From this guide you can learn how to configure 3ds Max viewport to match Verge3D look and feel, and how to use Scanline/ART rendering and the ActiveShade feature to obtain a reference image.
To enable better viewport preview in 3ds Max, switch from Standard to High Quality in the viewport settings:
Click Realistic Materials with Maps in the Materials submenu (this operation is required every time you add a new material):
Enable Environment Background in the Viewport Background submenu under Default Shading:
The above-mentioned settings are pre-enabled for the default cube project.
Viewport shading, however, does not always appear to provide an accurate approximation of the in-browser rendering - for instance, environment reflections ignore normal maps in the viewport, etc.
Verge3D rendering strives to be as close as possible to Scanline render if standard materials are used, and to ART render if physical materials are used. So you can preview your scenes in 3ds Max without exporting for quicker tweaking.
To select the renderer, click Render Setup... in the Rendering menu (F10):
In the window use the Renderer dropdown to switch between Scanline and ART:
To render a scene, click Render (Shift+Q):
Subsequently you can use the Render button to repeat your render:
For faster iterations, you can use the ActiveShade mode which automatically updates the render every time you modify a scene (works best with ART render).
You can enable ActiveShade in the Render Setup... window:
After that you'll be able to switch a viewport to ActiveShade mode:
This way you can achieve a better approximation of what you get in the browser, at a near real-time speed.
