Installation - Verge3D for Blender
Verge3D can run on top of Blender, an open source 3D modeling and animation suite, which should be installed first (versions 2.81, 2.80 and 2.79 are all supported). You can download Blender for free from the official website.
Download Verge3D for Blender for your operating system (.exe installer for Windows, or XZ archive for macOS or Linux).
Installation for Windows
Double click on the .exe file to run the installer.
There is a known issue on Win 10 when Windows Defender may refuse to run the installer (we are working on it). If you see a blue warning window like on the picture below, click the More info link:
and then press the Run anyway button:
Choose an installation folder that have enough permissions for reading and writing (or better leave it by default). Installing in a system directory such as "Program Files" or "Desktop" is not recommended.
Once the installation is complete, you may open Blender. If you had it running, be sure to close and open it again.
Open the Preferences window and go to the Add-ons tab. Find and enable the Verge3D addon, then click Save Preferences and close the window.
As of version 2.17, you may also launch the App Manager without running Blender by clicking on the desktop icon or using the Start menu.
Installation for macOS or Linux
Unpack the XZ archive to a directory of your choice. Make sure you have enough permissions to read/write in this folder. Installing in a system directory is not recommended.
In Blender, invoke the Preferences window by selecting the corresponding option in the Edit menu.
On the File Paths tab, find the Scripts field and make it point to the folder in which Verge3D is installed. Close the Preferences window and restart Blender.
Open the Preferences window again and go to the Add-ons tab. Find and enable the Verge3D addon, then click Save Preferences and close the window.
