Material Studio — Help & User Guide
Create and prepare textures in one workspace: PBR Generator produces material maps, Seamless Maker blends image edges for repeatable surfaces, and KTX2 Export packages maps for 3D workflows. Everything stays in the familiar dark Material Studio interface.
01 / Getting started
From source image to material
Load a texture: open PBR Generator and choose Load Texture, or drag one or more images into the app.
Choose a material preset: begin with Generic or select a surface type. Adjust individual maps by clicking their generated thumbnails.
Make it tileable: select Make Seamless or open the Seamless Maker tab. You can move the image back to PBR when finished.
Inspect in 3D: preview on a sphere, cube, cylinder, plane or your own OBJ/GLB model.
Export: download map images, ZIP, GLB or a KTX2 ZIP; batch export is available for multiple input images.
Tip: for a responsive first test, try a 1024–2048 px image. Larger images require more RAM and processing time.
02 / PBR Generator
Generate and fine-tune PBR maps
The generator estimates 10 supporting texture maps from a single image: Normal, Displacement, Bump, Ambient Occlusion (AO), Specular, Roughness, Metallic, Curvature, Edge and Cavity. The input image remains the Base Color reference.
Editing
Choose a material preset, select the maps to generate, then click a map thumbnail to adjust its controls. Additional maps and specialist adjustments are under expandable settings.
Multiple materials
Load multiple images, select a file from the project list, and keep settings per material. Use Batch ZIP, Grid GLB or Batch KTX2 to export collections.
Important: maps calculated from one photograph are visual estimates, not measured surface properties. Check displacement, metallic and roughness before production use.
03 / Seamless Maker
Seamless Maker — create repeatable textures
Seamless Maker reduces visible borders using horizontal and vertical blending. It is integrated in Material Studio and runs its image processing in a background Web Worker so the editor remains responsive.
Choose your source: click Load image, use Make Seamless from the PBR viewport, or choose a map in PBR → Seamless and click Use selected PBR map.
Adjust Blend Width: controls the width of the transition near image edges. Larger values blend more of the border region.
Adjust Pyramid Levels: controls the number of processing scales used in the blending method. Check both broad color transitions and fine details.
Adjust Sharpen: restores some perceived crispness after blending; excessive sharpening may create halos.
Check REPEAT PREVIEW: use Horizontal / Vertical to choose repetition directions and scroll the mouse wheel or use − / + / Fit to change the zoom while the image repeats across the full preview.
Finish: select Size and Format (PNG, WebP or JPEG). Use Export Seamless Texture to download, or Send Seamless to PBR to replace the selected PBR image and regenerate maps.
Source and result zoom
Each upper image has separate − / Fit / + controls. These change only the view, not the generated image resolution.
Original tool
The separate Seamless WebGL2 application uses a different GPU multi-band method. The integrated editor uses its own two-pass blending process.
Working with PBR maps: sending a processed map back to PBR regenerates the selected material's maps. If you need to preserve a specialist Normal or Roughness map unchanged, export a copy first.
04 / KTX2 texture export
Export KTX2 with control over size and mipmaps
Open the KTX2 TEXTURES panel in the PBR workspace. Select KTX2 ZIP for the active material, or Batch KTX2 for every loaded material. The ZIP includes individual .ktx2 texture files.
Setting
What it means
RGBA8 (offline)
Writes a valid uncompressed KTX2 container locally. Does not reduce GPU memory like GPU block compression.
UASTC / ETC1S
Optional compressed modes. Require a network-loaded encoder; availability depends on the browser and encoder service. UASTC prioritizes quality; ETC1S typically prioritizes compact assets.
Max resolution
Keep source resolution or limit the longest image dimension (512–8192 px).
Power of 2
Keep dimensions, or round dimensions up/down to powers of two for compatible pipelines.
Mipmaps
Generate progressively smaller levels to improve texture sampling at distance.
Flip vertically
Flip image orientation when the destination pipeline expects it.
Include Base Color
Include the original color texture alongside generated maps.
Enabled maps only
Export only the PBR channels currently enabled in the map list.
Color correctness: Base Color is exported as sRGB; numeric maps such as Normal, Roughness and Height use linear data. For small downloads or GPU compression, select a working compressed codec or use the dedicated WebVRDev KTX2 Converter.
05 / Real-time preview
3D Preview — evaluate materials on geometry
Preview generated textures on a sphere, cube, cylinder or plane, or load a supported OBJ/GLB model. Left-drag rotates the camera, right-drag pans, and the mouse wheel zooms. Touch gestures are available on supported devices.
Adjust Tiling to repeat the texture and Displace to preview height-based geometry. Select Studio, Day, Sunset, Night or Drama lighting. In the Light Rig panel, enable Softbox, Warm Fill and Rim Light and adjust their shared intensity. Floor can be toggled separately. VR/AR and advanced effects remain available under Advanced Preview.
06 / Export and project workflow
Save textures for your 3D pipeline
Images & ZIP
Save individual texture maps or export all enabled maps in a ZIP. Choose PNG, JPEG or WebP under Settings for standard image output.
GLB & Grid GLB
Export a GLB model with embedded textures. Grid GLB collects several material samples into a single scene for inspection or comparison.
Batch export
When multiple source images are loaded, export multiple materials with Batch ZIP or Batch KTX2. Separate folders keep identically named materials from overwriting each other in a KTX2 ZIP.
Share
Use Share to publish a link to Material Studio on supported social networks. Your source images are not attached to that shared link.
07 / Installation & privacy
Use Material Studio as a web app
Install from the browser when the Install App button is available. Supported browsers can run previously cached app files offline; some resources may still require a network connection. On future online visits, the installed PWA checks for updated files. An active editing session may show an update prompt before the page reloads.
Local PBR generation and integrated Seamless processing run on the device. Optional external KTX2 encoders, CDN scripts and fonts may need network access. Non-essential Google Analytics activates only after cookie consent.
Frequently asked questions
Can I use PBR, Seamless and KTX2 together?
Yes. Import a source or map from PBR into Seamless, create a repeatable result, send it back to PBR, check the generated maps and then export KTX2, GLB or ZIP.
Why is my KTX2 ZIP larger than PNG?
RGBA8 KTX2 stores uncompressed pixel data. Mipmaps add more levels as well. For a smaller GPU-compressed texture, use a compatible UASTC / ETC1S encoder and test the result in your target engine.
What do I do if Seamless appears to stop processing?
Use 1024–2048 px output while testing, wait for the status message, and check that your browser supports workers. You can also reset the Seamless settings and reload if the image is exceptionally large.
Do I need to install anything?
No, the website runs in a modern browser. PWA installation is optional. Some codecs and libraries may still need an online connection.
Can I import my own model?
Yes. Use Load OBJ/GLB in the 3D viewport and adjust the material preview. Availability depends on the model and browser.

▦KTX2 export — generate KTX2 textures from the current material or all loaded materials. Adjust output size, power-of-two scaling, mipmaps and vertical orientation. Native RGBA8 runs locally; optional UASTC and ETC1S encoding needs an internet connection.
⬡Integrated PBR + Seamless workspace — work with ten generated maps, custom 3D models, adjustable lighting and bidirectional texture transfer in one unified editor.
⬆PWA installation and updates — install from the browser, receive updates on future online visits, and apply them automatically when no materials are being edited. An open project is protected with an update prompt.
↗Sharing and discovery — use the Share panel; Open Graph, Twitter/X preview image, search metadata, sitemap and structured FAQ are included.
?Expanded user guide — clear instructions for Seamless blending, two-way texture transfer, KTX2 codecs, mipmaps, 3D preview, exports, PWA updates and privacy, with larger readable text.
🍪Material Studio stores interface choices on your device. Optional Google Analytics only starts after you choose Accept. You can decline and still use the editor.
