Someone just gave the 3ds Max viewport a serious visual upgrade.
And it costs just $15.
Meet xCavity, a new plugin that brings Blender-style cavity shading, MatCaps, and screen-space lighting effects directly into the native 3ds Max viewport.
No complicated material setups.
No OSL shader tricks.
No switching to an external renderer just to get a better look at your geometry.
Just install the plugin, select a viewport shading mode, and start modeling.
And honestly, this is one of those small tools that makes you wonder why the functionality wasn't already built into 3ds Max.
Here's what xCavity offers.
1. Blender-Style Cavity Shading
If you've ever used Blender's Solid viewport with Cavity enabled, you probably know how useful it can be.
Small surface details become easier to read.
Edges and creases stand out.
Complex hard-surface geometry suddenly becomes much more understandable.
xCavity brings a similar approach to 3ds Max.
2. MatCap Shading
Want to inspect your model with a clean, studio-style material?
MatCaps provide convenient lighting and material appearances without requiring a complete scene setup.
They're particularly useful for checking forms, surface transitions, and proportions while modeling.
3. Screen-Space Global Illumination (SSGI)
Here's where things get especially interesting.
xCavity includes screen-space global illumination, adding an approximation of indirect lighting to the viewport.
This can help objects feel more grounded and give models additional depth without performing an offline render.
There's also support for screen-space reflections (SSR) and diagnostic visualization modes.
4. Native Nitrous Viewport Integration
And this is arguably the most important technical detail.
xCavity works directly with the 3ds Max Nitrous viewport through DirectX.
It doesn't require assigning special materials to your objects or replacing your existing shaders.
Instead, the new shading options integrate into the regular viewport shading menu alongside familiar modes such as Clay.
The developer designed them to behave like native viewport styles.
No OSL. No material overrides. No additional rendering engine.
And because the processing happens through the viewport graphics pipeline, the result is designed to remain responsive during modeling.
5. Customizable Appearance
You're not locked into a single preset.
The plugin provides adjustable shading and post-processing options so you can tune the look to your modeling workflow.
Whether you're working on mechanical parts, product designs, detailed hard-surface assets, or architectural geometry, having better visual feedback can make a surprising difference.
But there's an important distinction.
SSGI and SSR are screen-space effects.
They use information available to the viewport rather than calculating complete physically accurate global illumination.
That means off-screen geometry, hidden surfaces, and complex lighting situations can produce limitations or artifacts.
This is a modeling and viewport visualization tool, not a replacement for V-Ray, Corona, Arnold, or Redshift.
And that's perfectly fine.
Because sometimes you don't need a physically accurate render.
You just need to see what you're modeling.
And that's exactly why I like this idea.
A good modeling viewport should make geometry readable, provide useful visual feedback, and stay out of your way.
Blender has offered some excellent viewport visualization tools for years.
And bringing similar capabilities into 3ds Max through a lightweight plugin makes a lot of sense.
Especially for artists who spend most of their time modeling rather than rendering.
The price? $15.
Not a bad proposition for something you might use throughout every modeling session.
Just check compatibility with your particular version of 3ds Max before purchasing.
