3d-io Spotmask for Autodesk 3ds Max

World Position Pass

The Spotmask world position pass offers 3d artists the ability to better select and retouch any region of the image or animation sequence after it has been rendered.

Unlike Z depth, the world position data saves location data independently of the camera view: even if the camera moves or the object is out of camera view it still remains masked.

This way an artist can modify color, blur and visibility, or add any effect to selected areas of their rendered 3d environment.

UVW-Pass

Did you ever want to change the textures in your scene after it has been rendered – without rendering it all again?

UVW-Pass is your perfect solution: just add the Spotmask UVW-Pass render element to mental ray and it will give you the necessary mapping information.

With this image information you can access and alter each texture of your image or animation.

Velocity Pass

Motion blur is without a doubt one of the most time consuming components in animation rendering.

While 3ds Max already offers 2 options to generate velocity data by default, Spotmask’s version offers a significant improvement for camera motion. The default velocity render element doesn’t generate view-dependent data and completely ignores camera movement. It only works for scenes with a static camera. The G-Buffer velocity channel does consider camera movements and creates view dependent data but the camera motion is considered incorrectly and the blur moves in wrong directions.

Normal Pass

This render element allows you to store the directions in which all surfaces are facing. This data can later be used to generate accurate reflections for light sources that were not there during the original render. Spotmask exports normal directions in raw and in clamped color space from mental ray world space, object space and camera space .

Curvature Pass

Spotmask implements a very precise and customizable curvature render pass. The Curvature render element determines how strongly the surface of objects bends in any given location. It also differentiates between convex and concave angles.
This information can be used during post-processing to detect and modify grooves and ridges on objects. For example, artists can control two different topology properties in the final image: the geometry areas which are “bulged” (convex) or “inserted” (concave). It can enrich your final compositing with a beautiful AO-fake look or extra color details in creased mesh sections.

Thickness Pass

This render element determines the volume thickness of objects over their surface.
This information can later be used to add modifications like transparency or coloration to objects that considers their volume instead of being uniform.
