Speed, flexibility and access to advanced image post processing abilities. Spotmask exports from mentalray world space, object space and camera space normal directions in raw and in clamped color space. This data can later be used to generate accurate reflections for light sources that were not there during the original render. This render element allows you to store the directions in which all surfaces are facing. 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 into wrong directions. It only works for scenes with a static camera. The default velocity render element doesn’t generate view-dependent data and completely ignores camera movement. While 3ds Max already offers 2 options to generate velocity data by default, Spotmask’s version offers a significant improvement for camera motion. Motion blur is without a doubt one of the most time consuming components in animation rendering.
With this image information you can access and alter each texture of your image or animation. This way an artist can modify color, blur, visibility or add any effect to selected areas of their rendered 3d world.ĭid you ever want to change the textures in your scene after it has been rendered – without rendering it all again? UV-Pass is the perfect solution for this purpose: just add the Spotmask UVW-Pass render element to mental ray and it will deliver you the necessary mapping information. Unlike Z depth buffering 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. The Spotmask world postition pass offers 3d artists the ability to better select and retouch any region of the image or animation sequence after it has been rendered.

This information can later be used to add modifications like transparency or coloration to objects based on volume instead of being uniform. Thickness is a render element that determines the volume thickness of objects over their surface. This information can be used during post-processing to detect and modify grooves and ridges on objects. It differentiates between convex and concave angles. The Curvature render element determines how strongly the surface of objects bends at any given location. Spotmask is a lightning fast and easy to use solution for the requirements of serious image and video composition workflows. These advanced output passes allow 3d artists to make flexible adjustments to their images and animations during post processing and compositing. Velocity Pass (velocity pass for motion blur post effects).World Position Pass (scene location information).Spotmask is a plug-in for Autodesk 3ds Max that renders additional precision render elements in mental ray.
