# 3DS Max

Glossi features a specialized 3ds Max import pipeline that preserves your V-Ray materials and settings while converting them for real-time visualization. This is particularly valuable if you have extensive 3ds Max asset libraries, as it maintains the look and feel of your materials while optimizing them for real-time performance.

The pipeline converts complex offline-render materials into PBR materials for real-time use. It works with many material setups and includes handling of non-PBR behavior, but the best results occur when materials are created within PBR standards.

### 1. Prepare Your Files

Before uploading, ensure your model is properly set up:

* **Organize your scene** — Keep the scene clean, focusing only on the objects you want to import.
* **Verify material assignments** — Ensure all objects have the correct materials assigned, following the material guidelines below.
* **Position at the origin** — Place your model at or near the world origin (0, 0, 0).
* **Use real-world scale** — Ensure your model uses accurate real-world dimensions.
* **Prepare variants separately** — For each variant (open/closed/propped states), prepare individual files.

### 2. Create a ZIP Package

3ds Max files are uploaded as ZIP archives:

1. Include your **.max** scene file.
2. Add all associated textures and assets referenced by the scene.
3. Ensure the ZIP contains all necessary dependencies.

### 3. Upload

1. Navigate to the **Models** section in your Glossi workspace.
2. Click **"Upload"** and choose your ZIP file.
3. Select **"3ds Max"** as the file type when prompted.
4. Confirm the upload.

The system will extract geometry and convert V-Ray materials to real-time equivalents. Once processed, your model will appear in your model library ready for use in any project.

### Processing Times

3ds Max files require more processing than standard formats due to material conversion:

* **Under 100 MB** — Typically 5–10 minutes
* **100 MB – 1 GB** — Up to 1 hour
* **Complex material setups** — Up to 2 hours for intensive V-Ray material conversion

> **Note:** Maximum ZIP file size is 1 GB. For larger files, contact your Glossi representative.

### Material Guidelines

For optimal V-Ray material conversion:

**Supported:**

* Standard V-Ray materials with diffuse, reflection, and glossiness properties
* V-Ray bitmap textures for color, reflection, and glossiness maps
* Basic V-Ray procedural textures (converted to bitmap equivalents)

**Limitations:**

* **Avoid Falloff nodes** — These often don't translate correctly to real-time materials
* **Use V-Ray Displacement Mod node** — Standard 3ds Max displacement is not supported
* **Avoid geometry-dependent nodes** — Such as V-RayCurvature, V-RayDirt, or VertexColor
* **Maintain consistent tiling values** — Ensure tiling is consistent across all inputs in a material
* **Limit complex material networks** — Extremely complex multi-layered materials may lose some details in conversion

### Best Practices

* **Test with smaller files first** — Start with simpler files to understand the conversion process before uploading large assets
* **Verify material compatibility** — Check materials against the guidelines above before packaging
* **Organize by variant** — Create separate files for each model variant
* **Review after import** — Check materials and geometry in Studio to ensure proper conversion
