I haven’t found many tutorials that really cover matte fabrics. I also get the feeling that a lot of creators still texture more or less in a “legacy mindset,” because honestly it’s just much easier to get something flattering and consistent from sim to sim.

But I’m not trying to start another “legacy vs PBR” debate here. I’m mostly looking for insight and feedback.

I’ve done a lot of clothing tests lately, and until now I’ve been following the “proper” workflow everyone recommends:

• very clean base color

• no baked shadows

• no painted highlights

• no muddy lighting information in the diffuse

Basically, a neutral albedo and “physically correct” PBR workflow.

Here’s the result. still a bit soft/flat sometimes:

In midday legacy it's just dead, And along with it, a good part of the texture work too.

So I ended up doing the thing you’re supposedly never meant to do: hybrid PBR. Yes, heresy, I know.

I made an other export for a PB , then grabbed the 2D view, and reintroduced some very subtle gray shadows into the diffuse. Nothing extreme, just enough to give the fabric a bit more presence and depth again.

And honestly… I kind of prefer the result.

Here’s how it looks under midday:

And it also comes back to life under midday legacy :

Of course it doesn’t work perfectly with every windlight. Sometimes you still run into the same issues as with a fully neutral diffuse. But overall, I feel like it survives oldschool environments and non-PBR-friendly sims a bit better.

So I’d genuinely like to hear how other creators handle this:

• How do you approach matte fabrics?

• Do you stay fully “physically correct”?

• Or do you cheat a little ?

Is there a good non video tutorial anywhere?

Edit - found out what the problem is, I needed some kind of C++ file...
Maybe this will be useful to somebody else one day....

I tried every setting in Graphics but produced no change.

Sometimes setting draw distance very low such as 20 can reduce the length or even remove this beam reflection but this is not a useful fix.

I make this topic in PBR, but it could be for texturing in general.

Maybe my question stupid, but turns out I don’t really understand how to control pattern scale inside UV islands on a 1024 map. I’d rather avoid 2048, but at 1024 my patterns look macro.

Yes, I can tile in SL and it looks good, but then it feels either limited or heavy if I need tons of material slots just to texture different areas.

I want to add seams, Topstitching, folds, so I have a normal map with that , but fabric textures also have their own weave normal. So what’s the correct workflow? Sculpt seams into the mesh?

II tried to blend a 1024 seam normal with a tiled ×8 fabric normal in Blender with nodes then only to realize the tiling doesn’t export anyway.

So I have a jacket that isn’t a jacket, maybe a bolero...

What is the cause? What is the fix?

Now that I’ve bought a PBR Skybox, I’m looking for PBR-compatible windlights. Can anyone recommend some of the best PBR windlights available right now? Free or paid options are both welcome.

Thanks in advance!

I wrote the following guides:

Reflection probes and You - https://docs.google.com/document/d/18ut5mR_S9sAYDwWvFHNpRqrJ31y2hpqVSZHd8sbeua4 which explains the basics of reflection probes and how to use them in your builds, and also how to make mirrors.

PBR, BP, glTF and You - https://docs.google.com/document/d/1VBz5Fdg1VJt6Y4h7TPOx2-uLnY756HqXQrtBWBmEdYU which explains PBR materials for non-creators, and people who like to mod their items. (Though it does have explanation of the overrides at the end, which is useful for creators)

Is this a fixable problem? I notice that it doesn't impact mirrors proper. Is there a workaround (other than putting a mirror where one wants to see some reflection, something I've actually done a few times)?

Is there a Canny for this? How likely is LL to actually do something about it? Or is this another instance of their half-assed incomplete implementation, and a problem that will gather dust on a shelf until they get to it "soon"?

Apologies if I sound annoyed about this, but I am actually pretty annoyed about it. PBR offers some worthwhile advantages to photographs, but this effectively cancels out a big one.

I noticed something while making PBR materials with a lot of convex/concave detail:
your normal map can start to look “lost” if the roughness map treats the whole surface as one flat, uniform value.

When roughness doesn’t reflect the micro-shapes in the texture, the lighting doesn’t “catch” the normal detail properly — so all those nice peaks and troughs just turn into mush under the light.

You can make the material read much better by adding a bit of micro-variation to the roughness.

What I do (and it works consistently well) is:

• take the AO map
• invert it
• blend it into the roughness using a Screen blend (or the equivalent in your tool) I usually run around 40% mix

This does two things:

1. Brightens roughness in the concave areas (where light scatters more)

2. Keeps roughness tighter/darker on the convex peaks (where light reflects more cleanly)

The result:

• your normal map doesn’t get drowned out

• the material has more visual depth

• the highlights break more naturally

• and the surface reacts to lighting like an actual physical material rather than a flat sheet

It’s a small step, but it makes a huge difference on anything with sculpted or height-driven detail.

Quick heads-up for anyone mixing “old SL habits” with modern PBR: Hybrid PBR (baking lighting, AO, shadows, highlights into the albedo) is exactly how you sabotage the whole point of physically-based rendering.

Reason: conservation of energy.
PBR assumes your albedo is pure surface colour. The renderer then handles all the light transport on top: reflections, shadows, diffuse, specular, everything.
If you bake lighting into the base colour, you’re forcing the renderer to stack new lighting on top of fake lighting you already painted in. That means:

• your dark baked shadows get darkened again → crushed detail

• your bright baked highlights get boosted again → blown-out hotspots

• your material will look wrong under every environment lighting scenario

• reflections will read incorrectly because the renderer can’t “subtract” your baked brightness

• your asset will never match the rest of a real PBR scene

In short: baked light inside albedo violates energy conservation.
The renderer can’t magically “unlight” the pixels you painted. So the material absorbs or reflects more energy than physically possible, and your content ends up looking muddy, inconsistent, or weirdly shiny depending on the region’s probes.

If you want realism, consistency, and content that holds up anywhere — keep your albedo clean.

Hybrid PBR is tempting because it looks “nice” in a static viewport, but it falls apart the second SL actually lights it. Pure PBR will always win long-term.


likewise the old baked lighting way, using the substance painter Baked Lighting Environment Filter will break your content, and offering it as an alternative to PBR is a whole bunch of nothing. I really can't believe people are still doing this in 2025/6.

I have two questions about Roughness and Metallic maps that I am hoping can be answered here.

Question 1

So, I had sort of an "Aha!" moment a while ago. I had been making roughness and metallic maps for flat but somewhat "bumpy" surfaces -- for instance, rough plaster, or oil paintings that featured brush strokes that are reflected in the normal map -- in such a way that I'd decrease roughness (and sometimes increase metallic) for those parts of the Albedo that "stood out" and were likely to get more reflectivity from local light. In other words, I was essentially "baking in" shininess, when I should perhaps have been using a simple undifferentiated map for both metallic and roughness (because the differential shininess is not a function of the material, e.g., plaster or oil paint, but of its position relative to lighting), and letting the rendering engine decide more "realistically" what would be shiny. 

MY QUESTION: this strategy makes sense for objects that are "bumpy" because the mesh is made that way, but is this true also where the "bumpiness" is produced not by the mesh itself but by the normal map? I'm assuming that the answer is yes -- that the parts of a normal map that should normally be more reflective in natural lighting will, in fact, be more shiny if I'm not baking in differential roughness and metallic. But am I right?

Question 2

Assuming that one is working with a colour map that doesn't itself feature different bits that should be relatively more shiny than other bits (e.g., say, materials for a belt, where the metal bits like the buckle are going to be more metallic and less rough than the rest), why would one not simply use a blank white map for metallic and roughness, and then adjust these manually in editing by increasing the darkness of the "tint" (or whatever it's called) to get the look one wants? What advantage is there to producing actual maps for these, when doing so means one probably can't make them less shiny while editing?
