OneClick Exporter - Free

Allows you to easily export your 3ds Max 2021+ scene with V-Ray or Corona materials and lighting into Unity realtime scene.

The Free version has everything needed to test how well your content could be converted.

Direct download link: OneClick Export v1.47
To install OneClick simply drag and drop mzp file onto 3ds Max's window OR use the main menu Scripting -> Run Script...

When the installation is successful, a new menu entry OneClick should appear:

OneClick Exporter - PRO

The Pro version gives you the maximum texture quality and more control over optimizations.

Please note that currently this is a BETA version. Not every scene can be perfectly converted without additional manual work.

A license key to activate the PRO version can be obtained here: u3d.gumroad.com/l/3dsmaxVray2unityPRO
One key can be used for several 3ds Max versions but on a single Windows system.
