Unity

The A23D Unity Asset Importer enables you to send A23D assets from the website directly into your Unity project. The A23D Bridge panel shows download and import progress, lets you choose a custom asset folder, and can also import downloaded A23D assets from disk.

Frequently Asked Questions

Common questions about using A23D assets with Unity.

Do I need a plugin to use A23D assets in Unity?

The A23D Unity Asset Importer is the recommended way to bring A23D assets into Unity. It imports 3D models and PBR textures, then builds materials for your project's active render pipeline. The A23D Asset Importer is the recommended way to use A23D assets in Unity because it supports direct website imports, disk imports, automatic material setup, and organized Assets folders. You can still download files manually from A23D and import supported formats yourself.

Which Unity versions are supported?

The latest A23D Asset Importer is compatible with Unity 6 or newer, while also supporting Unity 2021 - 2023, across Windows, macOS, and Linux platforms.

How do I install the A23D Asset Importer for Unity?

Download the .zip from the Unity integration page, unzip it, then import the extracted .unitypackage through Assets > Import Package > Custom Package. After import, open A23D > Asset Importer to show the A23D Bridge panel.

How do I download an asset from the A23D website to Unity?

Open A23D > Asset Importer in Unity and keep the A23D Bridge panel open or docked. On the A23D website, choose Unity in the Software dropdown, choose a resolution, and click Send to Unity.

Where do imported assets live in my Unity project?

Imported assets are organized under Assets/A23D:

• Assets/A23D/3D_Models for imported 3D models.
• Assets/A23D/PBR_Textures for imported PBR texture materials.

Can I choose where website downloads are saved?

Yes. In the A23D Bridge panel, open Settings and set Asset Folder if you want to use a custom download location. Leave the field empty if you do not need a custom location.

Can I import an asset that is already on my computer?

Yes. Open the A23D Bridge panel, click Import from disk, and select the extracted A23D asset folder. You can also use A23D > Import From Disk....

Which file format should I download for manual use in Unity?

For manual imports, .fbx is usually best for 3D models. If you are using the plugin's website import flow, choose Unity on the asset page and click Send to Unity instead.

Which render pipelines are supported?

The plugin supports URP, HDRP, and the Built-in Render Pipeline. URP and HDRP use the included A23D shader graphs, while Built-in projects use Unity's Standard shader fallback.

Can I use A23D Decals in Unity?

Yes. In HDRP, create a Decal Projector or Decal Mesh and assign an HDRP/Decal material with the A23D color, normal, and mask maps. In URP, enable the Decal Renderer Feature in your URP asset and use a URP Decal Projector with the A23D textures. In Built-in, place the decal as a quad just above the surface with a transparent or alpha-cutout shader.

How do I use A23D IES lighting profiles in Unity?

In HDRP, drop the .ies file into your Project and Unity will auto-import it as an IES Profile asset, generating a ready-to-use Light Prefab. Drag it into the scene or assign the profile directly to any existing HDRP Light. URP and Built-in don't support native IES import — approximate the distribution using a cookie texture on a Spot Light instead. For photometrically accurate results, HDRP is recommended.

What texture resolution should I use in Unity?

Use 4K for hero materials in cinematic shots, 2K for general gameplay/scene assets, and 1K for distant or background props. Use Unity's Texture Import Override per platform (mobile / console / PC) to dial down maximum size where needed without re-authoring textures.
