the materials ends up in the same multisub material. It works wonders in 3ds max for visualisation purpose. But now I try to take the projects into the new century with Unreal where I run into problems.
I am trying to find a pretty fast and automated solution because with some luck I can implement this into our daily 3d solutions, it could help both architects and customers alot.
dusty gyro
@gilded pulsar there could be a way to split your meshes by material(s) with a maxscript 🤔
or tell your guys to move to Revit 😄
gilded pulsar
Right, I will move 50 architects to revit 😉
gilded pulsar
true
dusty gyro
btw, we did on our end 😂
gilded pulsar
Well, Unreal is not really a thing yet in this company
dusty gyro
full service of engineering went from 2D autocad to revit
gilded pulsar
Archicad works great here, so no need to talk about that
gilded pulsar
been there
gilded pulsar
cant find anything that works, and have posted on the forum
gilded pulsar
hehe perhaps, but im not much of a programmer 😃
Was hoping to find one who were more clever than me 😃
dusty gyro
you arent the first lad with this problem though
I remember seeing someone with the exact same problem
so much material slots that it was breaking UE
dusty gyro
performance wise though its not the best :/
gilded pulsar
not the best, but it works...
got 60+ fps
got 6 million polys in one shop
60 matersials
dusty gyro
going for VR or plain 2D ?
gentle osprey
Meh, ArchiCad, Revit, Excel, it's all the same tool. Comes down to who is using it mostly. :]
cyan ether
nice
i really like the latest mat instance developments with datasmith
but man i have no idea what's going on with area lights, ue4 standalone now has area lights, albeit invisible, datasmith's blueprint lights come with emitter materials that at some stage become locked out, don't instance the mat or the light, and most confusingly the bp light has 2 intensity values, one candela one noname units

Hey mates. Newbie in arch-vis here. Wanted to ask some simple beginner questions.
Got a personal project about a new type of Architecture I want to try (houses parolles, shops etc) It will be something like a seaside city part in UE4, possibly no light baking just a real time env. light.. It will no doubt take a long time so I wanted to ask you about beforehand.
Should I just do all the models in 3ds max with UVUnwrap, textures ready (like characters, assets etc) and import it to Ue4 or is it actually better to use basic cube,plane, sphere of UE4 in engine to create the models and then create suitable materials to them ? Will this cause light leaks etc ?
Thanks for reading. Also have an operator-cutie for payment 😉
dusty gyro
@onyx shard EU standards, that's a French project (like most of the projects we do 😉 )
@opal mason operate fully in max for your models and UVs (lightmap UVs can be done in either max or ue4 with auto generation)
you dont really want to model in max, unless you do very early blocking of your levels 😃
dusty gyro
Another import, done rather quick, with Unreal Datasmith for Revit
1H prep work, half an hour bake with preview settings slightly tweaked
opal mason
@dusty gyro So basically I just better use a 3d modelling program all the time ?
Thanks.

@dusky marsh hey there ! Is that your post on the forums about high CPU usage when importing datasmith stuff ?
feral field
Can you package a game with Lous Gpu Lightmass ?
dusky marsh
@dusty gyro yes it probably is
4.21 freezes up and takes a very long time with 100% cpu anytime I reimport datasmith now
even on not so complex stuff
dusty gyro
@feral field yup, no problem since GPULM is an editor tool 😃
@dusky marsh what software are your models coming from ? Max ?
also, Luoshuang just released GPULM 421 ! Rejoice datasmith users 😄
feral field
@dusty gyro Awsome! Thanks for the answer 😄
dusty gyro
GPULM is a substitute for the default CPULM : the end result for your project is the same, some nice looking lightmaps for your scenes 😃
dusky marsh
@dusty gyro yes, Max
feral field
at GPULM 421 is IES profiles still not supported ?
dusty gyro
@feral field hang on lemme have a quick look at it
hmm
cant even make em work before the bake
something's fishy
dusty gyro
😬
feral field
Better to live without em, instead of waiting 1 hour for a bake
feral field
Yeah kind ooof 😮
Gonna try on my scene now after gpu driver update
Drivers to old for GPULM 4.21 haha
dusty gyro
these profiles are sooo bright though
after the build
looks like crap if you dont build it 😄

Haha watch out before you get blind

Im back after gpu driver update black out, seems to work well!

oh actually its not
feral field
The last one ?
dusty gyro
looks like its from the IES
yeah
hmm
not sure I still have that IES viewer installed
dusty gyro
using the IES intensity ?
feral field
Nope
dusty gyro
looks like you have the right shape
dusty gyro
how much time did it take for that scene with CPULM ?

1 hour

and some minutes over
haha yeah!
I feel so unafraid now to drag up lightmass density
dusty gyro
production quality level
this is my goto settings
lightmap density between green and red
dusty gyro
only 2 bounces for your indirect lighting ? :p
feral field
Hahha as said I had a 1 hour build time
with 10 on indirect it just got 20 seconds longer omg
feral field
Looks great!

bit too bright even at 0.5 IES intensity 😅
love this

Hello all. Why i have this sharp edges after light bake. Lightmap res 2048, textures res 4096. (left before bake, right - after bake). Here i use directional light + spot light
solemn hawk
@signal oar try increasing your indirect light quality under world settings, also make sure that you’re on production quality bake instead of preview
signal oar
I changed lighting quality at 6 and doesnt work well again.
potent forge
Has anyone tested v-ray lightbake?
feral field
This is not a archviz project, but I guess right channel to ask about lighting for.. https://gyazo.com/27802f7c7d7a2eeab9c0309a90a570c4 What is causing this light leaks on the edges here ?
feral field
I pumped up the lightmass a bit, and it fixed it, follow up question, does pumping up lightmass res a bit affect gameplay, beside build times ?
dusty gyro
@feral field unless you use very high resolution lightmaps, nah it only affects light build times, not gameplay performance
and by very high I mean 2048 and up
its an heresy to go over 1024 most of the time
feral field
@dusty gyro Thanks man! Luckily it was just a little jump from 64 to 128
dusty gyro
all fine then 😉
feral field
So I have my personal game on UE 4.21 with GPULightmass, aswell my Archviz projects, is gpulightmass not recommended when making games, will affect how to the game plays out when packaged ?
dusty gyro
@feral field GPU lightmass doesnt impact performance at all compared to the OG lightmass
think of it as a drawing
CPULM is an okay ish artist, but very slow to finish his work
GPULM is a very good artist, and finishes drawings really fast
they use the same kind of paper, and the same kind of pencils
just that it looks better in the end with GPULM
feral field
Thanks again man! But what about an AMD user that is going to play a packaged version ?
dusty gyro
doesnt matter either
once its baked its baked
textures work on all kind of hardware
only the dev will require an Nvidia GPU

@dusty gyro You are a life saver ❤

So is archviz visual artist jobs not sure if there is somewhat a offical name for it, mostly for architects ?
dusty gyro
@feral field architects are supposed to do that job but
feral field
Ahh I see, I should jump back to more game envoirments, even though I enjoy visualizing in interiors in UE4 😅
dusty gyro
its kinda of a tight spot
I've been searchin for that kind of job too for the last couple years
feral field
Yeah I personally never looked for a job in it, but its a enjoyable thing to do regardless as a side thing

@feral field A fair amount of ArchViz work doesn't come directly from architects, but also property developers or agencies who want to use it for planning permission or marketing materials

anyone here done enterprise arch viz work for Vive? has any of the feedback been that the scale seemed slightly off?
like, when the building/room was built in reality, it seemed larger than in VR?
dusty gyro
@dusky marsh not really
it all depends on how you configure the vive
and the users's IPD too
with the same IPD settings, your users might have different experiences with scale
dusky marsh
mhm. ok... well, time to get a headset that automatically adjusts for IPD then
dusty gyro
good luck finding one 😂
dusky marsh
there is at least one. but I think NDA might prevent me from saying more
feral field
Hey I am making Archviz for vive not quite enterprise, but a issue I had with my vive, was not really through unreal, but make sure the vive is on the right height setup through the steam vr
@dusky marsh It silly, but that was my problem for a while haha
dusky marsh
we use this for floor height adjustment: https://github.com/Xavr0k/ChaperoneTweak/releases

@dusky marsh for your question about instances on the forum
its a hierarchy thing as far as I remember
whats your mesh hierarchy in max ?
dusky marsh
flat
dusty gyro
check this out
something's up with that mesh if your hierarchy is flat then
custom pivots might be the problem
dusky marsh
hmm... forest pack must generate custom pivots... ugh
dusky marsh
oh, they don't. I must instanciate before I export
dusty gyro
yeah
dusky marsh
but the instances look completely fine in max... but somehow, datasmith doesn't like them apparently
dusty gyro
couple replace/instance scripts in max and it should be fine
yeah 😅
as mentioned in the studiohelp page, its a workaround to preserve custom pivots
dusky marsh
I'm beginning to like Unity more and more for every day with Unreal 😛
dusty gyro
heh, thats the other way for me 😅
do report this on https://unrealstudiohelp.epicgames.com though
dusky marsh
yes, because I just discovered that my other set of forest pack objects don't have this stupid white ball
and they're created in the same way
dusky marsh
updated the thread with that we found
dusty gyro
👌

Hello, can a scene built with Box Brushes be photorealistic in Unreal? Because my scene built with Box Brushes seem cartoonish, i can't figure how to make it photorealistic
ionic river
Do you mean like using the box brush then converting it to a static mesh or leaving it as a box brush?
buoyant hedge
converting it to static mesh
not leaving it as box brush anymore
Hello, I have this scene which look like this. From here, I make some changes, deleting the skylight, deleting the Directional Light, and then rebuilding the lighting, however everything remains the same! Where is the lighting coming from?
Self illumination? Can someone help me solve this puzzle?
OHHHH i found it. its the post process volume
inland echo
I'm trying to use a HDRI to light up a scene but for some reason It's not allowing me..
I thought unreal allowed .exr. I need to convert to .hdr?

Will Lous Gpulm 4.21 work on 4.21.1 ?
feral field
Great! I updated to 4.21.1 and for some reason gpulm was gone
dusty gyro
yeah the 4.21.1 update replaced it with the OG lightmass
mystic lynx
anyone know if you can use datasmith with a custom UE4 source version?
