Second Life - PBR Materials vs PBR Overrides
In the current release of PBR/glTF for Second Life, there is a critical distinction between a PBR Material and a PBR Override. This video hopefully serves to explain the differences in a way that is easy to understand.
I'll explain a little more technically here, however.
PBR Materials are sent as HTTP/TCP asset requests to Second Life's CDN/"Asset Server". What is sent back is the glTF JSON, containing all glTF parameters. If the client already has the PBR Material cached on their system, it pulls the JSON from their cache. TCP packets have error checking and can retransmit.
PBR Overrides are any texture slot or parameter changes that happen to the PBR Material while edited on the object, e...

Second Life - How to Pack glTF Materials in Blender 4.2
Просмотров 1,2 тыс.5 месяцев назад
Note: I forgot set Opacity/Alpha to Non-Color. It's not a critical mistake, but it can cause alpha to be more/less visible than expected! PBR materials in Second Life use the glTF 2.0 standard. This means that each material needs to be 'packed' into a .glb or .gltf textures. Additionally, by packing your PBR materials into the desired format, you get access to lossless normals, ensuring your co...
Second Life - Probe Limitations (And How to Get Around Them)
Просмотров 7567 месяцев назад
Probes are powerful and critical for PBR content, but they do have limitations. This video will demonstrate these limitations and explain some workarounds. Remember: Probes are meant for 'good enough' reflections. Being somewhat inaccurate is ok!
Second Life - Reflection Probe Cutoff
Просмотров 5317 месяцев назад
Sometimes your room is too busy around its center to get a good probe bake. Thankfully there's a tool in your toolbag for that: Probe Cutoff! By using this value, you can exclude objects from rendering based on how close they are to the centerpoint of your probe! This video will demonstrate and explain use cases for this.
Second Life - Reflection Probe Ambience
Просмотров 1,2 тыс.7 месяцев назад
Sometimes an area might end up too dark for one reason or another, Probe Ambience can help fix some of these issues or can be used in various ways to enhance a scene. This video will demonstrate the use of and various effects of adjusting probe ambience both on the probes and for the environment settings themselves. The viewer used is Alchemy Viewer, it is similar to the Linden Lab's client, wi...
Second Life - How to Set Up Mirrors
Просмотров 2,1 тыс.7 месяцев назад
Reflection probes are meant for general, 'good enough' reflections. If you absolutely need accurate reflections, (such as for a mirror), you'll need to use a mirror probe. In this video, I'll demonstrate how to make a mirror, and the differences between a static and dynamic mirror.
Second Life - How to Set Up Reflection Probes for PBR
Просмотров 7 тыс.7 месяцев назад
Reflection probes are a critical part of the PBR (Physically Based Rendering) Pipeline in Second Life. Without them, your scenes and objects can look washed out or incorrect in various ways. This video demonstrates a general process of setting up reflection probes within an example scene. The viewer used is Alchemy Viewer, it's similar to Linden Lab's viewer, with some tweaks, but the general w...
you forgot to show how you made that first reflective prim. I tried to make a high gloss one and then follow your tutorial, i cannot make it work. Maybe it's some bug in firestorm ?
Zan, would it be possible to add you on Discord? I have a question about clear-coat. I don't know if it's possible to use in SL (I use Alchemy viewer) but have it masterfully crafted in Substance Painter. Is it a probe issue? Shader issue? Nobody is able to guide me in the right direction. Any help would be greatly appreciated.
I have a question. How can add a pbr terain-ground in your land? :/
Hi thank you for the video - I'm struggling to convert my already made materials as materials gpl that work in SL - I added the add-on and added that node in the tree node, but when I upload my file in SL no nothing comes up in the different textures... Would it be possible to reach you on discord or somewhere else for help/me to share my tree node? I would be happy to pay for services/a lesson!
Thank you. Now if only I can figure out why my blog pictures are fuzzy from far away on a new expensive gaming laptop:D
Thankyou!
Mostly great tutorial you covered almost everything but missed one setting that will throw all the values of everything out of whack. If you read SL wiki on PBR it says Under: Scene > Render Properties > Color Management, Set: Sequencer: Linear ACEScg and View Transform: Standard. The sequencer particularly is super important, its what's used to convert or define the textures color space adjustments when its packed/exported. If you don't do this it will use the default sRGB as sequencer so values will be interpreted wrong since SL GLTF expects ACEScg.
Tap Quentin here. Thank you for creating these videos, particularly this one. Mac OS does not have a glTF packer, and the glTF packer does not have a Mac Version. Blender is a good alternative.
Only in SECOND LIFE you can find the mindet of " It is not meant to be ACCURATE - they are meant to be GOOD ENOUGH " Just like everything LL ever touches.
You should script your videos so you don't stutter and stammer as much
ahh I lost my probe yes I did the search I can see the light not the probe
Thank you so much for this info..really helpful
so ive been trying this...I am using alchemy but the thing is...the size of my image comes out really small in the reflection how do i fix this?
As clear as mud
oh my god thankj you so much im gonna CRY
When I do this, nothing happens. Why is that? Does the sphere need a PBR material on it?
I see upload fees zero, is that because you have Premium Plus account?
Yep! I have P+
Zanibar, this is priceless, thank you so much. I was near in tears because my photography stopped looking well with the PBR changes and all the near non-existent shadows. My home actually has them now! it looks beautiful now, my pond looks deep and realistic! I cannot thank you enough!! p.s. absolutely WILD to me this knowledge is not spread wide like fire by LL themselves because if you want your home to look well, you gotta get down to business you don't even know about. Oof!
literally same situation with me. i have been so distraught trying everything in phototools...
Is this the only viewer where you can use probes?
The official Second Life Client and Firestorm 7.x.x are PBR clients and are able to create and modify probes, though the workflow may be slightly different.
Thanks for explaining the difference.
Awesome! Thank you))
Does this mean if you make any adjustments to the PBR material's parameters, i.e. adjusting metallic or roughness, in world that it constitutes as an override as well?
Correct, though adjusting those parameters should be relatively small, the large overrides are the UUID overrides.
Great info
Where did the ambient occlusion file come from It wasn't in the fence 008a zip? it seems you downloaded it at a separate timeframe. Funny enough if I download rust 007 , It is provided in that zip.
Ah sorry, I should of mentioned that I repurposed the alpha image as the AO just so I had a complete set to work with.
@@NivenGe Awesome, Ty Zanibar. The videos are great and would love to see some more GLTF stuff in the future. Your tutorials are on point, never knew I could drag and drop into into the viewer.
@@NivenGe hello I am of the dumb side :D what does it mean "repurposed the alpha image as the AO" - you duplicated and renamed one of the 008A files? In this case which one? Ty, sorry, ty, sorry again :)
@@NivenGe Confused here. How do you repurpose the alpha image? Which one is the alpha image, and how do you repurpose it? I'm stuck at this step.
Thank you
Thank you
I Learned something today, thanks for the efficient teaching bit ♥
wow thank you
Thanks!
This is awesome , keep them coming. I'm loving these videos
😵💫

great tutorial...sucks that it needs os many workarounds to even make the changes work to look properly
It's not so much workarounds as the introduction one of the more difficult parts of a level designer's job, setting up reflection/lighting probes. Aside from the ultra-modern games, all the pretty lighting and reflections you see in your favorite games were accomplished using reflection and light probes in their engine of choice, and they were just as tedious as it is in Second Life to set up.
Thankyou for making a clear and direct tutorial!
Hm only for Alchemy ...
Huh? In Firestorm you have to increase the ambiance on the reflection probe for it to work. FS defaults it to 0. The range is 0 to 1. Set it to anything other than 0 and you'll see it where the reflection probe touches the ground (it HAS to touch the ground to be seen).
Thx for the video. Windlight needs to be PBR format too to have these shadows working? Cause i tried on my land and i see no shadows... maybe my windlight is not PBR...
Your Windlight/EEP makes no difference. In Firestorm you have to increase the ambiance on the reflection probe for it to work. FS defaults it to 0. The range is 0 to 1. Set it to anything other than 0 and you'll see it where the reflection probe touches the ground (it HAS to touch the ground to be seen).
I would suggest making sure to have a PBR-ready environment, as it will have Probe Ambience set to a proper level. Using a legacy environment may cause lighting to be odd in some situations. You may also want to check to ensure probes are enabled in your graphics settings. You'd find them in Preferences > Graphics > Advanced Graphics and they should be called something similar to 'Probe Coverage'. You'll want at least Manual, but I'd try out Manual + Terrain or Everything.
This is really cool! I just wish SL was smart enough to automatically add correct lighting instead of us having to do it ourselves.
That's literally what this does. This is how every video game does it. SL just caught up.
The games industry hasn't figured out how to do this, either. Their solution was to use raytracing instead of all this manual work. Unfortunately, raytracing is extremely expensive to render and requires very modern hardware, which would be a hard block to most of SL's users.
its actually impossible for SL to do this automatically. All the content here is user-generated. And even then, doing it yourself allows for control over how your scene looks
YOU make the best videos!!!! thank you
Thanks for the video series! Would it be possible to record the next ones at 1080p? Current 720p makes it difficult to read menu texts, floater text, etc.
I subbed because your videos are legit teaching me how to incorporate this stuff in to my next build and the firestorm video was just hurr durr mirrors derp derp fin.
Great tutorial thanks a lot ❤
Nice Tuto man! Thank you very much!
Mr Zanibar, what ao is that? :O
it's too bad you can't mirror a mirror, 🤔 but the reason why is quite obvious - as fun as a house of mirrors would be, the computer rendering it would not find it amusing (And then probably run out of memory) 😅
Cool video, I actually didint know you could double up probes like that for shading effects.
Amazing video and very informative. You taught a few things i didnt know about.
Well, I can say that today I learned something new. Just discovered your channel and you can add me to your list of new subscribers. Looking forward to learning many other new things regarding PBR.
Thanks for putting this out, made it easier to see the differences with and without the probe
Oh, lawzy! OK, looks like I'm going to have a lot to learn! This is some complex stuff. Thanks for the video!
Thanks, but what about an entire sim?
