# Finishing Material Upload (Expert)

This guide explains how to use texture maps in PBR (Physically-Based Rendering) to achieve high-quality rendering results.

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

## Initial upload screen

* **Recommended upload order**: You may upload any map first, but **Albedo (BaseColor)** it is recommended to upload the map first.
* **Multiple file selection** after **drag & drop**and **batch upload**are also available.
* **Supported file formats**: `.jpg`, `.png`
* **File size limit**: **Less than 5MB**

## 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.
* **Features**: Pure color information without lighting or shadow information

### Normal

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

### Roughness

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

### Metalness

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

### Height

* **Role**: Emphasizes depth by representing height differences on the surface
* **Features**: A grayscale map (more realistic when used together with a Normal map)

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

## Map creation and extraction methods

### Recommended tools

* Adobe Substance Painter
* Adobe Substance Designer

### Notes during creation

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

## Expert upload vs. general upload

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

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

## Other notes

* **File naming convention**: To clearly indicate the purpose of each map, for example: `materialname_albedo.png` it is recommended to use 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.
