# Finish material upload (expert)

This guide explains how to use texture maps in the PBR (Physically-Based Rendering) method for high-quality rendered results.

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

## Initial Upload Screen

* **Recommended Upload Order**: You can upload any map first, **Albedo (BaseColor)** but we recommend uploading the Albedo (BaseColor) map first.
* **Multiple file selection** after **drag & drop**with **bulk upload**is also possible.
* **Supported file formats**: `.jpg`, `.png`
* **File size limit**: **Under 5MB**

## Map descriptions by upload area

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

### Albedo (BaseColor)

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

### Normal

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

### Roughness

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

### Metalness

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

### Height

* **Role**: Expresses surface height information to emphasize a sense of depth
* **Feature**: A grayscale map (more realistic when used together 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

### Notes when creating

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

## Expert upload vs. general upload

| Item                         | General upload                                       | Expert upload                                          |
| ---------------------------- | ---------------------------------------------------- | ------------------------------------------------------ |
| Number of uploaded maps      | 1 (BaseColor)                                        | Up to 5 (Albedo, Normal, Roughness, Metalness, Height) |
| Automatic 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, to offer a simple upload experience, Archisketch automatically generates and applies Roughness and Normal when only BaseColor is uploaded through its auto-correction feature.
{% endhint %}

## Other notes

* **File naming rules**: To clearly indicate the purpose of each map, 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.
