Roblox Texture Generator
Roblox Studio does not accept a generic PBR pack. SurfaceAppearance takes exactly four maps - ColorMap, NormalMap, MetalnessMap and RoughnessMap - and Roblox's own material enum decides how a surface reacts to light. This generator produces textures in that exact structure, so what you download can be dropped onto a MeshPart without any conversion.
- Built for Roblox
- 4 maps in engine format
- No watermark
- Commercial license
- 512px default
Most texture tools hand you five maps with engine-agnostic names, and Roblox Studio's material system does not read them. You end up with a SurfaceAppearance that ignores your roughness map or looks like flat plastic.
- ✓SurfaceAppearance 四图结构，直接挂载
- ✓MetalnessMap 已按 Roblox 双通道打包
- ✓预设对应内置 Material 枚举
- ✓附 Roblox Studio 挂载脚本

512px is the sweet spot for Roblox. Surfaces on mobile clients render small, and 1024px is plenty for a hero obby piece or a clothing item.

How to use these textures in Roblox
- 1
Generate the texture
Describe the material and generate. The default 512px is the safest size for Roblox mobile clients. Every preset above maps to a built-in Roblox Material enum.
- 2
Download the four maps
The export pack is exactly four maps: ColorMap, NormalMap, MetalnessMap and RoughnessMap. The MetalnessMap is already packed in Roblox format with metalness in R and reflectance in G.
- 3
Upload to Studio
Drag the four PNGs into the Studio Explorer, ideally into a folder under ReplicatedStorage or ServerStorage.
- 4
Add a SurfaceAppearance
Select the MeshPart, open Properties, add a SurfaceAppearance, then assign each of the four maps to its matching slot.
- 5
Match the Material enum
Set the Part Material to the enum that matches the texture - Wood, Brick, Concrete, Cobblestone, Sandstone or Metal. The enum drives the lighting response while the maps drive the detail.
- 6
Batch it with a script
When a scene has many repeated pieces, the setup script attaches a SurfaceAppearance to every MeshPart at once, which beats editing them one by one.
What's in the Roblox export pack
| File suffix | What it controls |
|---|---|
ColorMap | Base colour. Maps to SurfaceAppearance.ColorMap and Roblox's BaseColor. |
NormalMap | Tangent-space normals. Maps to SurfaceAppearance.NormalMap. |
MetalnessMappacked | Packed: R = metalness, G = reflectance. This is Roblox's own format. |
RoughnessMap | Surface roughness. Maps to SurfaceAppearance.RoughnessMap. |
为什么 Roblox 只需要四张图，而不是五张
SurfaceAppearance 没有 AO 槽位，也没有独立的 Height 槽位。环境光遮蔽在 Roblox 里由引擎的光照系统近似处理，你额外塞一张 AO 图进去不会有任何效果。
Height 图同样没有位置放 —— Roblox 用的是内置的几何凹凸，不是位移贴图。所以在这里导出 AO 和 Height 是浪费带宽，MetalnessMap 才是 Roblox 特有的关键图。
MetalnessMap 的双通道打包
Roblox 的 MetalnessMap 是一张图里装两个信息：R 通道是金属度，决定这个表面像不像金属；G 通道是反射率，决定非金属表面的镜面反射强度。
常见的做法是手动在 Photoshop 里拼通道，但多数人把 G 通道留成了黑色，结果非金属表面完全没有高光，塑料感极重。这里的导出已经按 Roblox 的约定填好了：金属区反射率 0.7，非金属区 0.5，直接可用。
Material 枚举才是真正决定观感的开关
很多 Roblox 创作者以为贴图能决定一切，但 Material 枚举才决定表面如何响应光照。Plastic 枚举会让任何贴图都带上塑料般的均匀高光，无论你的 roughness 图怎么画。
实践顺序是：先确定 Part 的 Material，再让提示词往那个材质靠。比如你要做砖墙，就把 Material 设为 Brick，然后提示词写 'red brick wall with mortar joints'。两者匹配时，SurfaceAppearance 的细节才能真正发挥出来。
脚本贴图（Scripted Texture）完全另一套逻辑
如果你的项目用的是 Scripted Texture 而不是 SurfaceAppearance，那贴图会被直接铺在砖块表面，此时贴图本身就是最终外观，没有 PBR 通道可言 —— 一张颜色图就够了。
这类场景下把生成结果当作普通颜色图使用即可，但要注意 Scripted Texture 的 UV 是基于砖块面片的，重复密度由 StudsPerTile 控制，通常 8 到 16 比较合适。
Avatar skin UV template
Roblox clothing does not use a tiling texture. Every avatar body part has a fixed region in a single "template" image, and the clothing mesh's UVs are mapped onto it. That means a seamless tileable texture is the wrong tool here — what you need is a colour image composed into the template's regions.
Classic 587×640 template layout
Roblox's classic template splits into a 2×4 grid of body regions. The face shares the head block, and the front/back split applies to the torso.
Region breakdown
- Head & face
0.00–0.50 (face front), 0.50–1.00 (head back)Head - Torso front
0.00–0.50, 0.50–1.00Torso - Torso back
0.00–0.50, 0.00–0.50Torso - Left arm
0.00–0.25Left Arm - Right arm
0.25–0.50Right Arm - Left leg
0.50–0.75Left Leg - Right leg
0.75–1.00Right Leg
How to use this generator for clothing
- 1. Generate the material you want — leather, denim, knit, metal trim.
- 2. Use the albedo as the reference for how each panel should look.
- 3. Paint each region of the template with the matching part of that albedo.
- 4. Upload to Roblox via the Avatar Editor (Shirt / Pants / Texture).

Roblox texture generator FAQ
How do I apply a texture to a Roblox MeshPart?
Add a SurfaceAppearance to the MeshPart and assign the four maps to ColorMap, NormalMap, MetalnessMap and RoughnessMap. Then set the Part's Material enum to match the texture - the enum controls lighting response while the maps control detail.
Why does my Roblox texture look like flat plastic?
Almost always the Material enum. Plastic has a uniform specular response that overrides the look of your roughness map. Switch the Part to the matching enum - Wood, Brick, Concrete, Cobblestone, Sandstone, Metal or Grass.
What resolution should I use for Roblox?
512 pixels for most surfaces. Roblox clients render on mobile hardware where a 2048px texture on a large obby piece wastes memory without a visible gain. Use 1024 only for a hero object the player gets close to.
Does Roblox support AO or height maps?
No. SurfaceAppearance accepts exactly four maps and neither ambient occlusion nor displacement has a slot. This generator therefore exports only the four maps Roblox can actually use, saving you two unused files.
Can I use these textures for Roblox avatar clothing?
You can use the albedo, but clothing needs a specific UV layout rather than a tiling texture. Use the color map as a reference for how each panel should look and paint the avatar template directly - see the avatar skin section above.
Is it safe to use in a published Roblox game?
Yes. Generated textures carry a commercial license covering games and products, with no attribution and no watermark.
How do I make a Roblox avatar skin from a generated texture?
Generate the material you want, then use the albedo as a visual reference and paint each region of Roblox's avatar template - head, torso, arms, legs - with the matching part of that texture. Then upload it through the Avatar Editor as a Shirt, Pants or Texture.
What resolution does Roblox clothing need?
The classic template is 587x640 pixels. Roblox also accepts larger source images that get scaled down, but the region boundaries must stay proportional, so working at the native template size avoids misalignment.
