What's the correct way to create a panoramic backdrop for archviz project?
sweet fossil
@drifting drift Well you should always setup UVs in 3ds Max, just make sure that if you have any fancy material or shader effects like you said, those will need re-created in UE4. Tri-Planar mapping just happens to be a very common one so easy to find resources on that specifically.
What's the correct way to create a panoramic backdrop for archviz project?
@tribal gyro Use the HDRI Backdrop actor

man, I cannot figure out how to scale my structures for unreal. I exported the mannequin so that I have a reference in 3ds max. I setup the units to cm so it's consistent with unreal. But when I import into unreal, it's a lot larger. I ejected and saw that the player character (fps default) is slightly higher than the standard mannequin.

@boreal meadow I'm pretty sure that's an artifact of Unreal using bilinear filtering for lightmaps instead of bicubic filtering. Here is a comparison screenshot from Bakery plugin for Unity showcasing the difference it can make:

@drifting drift I wouln't use manequins for measuring, just make a 1m cube in unreal and a one 1m cube in Max as part of your mesh and see if they match.

Hi guys, My name is Sujayanto, and currently I am really stuck and cannot move any further with a problem. My workflow is Blender (modelling), Quixel Mixer (Texturing), unreal assembly and lighting. Is it correct? The main problem that I am facing for almost 2 weeks with no progress is this. I have tried to uv map a simple cube room with glass on 1 side. I put it on 0-1 space. I export as fbx. send it to quixel mixer and then bam. the resolution is really bad. the line is not crisp. I have tried playing with the uv texture and it bear no fruit. can anyone help me?
thanks in advance
Here's what I get..

@royal osprey thanks dann I'll try it out
although I fixed the scale issue mostly after 9 hours lol
royal osprey
one unexpected thing that works well for scale is to view your place in VR
you will immediatly notice if things are too big or too small (specially furniture)
tribal gyro
Is there a way to change ArchvizCharacter walk speed??
austere hazel
@golden cliff were you able to fix your issue? If not I usually don’t map big objects in the 0-1 uv space, instead I just use uvw (or triplanar) mapping and then slap on a tileable texture from quixel bridge. Otherwise you either have to use a huge texture or break up the surface into smaller pieces. Per object textures are good for smaller assets (chairs, books, tables,....)

Anyone knows how to use GPU lightmass in 4.25 ?

Hi! Let's see if someone can help me or give me some advice on that. I'm developing VR archviz and my client would like to show that projects with a webbrowser (Just 360 images not in VR). I've been investigating and I found some platforms used to do 360 panoramas. Would you think that this could be a good aproach? Some examples: Kuula, Kolor PanoTour ...
signal frigate
You can get 360 captures from ue4 using a plugin, ansel i think it was.
You want to have waypoints and move from one 360 to another?
You have a few Wordpress plugins for that, also just for presentiing single 360
broken radish
Thanks @signal frigate For the moment I'm exporting the 360 panoramas with scene capture cube, is it better to use that plugin?
signal frigate
It probably has more options but scenę capture should be fine.
broken radish
I have red that I could do my own visualizer with javascript. I know a little bit of code so I will give a try on that. It would be very nice to use several 360 images and connect them like google street view does
signal frigate
But its complicated to use and install. But worth if you want like 360 3D and lot more.
broken radish
Ansel plugin is that that works directly with nvidia

hello, i need some help on creating master material and function node for object using multi material ( but not element, just 1 texture with B&W mask for each ).
For exemple, 1 big wall with alot of plastic, metal, fabric,.. panel, all type of material on it, and i render front view to get the diffuse filter and render ID for masking each of them.
now in ue4, i want to add a whole bunch of adjustment node ( power, multiply, desacturation, Hue, Blend dirt,... ) for Each mask in my master material. they all come with different parametter value and boom, a tons of parametter in instance and that doesnt look good for editting.
for now i can only do 2 or 3 mask in 1 single texture, because i only know the "If" and "static switch" and few other node for option chosing. if i have more than 3 mask, i dont know how to work with them.
how would you do it as game dev. is there some kind of function note and attribute node where i can just call it out in instance for each mask layer, like if i have 4 mask, i call out 4, 5 call 5,... and does not depend on how i setup master.
Thanks in advance

Had some fun pusing my pipeline speed in a week with this project :)
tribal gyro
Why is this? High bake + the lightmaps are quite dense
royal osprey
@tribal gyro it's not a lightmap density issue it's a samples issue, you either need more samples or you are trying to correct a very dark lighmap with auto exposure.
tribal gyro
samples as in indirect bounces? @royal osprey
royal osprey
default unreal lightmas or GPU lightmass?
in the default engine, samples are hidden in the settings (level scale and indirect lighting quality)
tribal gyro
default
ue4 has a GPU lightmass?
in the default engine, samples are hidden in the settings (level scale and indirect lighting quality)
@royal osprey Those are already set quite high
royal osprey
yes, you have to download it and install it
if you have a good gpu it's way faster than CPU
if those settings are high, then it could be the other possibility I mentioned in my first response, how does that look with autoexposure min, max at 1?
tribal gyro
It's currently set min and max 1
I try to work as clean as possible when it comes to lighting. no exposure compensation and stuff
tbh nvm i've thrown a spot light there we'll see if that fixes the issue
tribal gyro
royal osprey
Your settings are ok for most scenes. Scenes that suffer the most is when there is a lot of contrast. Like very bright but small windows or polygons in an otherwise dark scene.
tribal gyro
ill look into it thanks
boreal meadow
i'm still stuck in those jagged shadows. I have no idea what is the problem. lightmap resolution is high for all the objects, compress lightmaps turned off(tried with him on as well)...
tried changing the lightmap detail cell and the result is still the same too
on the render is visible that not all shadow edges are like this so it's even more weird to me...
royal osprey
the lightmap resolution is not as important as the density, how does the density look?
boreal meadow
@royal osprey thanks for the reply. When you say density, did you mean this?
royal osprey
you could use more on the green stuff and less on the red stuff
basically size those things in your UV
or if they are separate objects give the floor more res
boreal meadow
oh, ok i will try, lets see how it goes 😀
@royal osprey it worked! Thank you! You're awesome!!!!! 👍
true prairie
Hey guys! How are you
ooh
@boreal meadow Dont take what I will say as a fixed ruled but for Archviz, you would generally tend to increase lightmap resolution until everything is red. ( BTW, object will get red when lightmap resolution reaches a texel density of 0.80) There will be cases and objects in which increasing lightmap resolution so much maybe won't be needed though. Also take into account that increasing lightmap density will increase baking times. But in archviz we usually aim for very high lighting quality standards, so...
i'm still stuck in those jagged shadows. I have no idea what is the problem. lightmap resolution is high for all the objects, compress lightmaps turned off(tried with him on as well)...
@boreal meadow Btw, you said that lfloor's lightmap resolution is already high. The thing is that you may prefer to divide that floor into several smaller parts so that you can decrease their lightmap resolution. That strategy usually leads to much lower baking times, that's why you will find so many people that divide their models in very small pieces. It's a better workflow than increasing a unified floor's lightmap resolution to very high values.
boreal meadow
@true prairie i see! Thank you for your notes! Splitting the floor(or any object) into more parts also helped! Really appreciate the help!

Correct way to set up urban hdr
not hdr really, I have a panoramic backdrop of a city I need to put around my environment
Right now I have it mapped to a cylinder but the caps are visible.
pale prairie
@boreal meadow you need to change your static lighting scale and indirect lighting quality
for example static scale: 0.5 and quality: 2
lower number for scale is higher quality, higher number for quality is higher quality
good trick is that they should multiply together to = 1
also click the drop down next to build and change lighting build quality to medium or high
its on preview by default
boreal meadow
@tribal gyro thanks for the reply man. But i'm using gpulightmass... Does static scale and quality change anything using it?

Running into an “out of memory” error using gpu lightmass on ue4.24. It’s a small flat and I’m not done detailing it yet. Most of my lightmap resolutions are in the reddish zone, some are green. How do I fix it? Gtx1080 and 16GB DDR ram. Is this common or is there something very wrong with my scene?
hallow arrow
it is out of VRAM instead cpu ram.
you cant fix the problem without lowering lightmap resolutions and scene complexity now
the new GPU Lightmass in 4.26 will be much better at handling VRAM, though it requires ray tracing
austere hazel
Thanks. I’m considering getting an rtx3080 and start working with raytrace only, am I correct in assuming that scene complexity won’t matter that much with raytace?
hallow arrow
4.26 will be out very soon. you can try to hear from other ppl who have something like a 2080Ti about their experience in scenes with different scales
royal osprey
I have a 2070 and I have yet to get that error, but I optimize my UVs a lot
Are we getting any kind of auto texel density tool? I know there is an addon for it, just wondering if there was one planned in house.
idle mulch
Hi !, quick question if anyone had a similar problem. I cant install gpu light mass for 4.25, or rather I'm installing but its like nothing is happening. And I believe I am putting them to the correct file path I don't think that's the issue. Does anyone have an idea of what might be happening ? I have rtx 2060 gpu and ryzen 5 2500X cpu. I did a render with cpu and the temperature hit 95 degrees Celsius, so i don't believe its a good idea to continue calculating with cpu😆
vernal pecan
@austere hazel @hallow arrow is right, we've been using GPULM internally on some pretty massive (we're talking gigantic hotel complexes) without any memory issues.
austere hazel
Any pointers on how one would debug this? Other than checking lightmass resolution I wouldn’t know where ro start. Was your massive hotel an interior and exterior project?
austere hazel
I tried splitting up the biggest surfaces in my scene and it doesn't crash now, so to me it looks like more smaller meshes is better than fewer bug bigger, am I right in this assumption?
tribal gyro
Hi! If you were tasked with creating a huge residence area archviz project, with several buildings, each building has various apartments you can visit. So the project has exteriors and interiors. How would you approach that level streaming process? Using sublevels with Lvl Streaming Volumes? Perhaps each interior loads a whole different level without sublevel streaming? I need ideas. Thanks!
royal osprey
I'm assuming this is for real-time, not a video. Unreal has occlusion culling on by default, so if performance or memory consumption is your concern, all you need to do is to make sure things are individual assets. (Don't have all the couches from all the rooms in the same static mesh, it's a weird thing to do but I've seen things like this).
tribal gyro
@royal osprey That's the issue mostly yes. (real time project ofc). Are you sure it culls everything that isn't visible tho?
Having imported the scene from Revit via Datasmith, I have 3 buildings and when I look at them all the FPS goes very low
royal osprey
it culls what it can't see
tribal gyro
I was thinking using LVL streaming to destroy the outside once I enter a building and vice versa, destroy all the interiors when im outside
royal osprey
that is the default behaviour, but things need to be made into units for this to happen
royal osprey
well.. yes and no
tribal gyro
More different meshes= more draw calls, but better culling
royal osprey
you can also slow it down if there are too many pieces, but don't group pieces that are far apart
tribal gyro
Yeah I see
Think that'll do it without ever touching lvl streaming stuff?
I mean the project is pretty huge
royal osprey
there are other things you can do to oplimize it
like using a a set of 3 or 4 master materials and have instances of that for every material. Reuse the same materials as much as possible to reduce draw calls, and of course decimate/reduce the geometry wherever you can.
royal osprey
gl
tribal gyro
@royal osprey using stat scenerendering I can see that mesh drawcall number is huge and performance is slow when looking in the direction of the meshes even when theyre not visible, behind a wall or something
So unreal doesn't really cull them after all
tribal gyro
what do u mean?
tribal gyro
Well, it does occlude what's not visible but the performance is still aweful
when looking in their direction
royal osprey
it's not rendering it, but it still has to constantly check if it's there
tribal gyro
So might aswell destroy it with level streaming don't you think?
royal osprey
some experimentation is in order..
tribal gyro
thanks for ur time

Hi, I would like to make a change of lights similar to this effect: https://www.youtube.com/watch?v=amRDYrLHwpI&ab_channel=MoodLightTV
Do you know of any tutorial or how to do it?
I do it with emissive material. How do I set the timing? And above all, how can I make a single transmitter change in this way from right to left
steep shale
do you literally want a full screen of color? because there are easier ways than unreal engine if so... it's about 4 lines of javascript to do it in a webpage.
atomic ether
Nono, it must be in unreal because it goes together to an interactive 3d space. Reference step
steep shale
First, give your material a color parameter, and then in a blueprint that uses the material, you can do something like this:
this is just a random example, tweak the math for the color as you like.
this is the material setup
nothing complex here.
you could add a parameter to multiply the angle by something before the sin/cos to change the speed of the effect
This is the resulting effect of the above...
I did this on the basic shape material out of laziness.. you'd modify whatever material you want to morph colors your scene instead and the blueprint for the actor that you used to place the thing in your scene.
atomic ether
If this material were applied to a long object like a rectangle, if I add the angle, does it represent that it will change from one side to the other gradually?
I have sent that wetransfer so that you can see a video (it weighs a little) of more or less the effect.
It does not have a virus or anything, but if you want to check it or tell me a better way to send it that is more comfortable
steep shale
no.. you need to do something different if you want a long object to have a gradually changing color along the axis.
but that's really just a minor change to the material itself... the rest of the logic is the same
sorry, i don't want to register for the service hosting your download, so i can't reference that, but let me see if i can tweak the material to do what i think you want in the shader.
atomic ether
No need to register, if you look at it, you can download automatically, I will also cut the video to show it here
steep shale
i'm trying to move all the logic to the texture itself now.. this could take some time, but it will probably be more efficient runtime.
(i mean the material actually)
atomic ether
I get it. Thank you very much for taking all this trouble.
You really help me a lot and I hope I can help you one day
steep shale
basically what you want to do is take the position in the material as an input to the color chosen...
eventually you'll have a rainbow material, and then you'll offset the starting point over time, and it will appear to animate.
Unfortunately i am new to the language of unreal engine.. i know how to do this in GLSL.
atomic ether
Go ... see if someone can give us a hand
royal osprey
I would use a panner node, moving a hue texture in a uv that is tiled to be really big (so a 0.1 in the tile setting)
atomic ether
@royal osprey That I have been told in other forums. Make use of the UV, however I do not know how to do it or how it would look, any video that you know on the internet that can help this?
timber sun
Hi, Quick question what is the best way to move the datasmith import coordinates so it aligns with the world objects so it can keep relinking properly as you progress the model? I'm off in the middle of nowhere
I'm very new
atomic ether
For @timber sun
It depends from which program you are exporting and importing from datasmith but if you work on the 0,0,0 axis with the pivot, in Unreal it should take the exact reference
timber sun
So move it in 3dsmax/Sketchup versus inside Unreal?
atomic ether
In both sketchup and 3dsmax the pivot has to be in the center. In any case, if you work with Sketchup, I would first send it to Max to correct errors
royal osprey
@atomic ether Not for your need exactly. But UVs can be scaled by multiplying them to make them bigger or smaller and they start to tile, the panner node can be used to move the texture along the UV so it appears to change color.
atomic ether
For @royal osprey
I think I understand but, you have no example of how it would be true? I'm something new even in Unreal and I'm lost.
royal osprey
no sorry and I can't make it now, rendering.
atomic ether
OKey! Thks!
royal osprey
This is the panner node, imagine instead of bricks a HUGE texture that has all the colors fading to another, like a horizontal color wheel. https://www.youtube.com/watch?v=24mfLY7aQFQ
of course the texture doesn't have to be huge, just made huge by tyling the uv (making the uv smal makes the image big.. )
atomic ether
Yes I understand! I think it is the best solution we can find right now!
thank you so much!
steep shale
@atomic ether
This works.
all by itself.
Here's what the material above looks like now...
you can change the multipliers i used.. or transform and rotate the coordinates for different effect directions (like on a diagonal or whatever)
at any rate, this should run completely inside the gpu.
atomic ether
Buah! Great! Thank you very much!!!!
steep shale
the advantage of this vs panning textures is that the movement of the color shift is coordinated throughout the scene.
so it will appear to go from one object to the next if they're placed in a line.
For example...
i didn't know i needed this material until you asked how it was done, but i'm glad i made it. I'm going to get a ton of use out of this.
steep shale
@atomic ether I tweaked it a bit: https://youtu.be/2WUgb6Q9h30 this is more interesting to me because the colors have contrary motion and there are variables now to change the scaling and speed.

atomic ether
Don't worry, if you want, I'll give you the 3D scene already ready to export in case it makes you fun
steep shale
nah it's more fun to figure out how to do it myself, because i usually learn something trying to replicate things others have done.
steep shale
For example, just now importing my mesh from blender, i learned that it doesn't know the inside from outside:
steep shale
should have just made it out of cubes and then i wouldn't have an inside vs outside issue.

Im releasing my project files from a recent project I did over on my artstation store.

The assets have custom made lightmaps and uv's. This is great for training lighting skills in UE4, as there is no extra work needed to prepare the assets.

Hey guys,
I am using Datasmith in order to import models from Sketchup and then replace the textures added in sketchup with Quixel Bridge textures. Works fine for big surfaces, however the smaller 'group' at the right side has this super tiny texture tiling. How can I make that consistent or bigger?
Thanks in advance.
this is how it came from Sketchup (datasmith) after importing...

Modify the material to use tri-planar mapping (world aligned texture)

Im doing it exactly like in the Unreal course "Creating an Architectural Exterior Real-Time Project" and in his video it lights up the scene with an intensity of 1-2
When i try that, with that same HDRI, first of all its not intensity for me its cd/m² so clearly theyve changed it between verions, and i need to set it to like 50k and even then its a blodgy grey mass, not much of a light
and i cant get the bp_skysphere from the engine content to work with the sunsky object, ive created multipe new projects with and without Raytracingand the sky wont react at all to the sunsky object like it used to

@tribal gyro if you go into the world settings, find the lighting level scale option under lightmass settings and turn it down. the lower it is the greater the build times... much greater. also you might want to check on your light maps as well
make sure the resolution is small enough so that the meshes have enough information to shade smoothly
hey gang, does anyone know why im getting terrible shadows on my landscape? they look very blobby and inconsistent.
I assume it has something to do with the lightmap res?
the problem is that I need the directional light to be stationary so I can get baked GI but dynamic shadows on movable objects for my interior.

Hi group. Novice to intermediate UE4 user. My focus is almost 100% photorealistic cinematics.
Can anyone recommend a really good test scene in the Marketplace for testing lighting, especially ray tracing?
fleet flame
Hello everyone i m bit new to arch viz but i made a test scene where i wanted to test real time lighting and no ray tracing. The thing is i want to make day and night cycle in a scene. I made also to be able to turn on/off lights and open doors in my scene.
I would like some opinions about the lighting mostly.
Here is a download of my baked project its 1Gb download and 2.6Gb unziped

Anyone figured out how to stop ray tracing translucency causing flashing?

@bigalek
you need more indirect lighting for better shadows. you could try hard baking with the sun dynamic but separating the scene into levels for a day and night scene.
fleet flame
No man i will stick to real time, baked is easier to get better results i know that just i need it in real time. Thx for the feedback 😉

Does anybody have experience with Octane for unreal?
i'm having problems with the camera where octane rendered images have a different angle or sensor width than what unreal renders.
But its correctly implemented as far as i can tell
median summit
Who here is using raytracing? Have enabled RayTracing, set default RHI to DX12 and enabled several RayTracing features in my Post Process Volume.
My noob question is how do you actually view changes to your settings? Is a 'Build' necessary or by default should any changes to settings be reflected in your viewport in real-time?
royal osprey
@median summit you can see it in realtime if you have the correct settings and hardware.
paper crest
https://youtu.be/BEBEiNJ875g Here is a clip form a current work in progress. I thought I might interest some of you as Its the first project I have done using full ray tracing, no baked anything, no reflection captures. All GI, Reflections, translucency is ray traced, all screen space effects were disabled. Its done using 4.26 preview and an RTX 2070. I am really impressed by the improvements to the final gather GI in 4.26. It seems much better than 4.25. The video was rendered out using brute force GI with 4 bounces. Its very exciting to see how quickly this is being improved and perfected by Epic.
median summit
@royal osprey ok thanks!
mellow crater
@paper crest that is beautiful!
median summit
@paper crest thanks for posting. Is there a reference somewhere documenting Raytracing improvements in 4.26? I assume since you were using Brute Force you were not rendering in real-time. Would love to see a render using Final gather.
Have any RayTracing experts tried to create caustics effects from reflected or refracted water or glass materials?
Is this even possible using the official release of UE4.25? Or is it necessary to compile an experimental version from Nvidia? https://news.developer.nvidia.com/caustics-available-this-week-on-experimental-nvidia-branch-of-unreal-engine-4/
paper crest
Here is a comparison of Final Gather vs Brute force. You can see the brute force has better secondary bounce lighting
@median summit
The first image is brute force, the lower one is final gather
Check out the above video on for info on advanced ray tracing features that are available in the nvidia branch
My project will be a realtime VR project but I am using the brute force rendering for the still images and video that are part of the package. The VR project will have everything baked for performance.
median summit
@paper crest Thanks for posting! Have you been able to access the Nvidia branch? I keep getting a 404 even after linking my github. This is what I am hyped about https://www.youtube.com/watch?v=ZefvmV1pdP8&t=6900s

Once I go Lit it's invisible. Any ideas?

Seems like there is no point in baking shadows of one can generate high quality renderings with raytrace
What about the vray baker? Is it any better than the examples above?
Beautiful render @paper crest
paper crest
If you can afford a fast RTX card and you dont need to run it in VR then I dont see the need to bake GI anymore either for these kinds of projects. My rtx 2070 is not really fast enough to run scenes like this at high resolution, I only get around 20fps at 1080p when using final gather and it drops down to 4-6 fps for brute force. I cant wait to upgrade to a 3080. The last time I tried Vray for Unreal it was crashing on me a lot so I gave up. The new GPU baker that is included in 4.26 is the next thing I'll be trying. It looks great in my initial tests and other people are getting some amazing results with it.
real niche
Anyone here using blender?
I'm modelling a door but I'm not sure how it translates to unreal.
Are the dimensions here accurate in unreal engine?
royal osprey
@paper crest the new GPU baker is pretty cool but it had a limit of 256 lights last I tried, so it was a no go for me (I'm doing something huge)
@real niche the dimentions should be fine in Unreal

Alright thanks
royal osprey
@real niche enable back-face culling in Blender, just to make sure your normals are pointing the correct way.

Hi, I'm trying out the UE4-NvRTX build by Nvidia. It was said in the documents that emissive surfaces are supposed to behave like lights. However, emissive surfaces don't seem to be casting shadows. Does anyone know anything about this?

@whole yacht that must've taken you ten... hours?

Do you guys recommend using the HDRI Backdrop plugin? I'm a little confused about how it works.. do I delete the sky light that is already in the scene by default?

@tacit tapir no actually just 1hr😅
@wicked willow depends on wat you want to do. Keep the sky lights light but set it to movable and mess around with it’s settings till its satisfying to u
tribal gyro
Having a big exterior scene with 13 buildings. performance is pretty bad when looking in the direction of all of them. Also baking times are too long. What are some way to optimize this? What do urban levels in games do?
what about culling distance volumes?
steep ridge
I'm having trouble. I have a SunSky along with two DatasmithArea lights infront of windows, but the SunSky always seems to blow out the scene. Just where is the light component that AreaLight creates, is it not in the details panel?
steep ridge
Another thing, There is a Box Reflection Capture in the ArchViz Interior Learning project, but no static lights? What's the point? Raster reflections are completely black except for the sky light through the window. Is that intentional?
serene moon
i cant seem to get the volumetric light map to give me anything information when i enable it in the visualize tab..... ive baked mylighting , even adjusted in the world settings... but nothing! I have included light mass importance volumes and LightmassCharacterIndirectDetailVolumes, is this visualiyer broken in 4.25.3?
is there something in the project settings that i must enable?
ive even placed volumetric lightmap density volumes... im running out of ideas... super annoying

@paper crest do you have dlss

@mellow crater nope, I haven't downloaded the nvidia branch yet. I read that other people were not being granted access to dlss so I didnt bother. It would be a massive help if it was available. I'm just going to upgrade my GPU to a 30 series as soon as I can get my hands on one.

Is there a way to import a scene from Blender, but keep relative locations ?
I tried usind blender to unreal add-on but the objects dont keep location
lucid orbit
there are several blender to unreal addons
have you tried official one? (on github) @naive spruce
lucid orbit
to be honest, I have yet to figure out how to export multiple meshes like that, but no success so far. I had fuzzy thought there's addon that lets export meshes to ue4 placing them in world properly, while keeping object origin. Maybe that was just future feature of some addon. The one I'm using is called blender to unreal engine, has a lot of options, but no solution there either, it can either move meshes to zero world origin (scene/fbx) or keep meshes in world position, but object origins are in zero origin sadly @naive spruce

Hey there,
Did anybody else experience color shifts when using raytraced Transluceny:
I'm attaching two examples of my scene, one is grass with raytraced translucency the other is rasterized.
I've already tried messing with the grassmaterial to get rid of the redness, but it didn't help.
Any ideas?
in the upper one you can see a lot of red. Gets worse if you look at it from inside, through glass....
wicked willow
Working with reflection cubes ... What is the correct way to fix this? If you look at the floor you can see these rectangular patches that correspond with the size of the reflection cubes I created
here's how they look in the top view
royal osprey
you should have one that covers everything, then smaller ones
wicked willow
@royal osprey ok that did help they are a little less than before but still noticeble
what about this difference here ? the box transition distance?
i already increased it hoping it would produce a more gradual falloff
royal osprey
hmm no idea, are you sure it's not just a shadow?
wicked willow
I don't think so . I switched to Box Reflection because when I used Sphere Reflection I was getting a similar circular border at the edges of the rooms. When tried to make the sphere radius bigger than the room to get rid of it I was getting reflection of items in the adjacent rooms?
but I didn't know about making one giant reflection capture to cover the whole area. maybe that could fix the problem with the sphere captures..

merry patrol
Can anyone help me guess at two why I'm getting these pixelated shadows?
I tried scaling up the light mass resolution, which I assume is the 1024 in the screenshot. Scaling to 2048 changes nothing.
A note of importance, - I constructed the walls as one giant mesh, and scaled the UV's up in blender past their bounds. Not sure if that causes problems.
pale prairie
i think you mean lightmap resolution
can you send a screenshot of your lightmass settings?
merry patrol
I haven't changed them, they'll all default
Yes, light map resolution. not light mass. I'm not sure what lightmass is, exactly.
merry patrol
I'm having bizarre issues where the lighting starts dark, but fades into brightness
pale prairie
lightmass settings are essentially the paremeters that control the quality of your lighting
the reason your lighting is low quality is because the default settings are very modest
also i imagine you are building your lighting in preview mode
merry patrol
The screenshot was production mode
pale prairie
ah ok
high is fine until your finaal build
production has a significant build time increase for a very small quality gain
merry patrol
I can't seem to be able to control the lighting in ways I want to. I get light leaks in the corners of the wall, artifacts, and I can't manage complete darkness in certain areas
pale prairie
yep that has to do with your the low sample count from default lightmass settings
try static lighting level scale 0.5
num indirect light bounce 10 as well as for sky indirect bounce
indirect lighting quality 3
and smoothness 0.9
also disable compression
you should see huge lighting improvements
you can scale them up from there to fit your needs
pale prairie
yeep
merry patrol
Let's see what I get on high quality
pale prairie
you can always try GPU lightmass for vastly faster lighting build times
depending on your graphics card
merry patrol
GTX 1070
pale prairie
yeah should be solid for gpu lightmass
merry patrol
Where's the option for GPU? Seeing as my build time won't move past 0%
pale prairie
Im pretty sure its a plugin that you enable
but the builds normally sit at 0% for awhile before going up faster
its normal behavior
merry patrol
Those settings didn't help the walls much
pale prairie
did the build finish?
merry patrol
merry patrol
I think that may be the problem
The walls aren't modular
They're one giant mesh
I scaled the hell out of the UV map
pale prairie
yep
i mean density looks good to me
floor and ceiling are low
but everything else seems fine
merry patrol
Strangely the floor and ceiling don't have artifacts
pale prairie
odd
pale prairie
I don't know if you did this but you need unwrapped UV's on your 2nd UV channel for unreal engine lightmaps
merry patrol
I managed to get away without doing that for other objects. I assumed unreal makes a new channel automatically for lightmaps
pale prairie
yeah I think unreal engine is pretty good about auto generating lightmap uvs from your channel 0 UV's now
merry patrol
I think you're right about the bad 0 channel
hollow canopy
yeah I think unreal engine is pretty good about auto generating lightmap uvs from your channel 0 UV's now
@pale prairie doesn’t unreal generate a light map from whatever channel you specify as light map source?
Say you have a UV for textures on 0 and light map on 1, then setting source to 1 should result with UE generating bakes from 1 to 2(default)?
Just wondering if one should use the same destination index as the source or separate them. In my head setting them as the same would override the source wouldn’t it?
royal osprey
if you created a good lighmap UV while modeling then at import untick "generalte lightmap UV" and it should automatically use the one on chanel 1 for baking (channel 0 for texturing) If you didn't untick that it will generate a third channel, from what channel you have as source and assign that for lighmap.
hollow canopy
Right. So if I carry over a light map from blender in ch1 and set destination to 2, then all should work as expected, yes?
royal osprey
not sure what you are expecting 🙂
hollow canopy
Well I was just trying to wrap my head around whether the destination index denotes the space where a light map is baked to - meaning whatever was there previously is replaced with the baked map during light baking. So Unreal docs mention that if you’re using index 1 from auto generated, then your destination index should ideally be 1 as well. To my mind - it sounds like baking would replace that? Or are those two separate things?
That’s sort of what I’m trying to understand.
royal osprey
there are two common workflows.
- have only the textue UV, then have Unreal generat the lighmap UV from that. (so it should be source lighmpap index 0, destination 1)
- make both UVs in 3d app, and untick "generate lightmap UVs"
In some cases you might have more than one texture UV, (sometimes you need more than one for texturing reasons) so in that case you would have to select a different source and destination depending on what UV you want as source.
hollow canopy
I see. So basically the destination should be above whatever index number that is your last UV used for texturing.
Gotcha. Thanks!
royal osprey
you really don't have to touch the defaults unless you have more than 2 texture UVs or for some reason Unreal screwed up. by default it's set as 0 for source 1 for destination. And by default if you untick generation it will use 0 for texture 1 for LM
hollow canopy
No I got that. I was just asking for my own education and so I understand it more. What I do now is pretty much the same - I import meshes with texture UVs at 0 and LM on 1, and just use it that way. What slightly threw me was the destination index and it’s purpose and whether it overwrites anything.
royal osprey
about the overwriting I'd have to test
but I've never experienced it, since the defaults are pretty smart usually.
well acording to the documentation, it does overwrite
if you select the destination to be the same as source.
so you can change the padding and pack it better if it was poorly packed.
hollow canopy
Understood. So, useful for re-generating a light map
steep ridge
Since we're talking LM. I'll repost my question from #datasmith :
"every time Datasmith imports a geometry object from 3ds Max into a Static Mesh Asset in the Unreal Engine, it uses two UV channels to generate the lightmap UVs for that Static Mesh"
Two? What are they talking about?
rose comet
@steep ridge Think they just mean there is one for normal textures and second one for generating light maps
steep ridge
@rose comet, thanks for replying. I don't think that's the case because:
"This results in a set of UV channels numbered 0-4 in Unreal. Finally, the import process creates two additional UV channels, 5 and 6 in this case, for the auto-generated lightmaps."
They explicitly say it adds two channels, and I've never seen it do that. If I import an object with 3, I'll get 0-2 plus '3' auto generated. Is it outdated docs?
This has been really bothering because of a bug where I couldn't set the Lightmap Index to greater than '3' on a model exported with four UVs.
hollow canopy
I’ve never see more than one
boreal meadow
Why does this happen to my models when i import to unreal? on 3ds max using v-ray it does not have that issue... 😟
royal osprey
If you have a normal map, try inverting the green channel. some apps read it different than others.@boreal meadow
tribal gyro
My shadows are always jagged. no matter the lightmap density, bake quality or world settings. How can I fix that?
mellow crater
proprty of the light actor
tribal gyro
u sure?
royal osprey
are you sure that light is static?
tribal gyro
yeah
tribal gyro
Apparently it was all too low texel density on those areas
I always find I need to bump the lightmap resolutions higher towards the red area to get nice crisp shadows.
royal osprey
it depends on the material, but yeah
shinny stuff, dark stuff, stuff with textures with variation, look good lower than red.
tribal gyro
Optimal FOV for Archviz?
rose comet
Depends if it is a beauty shot or client wants good overview of the scene... I'd say 45-80 are "safe" values. I usually use around 60 for 80% of the work.
royal osprey
"what looks good" I fiddle around with it a lot depending on the shot. A bit wider shots for interiors than exteriors. Having said that what Gorr mentioned also applies, a beauty shot will usually be a tighter shot, (the typical rack focus transition from a foreground item to the background).
sweet fossil
anyone had this issue with datasmith assets where applying a different material breaks it? Highlighted mesh here is from a datasmith import, I've dropped my asphalt material on it and it changes to a checkerboard?
open cipher
Am I using light portals wrong? Window is a static mesh. Top is shadows disabled on the mesh, bottom is shadows enabled. If I'm understanding light portals correctly there should be four light beams coming through the window on the bottom screenshot.
drifting drift
I used UDIM workflow for the first time with max/substance/unreal. Without it, everything is fine, but with it ...
Everything is darker as well. Some walls are the colour they were supposed to be, another on the exterior has become super dark. None of this happened when not using UDIM workflow.
furthermore, the exterior walls use one texture and for some reason one wall has this yellowy tint to it but another does not. Again, only happening once I began using UDIM
it mentioned in one of the logs that lightmaps were overlapping. Since I haven't done anything with those (never set them up to begin with, so everything is being done auto by unreal), is this the culprit?
steep ridge
@sweet fossil Is it actally compiling the material? You'll probably see an error if you open the asphalt material.
steep ridge
@drifting drift I still don't understand why I'd use VTs.
sweet fossil
@steep ridge, the material is already compiled, I was using it on the other road piece there.
mellow crater
where are the shadows? nothin gthere. totally dead
what i tried:
higher light map resolution.
using a default cube from ue4 as a floor. still the skylight doesnt create shadows on the default cube (statismesh)
skylight and sun do cast shadows.
i changed lightmass settings.
and perhaps other things, don't remember.
royal osprey
is everthing static? (including the sky light)
the floor is huge, if you don't have a very very large lightmap you won't get any baked shadows.
mellow crater
@royal osprey when i use a point light the floor gets shadows. skylight doesnt. i also added the initial main text above.
royal osprey
If you have the walls separate from the floor try doing tests of only floor and block.
is that window a hole? does it have a glass? is it a separate object you can turn off shadows?
I had a problem like that once, turns out the skylight was movable..
it might be something silly like that.
mellow crater
floor and walls are one mesh. that window is just a hole, no glass.
lightmap is 2048, blue colour
standard is 64
hollow canopy
Okay, but 2048 is the setting in unreal?
hollow canopy
I’m wondering if your source lightmap UV might be small (256/512) and when unreal ups the res from the original AND has to bake onto such a large room - your shadows are THERE but are way too big to look like shadows and may just end up looking like tint.
mellow crater
o.O wait
hollow canopy
That and you really should separate floor and ceiling from the main walls at the very least
mellow crater
hollow canopy
I’ve had all sorts of issues myself with this. I’m doing an apartment for my game and I’ve had so much crap to deal with before I found the “right” thing for me
Okay when you are in that UV mode in blender, hover over the selected mesh and click U, then choose the lightmap option and tell me what resolution is shown in the dialog that opens.
hollow canopy
I’m using it and they come out near perfect
mellow crater
512
hollow canopy
Right but if your current UV or whatever you mapped in blender is actually 512, and you tell UE to use that as source, then UE would be up scaling. I’m thinking that might involve some weird stretching
Cause you are using 4 times the resolution in UE
mellow crater
where cna is ee the uv resolution in blender tho?
hollow canopy
It’s far better for you to split the floor for a test, just use lightmap pack in blender on it, choose the res as 1024, import it to UE and then raise it slightly above the existing floor so it covers it. Then change source index on the new floor to 1 and destination to 2, resolution to 1024 in UE as well (not the minimum res though) and then do a bake and see what’s different.
hollow canopy
Cause then you use blenders autogenerated UV’s and it’s not a 1:1 test
Not blenders
UE’s
mellow crater
so using ue4 cube is not good?
hollow canopy
Well isn’t it logical that if you are troubleshooting a blender mesh and blender made lightmaps in UE, that you use another comparable blender mesh as a test
Otherwise there’s no point
mellow crater
i dont understand how that is related to the default ue4 cube
hollow canopy
It isn’t that’s my point
mellow crater
huh?
hollow canopy
I would not use any UE meshes because your actual room isn’t from UE
It’s made in blender
mellow crater
ya but if the ue4 cube dosent work, then its not lightmap reoslution
hollow canopy
That’s not true
mellow crater
what how?
hollow canopy
Because I can guarantee you that I can make one cube in UE and one in Blender - both identical and make it so that the blender one has shit lightmaps and UE has good ones or vice versa.
You want help, but you don’t want to take 2 minutes to try out something that helps troubleshoot.
mellow crater
i just thought that this is a quicker way
hollow canopy
When you’re troubleshooting stuff, you can’t be taking shortcuts
Or you won’t end up solving the issue
Also make sure you recalculate your normals on the meshes if you aren’t seeing shadows, sometimes if you use the solidify modifier and screw with faces and all that - you can end up with inverted faces which will fuck up your LM’s
@mellow crater I’m gonna be on my pc in 2-3 hours or so, if you’re still having issues, I can grab the room mesh and light settings from you and test on my UE and see if I can help in a more involved way.
hollow canopy
K I’ll try it out for you when I’m home.
mellow crater
:< ok.

Hey rendering gurus
question, the ceiling had a white material. though it comes out very dark almost unlit.
it is all raytracing,
I'm working with sun and sky but i just can't get the bright indoor lit look that i want
i tried arealights and that gives me the look i want
but i want to change on the fly from daytime to night time
royal osprey
I don't see a sky light in your scene
mellow skiff
its in the sun and sky
royal osprey
oh
royal osprey
do you have your glass in a separate layer?
just to test if you can remove it and see if light comes in
mellow skiff
yaa it really difficult to get the proper look with the sund and sky thing
this is what happends when i remove the box reflection capture
mellow skiff
but then the overall scene is way to bright and all the shadows are washed out
mellow skiff
sphere or box
royal osprey
then add another one in the center of the room, smaller one
sphere is fine
make sure both are centered in the middle of the room
or near
but not on the floor, like at eye level
royal osprey
hmm
royal osprey
are they all movable?
mellow skiff
skylight all defaultsettings
yeah
but also the blue should wbounce way more
i feel like the raytracing is a bit faake in unreal
like not truly RT, like in otoy octane or Redshift
all the tuts on yt are also using area lights in the windws
royal osprey
it's all kinda new and lot's of settings to move around
mellow skiff
mabye it is just not optimized for sun and sky
royal osprey
maybe the skylight has "raytracing" disabled
mellow skiff
royal osprey
how about increasing intensity?
mellow skiff
nah it just washed out everything haha
royal osprey
I don't see raytracing in your scene
mellow skiff
imma build it fromt eh ground up
royal osprey
not in the reflections anyway
royal osprey
are you sure you have directx 12 and raytracing enabled?
royal osprey
yeah I see it, your floor is just rough
royal osprey
all my scenes are baked so I'm out of my confort zone
steep ridge
@mellow skiff try 'force no precompute lighting'? Maybe some bakes are throwing you off?
hollow canopy
Hello peeps, I have a bugbear.. I'm seeing these light bleeds on high/prod bakes, and wondered if you've got advice?
As you can see the bleeds in #1 do not correspond to sun direction in #3, and my LM and settings are in #2, I do not see issues like this in the main "decked out" room, but in empty rooms - this is happening
Close up of the bleed(??)
^ one more piece of info - the last image is detail lighting, so the reflection is from the material
I.. uh.. solved it myself.. But just for anyone in the future - box reflection captures can cause this if their bound exceed the room they're in. Additionally - they create light artefacts like so:
hollow canopy
This is a little contradictory since the general advice is to make them smaller in radius for accuracy, but that then causes these lighting conditions which is a bit weird..? Any tips on how to not let a RC fuck up my lights?
royal osprey
The workflow I use is one huge spherical that covers everything, then extra sphericals for each area, I only use box captures if there is a big flat shiny area (like a very shinny wall or even a mirror) I put a box capture right on it If I can't use planar reflections or raytracing.
hollow canopy
@royal osprey - ive got a plan for using polished concrete as a floor and there’s plenty of wood veneer in places. So you recommend to slap a huge spherical and use granular ones for other objects?
royal osprey
Everthing should be inside at least one or things look dark. Then detail stuff to simulate different areas.

Hi! I'm working in archviz project. I bought some wc assets. They seem to be properly unwrapped but when I lightbacke it this is the result
Does anybody know why this grayed zone appears and how can I avoid it?
royal osprey
are you in production in the bake settings? @broken radish
@wicked willow the thing that sticks out to me is that the kitchen/dining area is too dark.
hollow canopy
^ more bounces?
wicked willow
@royal osprey hmm yeah I was feeling that too .. I have the Indirect Lighting Bounces already set to 10
I'll try higher. I just don't want every thing else to get too bright too
hollow canopy
You might wanna adjust your sun/skylight indirect intensity before adjusting the world indirect bounces
Could win there cheaply
wicked willow
I bumped up the light mass bounces to 100 and it looks pretty much the same!?
I
I'll try the Sun & Skylight indirect intensities next
wicked willow
adjusting the skylight didnt seem to do anything either
how does this look ? i doubled the indirect sunlight intensity
wicked willow
that would a light map resolution fix right?
limpid pivot
Does anyone know how to help me with my building lighting problem? Whenever I build lighting for my map it doesn't work

@limpid pivot what exactly happens when you try ?
limpid pivot
So it will say it failed and none of the lighting get's built. It stays on 0 for like 15 minutes.

while copying reflection capture i m getting out of memory error. i tried (https://www.thewindowsclub.com/increase-page-file-size-virtual-memory-windows) but again same issue. my pc having 32gb of ram and 2 gtx 970 graphic cards. please suggest me the solution.
thanks in advance.
hollow canopy
@signal narwhal - that card is 4GB iirc. So 4G is sort of your hard limit even in SLI since memory of GPU’s doesn’t double in crossfire or sli, it’s just shared in parallel so the same number of effective memory. Secondly - you may need to adjust your texture sizes, especially since reflection captures with a high resolution eat a lot of VRAM. A scene with refcaps with 2048 res will use 256mb per reflection capture so you max your video memory out with just 8 captures. And that’s not counting other stuff. That’s how I understand it. I’m not sure how UE optimisations come into play here. But also there are reported bugs about that message being sporadic and going away with engine restart or scene cleanup so 🤷♂️
signal narwhal
<@499526715580874752> - that card is 4GB iirc. So 4G is sort of your hard limit ...
will try reducing texture size, some of my textures are 4k right now.. Thank you..
hollow canopy
Well try reducing the reflection capture texture sizes first before reducing your main materials / textures
signal narwhal
ok
signal narwhal
Well try reducing the reflection capture texture sizes first before reducing you...
hi i reduced all of my texture size 4k to 2k still m getting the same error
hollow canopy
You reduced it for the actual reflection captures too or just textures you use on meshes ?
signal narwhal
reflection capture m not using any texture. most of the mega scan texture i downloaded was in 4k i reduced all the to 2k
@hollow canopy
hollow canopy
Here. Reflection captures grab a picture of whatever they capture as a reflection so they do rely on that and the resolution of it.
That’s what I was talking about.
It’s in project settings.
hollow canopy
Put it to 512 or something.

Hey all~ first time posting, I have a question regarding with Revit datasmith to unreal plugin. I import my datasmith file into unreal and attempt to switch the revit materials that came over to pbr materials and they are at the incorrect scale. what would be the appropriate solution or method to solve this?
sand cloak
proven berry
Hey all getting a weird issue in 3DS Max -> UE4 via Datasmith. Imported two other scenes flawlessly but this one seems to be behaving really strange
The materials didn't carry correctly, they all have an automatic texturecoordinate node set to scale 300x300 for some reason, and applying any materials to objects, even fresh ones I've just created, won't show up on the object itself
They do show up in reflections though;
See the floor there should have a wooden texture applied, but it just looks almost plain grey everywhere except for the reflection

Anyone have any opinions on the best wireless VR headset?
royal osprey
@leaden axle there is really no such thing, there are stand alone headsets and wireless adapters for cable based VR headsets.
You can't go wrong with a Vive pro with the wireless kit. If you want truly portable go with the Quest2, the lenses and screen are fantastic, but the 3d environment has to be optimized for a high end mobile chip. Having said that you can remove that limitation and also use the quest wirelessly with PC-VR even if it's not officially supported. You need a good wifi 6 router, some paid software and time to configure it all.

Emerging business models for Arch-Viz??
Can anyone share examples of links to architects, builders or real estate developers using configurable unreal models of buildings or communities to market real estate directly to buyers BUT also linked to prefab manufacturers so "ordered" buildings can offer realistic pricing and fast manufacturing and delivery? This would be similar to how unreal is increasingly being used in the automotive and other industries.
I ask this as a manufacturer of prefab wooden buildings in Oregon. I see this sales "model" as inevitable and imminent and want to help make it happen faster. The booming US West Coast housing market is also the ideal region to lead this for multiple reasons but it requires disruptive change in multiple professions.
There are multiple intellectual property, who pays, who owns, who is responsible and contractual challenges but also nearly unlimited opportunities.
I am in discussions about this with the Epic AEC team and also a group of architects and real estate companies.

Hi quick question, I'm new to Unreal Arch Viz and I was wandering about what can I do with the collisions. I have hundreds of individual objects in my scene, do I need to go one by one and make them custom collision? Is there a better way to solve this problem ??
royal osprey
@idle mulch
idle mulch
oh yes I didnt mention it, I want to make the character interact with the environment, and with the auto generated its not possible, to be able to do that I need to make it custom one by one
I found a way I believe though, I'm going to use the blocking volume, haven't tested it though
drifting drift
any ideas why bringing the mesh onto the fps-template "ground" is causing the textures to get "bleached"? I moved it halfway to illustrate the effect. The post process volume and lighting boxes are all large so even the left side that is out of the "ground" area is still within the lighting box
drifting drift
ok I figured out that it's the post process volume - if I disable it or delete it, the textures are then unaffected by ... whatever it is that post process volume is doing.
so I guess the question is - what's it doing? I like how the texture is when post process volume is disabled, however I imagine for photorealism I need post process volume.

greetings ppl 🙂 I have a question regarding skylight, raytraced reflections and GPU Lightmass, maybe someone here can help me 🙂
I have a scene with SunSky with all set to Static
My intention is to bake all light, and use only RT reflections. So, after GPU Lightmass bake, here's how it looks on editor: https://cdn.discordapp.com/attachments/221799195806400512/786929034369695744/unknown.png
but if I play : https://cdn.discordapp.com/attachments/221799195806400512/786929175495573565/unknown.png
so the sky doesn't seem to be affecting the light bake (nor the reflections in editor)
in realtime play, it seems to be working RT (there's some noisy stuff happening on the wall on that other room too, leading me to believe its RT raytracing)
raytrace AO and GI are disabled on a PP volume https://cdn.discordapp.com/attachments/221799195806400512/786929944466161694/unknown.png
any help or insight would be great 🙂 thx in advance 😉

Hello! does anyone know how to solve this problem? When ray tracing is enabled, leaves and trees have double geometry.

Is someone know how i can get rid of "Ran out of memory allocating" crash when i build light with GPU Lightmass ?
idle mulch
i don't know if this helps any of you, but for me helped with the crashes the reflection. In project settings mine was set to 2048, and I read in the documentation that the default needs to be 128. I set it to that number and didn't have any texture steaming pool problems or crashes. Still have problems with bakes ... I don't have crashes at least now 😛
hallow arrow
@dusk charm wait for 4.26.1 or compile from GitHub source
i have a fix for CPU memory there
4.26.1 will come later than usual
dusk charm
thanks a lot @hallow arrow
frank arrow
@hallow arrow i am using the 4.25.3 and I get this error...any idea?
The error message is Out of Memory
hallow arrow
thats an unfortunate limitation of how the old GPULM is designed
it is designed to be lightning fast in small scenes with medium num of lightmaps
and then completely breaks down in larger scenes due to memory
GPULM in 4.26 is redesigned to handle this much better, at the cost of 3-4x slowdown in raw sampling speed
frank arrow
But I read It needs Ray Tracing, no?
hallow arrow
yes, it needs ray tracing
frank arrow
Ok, thanks a lot for the answers, I really apreciate
idle mulch
@hallow arrow I'm a noodbie to this stuff now Im starting to get into it, sorry if I ask something too obvious because I dont get it 😅 . So you say thos problem will be fixed in the new update for 4.26 or what can we do form GitHub?? we download something from there?
Now I'm using gpu lightmass in 4.25 and my scene is relatively large so I have some of this problems. Firstly I got the texture streaming pool over, and then I got crashes like @frank arrow. So to conclude, for this things to be fixed we need to wait for the new update ??
and again sorry If I ask dumb questions I'm new to this stuff
steep ridge
@idle mulch, you should learn about Version Control in general. You won't need to wait for 4.26, but cherry picking fixes often isn't practical unless you really need a specific feature.
Anyway, how are people dealing with dynamic actors (changing entire wall sections) with static reflection probes?
doesn't seem to be great way to use static light builds with runtime switching sections if you have a lot of shiny materials that don't take planar
idle mulch
you mean Source Control I think, I found a webinar of unreal engine
l will have a look at it, seams important thnx !
steep ridge
@idle mulch It's the same thing.
How do Dynamic Material Instances work with static builds btw?
Oh, I guess they don't exist when you build.
Do animated materials?
idle mulch
You can do animated materials, like a tv playing a video but haven’t played with it yet to tell you in detail. Better someone with more experience answer that.

Can anyone tell me the reason for that? I am using Luoshuang's GPU Lightmass.Lightmap resolution is high.But getting those weird shadows.I baked it in production quality but still facing same issue
steep ridge
Hope someone can help. If I have a persistent level like collab_viewer_p, and i load in and out variations of my scene that are added as sublevels (bathroom A with red walls/ Bathroom B with green walls), what's the proper baking procedure? Do I load the sub levels in the editor and bake individually?
It's a little confusing because i don't want the sublevel's bakes to interact, which seems to be the standard use case.
steep ridge
Is there no way to force sublevels to use separate lightbuilds? Will I have to setup my level variants as diffirent levels that I open?
toxic lintel
What lightmap resolution do you guys like to use for larger architectural elements?
tropic flicker
Hi guys, I have a fairly general and possibly silly question. Once Im complete with an ArchViz scene and i want to use the level sequencer to output image files as the format for the video. Does FPS matter or will it not affect the image file smoothness ?
toxic lintel
@tropic flicker Depends, do you mean the FPS when the scene is rendering or the FPS that is set in Sequencer
If the former, no it won't matter. If the latter than it will affect the playback speed of the result
tropic flicker
Yep I meant the former! Great to know thanks 👍
royal osprey
@toxic lintel resolution is irrelevant, it's the texel density that is important. For arch viz I try to keep it just barely in the red. Shinny, transparent and dark stuff can have lower rez.
toxic lintel
@royal osprey Ahh thanks, I was unaware there was a Lightmap density view, I'll use that then

royal osprey
I had to make my own grass, I couldn't find any I liked either. Made up of a few different sized clups, made out of planes with color and alpha. The material had a world aligned texture to help with variation, the normals were tweaked so the light behaves more naturally and I had a system to applying it using several layers of foliage, each with different fade distances so it didn't fade out noticeably but it also remained somewhat responsive. Also near the edges I erased the main clumps and added smaller ones, so the grass doesn't poke through solid surfaces.

jaunty swallow
Hey all, anyone had the issue when trying to use the sunsky actor, with the physically-based 75000 lux intensity value for the sun, and the whole scene gets overexposed?
I've fixed up the exposure settings, so that it works... but only when the Sky Light is set to Static and has its light baked.
Problem is that I want it stationary, so that it can interact with volumetric clouds... There is a small island of well baked cubemap in the middle... even though the postprocess volume is unbounded
Anyone met and overcome this issue before?
I tried expanding the postprocess volume to the level's extents
but only the small circle in the middle stays well exposed
jaunty swallow
Or, rather, I've realised that it's that Real Time Capture doesn't work. Doesn't matter whether the sky light is stationary or static, so long as real time capture is not enabled... the scene is not overexposed
But what I don't understand is what is responsible for the well exposed part of the scene when real time capture is enabled...
jaunty swallow
ok figured it out I believe. Not sure exactly why it still doesn't work Stationary... but you either have to choose to make the Sky Light completely static, or completely movable, and not in between

@elder notch apologies in advance for tagging you -- I thought it would help me get visibility.
I've been given a CAD task - I have some pictures and potato quality videos of a bridge that's collapsed in my city. Job could go well up to the government. My task is to:
- Model and embellish said bridge
- Make it destructible
- Make a short cinematic of it
I'm not entirely sure about how to do this in Unreal (I know the PBT well enough to do basic CAD but I don't know much about destruction) and I don't know how much to charge for my work since I'm not a designer but a programmer. Any advice and pro tips will earn me money and boost my confidence towards future pursuits.

@raven atlas It looks good overal! Some things that stand out is to watch out with camera movement. You speed up the camera a lot and slow it back down aswell. This ruins the flow of the shots. One big part of critique is not to use a character in the scene specially not a character that is not animated when you showcase an animation. This destroys the reality of the scene and gives it an odd feeling. Your lamps emit to much light in my opinion. Beside the emission value they don’t actually produce light within your scene, keep that in mind that when you mimic a light source that it also has to look like it’s emitting light. If you look at the wall behind the lamp you would expect it to be overblown by the lamp. The exposure value as don’t feel right aswell it’s way to dark when looking through the window. Some easy tweaking in pp might fix that. I personally would bump up the overal reflection in some materials to really enhance the affect of the trim lights in the roof. I rlly like those!
Sorry for the late reply been quit busy 🙈

@pastel summit yeah bro been following on youtube , good job , i notice that my videos seem like they are lacking resolution , is it something to do with LOD or is there an issue that iam unaware of ?

Hello guys, the static meshes are coming black after building static light. Can anyone help me with this?
pastel summit
@raven atlas thanks 😊 you can increase the screen resolution in post processing under rendering - misc - screen percentage. I use it on a value of 200. You can also do it in the viewport. Besides I created a sharpness filter for the camera lens that makes it pop more
raven atlas
@pastel summit thanks a lot bro , u know u can add me , id like to know a bit more about you , also iam staring a project u seem good with critique and ur genuine too , message me ill run it by you maybe ull like it. that sharpness filter is also very good , man for a guy who knew unreal engine like 2 months ago iam still a bit overwhelmed , for a mechanical engineer , who somehow got involved in banking , i think my pace is okay , i just open unreal everyday for 3 to 4 hours after work , so far iam very excited about this technology and also iam excited about artificial intelligence , the open sourceness of it all.

Hello guys, the static meshes are coming black after building static light. Can ...
I think this is a bug happed to me once and I didnt figure out why
what mobility has your light source ?
void citrus
what mobility has your light source ?
static
I need to work with static lighting only as on mobile the dynamic lighting uses more gpu & hangs the app.
idle mulch
everything turns black ?
void citrus
no just few static meshes
void citrus
I have also tried lightmap coordinate index 1 but no change.
void citrus
try re importing those meshes
I have already tried this still same issue
void citrus
I have searched on net about it & come up with the fact that meshes which don't have lightmap uv channel(uv channel 2) turns black after light building but the meshes I am using all contains lightmap uv channel.
This is weird error I am facing, don't know what to do.
idle mulch
have you tried importing those assets to a new map ?
or project
if you make a test project and try bake them there and still turn black, your meshes will have a problem
if they don't turn black then your current scene might have a problem
void citrus
or project
I have also tested the meshes in blank level there also they come black.
Can you suggest some wayout for this?
idle mulch
I use 3ds max, and when I get weird things I use reset xform, Im not familiar with maya or blender if you are using them.
void citrus
yeah I am not to familiar with 3d tools, I am just trying to solve the issue in unreal.
idle mulch
In witch program did you made your meshes ?

go to the mesh settings , then under UV , select UV remapping
this happened to me before if was a sure fix
keep the default settings on the window and press ok
void citrus
In witch program did you made your meshes ?
the meshes have been bought from unreal marketplace.
void citrus
go to the mesh settings , then under UV , select UV remapping
okay thanks @raven atlas will try this fix.
void citrus
go to the mesh settings , then under UV , select UV remapping
I can't find anything related to uv remapping inside staic mesh editor.
I am using unreal 4.25.
I am only able to see UV Channel 0,1,2 under UV section inside mesh editor.

New to Blender. I made this scene from a tutorial on YT. How do I import this scene in UE? Getting "Degenerate tangents" or "overlapping UVs" errors. After baking in UE, all the textures look horrible.
raven atlas
can i see how it looks in UE ?

@raven atlas
After a bit of surfing i came to know about UV and Lightmap. Tried importing a single model and it worked Fine. But now that my scene has lots of models do I do it for every one of them?

limpid grove
Hi all, has anyone experienced this issue in a ray traced scene, where at a given distance the shadows of foliage elements stop displaying? Is there a distance parameter somewhere I can extend the visibility of the foliage shadows?
velvet viper
could be LOD's turning into billboards
limpid grove
I'll look into that thankyou 👍
limpid grove
If anyone else has this problem with ray traced shadow distance on foliage in the future I solved it by going into the r.raytracing.instancedstaticmeshes.lowscalecullradius and setting that to a higher number
mellow crater
Should I use Blender over UE4 for interior design?
Like walls and stuff? Doorways, etc
royal osprey
@mellow crater In Blender. this might change as the internal modeling tools are being improved, but right now, you should make your geometry in an external 3d app.

What is up with the reflection not moving in the second section. The stuck reflection is using forward shading.
Box reflection capture is lined up as best as I could

Does 4.26 now have luoshuang's GPU light mass?
I found the files on the forum but I thought it was now officially integrated into 4.26?
wicked willow
I installed GPU Lightmass and tried a render.. I cannot tell if its working this time. I dont see the progress window that usually open up .. do I have to do something to enable it?

Hey anyone here use 3ds max?
me
tawdry iris
can you help me export a 3ds file to fbx please?
west cloak
select object -> choose "export selected" -> save as *.fbx
tawdry iris
Well the thing is i dont have 3ds max
west cloak
aaah thats the point

I wanted to write that you need to prepare UV maps first. It can take a long time.
Depends on how complicated scene you have.

Just exporting is enough

I'm at work, can help you after 6pm
Oh i see.
Ok No worries
I will try getting someone else till you get back
If not I will msg you 🙂
west cloak
ok, good luck
royal osprey
@thorny mirage not per material, but in 4.26 you can do a object color pass. https://www.youtube.com/watch?v=RHemgKcIYMM

I've got a ruffled curtain I need to lightmap. I'm having trouble unwrapping it. Got any links to tutorials for similar curvy cloth items?

Hi, I'm looking for solution that helps me creates many of glass walls. They are of different lengths so the best would be a expanding procedural system that could hurry up my implementation to UE4. Any ideas?
an example from 3ds max:
velvet viper
does changing screen percentage affect the renderings done in sequencer/render queue?
royal osprey
@velvet viper I'm not sure it does anything. I did some tests with screen percentage at 200%, exported that, then compared it to exporting the images at 200% of the intended resolution and scaling them down in AfterFX. The scaled down full rez images looked much better.
