# Finish material upload (expert)

We provide guidance on how to use texture maps in PBR (Physically-Based Rendering) for high-quality rendering results.

**Path:** Dashboard > Corporate Library > Products > Finishes > Upload (Expert)

## Upload Initial Screen

* **Recommended Upload Order**: Any map can be uploaded first, but **Albedo (BaseColor)** we recommend uploading the map first.
* **Multiple file selection** then **drag & drop**to **batch upload**is also possible.
* **Supported file formats**: `.jpg`, `.png`
* **File size limit**: **Under 5 MB**

## Map descriptions by upload area

When uploading as an expert, you can upload a total of 5 maps individually.

### Albedo (BaseColor)

* **Role**: Represents the base color of the surface.
* **Characteristics**: Pure color information without lighting or shadow information

### Normal

* **Role**: Controls the direction of light reflection to express detailed surface texture
* **Characteristics**: A blue/purple-toned map using RGB channels

### Roughness

* **Role**: Controls the surface's roughness and reflectivity
* **Characteristics**: A grayscale map ranging from white (rough) to black (smooth)

### Metalness

* **Role**: Controls whether the surface is metallic
* **Characteristics**: A black-and-white map usually expressed as 0 or 1

### Height

* **Role**: Represents surface height information to emphasize dimensionality
* **Characteristics**: Grayscale map (more realistic effect when used with a Normal map)

{% hint style="warning" %}
All maps **tiling (Seamless Texture)** must be applied.
{% endhint %}

## Map creation and extraction methods

### Recommended tools

* Adobe Substance Painter
* Adobe Substance Designer

### Things to note when creating

* All maps must have tiling applied, and non-tiling maps may cause unexpected rendering results.

## Expert upload vs. standard upload

| Item                    | Standard upload                             | Expert upload                                          |
| ----------------------- | ------------------------------------------- | ------------------------------------------------------ |
| Number of maps uploaded | 1 (BaseColor)                               | Up to 5 (Albedo, Normal, Roughness, Metalness, Height) |
| Auto-correction feature | Provided (Roughness, Normal auto-generated) | Not provided – user uploads manually                   |
| Output quality          | Basic level                                 | High-quality PBR rendering possible                    |
| Recommended for         | General users                               | 3D professionals and designers                         |

{% hint style="info" %}
For general users, simply uploading BaseColor for a simple upload experience will allow Archisketch to automatically generate and apply Roughness and Normal through its auto-correction feature.
{% endhint %}

## Other notes

* **File name rule**: To clearly indicate each map's purpose, for example: `materialname_albedo.png` we recommend using this format.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.archisketch.com/guide/enterprise-en/manage-finishing/upload-finishing-expert.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
